Located in Ulsan on the southeast coast of the country, the PDH plant is a joint project between SK Gas Corp. Ltd. and Advanced Petrochemical Co.

The Catofin process is recognized as a reliable and efficient technology for producing propylene from propane. The process operates at optimum reactor pressure and temperature to maximize conversion of propane for a high yield of propylene and correspondingly low investment and operating costs.

These performance benefits were confirmed by the successful startup of the PDH plant in Ulsan, according to Clariant. The unit has achieved a fast startup time with on-spec propylene produced within one day of propane feed introduction. 100% of design capacity was available in less than 15 days, and the plant is currently operating slightly above 100% capacity. Design conversion rate has already been reached at lower than expected temperatures. 

In addition to supplying leading catalyst products, Clariant’s Catalysts business unit offers customers comprehensive service. Dedicated support from Clariant and CB&I begins with providing process information during the initial stages of plant design and construction, includes startup assistance when the plant is placed online, and continues with follow-up maintenance to ensure optimum operating performance of the plant.
