PCI offers on-site oxygen production solutions that effectively remove hydrogen sulfide (H2S) from the biogas production process. These projects involve upgrading biogas from anaerobic digesters into natural gas quality by removing impurities. The use of higher purity oxygen to remove hydrogen sulfide is a simple, economical process that PCI provides to the biogas marketplace through our (DOCS) VSA Oxygen Generating Systems. This brings a tremendous contribution to safe, green, and optimal biogas plant operation. Our unique proprietary technology leads to 50% less power consumption compared to competitive technologies (PSA) which results in very low operating costs along with significantly less preventive maintenance during the year. Compared to using liquid oxygen (LOX), no more semi-annual or annual price increases/contracts. Become independent from your current oxygen supplier. PCI’s systems are fully automatic. Easy to operate and maintain.
