The process for preparation of hydrochloric acid consists in burning of hydrogen in chlorine, cooling of forming gas and absorption of chlorine hydride by water. The absorption of chlorine hydride is carried out in two stages. On the first stage from 2 till 12.4 % of chlorine hydride is absorbed by means of supply of water or hydrochloric acid to the absorber with mass fraction of HCl to 18 % in quantity from 0.05 to 0.25 dm3/m3 of gas. In addition the initial linear velocity of gas is maintained from 0.5 to3.0 m/s. On the second stage the rest quantity of chlorine hydride is absorbed with obtaining of base product.
