Improved CI score

The biogas upgrader, a PurePac Grand, in Idaho in the USA, significantly improves the CI score of the client. The plant uses membrane technology, meaning the gas is separated utilizing an imposed pressure difference over the membrane. Two gas streams will be obtained from the plant, a product gas with a high methane value and a CO2-rich gas. Using membranes with high separation efficiency allows recovery of the highest possible methane yield.

RNG production

RNG produced
0 million SCFM / year
CO2 savings
0 metric tons / year

The biogas purification system has a pretreatment of the raw biogas and membrane separation technology, which results in high-quality and efficient renewable natural gas production. The client produces 670 SCFM of RNG per hour, effictively converting organic waste into renewable natural gas.
