The separation process of methane-butane fraction from natural gas before transport

Abstract

A series of experiments of adsorption of vapor-air mixtures of some individual hydrocarbons on fibrous sorbents out of polyethylene and polypropylene is made. The calculated changes of concentrations of hydrocarbons in the vapor-air mixture base on experimental data. It is shown that concentration of hydrocarbons decreases after column by 1.4 times and that sorption capacity of fibers reaches 1 g of hydrocarbons on 1 g of a fibrous sorbent. This result was assumed as a basis of calculation of model of the separator for separation of hydrocarbons С[1-4] from water and fractions С[5-n], the degree of separation of the first stage gas of the Verkhne - Tarskoe's field was 98 %.
