As a general rule, when at least 90% of the NGL stream has only one type of carbon molecule, this NGL, whether ethane or butane, is defined as a purity product. 12 Generic NGL fractionation process block diagram. NGL Realized pricing at the plant = Hub value - the Fractionation. Thus the lean oil, in completing a cycle, goes through a recovery stage where it recovers light and intermediate components from the gas, a rejection stage where the light ends are eliminated from the rich oil and a separation stage where the natural gas liquids are separated from the rich oil. 3 Description of a natural-gas processing plant. Each NGL has its own unique boiling point and by controlling the temperatures within the different chambers, each specific hydrocarbon can be systematically removed and collected. While butane and isobutane both have four carbon atoms, they differ somewhat in molecular structure. The plant produces ethane, propane, butane and heavier gases. The removal of natural gas liquids usually takes place in a relatively centralized processing plant, and uses techniques similar to those used to dehydrate natural gas. 8m in length. e. 0015.
