Abstract
A system (100) for regenerating an absorbent solution, including: steam (128) produced by a boiler (130); a set of pressure turbines (132) fluidly coupled to the boiler; a siphoning mechanism (134) for siphoning at least a portion of the steam produced by the boiler; and a regenerating system (118) fluidly coupled to the siphoning mechanism, wherein siphoned steam is utilized as a heat source for the regenerating system.
Claims23
A process for providing at least a portion of steam produced by a boiler to a regenerating system, said process comprising:
- producing a steam by combusting a fuel source in a boiler;
- providing at least a portion of said steam to a set of pressure turbines fluidly coupled to said boiler, said set of pressure turbines including a high pressure turbine, an intermediate pressure turbine, and a low pressure turbine;
- siphoning at least a portion of said steam provided to said set of pressure turbines through a siphoning mechanism to produce siphoned steam, wherein said siphoning mechanism is located at a position selected from a group consisting of a position between said boiler and said high pressure turbine, a position between said high pressure turbine and said intermediate pressure turbine, a position between said intermediate pressure turbine and said low pressure turbine, and combinations thereof;
- and
- utilizing said siphoned steam as a heat source for a regenerating system fluidly coupled to said siphoning mechanism.
A system for regenerating an absorbent solution, said system comprising:
- steam produced by a boiler;
- a set of pressure turbines fluidly coupled to said boiler, said set of pressure turbines including a high pressure turbine, an intermediate pressure turbine, and a low pressure turbine;
- a siphoning mechanism for siphoning at least a portion of said steam produced by said boiler, wherein said siphoning mechanism is located at a position selected from a group consisting of a position between said boiler and said high pressure turbine, a position between said high pressure turbine and said intermediate pressure turbine, a position between said intermediate pressure turbine and said low pressure turbine, and combinations thereof;
- and
- a regenerating system fluidly coupled to said siphoning mechanism, wherein siphoned steam is utilized as a heat source for said regenerating system.
In a system for regenerating an absorbent solution, the system comprising a first boiler generating a process stream and steam, an absorber for removing an acidic component from said process stream thereby forming a rich absorbent solution and a cleansed process stream, and a regenerator for regenerating said rich absorbent solution, the improvement comprising:
- a second boiler generating steam;
- and
- a reboiler coupled to said regenerator, wherein at least a portion of steam from said second boiler is provided to said reboiler.
