Co2 desorption without stripper

Abstract

A CO 2 desorption method and equipment for performing this method is described. More specific, a method for desorbing CO 2 from an absorption fluid without involving a traditional stripper but instead using a heat exchanger as a flash-tank is disclosed. Further described is the utilization of cooling heat from a condenser for cooling the lean absorbent fluid.

What is claimed is: 
     
         1 . A system for desorbing carbon dioxide from a CO 2  rich absorption fluid, the system comprising a flash-tank with an inlet, a vapour outlet and liquid outlet, where the vapour outlet is in fluid communication with an inlet to a condenser, where the condenser has a condensed fluid outlet in fluid communication with the liquid outlet from the flash-tank. 
     
     
         2 . A system according to  claim 1 , wherein the system further includes a system for supplying heat to the flash-tank. 
     
     
         3 . A system according to  claim 1 , wherein the flash-tank is a reboiler, a stratified flow pipe, or a fired heater combined with a vessel. 
     
     
         4 . A system according to  claim 1 , wherein the system further comprises a recycling pipeline in fluid communication with the liquid outlet and an inlet to the flash tank, arranged up-stream the fluid communication between the condensed fluid outlet and the liquid outlet.
