Absorption techniques for field preparation of gas-condensate gases
Some field absorption procedures for preparation of natural gas-condensate gases, including both oil absorption regarding associated oil gases and low-temperature absorption regarding gas-condensate gases, are examined. Application of 1st-stage-separation condensates and separate fractions of hydrocarbons as the absorbents is analyzed. There are some results of laboratory and industrial tests of bifunctional absorbents, such as a mixture of diethylene glycol and monoethyl ester of triethylene glycol, N-methylpyrrolidone and a mixture of diethylene glycol with solar oil. Ways for further perfection of field absorption low-temperature techniques are targeted.
