A Brief Note On Gas Separation And Sequestration - 2801 Words

Dangling PEG Containing Thiol-ene Polymer Membranes Effect of Dangling PEG Moieties on CO2 Gas Selectivity, Gas Transport, and Free Volume Properties Tyler Haddock Graduate Student: Ramesh Ramakrishnan Advisor: Dr. Sergei Nazarenko Introduction Gas separation and sequestration is used in many of industrial processes. An emerging utilization is in fossil fuel plants, where fuel combustion waste is released.1 Among these products is CO2, which is why fuel plants and most notably coal plants—the number one producer of electricity in the United States—account for around 40% of all CO2 emissions.1-2 Carbon capture and sequestration (CCS) at fuel plants has duel benefits: an increase in the performance of fuels, such as natural gas from reduced CO2 concentration, and a lowering of the emission of a greenhouse gas into the atmosphere.1 Methods to separate and remove CO2 before being released as flue gas have already been implemented to a limited extent.1, 3 Separation of CO2 can occur before or after energy conversion, but pre-combustion treatments—such as gasification and oxy-combustion—also require the separation of H2 and O2 ¬ gases, respectively.1 Regardless of when the CCS stage occu rs, CO2 capture is the most costly step with common approaches including chemical absorption, surface adsorption, and membrane technology. The most developed and commonly used technique is absorption, often using amines such as monoethanolamine (MEA).1 MEA is effective due toShow MoreRelatedSocm Study Guide Essay30404 Words   |  122 Pages This infestation is the result of direct contact with the lice through sexual activity, toilet seats, clothing, or bedding.

White Privilege And Black Privilege - 2557 Words

White Privilege in America Privilege affects everyone, regardless of if they are affected positively or negatively. Being the majority of majorities in America, white males bear an automatic stamp of privilege on their foreheads, although they would care very strongly not to admit it. On the surface, privilege does not seem like such a bad thing, but when you pay attention to the differentiation of struggles between white men and everyone else in America, you can see it is a very large issue. Whether it is in the classroom, in the workforce, in real estate, or even in your own home, white privilege is affecting you. White male privilege in America is counterproductive to the growth of equality in society today because it affects the quality of living and level of opportunity for the rest of the country’s inhabitants. Within all facets of life, you can find extreme examples of white privilege. Ask yourself, if a policeman pulled you over, would you assume automatically that the crime was the color of your skin? And would you wonder if that crime could cost you your life? The unanimous answer should be no, but it is guaranteed that within different races and communities, the answer will differ. Because of this, it is clear that different people of different races get treated differently; some may view this as having cultural luxuries. What are cultural luxuries? Many people may wonder what that is and when it will be so kindly afforded to them.

Coal Mines in India

Question: Discuss about theCoal Mines in India. Answer: Introduction The question the essay will try to address is how can the government do to relieve the environmental issue caused by coal mining in India? This is by regulating the mining industry through proper rules and measures to take care of the environment since it has already become a danger zone. The coal mines are causing huge environmental issues in India. Some of the issues it has caused are air pollution, contamination of the ground water, and the wildlife being affected by the coal mines (Saini, Gupta Arora, 2016). Based on the claim by the World Health organization in 2008, coal particulates pollutions are generally anticipated to lessen to an approximation of one million lives globally (Arora, 2014). The India government can help solve these problems by provision of proper rules, which measures to take care of the environment because it is already in the danger zone (Riazi Gupta, 2015). The environmental legislation in India has been long standing in nature especially in the impleme ntation at the state level due to political issues over the years, but this has improved enormously over time and if the government help to implement appropriate measures and regulation, the sector could improve to a great deal (Chadwick, Highton Lindman, 2013). The Coal mines are causing huge environmental issues in India, some of these issues are air pollution, ground water contamination and impact to the wildlife. These are devastating issues especially to the economy of the country, and the well-being of individuals who are living next to those mines. Coal Mines are Causing Serious Effect on Air Pollution Based to the research done by Arora (2014), she has highlighted that coal mines has caused a lot of Air emission in India over the years. The waste products such as the fly ash , and boiler stag generates approximately twenty percent of toxic chemical which include mercury , cadmium , copper , beryllium as well as arsenic which are hazardous is these are released into the environment . These types of substances usually are impurities whenever coal continues to be burnt they are released (Chadwick, Highton Lindman, 2013). Throughout the process of combustion, the reaction, which is available between the coal and air it generates oxides of carbon including the carbon dioxide, which is a greenhouse gas, oxides of the sulphur and nitrogen of oxides (Kowalska, 2014). Whenever sulphur oxides and nitrogen oxide react in ambiance so that you can form particles and a ground ozone level that are delivered for long distances, rendering it hard it very hard for other of the states to attain a h ealthy levels of control of the pollution (Riazi Gupta, 2015). The high levels of the suspended particles could increase the respiratory ailments for instance the chronic bronchitis or maybe asthma whilst the gaseous emissions might lead to the worldwide warming apart from them leading to the well-being hazards to the population that has been exposed. Air Pollution Control Measure From the research from different authors I have come to understand air pollution control measure refers to the planning as well as implementation of a series of preventive measures which to enable the levels of pollution are maintained with a given level (Kowalska, 2014). Some of the measure to control air pollution are emission standard and the air quality management. The air quality management entails regulation of the location, time and the amount of the pollutant emission to achieve defined set of air quality standards (Singh, Singh, Singh, Chandra Shukla, 2007). The quality standards involves the control of the pollutant emission in order to ensure that the level does not exceed the limit that is accepted. The emission standards is usually distinguished for the specific group of the emitters (Pandey, Mohalik, Mishra, Khalkho, Kumar Singh, 2015). The emission standard is usually derived from consideration of the quality standards, which becomes the emission strategy. These appr oaches might help to reduce the level of air pollution to a significant level. Other measures that India government could use is the economic based method through providing financial incentives for the emission sources to pursue the most cost effective means to reduce pollution. The firms should be urged to find new methods and new products that provide lower level of pollution. Ground Water is Contaminated by Coal Mining It has been known that the ground water is becoming the primary concern with respect to the surface mining of coal in India. The major concern has been the quality and the quantity of the ground water (Pandey, Mohalik, Mishra, Khalkho, Kumar Singh, 2015). The ground water pollution usually occurs either directly or indirectly because of the surface mining. Direct degradation might happen in the event that the ground water continues to be located down gradient from the surface mine by the flow of the polluted drainage from the coal mine (Mukhopadhyay, Masto, Cerd Ram, 2016). The ground water pollution could result from the coal materials, which causes the surface water contamination. The indirect degradation of the ground water might results from the blasting that may cause the shaking of the rocks temporary in the fractures near the working areas of mines. The ground water contamination may also results from various chemistry from the polluted surface level before the treatment of the chemicals. Solution to Ground water contamination by coal mines Several actions can be taken to lessen on the chances of the ground water pollution from occurring because of the issue of surface mining (Mukhopadhyay, Masto, Cerd Ram, 2016). The ground water in India should be directed away from the mine sites both during as well as after mining. In the event that the ground water pollution has been detected, one of the first issue is to locate and stop the discharge from the specific pollution sources on the sites of the mine. Additionally, there should be installation of the impermeable barrier in the backfill to the streams channel that are nearby. Coal mines are affecting wild life The wildlife animals we all know they are great significant to a countries economy and the government should put measures to keep them away from any danger. The surface mining of coal in India causes a direct as well as indirect damage to the wildlife. It affects the wildlife primarily from the disturbance, removing as well as redistributing the land surface (Martinez-Alier, Temper Demaria, 2016). The immediate impact on the wildlife is fundamentally from the destruction or maybe the displacement of the species particularly in the regions of excavation along with spoil piling. The primary affect of the surface exploration is degradation. The impact of the sediment on the aquatic wildlife differs with the species and amount of the contamination. In the event there exists high sediment amounts, it may kill fish directly, reduce light transmission as well as alter the gradient temperature. How wildlife can be saved from coal mines I think the solution this situation is to abandon the mines that are in the habitat of the wild life. The mined areas should be backfilled and then rehabilitated for the purpose of the development of vegetation (Vinoth Kumar, 2014). The void that is formed by the open pit of mining usually causes land degradation it could be utilized to serve as the reservoir for water thus providing moistures for the vegetation in the surrounding areas. Conclusion There should be proper rules as well as measures in order to take care of environment that is in the danger zone. More and more companies in India should be encouraged to adopt on the best practices and technologies, which are healthy to the environment, and ensures the safety of the miners. The future direction that should be followed is as follows: they should adopt environmentally friendly technologies, and resource conservation as well as management through minimal waste in the extraction of coal, and perhaps find substitute of the minerals that could be used to extract energy. Another angle is through effective environmental regulation as well as safety and health inspection of mines should be in place. The government could bring out some guidelines mining companies could use. Lastly, it could be through development of environmental indicators in order to assist in the assessment of the state of the environment in the areas of mining. References Arora, N. (2014).

One has to imagine the sounds in a poem when it is being read silently. Task : Try reading these lines silently and then orally. Out Written He drew a circle that shut me out- Heretic, rebel, a thing to flout, But Love and I had wit to win: We drew a circle that took him in. (Edwin Markham) The sounds in the poem give it much of its beauty. Task : Read the poem above again, this time with everyone reading together at a time. This is called choral reading. Doing things together is fun. This is one reason why girls and boys big and small love choral reading. They derive much fun when they read well together, when they read as one person. Choral reading is a delightful way to help children interpret and share prose and poetry. Before the class actually starts reading a selection together, they must think about its meaning and how they can use their voice as an artist’s tool. They must think about the rhythm and sound of each line or sentence†¦. noting which words they need to stress and where pauses most naturally fall. This type of reading helps the class to enunciate clearly and to vary the volume, tempo, and quality of their voices for special effects. Choral reading is rewarding in many ways. Not only is it a creative and enjoyable activity, but it helps them learn to plan and work together. Students who are shy tend to lose thirir shyness and speak out in the safety of the group. They learn the importance of co-operation as they take turns to blend their voices in group response. Types of Choral Reading : 1. Refrain 2. Line-a-child 3. Antiponal 4. Unison Refrain : This type of reading is natural for a poem that contains a refrain. Usually the whole group says the refrain and one person speaks the other lines or the group can speak the lines, and one or two people the refrain. Line–a–child : In this type of reading, a number of lines are read in solo manner, each by a different child. Chosen parts of the poem are spoken by the group in unison. Each child having a solo part must watch his cue, as in dramatics, so as to speak his line promptly when his turn comes. This type works well with poems which have three or more characters. Antiphonal : This type of reading brings light and heavy voices into play against each other. It dramatizes a poem that contains dialogues, questions and answers. Or other elements giving contrasts. From the nature of the poem the class can decide which lines should be spoken by heavy voices and which by light. Unison : This is actually the most difficult type of choral reading. It requires students to stay together for a longer period of time. One can have this type of recitation for poems which have little change of moods and no dialogue. It tries to blend all kinds of voices in a suitable rhythm, volume, and tone. It is best to use this type of reading for a class that has little experience in choral reading. Poems for practice : Scythe song All:Mowers, weary and brown and blithe, What is the song methinks ye know. Endless over-work that the Scythe Sings to the blades of grass below? Scythes that swings in the grass and clover, Something, still, they say as they pass; What is the work that, over and over, Sings the Scythe to the flowers and grass? Girls:Hush, ah hush, Boys:the Scythes are saying Girls:Hush, and heed not, and fall asleep! Hush, Boys:They say to the grasses swaying, Girls:Hush, Boys:They sing to the clover deep! Girls:Hush- Boys:‘tis the lullaby Time is singing- Girls:Hush, and heed not, for all things pass, Hush, ah hush! Boys:and the scythes are swinging All:Over the clove, over the grass! OPPORTUNITY Solo:This I beheld, or dreamed it in a dream: Girls:There spread a cloud o fdust along a plain And beneath the cloud, or in it, Boys: raged A furious battle, and men yelled, and swords Shocked upon swords and shields. A prince’s banner Wavered, then staggered backward, hemmed by foes. Solo:A craven hung along the battle’s edge, And thought, Girls: â€Å"Had I a sword of keener steel- That blue blade that the king’s son bears, -but this Blunt thing -! † Solo: He snapt and flung it from his Hand, And lowering crept away and left the field. Boys:Then came the king’s son, wounded, sorre bestead, And weaponless, and saw the broken sword, Hilt-buried in the dry and trodden sand, All:And ran and snatched it, and with battle shout Lifted afresh, he hewed his enemy down, And saved a great cause that heroic day.
