Acid gas removal system for removing acidic gases from gaseous hydrocarbons

An acid gas removal system for removing acidic gases from gaseous hydrocarbons, the system comprising:

• an absorption liquid solvent capable of removing acidic gases from gaseous hydrocarbons;
• a contactor having:
• a gas inlet adapted for receiving a stream of the gaseous hydrocarbons containing the gaseous hydrocarbons;
• a gas outlet adapted for providing an outlet for the gaseous hydrocarbons after removal of the acidic gases therefrom, the gaseous hydrocarbons being contacted by the absorption liquid solvent and the acidic gases being removed therefrom by absorption into the absorption liquid solvent inside the contactor;
• an absorption liquid inlet for introducing the absorption liquid solvent into the contactor;
• and
• an absorption liquid outlet for removing used absorption liquid solvent having the acidic gases absorbed therein from the contactor;
• a stripper for stripping the acidic gases from the used absorption liquid solvent and recovering recycled absorption liquid solvent from the used absorption liquid solvent;
• a first heat exchanger in fluid communication with the contactor, the first heat exchanger being configured for receiving the used absorption liquid solvent, for heating the used absorption liquid solvent by heat exchange with a hot fluid to form a heated solvent, and for outputting the heated solvent to the stripper for removal of the acidic gases therefrom;
• a second heat exchanger in fluid communication with the stripper, the second heat exchanger being configured for receiving the recycled absorption liquid solvent, for cooling the recycled absorption liquid solvent by heat exchange with a cold fluid, and for outputting the recycled absorption liquid solvent to the absorption liquid inlet of the contactor;
• and
• a reverse pump in fluid communication with the contactor, the reverse pump being connected for removing hot fluids from the contactor, for heating water from an external source to produce a first stream of steam by heat exchange with the hot fluids, and for returning the hot fluids to the contactor after heat exchange.
