Abstract

Absorption extraction of C5+ hydrocarbons from formation gas of gas-condensate fields at the level of temperature of from –25 to –30°C was simulated. The following conditions were recommended during realization: absorbent by physical-chemical characteristics corresponding to hydrocarbons С910, four theoretical contact stages in the absorber, and partial expenditure of absorbent of 20–30 g/m3. Techniques of low-temperature absorption and low-temperature separation were compared. Parameters were determined that allow developing a scheme of a process with the increased degree of extraction of hydrocarbons С5+ (over 99%), which are valuable petrochemical materials.

Keywords:

gas-condensate fields low-temperature separation low-temperature absorption absorbent hydrocarbon fraction residual content of hydrocarbons С5+ in commercial gas degree of extraction
