Abstract (en)
A method for lubricating a screw expander (16) includes condensing a mixture of working fluid and lubricant fed from the screw expander (16), through a condenser (18). At least a portion of the mixture of working fluid and lubricant fed from the condenser (18) is pressurized from a first pressure to a second pressure through a pump (20). The method also includes separating the lubricant from the condensed working fluid of the at least portion of the mixture via a separator (22) and feeding the lubricant to the screw expander (16); or separating the lubricant from the working fluid of the at least portion of the mixture via an evaporator (14) and feeding the lubricant to the screw expander (16); or feeding the at least portion of the mixture of condensed working fluid and lubricant to the screw expander (16); or combinations thereof.
