Gas Processing – Design Considerations

The design of any of the distillation processes discussed requires choosing an operating pressure, bottoms temperature, reflux condenser temperature and number of trays. This is normally done using any one of several commercially available process simulation programs which can perform … Continue reading

Gas Processing – Fractionation

The bottoms liquid from any gas plant may be sold as a mixed product. This is common for small, isolated plants where there is insufficient local demand. The mixed product is transported by truck, rail, barge or pipeline to a … Continue reading

Gas Processing – Cryogenic Plants

Figure 9-3 shows a typical cryogenic plant where the gas is cooled to -100°F to ~150°F by expansion through a turbine or Joule-Thompson (J-T) valve. In this example liquids are separated from the inlet gas at 100°F and 1,000 psig. … Continue reading

Gas Processing – Refrigeration

In a refrigeration plant the inlet gas is cooled to a low enough temperature to condense the desired fraction of LPG and NGL. Either freon or propane is used as the refrigerant. Figure 9-2 shows a typical refrigeration plant. The … Continue reading

Absorption/Lean Oil

The oldest kind of gas plants are absorption/lean oil plants, where a kerosene type oil is circulated through the plant as shown in Figure 9-1. The “lean oil” is used to absorb light hydrocarbon components from the gas. The light … Continue reading

Gas Processing

The term “gas processing” is used to refer to the removing of ethane, propane, butane, and heavier components from a gas stream. They may be fractionated and sold as “pure” components, or they may be combined and sold as a … Continue reading
