Environment Ministry Reviews Mitigation Measures to combat air pollution in Delhi-NCR

Environment Ministry Reviews Mitigation Measures to combat air pollution in Delhi-NCR
A meeting held in the Environment Ministry reviewed the mitigation measures to combat air pollution in Delhi-NCR.  The meeting decided that all agencies will be held accountable for implementation of the decisions taken.  Following detailed discussions, the following decisions were taken:

  1. Government agencies like PWD, DDA, DMRC and NHAI have been strictly directed to ensure that dust mitigation steps are taken at their construction sites.  Default by any of these organisations will result in action against the defaulting officers of these organisations.
  2. Dumping of Construction & Demolition (C&D) waste in DDA/Public lands should be stopped immediately.   DDA, MCD should prepare a list of approved dumping sites and ensure that dumping takes place only at such sites.
  3. All the four municipal corporations have prepared detailed action plans carrying out paving/greening on a large scale.  It was decided that this activity should be completed by October 2018.
  4. Process of procurement of mechanized road sweeping machines has been initiated by the MCDs.  It was decided that procurement and deployment of all machines should be completed by September, 2018.  It was also decided that all the roads where mechanized sweeping is possible should be brought under the same.
  5. MCD had formulated plans for procurement of water tankers.  It was decided that all roads where mechanized sweeping is not possible, should be covered with water sprinklers.
  6. It was decided that the daily deployment of mechanized sweepers and water sprinklers will be published on the respective website of the Municipal Corporations with the help of GPS data, so that the public is informed of the deployment details.
  7. The tendering process for remediation of landfill sites at Ghazipur and Bhalswa has been initiated and work will start in the next four months.

The review meeting was chaired by Secretary, Ministry for Environment, Forest and Climate Change, Shri C.K Mishra yesterday.  The meeting was attended by Chief Secretary, Delhi government, all Commissioners of Municipal Corporation in Delhi and other senior officers of Delhi Government.  Appreciating the work done by Delhi Government till now, the meeting also noted that a lot of work still remains to be done to ensure better AQI levels in Delhi.

World Water Day 2018: 22nd March, Theme, Celebration, Importance


World Water Day

Water is the very useful element of Nature by which every living being can survive. It is used to provide everyone to make their Body fulfill their Basic Needs.
World Water Day is used to celebrate by the people to handle and tackle every problem of Water to save and protect it for future use.
New The theme for World Water Day celebration of the year 2018 is “Nature for Water”.
It is used to celebrate on the 22nd March with most of the people to make every people aware of the Water Element in India and many other Countries.
Water is a type of Element which is vital for any Living being on the earth. Without it, no Living Being can survive.
So it is very necessary for the people to get the Water for every use like Drinking, Washing, Bathing and many more things. There are various things which fulfilled with the help of Water.
It is the Basic Source for any Living Being on the Planet of the Earth. Water requires for every people to save their life and to protect from any kind problems in their healthy functioning.

It is not okay for the people to waste the Water as it is most important for the people to make their every action to fulfilled in a better way.
It is used to stop the Fire when the Fire in some area takes place. People are more used to drink Water for their proper health as the Doctors also recommend it.
It is used to maintain the Natural Environment as it is One Element of the 5 Elements like Fire, Air, Water, Sky and Soil. These 5 Elements are very Important Elements as every Planet, and also the Living Being, as well as Non-Living Being, is made with these 5 Elements.
So Water is also a very Important Element from the 5 Major Elements. Water is responsible for the Blood Flow in every Body for every Living beings survival.
It is used to circulate the Blood in everyone’s Body for the functioning of the Body. It is used to make Food for the people as people cannot be able to eat the Raw Food for their survival as the Raw Food is quite difficult to digest and also it is tough to eat some Food. So to Cook Food Water is require for everyone to make and eat Food.
People Nowadays are more reluctant to save the Water for its future use. Water should not be wasted by the people as it is the Element which is used to perform every small as well as big activities in the daily life of the people.
Water is required by the people to Wash the Hands, Flush the Faeces, Wash the Clothes and importantly to drink it for their survival.
Water as a major Element is a part of the Body which contains almost 80 percent the Water in the Body mixed with the Blood.

A celebration of the World Water Day   

People are more ambitious to celebrate the World Water Day to make the people aware of the Water activities and to spread the knowledge of it to save it for the future use.
It is the kind of Element which provides every people to survive with proper maintaining the health of the citizens. It is celebrated on the 22nd March to get the people know about the Importance of the Water and its uses in the World.
So it is important to save the Water by using it with proper care and use to get every people Sufficient Water for their use.
Nowadays people are more reluctant to get a Qualitative Water for their Drinking purpose as the Qualitative Water will provide the people to maintain their Body properly in a better way.
Qualitative Water provides to make their Stable to work with better health to achieve any goals in a right time. Water is capable of making the people carry out every task with the proper completion of any work.
Most of the citizens in India use only Qualitative Water for their Good health as the Qualitative Water makes the people get them safety about many types of Diseases which can come into contact with the individuals with the Dirty Water.
A lot of Water should be drunk by the population in a Day as it will make them survive from many types of Diseases. Water is very useful for those people who have Low Blood Pressure and many types of Urine and Stone Diseases.
It is used to remove many kinds of Health problems from the Body of the people. It is used to maintain a proper health by which every people can complete their task with good hard work to achieve their Goal.
Nowadays People in India using a lot of Water for any unnecessary reasons like Holi and many another thing which is not good for the future.
So it is important for the people to save the Water for the future use of not wasting for the unnecessary use and using it only when it required for their activities.
There is 75 percent of the Water available on the Planet of the Earth. But only some percent of the Water can be used for their requirements and rest of the Water can’t be used as it is a Salty Water. So people should save much of the Water for their survival and also for many purposes.
Water is a major part of the Body of every Living Being. More than 80 percent of the Blood is made up of Water. So it is the vital part of the Body by which Body of the Living Being can function properly without any problem.
It is also used to break the Stones in the Body of the Patient who is suffering from the Stone Disease. Water carries everything to fulfilled for the people’s survival and that why they should save it with every possible ideas and plan.
The government has enforced many rules to keep the Water from its unnecessary to use of keeping it for future use.
It is tough to maintain and tackle some activities which are vital for the people’s survival. One has to take the pledge to save the Water in every Country to make it possible to survive it.
Water develops many kinds of activities to be performed to achieve a better task for the welfare of the people in every Country. So it is necessary to save much of the Water Element to provide every people to get their vital needs to fulfilled in a better way.
So it is time for the people to protect the Water from many harmful activities performs by the people in many Countries.
There are lots of people who are used to save Water and make it more Qualitative for the people for drinking and many purposes. So One should save Water for all the Necessary  Things.
Water maintains the Flow of the Blood in every part of the Body by which every people get can perform any task in a quick time. Water flows to all the parts of Brain, Stomach, Nervous System, Hands, Legs Lungs, Kidney, Eyes and many other critical areas of the Body.
People should drink that Water which is Virus and Germs free and this type of Water can help the people to maintain their Body better by which they can do any work with lots of Hard work and Concentration.
People are more curious to drink the Qualitative Water by which they can get much of the energy and necessary nutrients from it.
Today people use many types of Water Filters like Ro+UV Water Filter, Kent Ro Water Filter and many other Water Filters which purifies much of the Water for the good Health.
So Today it is important for the people to use the Qualitative Water Filters for making the people get the pure and clean Water for their drinking purpose.
Today in India, there are various Villages in which there is a problem of Water in many areas, and people are suffering due to the Water Shortage.
Water Filters used for developing much high varieties of purifiers in it by which people are used to getting a spotless and harmless Water for their good health.
People are more reluctant to have a Qualitative Water to make a better life of their Family and safety from the Dirty Water causes.
So People Nowadays uses lots of water for their Body to remain to maintain for a better amount of Time for doing lots of Hard Work in any Company.

भगवान और उनके वाहन

भगवान और उनके वाहन

हिन्दू धर्म में करोड़ो भगवान पूजे जाते हैं, पर क्या आप जानते है किस भगवन का कौन सा वाहन है देखिये और जानिये किस भगवान का कौन सा वाहन हैं

धन की देवी लक्ष्मी इनका वाहन है उल्लू

देवो के देव इंद्र इनका वाहन है हाथी

भगवान और उनके वाहन

महादेव शिव इनका वाहन है नंदी (बैल)

भगवान और उनके वाहन
भगवान और उनके वाहन

सूर्य देव इनका वाहन है सात घोड़े

 होते हैं भगवानों के वाहन पशु?

किसी भी मंदिर में जाइए, किसी भी को देखिए, उनके साथ एक चीज सामान्य रूप से जुड़ी हुई है, वह है उनके वाहन। लगभग सभी भगवान के पशुओं को ही माना गया है। शिव के नंदी से लेकर दुर्गा के शेर तक और विष्णु के गरूढ़ से लेकर इंद्र के ऐरावत हाथी तक। लगभग सारे देवी-देवता पशुओं पर ही सवार हैं।
आखिर क्यों सर्वशक्तिमान भगवानों को पशुओं की सवारी की आवश्यकता पड़ी, जब की वे तो अपनी दिव्यशक्तियों से पलभर में कहीं भी आ-जा सकते हैं? क्यों हर भगवान के साथ कोई पशु जुड़ा हुआ है?

भगवानों के साथ जानवरों को जोडऩे के पीछे कई सारे हैं। इसमें अध्यात्मिक, वैज्ञानिक और व्यवहारिक कारणों से भारतीय मनीषियों ने भगवानों के वाहनों के रूप पशु-पक्षियों को जोड़ा है। वास्तव में देवताओं के साथ पशुओं को उनके व्यवहार के अनुरूप जोड़ा गया है।
दूसरा सबसे बड़ा कारण है प्रकृति की रक्षा।

अगर पशुओं को भगवान के साथ नहीं जोड़ा जाता तो शायद पशु के प्रति हिंसा का व्यवहार और ज्यादा होता।

हर भगवान के साथ एक पशु को जोड़ कर भारतीय मनीषियों ने प्रकृति और उसमें रहने वाले जीवों की रक्षा का एक संदेश दिया है। हर पशु किसी न किसी भगवान का प्रतिनिधि है, उनका वाहन है, इसलिए इनकी हिंसा नहीं करनी चाहिए। मूलत: इसके पीछे एक यही संदेश सबसे बड़ा है।
आपको क्या लगता है? गणेश जी ने चूहों को यूं ही चुन लिया? या नंदी शिव की सवारी यूं ही बन गए?

भगवानों ने अपनी सवारी बहुत ही विशेष रूप से चुनी। यहां तक कि उनके वाहन उनकी चारित्रिक विशेषताओं को भी बताते हैं... भगवान गणेश और मूषक गणेश जी का वाहन है मूषक। मूषक शब्द संस्कृत के मूष से बना है जिसका अर्थ है लूटना या चुराना। सांकेतिक रूप से मनुष्य का दिमाग मूषक, चुराने वाले यानी चूहे जैसा ही होता है। यह स्वार्थ भाव से गिरा होता है। गणेश जी का चूहे पर बैठना इस बातका संकेत है कि उन्होंने स्वार्थ परविजय पाई है और जनकल्याण के भाव को अपने भीतर जागृत किया है।
शिव और नंदी

जैसे शिव भोलेभाले, सीधे चलने वाले लेकिन कभी-कभी भयंकर क्रोध करने वाले देवता हैं तो उनका वाहन हैं नंदी बैल। संकेतों की भाषा में बैल शक्ति, आस्था व भरोसे का प्रतीक होता है। इसके अतिरिक्त भगवान के शिव का चरित्र मोह माया और भौतिक इच्छाओं से परे रहने वाला बताया गया है। सांकेतिक भाषा में बैल यानी नंदी इन विशेषताओं को पूरी तरह चरितार्थ करते हैं। इसलिए शिव का वाहन नंदी हैं।
कार्तिकेय और मयूर

कार्तिकेय का वाहन है मयूर। एक कथा के अनुसार यह वाहन उनको भगवान विष्णु से भेंट में मिला था। भगवान विष्णु ने कार्तिकेय की साधक क्षमताओं को देखकर उन्हें यह वाहन दिया था, जिसका सांकेतिक अर्थ था कि अपने चंचल मन रूपी मयूर को कार्तिकेय ने साध लिया है। वहीं एक अन्य कथा में इसे दंभ के नाशक के तौरपर कार्तिकेय के साथ बताया गया है।

मां दुर्गा और उनका शेर
दुर्गा तेज, शक्ति और सामथ्र्य का प्रतीक है तो उनके साथ सिंह है। शेर प्रतीक है क्रूरता, आक्रामकता और शौर्य का। यह तीनों विशेषताएं मां दुर्गा के आचरण में भी देखने को मिलती है। यह भी रोचक है कि शेर की दहाड़ को मां दुर्गा की ध्वनि ही माना जाता है, जिसके आगे संसार की बाकी सभी आवाजें कमजोर लगती हैं।

मां सरस्वती और हंस

हंस संकेतों की भाषा में पवित्रता और जिज्ञासा का प्रतीक है जो कि ज्ञान की देवी मां सरस्वती के लिए सबसे बेहतर वाहन है। मां सरस्वती का हंस पर विराजमान होना यह बताता है कि ज्ञान से ही जिज्ञासा को शांत किया जा सकता है और पवित्रता को जस का तस रखा जा सकता है।
भगवान विष्णु और गरुड़

गरुण प्रतीक हैं दिव्य शक्तियों और अधिकार के। भगवद् गीता में कहा गया है कि भगवान विष्णु में ही सारा संसार समाया है। सुनहरे रंग का बड़ेआकार का यह पक्षी भी इसी ओर संकेत करता है। भगवान विष्णु की दिव्यता और अधिकार क्षमता के लिए यह सबसे सही प्रतीक है।

मां लक्ष्मी और उल्लू

मां लक्ष्मी के वाहन उल्लू को सबसे अजीब चयन माना जाता है। कहा जाता है कि उल्लू ठीक से देख नहीं पाता, लेकिन ऐसा सिर्फ दिन के समय होता है। उल्लू शुभता और धन-संपत्ति के प्रतीक होते हैं।

    Dear all,

    I have benfield unit in my plant to remove CO2 from hydrocarbon gas from offshore. Recently, the unit has been experiencing foaming and we are yet unsure of the reason.

    The unit has one side stream mechanical filter to remove particulates (spec:10 microns) and has been clogging and needs to be replaced frequently lately which caused wonder among the engineers due to low total suspended solid (below 30ppm) in the system based on lab analysis. We dont have activated carbon installed yet.

    Here are my questions.

    1) Can the clogging be caused by other than solid particulates i.e antifoam (we use Unicorn) which we quite frequently injected in the system nowdays.

    2)what are good analysis to determine if there is heavy hydrocarbon trapped in the system that may cause foaming?( currently we are using Total organic Compound(TOC) & oil and grease)

    3)Can corrosion inhibitor from offshore caused foaming?

    4)Can anyone share any good laboratory that can analyze benfield composition in order to nail the culprit of the foaming.

    Thanks in advance

        Hello Hazree
        One point to watch out for with regard to using anti-foam. Apparently if one adds too much, or perhaps if it builds up in a system, it can have the opposite effect intended and cause foaming.

                Hi Hazree,

                Here are some of my thoughts :-

                A high concentration of anti-corrosive additive which is a surfactant may cause the foaming. The problem may be exacerbated by having a packed tower which has too many internals. One question is which of the columns is foaming or are they both foaming.

                One thing to note is that if you cooled the system without purging the CO2 then you would get a carbonate precipitate which would require heating and high recirculation to redissolve. If your internals are clogged, then of course you would get higher than design velocities of liquid through the tower. Have you measured your total carbonates ?

                I hope this helped.

                Best regards

                    You asked about how to know how much anti-foam is too much. This will depend on the chemical and the system it is added to. It would be best to discuss this with your antifoam supplier company. The supplier should be able to tell you all about using of their chemical. You may even have an employee internal to your comany that is managing the dosing chemical vendors.

                        Only the absorber is foaming.

                        if I my understanding is correct, clogegd internal may excerbate foaming although foam height is within acceptable level. In our case the foam height clearly shows beyond acceptable level which I think may indicate contaminant like dissolved hydrocarbon or something else.

                        The solution is not being cooled, so carbonate precipitation is minimal plus we have mechanical filter to remove particulates.

                            Dear all

                            Good day!

                            I would recommend to at least share your PFD , current operating data so that our friends can access the actual issue.
                            As DEA in Benfield is the degradable component, accordingly any degradation may result in excessive foam as DEA may polymerize with the passage of time

                            In view of your situation I would recommend the following

                            • Visually check color of the solution , if it is black and opaque it is clear indication of degradation of DEA
                            • Also analyze formation of Potassium formate
                            • Do check V+ and V+5 ions regularly. Often there is a rapid reduction of valence state of the corrosion inhibitor (vanadium) from the active V+5 to passive V+4 material is also observed
                            • Check over dosing of KNO2 used as oxidant
                            At the end please do consider installation of activated carbon filter as this will help is removing degradation product
                            and avoid excessive foaming and however, please do consult UOP while doing so as I have seen a failure of Benfield absorber due to wrong location of sample collection resulting wrong determination of v+5 state as the side stream passsing carbon filter can regain the v5 state

                            Best regards

                                Hi Hazree,
                                This is very common and interesting in CO2 removal units. From your descriptions, I would like to list down following root causes for foaming and recommend some actions. The best decision will be to contact experts if you do not have in house resorces and skills.
                                Probable causes:
                                1. Condensation of HC ( like CH4) below 45 C which causes foaming.
                                2. Degradation of DEA into HSS ( Heat Stable Salts) which will foam, corrode and plug your equipments in the system; activated carbon bed can not remove these ionised particles.
                                3.Excessive dosing of antifoam ( normal rate should be 50-100 ml per shift).
                                4. Presence of oxygenated compound ( like Corrosion inhibitors) adding feed to DEA to degrade into HSS.

                                1. Make a thorough analysis of your sample; contact MRP ( Netherlands),M.Coro/ M Tomasy from GV ,Italy for free analysis and troubleshooting .
                                2. Optimise CO2 scrubber inlet temperature to avoid HC condensation
                                3. Isolate filter when you are injecting antifoam ( I gues you blend thoroughly the antifoam with water before injecting). Inject antifoam based on foaming tendency ( foam test: Foam height and foam collapse time) and other operational symptoms like fluctuation of levels, temperature,DP etc.
                                4. Remove HSS by MPR or other company's suitable method or replace part of the solution with fresh make up.
                                5. Contact licensor or other experts who can help you.
                                Kind regards,

                                    Dear All

                                    Good Day!

                                    In my experience I have never heard of condensation of HC in Benfiled system. Also, to my knowledge there is not a single paper indicating such cause.Also, presence of HC , first of all indicated in the primary reformer, where presence of HC ( pentane and higher ) in natural gas results in carbon deposits in the tubes of primary reformer catalyst.Otherwise during normal operation with steam to carbon ratio of 3.0 , these HC are converted into hydrogen, Carbon dioxide and CO

                                    Presence of HC and operation at low S/C some times results in methanol formation and some ammonia in secondary reformer and HTS/MTS. This results is some foaming without deterioration in color index and can be controlled by increasing steam at the inlet of HTS/MTS

                                    Also, Absorber inlet temperature is normally in the range of 85 to 106 Deg C, which minimizes the chances of HC condensation / separation in absorber solution

                                    Regarding activated carbon filter it adsorbs organic polymers formed as a result of degradation of DEA and is a standard feature of new Ammonia plants with Benfiled system for CO2 removal and UOPL (Licenser of Benfiled Process recommended side stream filtration for removal of degradation product)

                                    We faced similar problem before we have activated carbon filter and after installation it is about 10-15 years of operation we are running with same solution with very small make up.

                                    Partial replacement of solution will result in smooth operation for 4-6 months as experienced by us and the situation then becomes similar as before. Due to the presence of vanadium, it is very difficult to dispose / discard Benfiled solution and it have to be taken in Benfiled storage tank which is meant to store Benfiled solution in the event the absorbation need to be drained .

                                    We Build new Benfiled tank to store the discared solution,

                                    Another solution is to use Benfiled ACT-1 but this effects the Benfiled water balance and need detailed evaluation by UOPL

                                        Dear All,

                                        Thanks for all the advise.

                                        here is an update.

                                        1) we are still seeing intermittent foaming in the system which we combat via antifoam injection.

                                        2) The total organic compound (TOC) analysis shows a figure in the 30,000 ppm which I think an indicative of heavy hydrocarbon presence in the system. So I think cannot eliminate this cause for foaming.

                                        3) Our total suspended solid reading is kept below 10 ppm which shows our mechanical filter is effective to remove this potential culprit.

                                        4)the formate analysis shows around 700 ppm of reading.

                                        There is also suggestion to keep delta T between inlet feed gas into absorber and potassium carbonate circulation into absorber between 5 to 8 degrees to avoid HC condensation. How credible is this advise?
