Abstract
The present invention relates to an improvement to a process for the production of methanol from synthesis gas containing carbon monoxide and hydrogen utilizing a three phase or liquid-phase reaction technology. The improvement to the process is the addition of relatively small amounts of water to the liquid-phase reactor thereby allowing for the use of a CO-rich synthesis gas for the production of methanol by effectuating in the same reactor the methanol synthesis and water-gas shift reactions. A portion of the unreacted synthesis gas stream from the liquid-phase reactor is separated into a hydrogen-rich component and a carbon monoxide-rich component. The hydrogen-rich component is combined with a portion of the unreacted synthesis gas stream from the liquid-phase reactor to form a gas-phase methanol reactor feed stream for producing methanol, and the carbon monoxide-rich component is combined with the unreacted effluent from the gas-phase methanol reactor to form a feed stream for combustion in a gas turbine.
