Honeywell announced that Zhejiang Satellite Petrochemical Co., Ltd. is using a Honeywell UOP Polybed™ pressure swing adsorption (PSA) unit to supply high-purity hydrogen to its integrated refining and petrochemicals complex in China. The PSA unit purifies hydrogen generated by its UOP C3 Oleflex™ propane dehydrogenation unit.
Zhejiang Satellite, which recently announced a second C3 Oleflex unit to meet the growing propylene demand in China, has used the PSA technology to upgrade the purity of hydrogen to meet refining needs. In addition to technology licensing, Honeywell UOP provided services, equipment, catalysts and adsorbents for the Satellite plant.
The PSA process uses proprietary UOP adsorbents to remove impurities at high pressure from hydrogen-containing process streams, allowing hydrogen to be recovered and upgraded to more than 99.9% purity to meet refining needs.
In addition to recovering and purifying hydrogen from steam reformers and refinery off-gases, the Polybed PSA system can be used to produce hydrogen from other sources such as ethylene off-gas, methanol off-gas and partial-oxidation synthesis gas. Polybed PSA systems are skid-mounted, modular units complete with hardware, adsorbents, control systems and embedded process technology, enabling quick and efficient installation to reduce cost and downtime.
