For many years, the scientific community has been working to commercialize various “green” power technologies, including solar, wind and waste-to-energy conversion.

 

Each of these areas of investment has had moderate returns at best. Various waste to energy conversion technologies, ranging from incineration to pyrolysis, have had limited effectiveness. Most recently, particular interest has been paid to the gasification of municipal solid waste and various high-carbon waste products.

Traditional gasification processes use heat, pressure, and steam to convert complex organic molecules into simple gases. Although they have been in use for several years, current gasification technologies have had limited success due to relativity low energy recover rates (45-55%). Of all the potential energy inputs from electric and raw materials, approximately half is recovered for use. The remainder is trapped in leftover byproducts and lost as heat. Plasma gasification offers advantages over traditional methods.

 

Plasma Gasification is not a new technology.  It has existed in some form since the 1600s, but COH2 Energy’s Plasma Gasification system is a 21st century solution to a 21st century problem.

 

Our system integrates technical advancements in equipment, materials, process controls and instrumentation, allowing for a highly controlled, extremely high temperature plasma environment. The same high-carbon waste products, along with inherent non-carbon wastes, immediately begin to break down from solid waste material into their individual molecules.

As these molecules are further ionized to their atomic state, the vast majority of non-carbon molecules are tied up and vitrified into molten silica. The ionized carbon and hydrogen atoms are allowed to reform in the oxygen-controlled environment where natural reformation occurs. Light gases of carbon monoxide and hydrogen rise for extraction as Syngas (Synthesis Gas), while heavier elements progress downward toward the molten silica and the heaviest metal elements reform at the base of the system.  Syngas is captured, cleaned of any impurities, and sold or processed into other products.
