Biogasclean specializes in removing H2S from biogas without the use of chemicals.
Hydrogen sulfide (H2S) is a strongly odorous gas that can corrode digester and energy generation components and is a serious health and safety threat. It is often referred to as “sewer gas” and is particularly present in wastewater and digester environments. Cost-effective solutions for H2S removal are in high demand to minimize OPEX costs, reduce equipment failures, and eliminate nuisances like odor.
Biogasclean’s systems can reduce H2S concentration down to 50 ppm, after which the biogas can be used for electricity, heat or biomethane (RNG) generation.
In Denmark the winning concept for RNG production is upgrading with an amine scrubber and biological removal of the H2S from the off-gas stream, yielding up to 99.9 percent methane recovery and the lowest operating costs of any RNG solution. The Biogasclean system is installed at several RNG projects, the largest one producing more than 1,050 million SCF per year of biomethane and reducing H2S from 8,000 ppm to 50 ppm in the off-gas.
Biogasclean offers tailored solutions for small and large-scale installations. The company provides fully automatic gas cleaning systems that combine low operating costs with high availability. The QSR® technology makes it possible to periodically clean the packing media inside the tank.
Biogasclean has +285 plants in operation or under construction in 40 countries of which more than 20 are located in North America. Currently, Biogasclean has 4 projects under execution in the USA: One municipal WWTP and one hog production in Texas; one industrial WWTP in Missouri; and one dairy project in California.
