Abstract
A cryogenic pump manifold with subcooler and heat exchanger. The manifold comprises an inlet header with a subcooler disposed around it and a heat exchanger on the inlet side of the inlet header and subcooler. An expansion device is disposed between the inlet header and subcooler, and some liquid is diverted from the header and evaporated into a gas through the expansion device thereby lowering the temperature of the expanded gas which provides significant cooling to the cryogenic liquid entering the suction of the pump. An ejector may be positioned in the exhaust line from the heat exchanger to increase the flow rate, resulting in even more cooling. The cooling improves the overall performance of the pump and increases the ambient temperature range of operation of the pump. A method of cooling cryogenic liquid entering the suction of a pump is also disclosed.
