ABSTRACT:
An apparatus for handling lock gas which enters a charging lockhopper from a fixed bed coal gasifier vessel includes a separator having a fluid inlet, a gas outlet and a drain. After a charging operation, a pump floods the lockhopper with water under pressure to force the lock gas through the fluid inlet to the separator without loss of gas pressure. When rising water is sensed in the separator, the pump is deactivated and drain valves are opened to drain water from the separator and lockhopper back into a storage tank. The lock gas leaves the separator under pressure and may be applied to gas cleanup equipment.
