An apparatus for handling lock gas which enters a charging lockhopper (12) from a fixed bed coal gasifier vessel (10), after the charging of the gasifier vessel with coal, includes a separator (36) having a fluid inlet (38), a gas outlet (42) and a drain (44). After a charging operation, a pump (56) floods the lockhopper (12) with water under pressure to force the lock gas through the fluid inlet (38) to the separator (36) without loss of gas pressure. When rising water is sensed (at 48) in the separator, the pump (56) is deactivated and drain valves (30, 46) are opened to drain water from the separator and lockhopper back into a storage tank (52). The lock gas leaves the separator under pressure and may be applied to gas cleanup equipment. <IMAGE> |
