Cenergy Solutions, a US-based company, in conjunction with North State Rendering Plant has captured biogas that is being made from food waste. This gas is now being moved in Cenergy’s ANG trailer to be utilized in a boiler that is preparing used cooking oil for biodiesel production. Chris Ottone plant co-owner of the biogas plant, said this could save them $3,000 to $4,00 per month which is now being spent on pipeline gas from PG&E.
Cenergy Solutions, CEO Gary Fanger says, “This is a game changer for the biogas industry. This raw biogas is being moved with the CO2 to a location that can utilize it in a boiler. The raw biogas can also be moved to a processing plant where it can be scrubbed and injected into the pipeline. We have now demonstrated that Cenergy’s ANG tank trailer can move stranded biogas to replace other fossil fuels in vehicles and other applications, something that has never been in a tank trailer before. Over the next two weeks we will also demonstrate that we can use ANG tanks filled with biogas and wellhead gas to replace propane usage in homes and businesses. This will help to stop the waste of our renewable and natural resources which are taking place worldwide”.
Cenergy’s tests on their ANG tank trailers have gone as expected with both pipeline and biogas being economically and safely stored and transported to an end use at pressures less than 265 psi. The last test was done with raw biogas that only had the moisture and H2S taken out. Cenergy has shown that the ANG tank trailer can be fast filled with a high-pressure dispenser or slow filled with a low-pressure screw pump making it versatile for many applications. The adsorption and desorption are enhanced with Cenergy’s patented ANG system making it possible to fill the ANG tank trailer quickly and dispensing it fast or slow as needed for the application that it is being used for. The natural or biogas that leaves the tank has a consistent flow down to 0 psi in the tank. There are no problems with freezing that restricts the flow or liquifying the CO2 during adsorption or desorption.
