H2 Purification

H2 requirements are growing world wide due to the increased use of hydro-treating and hydro-cracking for cleaner and higher-value fuels as well as demand for chemical products and production of electronics. The processes using and/or generating H2, typically create residual gas streams or byproducts that still contain a significant amount of valuable H2. SMC-IGS provides customized H2 recovery membrane systems with minimal losses of 1 to 10% H2. H2 product purities range from 90 to 99.9%. Alternate technologies to recover and purify hydrogen rich gas streams include PSA (pressure swing adsorption) technology. SMC also offers HYDROSWING® PSA technology to customers that require ultra-pure hydrogen (99.9% to 99.999+%). Performance ��Feed gas pressures up to 2,000psi (138bar) ��90% to 99% hydrogen recovery ��Lower maintenance cost (no switching valves) ��Hydrogen purities to 99.9% ��F

Natural Gas Purification

Biogas Purification

During anaerobic digestion or degradation in the absence of oxygen, organic material is decomposed by bacteria forming biogas, a mixture of CO2 and CH4 with trace amounts of H2S and H2O. The biogas can be used as vehicle fuel, in industrial processes or injected into the gas distribution grid, but first needs to be treated. SMC 's membrane systems are used to reduce the CO2 and improve the heating value of the gas. The systems also reduce the H2S and H2O content. SMC supplies customized biogas treatment systems, which also include the feed compression.SMC fabricates membrane modules and works directly with the client to provide the most cost effective solution. The other alternatives for biogas treatment are absorption (water wash) or adsorption (PSA) systems. These systems are complex and have high capital, operating and installation cost as compared to membranes. Performance ��Fe
