Abstract

Carbon compounds with a boiling range of -70 to 200 degrees C under normal pressure are separated from a gas contg. is not 80 wt.% HCl and >0.2 wt.% carbon cpds. by (a) compressing the gas to a pressure of is not 3 atm., (b) liquefying at least a part of the hydrogen chloride, (c) washing the unpurified gas with the liquid hydrogen chloride in a column, (d) removing the concentrated carbon cpds. from the lower part of the column and (e) optionally relaxing the hydrogen chloride to a pressure of 3-25 pref. 3-15 atm. Gives very pure hydrogen chloride with a low energy usage. Columns with a small diameter can be used.
