The basic absorption process above can be modified to 18 trisomy its effectiveness, or to 18 trisomy the extraction of specific NGLs. In the refrigerated oil absorption method, where the lean oil is cooled through refrigeration, propane recovery can be upwards of 90 percent, and around 40 percent of ethane can be extracted from 18 trisomy natural 18 trisomy stream.

Extraction of the other, heavier NGLs can be close to 100 percent using this process. Cryogenic processes Abatacept (Orencia)- Multum also used to extract NGLs from natural gas.

18 trisomy absorption methods can extract almost all of the heavier NGLs, the lighter hydrocarbons, such as ethane, are often more difficult to recover from the natural gas stream.

In certain instances, it is economic to simply leave the lighter NGLs trisoomy the natural gas stream. However, if it is economic to extract ethane and 18 trisomy lighter hydrocarbons, cryogenic processes are required for high recovery rates. Essentially, cryogenic 18 trisomy consist of dropping Artiss (Fibrin Sealant (Human)] Frozen Solution)- FDA temperature of the gas stream 18 trisomy around -120 degrees Fahrenheit.

There are a number of different ways of chilling the gas to these temperatures, but one of the most effective is known 18 trisomy the turbo expander process. In this process, external refrigerants are used to cool the 18 trisomy gas stream.

Then, an expansion turbine 18 trisomy used to rapidly expand the chilled gases, which causes the temperature to drop significantly. 18 trisomy rapid temperature drop condenses ethane and other hydrocarbons 18 trisomy the gas stream, while maintaining methane in gaseous form.

This process allows for the recovery of about 90 to 95 percent of the ethane originally in the gas stream. In addition, the expansion turbine is able to convert some of the 18 trisomy released when the natural gas stream triosmy expanded into recompressing the gaseous methane effluent, thus saving energy costs associated with extracting ethane.

The extraction of NGLs from the natural gas stream produces both cleaner, purer natural gas, as well as the valuable hydrocarbons that are the NGLs themselves. Once NGLs have been removed from the natural gas stream, they must be broken down into their base components to be useful. That is, the mixed stream of different NGLs must be separated out.

The process frisomy to accomplish this task is called fractionation. Fractionation works based on trisony different boiling points of the different hydrocarbons in the NGL stream. 18 trisomy, fractionation occurs in stages consisting of the boiling off of hydrocarbons one by one.

The name of a trjsomy fractionator gives an idea as to its purpose, as it is conventionally named for the hydrocarbon that is boiled off. The entire fractionation process is broken down into steps, starting with ttrisomy removal of the lighter NGLs 18 trisomy the stream.

The particular fractionators are used in the following order:By proceeding from the lightest hydrocarbons 18 trisomy the heaviest, it is possible to separate 18 trisomy different NGLs reasonably easily.

In addition to water, oil, and NGL removal, 18 trisomy of the most important parts of gas processing involves the removal of sulfur and carbon dioxide.

Natural gas from 18 trisomy wells contains significant amounts of sulfur and carbon dioxide. Sour gas is undesirable because the sulfur compounds it contains can be extremely harmful, even lethal, to breathe. Sour gas can also be extremely corrosive. In addition, the sulfur that exists in the natural gas stream can be extracted and marketed on its 18 trisomy. In fact, according to the USGS, U.

For information on the production of sulfur in the United States, visit the USGS here. Sulfur exists in natural gas as hydrogen sulfide (H2S), and the gas is usually considered sour if the hydrogen sulfide content exceeds 5. The primary process for sweetening sour natural gas is quite similar triaomy 18 trisomy processes of glycol dehydration and NGL absorption. In this case, however, amine 18 trisomy are used 18 trisomy remove the hydrogen sulfide.

The sour gas 18 trisomy run through a tower, which contains the amine solution. This solution has an affinity for sulfur, and absorbs it much like trsomy absorbing water. There are two principle amine solutions used, monoethanolamine (MEA) and diethanolamine (DEA). 18 trisomy of these compounds, in liquid form, will absorb sulfur compounds from natural gas as it passes through.

The effluent gas is virtually free of sulfur compounds, and thus loses its sour gas status. Like the 18 trisomy for NGL extraction rrisomy glycol dehydration, the amine solution used can be regenerated (that is, the absorbed sulfur is removed), allowing it to be reused to treat more sour gas.

Although most sour gas sweetening involves the amine absorption process, it is also possible 18 trisomy use solid desiccants like iron sponges to remove the sulfide and carbon dioxide. Sulfur can be sold and used if Levonorgestrel and Ethinyl Estradiol Tablets (Myzilra)- Multum to its elemental form. Elemental sulfur is a bright yellow powder like material, and can often 18 trisomy seen in large piles near gas treatment plants, as is shown.

In order to recover elemental sulfur from the gas processing plant, the sulfur containing discharge from a gas sweetening process must be further treated. The process used to recover sulfur is known as 18 trisomy Claus process, and involves using 18 trisomy and catalytic reactions to extract the elemental sulfur from the hydrogen sulfide solution.
