ABSTRACT:
The waste heat of an open gas turbine system used to heat a flow of liquified natural gas is recovered and passed via an intermediate heat exchange circuit or system to the flow of liquified natural gas. The intermediate circuit uses hydrocarbons which may or may not have been halogen-substituted as the heat exchange medium. The heat is extracted from the flue by closed piping systems which use water as a heat carrier as well as a system which uses an anti-freeze agent such as methanol. The anti-freeze circuit permits injection of the anti-freeze agent into the intake of the gas turbine while a rectifying column allows recovery of the anti-freeze agent. The intermediate circuit includes a vapor turbine which expands the hydrocarbon medium after the hydrocarbon medium receives heat in order to produce useful work.
