Title: APPARATUSES AND METHODS FOR REMOVING ACID GAS FROM SOUR GAS
Abstract:
Embodiments of apparatuses and methods for removing acid gas from sour gas are provided. In one example, an apparatus comprises an absorption zone. The absorption zone is configured for contacting the sour gas with an absorbent solvent that is at a first predetermined temperature of less than 0° to remove the acid gas and form a treated gas stream that includes entrained absorbent solvent. A heat exchanger or heater is configured to heat the treated gas stream to a second predetermined temperature of greater than 0° to form a partially heated treated gas stream. A water wash zone is configured for contacting the partially heated treated gas stream with water to remove the entrained absorbent solvent and form a solvent-depleted treated gas stream.
