Xebec Expands Its Gas Upgrading And Conditioning Solutions With High Efficency Membranes

Xebec Adsorption Inc., a provider of gas purification and filtration solutions for the natural gas, field gas, biogas, helium, and hydrogen markets, announced today that, effective immediately, it will be integrating high efficiency membranes into its gas purification and separation solutions. Xebec has historically been offering gas purification and conditioning solutions solely based on adsorption technology. After an in-depth evaluation of membrane technologies, Xebec will now offer standalone membrane solutions, as well as hybrid (membrane + adsorption) solutions, which are able to achieve recovery rates and purity levels so far unobtainable with adsorption technology alone. For biogas upgrading applications, Xebec membrane systems will achieve recovery rates of up to 99.8%, while meeting stringent product gas specifications. For biogas or landfill gas applications containing nitrogen (N2) and oxygen (O2), Xebec offers advanced fast cycle kinetic pressure swing adsorption (kPSA) solutions that can handle nitrogen levels of up to 30% with excellent recovery rates. For hydrogen applications, Xebec now integrates membranes into its overall system design, which results in significantly higher overall recovery rates, while still being able to meet extremely stringent product gas specifications of up to 99.9999% (6 nines) pure hydrogen. Xebec has been designing advanced Helium (He) recovery systems for several years, but has just recently developed a hybrid helium purification and conditioning system that will take low helium concentrations from a gas well, typically 0.6% to 2.5% of helium, and purify the gas stream to 99.999% (5 nines) pure helium, while achieving recovery rates of up to 95+%. After the helium purification step, the product helium gas can be liquefied or compressed for further monetization. Thanks to the fast cycle PSA technology of Xebec and the utilization of high performance membranes, these helium purification systems have a relatively small footprint, and can be deployed in remote areas.
