Optionally high-purity hydrogen can be generated by applying pressure swing adsorption (PSA). The fractionation unit of a dehydrogenation plant consists of a stripper column to remove light uncondensables, which are fed to the gas separation unit, and a splitter column to separate olefin product and unconverted paraffin.

Low reactor/catalyst volume: The STAR process ® reformer is the only PDH reactor system commercially available with direct heating of the reaction zone, thereby significantly increasing reaction velocity. This results in the lowest catalyst inventory / reactor volume on the market.

supplier for submarines and surface vessels. As an important system partner to our customers in the automotive, aerospace and battery industries, we opt. and as by-product in FCC units (approx. 30%). Approx. 20% is produced by on-purpose technologies lik.

2022年4月26日 · BASF and thyssenkrupp Uhde achieved measurable improvements in the STAR process ®, a proprietary dehydrogenation process from thyssenkrupp Uhde that can produce propylene from propane feedstocks, or iso-butylene from iso-butane feedstocks.

The STAR process ® reformer is the only PDH reactor system commercially available with direct heating of the reaction zone, thereby significantly increasing reaction velocity. This results in the lowest catalyst inventory / reactor volume on the market. The system is simple, reliable and robust in operation and offers
