MOSCOW (MRC) -- China-based Hengli Petrochemical (Dalian) Refinery has awarded a contract to CB&I to use its Catofin catalytic dehydrogenation technology for a grassroots propane and butane dehydrogenation unit to be constructed in Dalian of Liaoning Province, as per Chemicals-technology.
Under the deal, CB&I will license and provide engineering design for the proposed dehydrogenation unit. As well as CB&I's Catofin technology, the unit will use Clariant's Catofin catalyst to process 300,000t per annum of propane and 600,000t per year of isobutane feedstock for jointly produce propylene and isobutylene.
The unit is claimed to be the largest single-train dehydrogenation plant in the world. CB&I technology operating group president Daniel McCarthy said: "CB&I's CATOFIN technology provides our customers with proven reliability and the flexibility to co-process multiple feed compositions at world-scale capacities.
"In addition to this award, CLG, CB&I's joint venture with Chevron, was awarded the ISODEWAXING catalytic isomerisation and ISOFINISHING hydrofinishing processes for this project. This multi-technology award underscores CB&I's broad portfolio of technology solutions."
CB&I's Catofin propane dehydrogenation process is a fixed-bed process that helps to produce propylene from propane commercially.
The company said that with the help of recently improved catalyst technology, the Catofin process has been able to accomplish highest conversion rate for propane dehydrogenation.
As MRC reported earlier, Hengli Petrochemical Company operates two PTA plants in Dalian with the total capacity of 4.4 million tpa. The company resumed operations at its PTA plant No. 2 with a capacity of 2.2 million tpa at the weekend, 20-21 October, 2012. Company"s PTA plant No. 1 with the capacity of 2.2 million tpa resumed production in September 2012. At present, the plant"s No. 1 capacity utilization is 80% of it total production capacity.
