Abstract:
Provided is a method for producing a hydrogen chloride that is capable of efficiently producing a hydrogen chloride with a simple facility. The hydrogen chloride is produced by a method including causing an inert gas to be in gas-liquid contact with a hydrochloric acid in which a concentration is 20 mass % to 50 mass %, distilling the hydrochloric acid with which the inert gas is in gas-liquid contact in the gas-liquid contact and separating a hydrogen chloride from the hydrochloric acid to obtain a crude hydrogen chloride, dehydrating the crude hydrogen chloride obtained in the separating, and compressing and liquefying the dehydrated crude hydrogen chloride obtained in the dehydrating, and purifying the liquid crude hydrogen chloride by distillation.

Claim (Index 2):
The method for producing a hydrogen chloride according to  claim 1 , wherein in the gas-liquid contact, the inert gas comes in gas-liquid contact with the hydrochloric acid, by causing the inert gas to be in contact with the hydrochloric acid of a flow rate in which a linear velocity is 0.1 m/h to 15 m/h and a space velocity is 0.1/h to 10/h in a counter-current flow manner, and a ratio of a volume flow rate of the inert gas to a volume flow rate of the hydrochloric acid is 0.01 to 100.
