General information
Grasys membrane hydrocarbon plants allow dramatically adjusting the properties of such gas through the removal of a large part of heavy hydrocarbons (C4+). Thereby, methane is mainly concentrated in the retentate with a 0.5–4.0 bar pressure drop against the feed flow pressure, which is especially important in fuel gas the treatment for gas-fired reciprocating plants. Additionally, membrane plants allow reducing the content of sulfur-bearing impurities in the fuel gas and completely excluding aerosols, condensed moisture and solid particles.
The degree of fuel gas treatment may vary significantly depending on the feed gas quality and the requirements set with regard to the product gas.
