FIELD: gas industry; dehumidification of gas to be piped through considerable distances.
SUBSTANCE: proposed method consists in bringing the moist natural gas in contact with sulfuric acid of constant composition. Part of natural gas is directed to contact with sulfuric acid after which it is mixed with remaining part of natural gas. In the course of contact, concentration of sulfuric acid is maintained at level no less than 80% H2SO4 by continuous removal of part of acid from process and introduction of fresh acid whose concentration exceeds concentration of acid being removed. Removed sulfuric acid may be used in processes of handling low-concentration sulfuric acid.
EFFECT: enhanced reliability of gas dehumidification; low cost of process; simplified equipment.
