FIELD: oil and gas industry.
SUBSTANCE: method of gas flow separation into single components or fractions involves implementation of a two-stage short-cycle heatless adsorption process in a stationary layer of the adsorbent. The initial gas flow is divided into N single components or fractions characterised by an affinity coefficient according to the adsorption affinity to the adsorbent, the least sorbed single component or fraction has an affinity coefficient a1=1, and the remaining sorbed single components or fractions have successively increasing affinity coefficients as the adsorption affinity of adsorbent increases aN>aN-1>…>a2>a1=1, sequentially directing it under high pressure to the adsorber desorber of adsorber N-1 unit and cleaning from the most sorbed components or single fractions.
EFFECT: invention solves the problem for development of effective method for separating the gas flow into single components or fractions based on the principle of short-cycle adsorption which provides energy and resource savings.
