Clariant to design new propane dehydrogenation unit in China


Clariant has signed an agreement with Xuzhou HaiDing Chemical Technology to develop a new CATOFIN catalyst and propane dehydrogenation (PDH) unit in Pizhou, Jiangsu Province, China.

Clariant will carry out the project in alliance with its technology partner CB&I. The agreement covers licence and engineering design of the custom-built plant.

The unit will be designed based on Clariant's CATOFIN catalytic dehydrogenation technology to produce 600kt of propylene per annum.

Clariant's technology utilises CATOFIN dehydrogenation catalyst that is used for producing olefins from light paraffin feedstocks, along with heat generating material (HGM) loaded with the catalyst to enhance selectivity and yield of CATOFIN units.

"Nine CATOFIN propane dehydrogenation units have been commissioned to date, producing more than 4,500kt of propylene per annum."

The process uses thermodynamically advantaged reactor pressure and temperature with a highly selective catalyst to ensure maximum yield of propane to propylene.

Clariant Catalysts business unit senior vice-president and general manager Stefan Heuser said: "Clariant has always led the way in developing ground-breaking catalyst technologies, so we are honoured to be part of this important project for Xuzhou HaiDing Chemical Technology in China."

Nine CATOFIN propane dehydrogenation units have been commissioned to date, producing more than 4,500kt of propylene per annum.

CATOFIN is reported to deliver a favourable return on investment by functioning at higher than 110% of designed capacity with an on-stream time of around 98%.
