SynGas Cleanup | Nanocomposite Membrane Filtration System

Syngas contains a variety of contaminants produced from impurities present in the feed material gasified. Syngas produced from biomass contains acid gases including HC l, HCN, and H 2 S. It also contains NH 3 and COS. All of these components must be removed to avoid poisoning of catalysts used in downstream upgrading processes.

Coal and clean coal tech. -ill-sec

Coal gasification can also take place underground. In underground gasification, steam and oxygen are injected into a coal seam through wells drilled from the surface. The coal seam is ignited and partially burned. Heat generated by the combustion gasifies additional coal to produce fuel-grade gases.

Gasification | WCA

Gasification can also be used for power generation. IGCC plants use a gasifier to convert coal (or other carbon-based materials) to syngas, which drives a combined cycle turbine. Coal is combined with oxygen and steam in the gasifier to produce the syngas. The gas is then cleaned to remove impurities, such as sulphur, and the syngas is used in ...

Gasification and Energy Independence

At its core, gasification is recycling being performed at the molecular level and this is what makes gasification an ideal technology for programs focused on energy independence. Unlike most energy technologies, gasification can use virtually any feedstock on the input side of the system. If it contains carbon and hydrogen, it can be gasified.

COAL GASIFICATION || STONETEK ENERGY

Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator.
