Clariant has been awarded a contract by Dongguan Grand Resource Science & Technology to develop a new propane dehydrogenation unit in cooperation with CB&I.
Munich/Germany — The project includes the license and engineering design of the unit, which is to be built in Dongguan City, Guangdong Province, China. The Dongguan plant will be one of the largest single-train dehydrogenation units in the world.
CB&I will base the plant’s design on the Catofin catalytic dehydrogenation technology, which uses Clariant’s tailor-made Catofin catalyst and Heat Generating Material (HGM).
The Catofin dehydrogenation process is a method for the production of isobutylene, propylene or amylenes from isobutene, propane or isopentanes respectively. The manufacturer claims that the process operates at optimum reactor pressure and temperature resulting in maximum conversion of propane and a high yield of propylene adding that this would also results in low investment and operating costs.
HGM is an metal-oxide material which is designed to increase the selectivity and yield of Catofin units. The material is loaded into the catalyst bed with the catalyst where it undergoes oxidation and reduction during the operating cycle, produces heat and drives the dehydrogenation reaction. These factors boost yields and save energy, as well as reducing emissions. This kind of metal-oxide has already been applied at several propane dehydrogenation plants in China and Korea.
