A New ERA in Waste Management

 


 


Gasification Offers Significant Environmental and Economic Benefits

When linked with modern combined cycle turbines, gasification is one of the most efficient, environmentally effective means of burning solid or liquid feedstocks.

Air emissions from a Gasification plant are far below U.S. Clean Air Act standards. Sulfur removal efficiencies of more than 99% are achievable. Reductions of emissions of SO2 , NOx, CO and particulate are significantly better than those achieved by scrubber-equipped, as well as Circulating Fluidized Bed Combustion (CFBC) plants on a fuel-by-fuel basis.

As air emissions standards become more strict, the superior environmental performance of gasification will take on added economic benefits because the technology can achieve greater emissions reductions at lower cost than less advanced technologies.

Gasifier can produces marketable byproducts, rather than large volumes of solid wastes typical of scrubber-equipped or fluidized bed combustion power plants using coal or petroleum-based fuels.

During gasification virtually all of the carbon in the feedstock is converted to syngas. Sulfur is removed from the syngas and captured either in elemental form or as sulfuric acid, both marketable items. The high temperature of the gasification process converts ash and other inert materials into a granular solid, thereby greatly reducing the volume of solids remaining after processing. This material is typically non-hazardous and can be used for many construction or building purposes.

Competing power generation technologies “circulating fluidized bed combustion (CFBC) and pulverized coal boilers with flue gas desulfurization (FGD)“ generate large amounts of spent solids as a result of sulfur removal from the combustion flue gases.Gasification can readily remove more than 98% of the sulfur while generating from one-sixth to less than one-eighth the amount of solid wastes. The solids remaining from FGD/CFB generation also have undesirable environmental characteristics (high pH and metals content), while the Gasification of solids are typically inert and can have a variety of uses.
