  • Low pressure steam pre-heaters for gas purification systems and processes of use
    Patent number: 8833081
    Abstract: Systems for regenerating an absorbent solution include steam produced by a boiler; a set of pressure turbines fluidly coupled to the boiler for receiving the steam, wherein the set of pressure turbines comprises a high pressure turbine, a medium pressure turbine and a low pressure turbine; and a regenerating system comprising a regenerator for regenerating a rich and/or semi-rich absorbent solution to form a lean absorbent solution in fluid communication with a reboiler, the regenerating system fluidly coupled to the set of pressure turbines, wherein steam from the low pressure turbine provides a heat source for preheating the rich or the semi-rich absorbent solution fed to the regenerator. Also disclosed are processes of use.

  • Low pressure stripping in a gas purification process and systems thereof
    Patent number: 8690992
    Abstract: Processes for operating an ammonia stripper at a low pressure in a gas purification system include providing a first side-draw stream from the ammonia stripper; heating the first side-draw stream with a second side-draw stream from a regenerator; providing a stripper offgas stream from the ammonia stripper to a stripper overhead condenser; and utilizing the stripper offgas stream as a heat source for a regenerating system fluidly coupled to the stripper overhead condenser. Also disclosed are systems for implementing the processes.
