The two plants, which together feed 800 Nm3/h of biomethane into the local gas grid, are the first UGS systems of their kind.
The two projects exemplify the company's commitment to developing innovative and sustainable gas upgrading systems and offering economical solutions even under unusual conditions.
The projects were particularly challenging due to the change in operating procedures and the high grid requirements.
The first commissioning, the Three Petals RNG plant in Berlin, Wisconsin, was followed by the second - the Red Leaf RNG plant at the Maple Row Dairy Farm in Saranac, Michigan.
“Remarkably, the desulphurisation via the membrane unit itself, followed by the fine desulphurisation on the product gas side, means that the grid specifications can sometimes even be met without using the De-Oxo system. However, the DeOxo system offers absolute safety for all our sites”, said Mark Hill, Co-CEO of Novilla RNG.
“This is because the oxygen remaining in the product gas is consumed in the reaction beds of the fine desulphurisation system during the reaction of H2S to Fe2S3, so that the limit value of 5 ppm can be met even without the DeOxo unit installed.”
“We have innovative solutions that can fill critical niches in this market. UGS offers systems manufactured both in the USA and in Europe, ensuring innovative solutions for the upcoming market requirements,” added Ben Bikson, CTO of UGS LLC.
