Removal of Contaminants from Natural Gas essays

Removal of Contaminants from Natural Gas essays Natural gas is one of the most popular forms of energy today. It is a colorless, odorless fossil fuel that is environmentally friendly relative to other fuel sources. Methane is the major component of natural gas, which is used in heating, cooling, production of electricity, and many other uses such as the reforming process to manufacture fertilizer. Natural gas is found by drilling into the earth's crust where pockets were trapped thousands of years ago. Once the gas is brought to the surface, it must be processed to remove impurities such as liquids (water, heavier hydrocarbons), sand, other gasses like carbon dioxide, hydrogen sulfide, butane, propane, ethane, etc. The removal of these impurities occurs in what is known as the Gas Processing Industry using various techniques to produce what we know as Natural Gas. The final product is transported throughout the country using large pipelines to large industry, small businesses, and residential customers. Initial Stages – Physical Separation The natural gas processing industry begins with the separation of the bulk liquids from the gas streams. While the devices that perform these tasks can get complicated they all work on basic principles. Generally, the industry refers to these devices as either "separators or scrubbers" and they are simply large vessels that are designed to slow the fluid velocity and allow gravity to cause liquid droplets to fall. In addition these vessels provide enough space to allow the gas to separate from the liquid and a means for the gas stream and liquid streams to exit separately. Often they are built to separate three phases, two liquid (water & hydrocarbons) and gas by using a boot on the bottom or and intermediate exit point created using a pipe extension or side exit point. At the gas outlet, most of these devices use a mist eliminator to remove small fine droplets. Most mist eliminators look similar to a block of steel wool and provide a s...

MLA Referencing †Citing an Edited Book (Proofread My Paper)

MLA Referencing – Citing an Edited Book MLA Referencing – Citing an Edited Book MLA referencing offers a simple way of citing sources in a college paper. However, for an edited book, there are some rules you need to remember, especially on the â€Å"† page. First, though, let’s take a quick look at citing sources in the text. In-Text Citations When citing something from an edited book in MLA, give the surname of the author of the section cited and the relevant page number(s) in parentheses: Communication can influence an individual’s expectations (Smith 253). As with other source types, you do not need to repeat the name of the author in citations when they’re already named in the text: According to Smith, communication is â€Å"one of the means by which an individual can influence another individual’s expectations† (253). The only time you’ll need to cite the editor or editors is when citing an edited volume as a whole, but this would be unusual most of the time. The Page (Chapter from an Edited Book) MLA requires that all sources cited are listed in a â€Å"† page at the end of your document. When citing a single chapter from an edited book, the format to use is: Author Surname, Forename. â€Å"Chapter Title.† Edited Book Title, edited by Editor’s Name, Publisher, Year, Page Range. As such, the essay used in the examples above would appear as: Smith, John W. â€Å"Communication and Expectations: A Social Process and the Cognitive Operations It Depends Upon and Influences.† Readings in Animal Cognition, edited by Mark Bekoff and Dale Jamieson, MIT Press, 1996, pp. 243-55. The Page (Multiple Chapters) This format differs slightly if you’re citing several chapters from the same edited book, as MLA referencing allows you to cross-reference entries to save repeating information. This involves first adding a separate entry in the â€Å"† list for the volume as a whole: Editor Surname, Forename, editor(s). Title of Book. Publisher, Year of Publication. If a book has multiple editors, you only need to invert the names of the first author. We would therefore list Readings in Animal Cognition as: Bekoff, Mark and Dale Jamieson, editors. Readings in Animal Cognition. MIT Press, 1996. After this, each essay from the edited volume can be listed separately, mentioning the editor(s) of the edited book and page range to show where they come from: Bekoff, Mark and Dale Jamieson, editors. Readings in Animal Cognition. MIT Press, 1996. Gruen, Lori. â€Å"Gendered Knowledge? Examining Influences on Scientific and Ethological Inquiries.† Bekoff and Jamieson, pp. 17-27. Smith, John W. â€Å"Communication and Expectations: A Social Process and the Cognitive Operations It Depends Upon and Influences.† Bekoff and Jamieson, pp. 243-55. Thornhill, Randy. â€Å"The Study of Adaptation.† Bekoff and Jamieson, pp. 107-27. Finally, remember to maintain alphabetical order by surname throughout your â€Å"† page. This order must be used even if it means that chapters from an edited book aren’t listed together.
