Title: Production of synthesis gas by partial oxidation and high-pressure shift conversion

Journal Article · · Plant/Oper. Prog.; (United States)

A fifteen-year history account of process improvements at the BASF ammonia plant at Ludwigshafen, West Germany is presented. Heavy fuel oil with a sulfur content of 1.75% (by weight) and with an ash content of about 0.015% (by weight) is used as feedstock at the plant. The fuel oil is converted with oxygen and steam to synthesis gas at a pressure of 80 bar. The synthesis gas generation is followed by raw-gas preheater, a two-step water-gas shift conversion, and a subsequent waste heat recovery. Sulfur compounds and CO/sub 4/ are removed from converted gas in a combination of a TEA- and an Alkazid-scrubber. Final purification and nitrogen enrichment is achieved in a liquid-nitrogen scrubber. The NH/sub 3/ synthesis operated at 350-430 bar, at which pressure NH/sub 3/-refrigeration of the recycle loop and purge gas removal are not necessary. (JMT)
