Irving Weiss is a notable inventor based in Merrick, NY (US), recognized for his significant contributions to the field of gas treatment technologies. With a total of 5 patents, Weiss has developed innovative solutions that address critical issues in the energy sector.

Latest Patents

One of Weiss's latest patents is focused on the cryogenic treatment of landfill gas to remove troublesome compounds. This process effectively eliminates compounds that cause severe corrosion in combustion engines using landfill gas as fuel. The method involves compressing the gas to an elevated pressure and isenthalpically expanding it to chill the gas to a temperature below -20°F. The gas is first cooled to eliminate moisture, and methanol is injected to prevent ice formation with residual moisture. The resulting aqueous methanol condensate, which contains troublesome compounds, is removed before the gas is expanded for refrigeration. By adding water to the aqueous methanol, the troublesome compounds lose solubility, allowing for easy separation and disposal. The diluted methanol can also be recycled.

Another significant patent by Weiss involves natural gas pretreatment prior to liquefaction. This invention addresses the challenge of conventional liquefied natural gas (LNG) plants, which are designed to eliminate moisture and up to 1.0% by volume of carbon dioxide (CO₂) in gas delivered by pipelines. Weiss's invention allows for the pretreatment of gas containing 1.5% to 3.5% by volume of CO₂, making it acceptable for LNG plants. The process includes scrubbing natural gas with cold methanol at temperatures below -30°F and flashing absorbed CO₂ from the methanol. The methanol can then be recycled to the scrubber, ensuring efficient operation.
