Claim:
1. A natural gas liquefaction facility, comprising: an electrical power source; a primary refrigeration unit for chilling natural gas to a temperature of liquefaction; a first refrigerant inlet line for delivering a first refrigerant to the primary refrigeration unit; a natural gas inlet line for delivering natural gas to the primary refrigeration unit; a natural gas outlet line for releasing a liquefied natural gas from the primary refrigeration unit; at least one superconducting electrical component which incorporates a superconducting material so as to improve electrical efficiency of the component by at least one percent over what would be experienced through the use of non-superconducting electrical components; an incoming refrigerant line for delivering a refrigerant to the at least one superconducting electrical component for maintaining the at least one superconducting electrical component below a critical temperature; an outgoing refrigerant line for releasing the refrigerant from the at least one superconducting electrical component; an ancillary refrigeration unit; an incoming refrigerant slip line, the incoming refrigerant slip line taking a portion of the first refrigerant from the incoming refrigerant inlet line and delivering the portion of the first refrigerant to the ancillary refrigeration unit as a third refrigerant; and an outgoing refrigerant slip line for delivering a portion of the third refrigerant to the incoming refrigerant line used for delivering a second refrigerant to the at least one superconducting electrical component.
