5.1. Gasification Introduction netl.doe.gov
· Gasification Introduction. 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

Shell Gasification Process. In the Shell process the coal is finely ground and transported via a carrier gas into a gasifier. The control of the flow of the coal suspended in carrier gas is a critical and complex task for a control valve.Complex because the valve must be sized in a way to prevent settling of the coal in the valve which means maintaining certain minimum speeds of coal flow.

· Gasification of coal is a conversion technology which converts any carbon (C) containing material such as coal into synthesis gas (syngas). It is a high temperature process with temperature reaching typically 1 225 deg C. The temperature is optimized to produce a fuel gas with a minimum of liquid and solids.
