| Other | 55 | VOC control for tail gas emissions. As part of the purification process to transform biogas into RNG, some CH4 (methane) is stripped out as “tail gas,” along with the CO2 and other residual constituents such as VOCs, siloxanes, and H2S. This tail gas is typically routed to a flare or thermal oxidizer for destruction. The amount of methane removed during this process depends on several factors, including the technology used to upgrade the gas, the methane content required by the end user, and the cost benefit of additional methane capture considering the capital expense to achieve it. |
