System and method of interfacing intercooled gas turbine engine with distillation process

Abstract:

A system includes a gas turbine system having a heat recovery steam generator (HRSG), a compressor, an intercooler, and a steam turbine. The HRSG is configured to receive an exhaust gas, heat a first working fluid with the exhaust gas, and route the first working fluid to the steam turbine, where the steam turbine is configured to extract energy from the first working fluid, and where the intercooler is configured to receive a compressed air from the compressor of the gas turbine engine and to cool the compressed air to a first controllable temperature determined by engine controls with a second working fluid having a second controllable temperature suitable for cooling the compressed air to the first controllable temperature determined by the engine controls. The system also includes a first feed heater of a distillation system, where the first feed heater is configured to receive the mixture and the second working fluid such that the second working fluid sinks heat to the mixture. The system also includes a first-effect vessel of the distillation system. The first-effect vessel is configured to receive the mixture from the first feed heater and to receive the first working fluid from the steam turbine, such that the first working fluid sinks heat to the mixture.
