Words from the finalist…
Air Products Membrane Solutions is nominating our team for the Research and Innovation Award for developing and commercializing our cutting-edge membrane separator for bio-LNG production. In the production of (bio-)LNG, a market standard at the inlet of a liquefaction process is <50 ppm CO2. Common methods to reduce the CO2 concentration at the inlet of the liquefaction process typically include amine scrubbing or thermal swing adsorption (TSA). Our team has successfully developed a specialized membrane called GreenSep LNG and an associated, proprietary membrane cycle that meets <50 ppm CO2 at the outlet of the membrane unit, thus eliminating the requirement for an intermediate method to reduce the CO2 concentration. This leads to reduced CAPEX, decrease in OPEX, and increased LNG production. The membrane and the associated cycle can be used for new installations, as well as to retrofit existing biogas upgrading plants that are converting to bio-LNG production. This offering allows for simple and direct biomethane to bio-LNG production with a normal power consumption in combination with an increased bio-LNG recovery.
PRISM GreenSep LNG has been recognized by the Italian Exhibition Group at the 2024 edition of Ecomondo, where it was awarded the Lorenzo Cagnoni Award for Green Innovation.
