Abstract:
1. A method for producing methanol, comprising; producing oxygen in an air separation plant with air compressors driven by a gas turbine; heating a hydrocarbon feed stream using exhaust from the gas turbine; exothermically reacting a first portion of the heated hydrocarbon feed stream with at least one of steam or an oxidant gas comprising molecular oxygen to produce an exothermically generated syngas product; endothermically reforming a second portion of the hydrocarbon feed stream with steam over a catalyst in a heat exchange reformer to produce an endothermically-reformed syngas product, wherein at least a portion of heat used in generation of the endothermically-reformed syngas product is obtained by recovering heat from the exothermically-generated syngas product and the endothermically reformed syngas product; combining the exothermically generated syngas product and the endothermically-reformed syngas product to produce a combined syngas stream; producing steam in a waste heat boiler by cooling the combined syngas stream, where the combined syngas stream leaving the waste heat boiler has a pressure from 70 bar to 100 bar; separating water from the cooled combined syngas to produce a methanol plant feed at substantially reaction loop pressure and having less than about 2% CH after separating water, passing the cooled combined syngas to a methanol plant; and combining methanol plant combustible effluent with methane fuel to the gas turbine.
