Xebec Adsorption Inc., a
provider of biogas upgrading, natural gas and hydrogen purification solutions
for the clean energy market, says it has successfully completed its initial
phase testing for removal of high levels of N2 and O2 in
landfill and waste water treatment digester gas.
Xebec''s current BGX biogas
upgrading plants deploy single-stage advanced kinetic pressure swing adsorption
(kPSA) technology, capable of removing low to medium levels of N2, O2,
and CO2, while maintaining superior recovery rates. The current
technology has successfully proven its ability to remove medium levels of N2
and O2 at the biogas upgrading plant at the Escondido WWTP at
the Hale Avenue Resource Recovery Facility in Escondido, California.
The completion of this new
phase test program has allowed Xebec to increase its N2, O2
removal capability, and has validated the performance of high nitrogen and
oxygen removal of up to 15% nitrogen in the feed biogas. Xebec says it will
finalize the design and complete the phase testing using a two-stage PSA
process, which will achieve targeted recovery rates of >90% with >10%
nitrogen concentration levels in the biogas feed stream, within the next eight
Kurt Sorschak, President
and CEO of Xebec said, "The initial phase test results verifiably
demonstrate that our biogas upgrading technology will remove high levels of
nitrogen and oxygen with exceptional recovery rates. After the successful
completion of the test program in the second half of 2012, Xebec will offer
customers an upgrading solution with superior recovery rates than currently
available on the market.
Xebec is focused on the
landfill and waste water treatment segment, since both generate biogas with medium
to high levels of nitrogen and oxygen, and it is in these segments that Xebec''s
upgrading solutions offer a clear competitive advantage to our customers.
