1. A system for regeneration of acidic gas solvent, the system comprising;
a flash drum arranged to receive a solvent laden with an acidic gas and generate a lean amine flow;
a lean rich heat exchanger, said lean amine flow arranged to pass through the lean rich exchanger;
a regeneration cell having a solvent chamber arranged to receive the lean amine flow from the lean rich heat exchanger, and an internal chamber arranged to receive a steam flow;
the regeneration cell including a gas permeable membrane separating the solvent chamber and internal chamber;
wherein the regeneration cell is arranged to vent acidic gas stripped from the lean amine flow by the steam.
