Syngas (H2 + CO + others) is used to produce a variety of products. Each product requires a specific ratio of H2 to CO in the process feed gas to optimize production yields. Feed streams too rich in H2 can be adjusted by using membranes to selectively strip out the excess H2. The H2:CO ratio can be optimized effectively using GENERON® membrane systems.
GENERON® will boost the yields through system designs and blending schemes that take full advantage of GENERON® membranes high selectively for H2. The vented off-gas of H2 can be at purities over 96%. Control of the process is simple with multiple membrane filters® controlled by a single flow control valve.
Depending on the feed composition, one can purify CO with GENERON® membrane to over 95% with greater than 90% CO yields. If higher purities are required and/or if nitrogen is present in the CO rich feed gas, GENERON's PSA (pressure swing adsorption) can be used to achieve purities up to 99.99%.
In a typical GENERON® membrane system for H2:CO ratio adjustment, the feed gas is filtered to remove particles and condensate and then heated to an optimum operation temperature and ready to enter the GENERON® membrane filters. Hydrogen gas permeates through the membrane walls creating a hydrogen rich permeate stream. CO2 and H2O, as well as H2S, are enriched in the permeate stream and may be lowered by this same process. The hydrogen-reduced CO richer product gas remains at pressure in the non-permeate ("retentate") stream.
