  • METHOD AND APPARATUS FOR COOLING AND LIQUEFYING A HYDROCARBON STREAM
    Publication number: 20100263406
    Abstract: Method of driving two or more refrigerant compressors in a hydrocarbon cooling process. In such a hydrocarbon cooling process a hydrocarbon feed stream (10) may be passed against partly evaporating refrigerant streams. The at least partly evaporated refrigerant streams (35a, 37a) are compressed through refrigerant compressors (34, 36). One or more gas turbines (54) are driven to provide electrical power (56) and hot gas. The hot gas (57) is passed through one or more steam heat exchangers (58) to provide steam power, which is used to drive one or more steam turbines (82) to drive at least one of the refrigerant compressors (34). The electrical power is used to drive (76) at least another one of the refrigerant compressors (36).
