【Haichuan Petrochemical Project Updates】Total production capacity rises to 780,000 tons per year! The second-phase propane industry chain project of Lianyungang Sierbang Petrochemical has achieved completion

Since the commissioning of Sierbang’s first production facility in 2016, it has become a key supplier in China’s acrylonitrile industry. With the operation of this new facility, Sierbang Petrochemical’s position in this industry will be further strengthened, and it will also help to fill the gaps in the domestic market. The equipment supplied by CCCC this time is the third acrylonitrile production unit for Srbon Petrochemicals. Once this unit is put into operation at full capacity, together with the existing production capacity of 520,000 tons per year, the company’s total production capacity will rise to 780,000 tons per year, making it the largest in China. The project involved welding 1.28 million inches of pipeline, installing over 2,000 pieces of dynamic and static equipment, and constructing/manufacturing steel structures weighing around 22,000 tons. At its peak, there were 3,500 construction workers here.

The project covers an area of approximately 700,000 square meters and mainly includes facilities such as propane dehydrogenation (PDH), acrylonitrile production, air separation and compression systems, as well as wastewater treatment systems. The company’s scope of supervision includes the renovation of the acrylonitrile plant, the methyl methacrylate plant, and the SAR2 plant under aerobic operating conditions. PHC-500(125)AB-C80 prestressed concrete pipe piles will be used for the pile foundation; the length of each pile is 35 meters. A total of around 2,800 sets of piles are required, and the construction of these piles is expected to be completed by the end of August 2020.

The T-3001 recovery tower is the core equipment of the refining unit in the acrylonitrile plant. It is 69 meters tall and weighs 367 tons. It was manufactured by Zhanghua Machinery (Suzhou) Heavy Equipment Installation Co., Ltd., transported by Sinotrans Heavy Cargo Logistics Co., Ltd., and lifted into place by Sinopec Fifth Construction Co., Ltd.
