Production of cleaned and purified synthesis gas and carbon monoxide

Abstract From the Canadian patent

A continuous process for simultaneously producing a stream of cleaned purified synthesis gas having a mole ratio H2/CO in the range of about 2 to 12 and a separate, stream of CO-rich gas. In one embodiment of the process cleaned and purified methanol synthesis gas and substantially pure carbon monoxide are produced. Methanol may be synthesized and optionally catalytically reacted with the substantially pure carbon monoxide to produce acetic acid. In the subject process the effluent gas stream directly, from a free-flow unpacked noncatalytic partial-oxidation synthesis gas generator is split into two streams which are simultaneously processed in two separate trains. In the first train, one …
