Abstract
A cooling system is provided for cooling a motor that drives a compressor in a liquefaction system. The coolant used for cooling the motor includes portions of a discharge from a compressor. The coolant for the motor is generated from a vapor component of the discharge from the compressor. The discharge from the compressor is cooled and the vapor component is separated from a liquid component and treated prior to being introduced into the motor. Remaining portions of the discharge from the compressor are routed to cold boxes producing a compressed refrigerant.
