Abstract

The North Alabama coal-to-methanol plant is designed for 99.7% sulfur removal. The plant will produce about 2000 metric tons of methanol a day by indirect coal liquefaction of eastern bituminous coal. The high sulfur removal efficiency will be achieved by designing the acid gas removal unit to supply a concentrated H/sub 2/S rich feed to the sulfur recovery unit, while producing a low sulfur CO/sub 2/ waste gas, by routing the various sour gas streams in the plant to the sulfur recovery unit for treatment, and by control of sulfur storage tank emissions. 7 references, 7 figures, 3 tables.
