Abstract

Abstract Apparatus for generating high pressure synthesis gas containing hydrogen and carbon oxides and useful in Oxo processes, hydrogen production, and in the production of ammonia, methanol and the like. The apparatus includes a furnace, a novel arrangement of a combustion turbine exhausting into the furnace to supply preheated oxygen thereto and a sequence of heaters and reactors for alternately heating the reaction mixture in the furnace and adiabatically reacting the mixture outside the furnace to enable reaction and thus gas product at higher pressures than previously obtained. The mentioned heater-reactor sequence minimizes waste heat in the furnace and makes its recovery, e.g. as steam, no longer of such major economic importance to the process, enabling use of a combustion turbine both to supply preheated oxygen to the furnace and to drive plant machinery such as compressors for air to be fed to the secondary reformer in ammonia synthesis gas production.
