Title: Innovations by Stephen J Markbreiter
Introduction
Stephen J Markbreiter is a notable inventor based in Edison, NJ (US), recognized for his contributions to the field of environmental technology. He holds a total of 7 patents, showcasing his innovative approach to solving complex problems related to gas treatment and energy generation.
Latest Patents
One of his latest patents involves the cryogenic treatment of landfill gas to remove troublesome compounds. This innovative process addresses the severe corrosion issues faced by combustion engines that utilize landfill gas as fuel. The method includes compressing the gas to an elevated pressure and isenthalpically expanding it to chill the gas to a temperature below -20 degrees Fahrenheit. Initially, the gas is cooled to eliminate moisture, and methanol is injected to prevent ice formation with residual moisture. The process results in an aqueous methanol condensate that contains troublesome compounds, which can be separated for disposal. Additionally, the diluted methanol can be recycled, enhancing the sustainability of the process.
Another significant patent by Markbreiter focuses on the cogeneration of electricity and liquid carbon dioxide through the combustion of methane-rich gas. This method powers both a gas turbine and a steam turbine, with each turbine driving an electric generator. Carbon dioxide is separated from the combustion products using an amine absorption system, with heat supplied by steam drawn from the steam turbine. The process also includes producing refrigeration with an ammonia absorption refrigeration unit, which is applied to liquefy the separated carbon dioxide. This innovation not only generates electricity but also provides saleable refrigeration as an optional product.
