Purified gas stream
HyGear’s De.OXO technology is an oxygen removal technology in-house designed for deoxygenation of the gases: biogas and hydrogen. Our Biogas De.OXO system removes residual oxygen from biogas to enhance the quality. Meanwhile, the Hydrogen De.OXO system removes oxygen from hydrogen. Removing oxygen from hydrogen gas is essential for safety, purity, and efficiency in industrial and energy applications including fuel cells and chemical processes.
Advantages
Oxygen removal from biogas
Oxygen removal from biogas and the removal of other impurities from biogas is an necessity in the U.S. bioenergy sector for safety, compliance, and efficiency. Deoxygenated biogas has more value, is safer, meets pipeline and RNG (biomethane) standards, prevents equipment corrosion, optimizes upgrading processes, and improves combustion efficiency. It qualifies for incentives like RINs and LCFS credits which in turn increases market value. Our De.OXO Biogas® is easy to integrate with any type of biogas upgrading system.
Oxygen removal from hydrogen
Oxyen removal from hydrogen is needed because the hydrogen gas derived from an elektrolyzer still contains water and hydrogen. Deoxygenated hydrogen is safer, meets purity standards, prevents corrosion, enhances industrial processes, and improves fuel cell performance. The De.OXO Hydrogen® is a compact system that fits a 20 ft. container and can be utilized with the Hy.GEN-E® and is easy to integrate with any other electrolyzer.
De.OXO in USA
For a project in Michigan, USA, we realized this system with a capacity of up to 2,000 Nm3/hr (1,250 SCFM). The low maintenance technology removes oxygen concentrations as high as 0.5% in conditioned biogas at low pressure (<1.5psig) and reduce them to below 5ppmv to meet the most stringent natural gas grid specifications. Low electricity consumption is achieved thanks to the De.OXO’s economizer shell and tube heat exchanger and its ability to operate at low pressure within the biogas to biomethane (RNG) upgrading process, thus eliminating the CAPEX and OPEX of an additional drying step. Projects previously inhibited from development due to stringent grid specs are now made possible with our De.OXO Biogas® technology.
