If the acid gas content of the sweetened gas exceeds sales specifications, the following areas should be investigated:
*insufficient amine circulation rate:
:-operating problems with the train’s online charge amine pump
:-speed of online charge amine pumps too low
:-amine booster pump operating problems
:-low level in the amine surge tank
*insufficient amine regeneration:
:-insufficient stripping steam/reboiler heat input
:-insufficient amine still reflux
:-incorrect amine still pressure
:-contaminated or degraded amine
:-plugged amine still valve trays
:-too low a amine flow through Amine regenerator
:-internal leakage problems at lean/rich amine exchangers causing rich amine to leak into lean amine
*different operating conditions:
:-lean amine too hot
:-amine contactor pressure too low
:-too high a gas flow through contactor
:-amine concentration too high or too low
:-too high a gas flow through contactor
