PIONEER’s Rapid PSA-H2 technology can purify H2 from shift gas, coke oven gas, semiwater gas, methanol purge gas, methanol pyrolysis gas, ammonia pyrolysis gas, formaldehyde exhaust, refinery reformed gas, refinery FCC dry gas and refined gas.
Technical Advantages of PSA-H2
1. Innovative Process Design
PIONEER’s innovative Rapid PSA-H2 process features shorter period and smaller bed size in comparison with the existing process, which greatly reduces the investment and operating cost.
2. Independently-developed Adsorbent
PIONEER’s independently-developed and produced PSA-H2 adsorbent has excellent performance indicators and features high capacity and flexibility of feed gas.
3. Outstanding Product Index
The high purity (up to 99.999%) and recovery (≥90%) of H2 products are of great importance for energy conservation and efficiency improvement.
Typical Applications of PSA-H2
1. Application in chemical synthesis
Currently H2 is mainly used as intermediate or raw material for chemical synthesis, for example, of ammonia, methanol, ethylene glycol, butyl alcohol and phosgene for further generating TDI and MDI, etc..
2. Application in petroleum refining
H2 is applied in various processes of petroleum refining and petrochemicals, including hydrocracking, catalytic hydrogenation, hydrotreating, hydrodesulphurization and benzene hydrogenation to cyclohexane.
3. Application in modern coal chemical industry
H2 can be used for direct or indirect synthesis of liquid fuels, olefins and other important chemical products, for example, direct coal liquefaction, indirect coal liquefaction (F-T synthesis) and coal-to-substitute natural gas (methanation), etc.
4. Application in reduction
H2 is widely used as reducing gas in heat treatment and production of metal hydride.
