Claim:
1. A supplemental cooling system for chilling a process feed gas, which comprises: a liquid chiller ejector system; a steam input line in fluid communication with the liquid chiller ejector system; a chilled liquid line wherein each end of the chilled liquid line is in fluid communication with the liquid chiller ejector system; and a heat exchanger enclosing a portion of a process feed gas line and a portion of the chilled liquid line, wherein the process feed gas line and the chilled liquid line are positioned in sufficient proximity to each other in the heat exchanger to affect heat transfer between the process feed gas when the process feed gas passes through the process feed gas line and a chilled liquid when the chilled liquid passes through the chilled liquid line; wherein the heat exchanger encloses a portion of a refrigeration intercooler line and a portion of a refrigeration aftercooler line, the refrigeration intercooler line and the refrigeration aftercooler line each positioned in sufficient proximity to the process feed gas line and the chilled liquid line in the heat exchanger to affect heat transfer between the process feed gas when the process feed gas passes through the process feed gas line, the chilled liquid when the chilled liquid passes through the chilled liquid line, a refrigeration intercooler when the refrigeration intercooler passes through the refrigeration intercooler line and a refrigeration aftercooler when the refrigeration aftercooler passes through the refrigeration aftercooler line.
