Using natural gas to produce methanol involves issues related to conversion efficiency, and there are certainly requirements regarding the methane content. What I want to know is, what must the methane content be above? What must the sulfur content be below? Are there any requirements for other heavy alkanes?
In traditional steam conversion, the methane content is generally kept below 3%; in such processes, carbon dioxide from the flue gases needs to be recovered in order to supply carbon and increase the alcohol yield. Pure oxygen autothermal conversion generally keeps methane at less than 0.5%, but requires large-scale air separation support. Small-scale units can handle solid desulfurizers up to a sulfur content of 0.2%, while large-scale units can handle it up to 0.05–0.1%; wet desulfurization is required when the sulfur content is high.
