Honeywell UOP said its 1,000th system for purifying hydrogen is being installed at Ruwais Refinery, United Arab Emirates, and operated by the Abu Dhabi Oil Refining Company (TAKREER).
The UOP Polybed PSA system will recover and purify hydrogen for TAKREER’s Carbon Black and Delayed Coker Project to meet the increasing need for clean transportation fuels. UOP first invented the Polybed PSA technology in 1966 and has supplied improved versions of the technology to meet the growing global demand for hydrogen. Hydrogen upgrades heavy crude oils into refined fuels and helps meet increasingly tight transportation fuel specifications.
The 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 percent purity to meet refining needs. In addition to recovering and purifying hydrogen from steam reformers and refinery off-gases, Polybed PSA Systems can be used to produce hydrogen from other sources such as ethylene off-gas, methanol off-gas and partial oxidation/synthesis gas.
The first small, four-bed hydrogen PSA system was commercialized in 1966.
