Natural Gas Separation
Summary
Gas separation plant consists of typical processes such as gas inlet receiving, dehydration & mercury removal, NGL recovery, NGL fractionation, etc. to separate methane, ethane, propane, butane and C5+ from natural gas as feed gas.
Features
Feedstock & Products
The feedstock of gas separation plant is natural gas through pipeline from onshore or offshore. The natural gas composition at the inlet of gas separation plant is typically hydrocarbons, which is distributed from C1 (methane) to around C10 (decane), nitrogen, carbon dioxide, water and sulfur components such as H2S, COS and mercaptan.
The products of gas separation plant are typically methane, ethane, propane, butane and C5+ and alternatively LPG (liquefied petroleum gas) would be products instead of propane and butane.
Utilization of Gas Plant Products
Methane is one of energy sources of power plants and cities via pipelines. Ethane, propane and butane are one of feedstocks of petrochemical plants in the downstream of gas separation plant to produce ethylene and propylene. C5+, which C5 and heavier are included, is one of the feedstocks of refinery plants to blend into gasoline as well as petrochemical plants.
