Hydrogen chloride recovery |
| abstract |
Process for recovering hydrogen chloride from a gas withdrawn from an oxychlorination reaction zone which contains hydrogen chloride and water vapor wherein the gas is initially cooled, followed by contacting the gas with a small amount of water to absorb the hydrogen chloride from the gas. The water content is controlled to provide an aqueous hydrogen chloride stream having a hydrogen chloride concentration of from 10% to 20%, with the absorbed aqueous hydrogen chloride being recycled to the oxychlorination reaction. A dilute aqueous hydrogen chloride stream, obtained from another portion of the process, may be employed in the initial cooling step, as a direct quench, resulting in vaporization of the dilute aqueous hydrogen chloride stream and eliminating the necessity for a hydrogen chloride concentrator. |
