Modern electronics, pharmaceutical, and food industries require Hydrogen purities exceeding 99.9999%. Chemical Design, Inc. can upgrade lower purity process streams economically with our cryogenic adsorption process. Hydrogen can be obtained with impurities such as CO, CO2, O2 and CH4 removed to the part per billion range. This allows the customer to recycle the purified hydrogen and realize significant savings in plant costs. The picture depicts a CDI hydrogen purification system during installation at the customer facility.
