This project is a gas separation unit for the refining facility of Shandong Kelin Petrochemical Co., Ltd., using pressure swing adsorption technology to purify hydrogen from the reformate gas for use in the hydrogenation unit.

The designed processing capacity of the unit is 1×10⁴Nm³/h, processing the reformate gas from the heavy oil catalytic cracking unit.

The hydrogen content in this gas is approximately 75-80%, and the CO₂ content is approximately 15-20%. The PSA system adopts a ten-tower configuration, optimizing the adsorbent ratio and process sequence for the high CO₂ content characteristic.

The product hydrogen purity can reach 99.9%, and the hydrogen recovery rate exceeds 90%. The daily hydrogen production is 240,000 Nm³.

The designed pressure of the unit is 2.5 MPa, using high-pressure dedicated adsorption towers and valves to ensure long-term stable operation of the system. The on-site installation period is 5 months.

Considering the corrosive environment in coastal areas, key equipment uses stainless steel materials and special anti-corrosion treatment. After the installation, the annual recovered hydrogen volume exceeds 87 million Nm³, significantly reducing the raw material cost of the hydrogenation unit and improving the overall economic benefits of the refinery.
