Natural gas condensate gases can be divided into two groups: associated petroleum gases (APG) and gases of gas condensate fields. These gases differ in the composition of hydrocarbon components. The processing of petroleum gases is mainly carried out at gas processing plants, where hydrocarbons (HC) C3+B are extracted as fully as possible. The main commercial products of APG processing are liquefied petroleum gas, dry distilled gas (methane-ethane), a wide fraction of light hydrocarbons (SHFLU) and gasoline fraction (C5+B). Absorption technologies have occupied a certain niche in the technological chain of APG processing. At the current technological level of development in factory conditions, they allow almost completely extracting HC C3+ B from the raw material stream.
