Gasification is a technological process that can convert any carbonaceous (carbon-based) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material …

Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar.
As the flue gas flow diagram of the thermal power plant shows, after the combustion process, the flue gas which has a sufficient quantity of heat is made to pass boiler tubes, dust collectors, economizers, and Preheater before passing out through a chimney. The water and air get preheated by passing the flue gas around the …
Figure 1 shows a simplified block flow diagram (BFD) of a methanol (MeOH) plant based on coal feedstock. Syngas from the gasifier is cooled by generating high pressure (HP) steam in the high temperature (HT) gas cooling system before being water quenched and scrubbed to remove fine particulates. The scrubbed syngas then goes through a sour …
