Honeywell to purify hydrogen for Zhejiang Satellite facility

Honeywell has announced that Zhejiang Satellite Petrochemical Co., Ltd is using a Honeywell UOP PolybedTM 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 OleflexTM 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.
“In the last five years, we’ve worked with Zhejiang Satellite to construct new petrochemicals facilities centred around our Oleflex technology, which helped to maximise operating flexibility and onstream reliability,” said Bryan Glover, Vice President and General Manager, Petrochemicals & Refining Technologies at Honeywell UOP. “Their selection of our PSA technology further enhances the reliability of their operations and provides a steady, stable source of high-purity hydrogen.”
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.

The EIA reports that US distillate consumption so far this year is lower than usual because of warm winter weather, reduced manufacturing activity, and continued substitution of biofuels in place of petroleum distillate on the US West Coast (PADD 5).
