FIELD: performing operations.
SUBSTANCE: invention relates to adsorption purification of natural gas and can be used at gas industry enterprises. Claimed method for adsorption purification of natural gas of high pressure, including an adsorption unit consisting of N adsorbers operating alternately, a heat exchanger-heater, a condenser-cooler, a settling tank, pipeline valves (control and shutoff valves) and a throttle, which are connected by a system of pipelines, enables to obtain a number of technical results: increase the efficiency of using the adsorbent by increasing the proportion of the adsorbent, which provides for the purification of natural gas during the operating cycle of the plant, from the total load of the adsorbent to plant from 66.6% to 100% when performing procedure (f), eliminating risks of emergency situation due to failure of shutoff valves and reducing risks of poor-quality regeneration of adsorbent or its cooling due to variability of using backup procedure (d).
EFFECT: increased efficiency of adsorbent use and reduced risks of emergency situation occurrence due to failure of shut-off valves.
