Patent ID: 7827776

Claim:
A power generation system, comprising: a gas turbine for generating power; a gasifier for generating gaseous fuel; a gas combustor configured to receive a combination of steam and the fuel to power the gas turbine; a manifold section, including a manifold drain, configured to provide the combination of steam and the fuel to the gas combustor; and a drain collection and separation system configured to (i) collect a portion of the steam which has entered into the manifold as a condensed liquid and a portion of the gaseous fuel entrained in the liquid, and (ii) separate the entrained gaseous fuel from the liquid so the separated gaseous fuel can be cycled or disposed of separately from liquid, the drain collection and separation system including a liquid-gas separation tank and a drain line connecting the manifold drain to the liquid-gas separation tank so that the liquid-gas separation tank receives the condensed liquid with entrained gaseous fuel from the manifold, and wherein separation of the entrained gaseous fuel from the liquid occurs in the liquid-gas separation tank based on movement of the liquid along a wall of the tank.
