The hot combustion gases break the coal and steam down to form compounds containing carbon, hydrogen, sulfur, nitrogen and other elements, forming a raw gas which exits the gasifiers. Meanwhile, any ash resulting from the gasification process exits through the bottom of the gasifier. Simplified Plant Process at the Great Plains Synfuels Plant
A coalbased coproduction process of liquefied natural gas (LNG) and methanol (CTLNGM) is developed and key units are simulated in this paper. The goal is to find improvements of the lowearning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a lowmargin, single synthesis natural gas (SNG) product. In the CTLNGM process, there are two innovative ...
The more complex the gasification process, the more complex is the wastewaterprocessing scheme. On this basis, the movingbed technologies (Lurgi and British Gas/Lurgi) typically require the most complex wastewaterprocessing scheme, while the entrainedflow gasifiers require a relatively simple processing scheme. In either case, wastewater ...
As is well known, Lurgi gasification technology has low oxygen consumption and can produce a gaseous fuel with a relatively high CH 4 concentration and high ratio of H 2 /CO; thus, it is the main gasification technology of coaltoSNG at this stage. 12 However, a large amount of byproduct ash is discharged during the Lurgi gasification process ...
