Propylene, Iso-butylene BASF, thyssenkrupp Uhde Enhance Dehydrogenation Process

The proprietary ‘Star’ dehydrogenation process which can produce propylene from propane feedstocks or iso-butylene from iso-butane feedstocks has been optimized by thyssenkrupp Uhde and BASF. The technology is now capable of reducing CO2 emissions and operating costs through lower energy consumption by up to 30 %.

Ludwigshafen/Germany – 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 technology has been optimized to reduce CO2 emissions and operating costs through lower energy consumption by up to 30 %, while also reducing investment costs and enabling additional feedstock savings. Started in 2020, thyssenkrupp Uhde focussed in this joint development on the optimisation and further development of the Star process, while BASF validated the targeted improvements through an extended test program.

“The cooperation between BASF and thyssenkrupp Uhde over the past 18 months since announcing the joint development agreement has been exceptional and seamless”, says Guido Daniel, Executive Director Petrochemicals and Polymers at thyssenkrupp Uhde. “In a joint team effort, both partners have provided their specific expertise to improve the dehydrogenation process. The results show that we significantly exceeded our goals to reduce the consumption of energy and resources of the Star process.”
