After successfully concluding the FEED study in June 2018, Borealis has taken the final investment decision for a new, world-scale propane dehydrogenation (PDH) plant. The facility with a capacity of 750,000 tonnes per year will be located at the existing production site in Kallo (Antwerp), Belgium. The plant is scheduled to start up in the first half of 2022.
Vienna/Austria; Kallo/Belgium —The PDH plant will be one of the largest and most efficient facilities in the world, the company announced. The Kallo location was selected due to its excellent logistical position, its experience in propylene production and handling and the synergies with the existing PDH unit. The company will use Honeywell UOP’s Oleflex technology for the new plant, which is a widely used choice for on-purpose propylene production. Propylene is one of the most important building blocks for the entire chemical industry, in which the plastic polypropylene has strong growth figures worldwide.
Oiltanking Antwerp Gas Terminal will be the long-term logistics partner for the handling of propylene and the raw material propane and will construct a new 135,000 m3 propane storage tank. The hydrogen that is a by-product of the dehydrogenation process will be sold to Air Liquide under a long-term agreement. The approved investment also provides for the possibility to include efficient cogeneration as part of the project. Such energy efficiency technology could contribute substantially to the Flemish climate and energy objectives, as well as to the energy efficiency plan of the Flemish Region. The support of the Combined Heat and Power (CHP) will also be decisive in the final technical concept.
