According to Sinopec News Network (Dong Bo), on April 16, pile-driving work commenced for the supporting project of Tianjin Petrochemical’s refinery renovation – the construction of a new polypropylene plant with an annual production capacity of 200,000 tons. It is understood that the 200,000 tons per year polypropylene plant utilizes Sinopec’s third-generation loop reactor polypropylene process technology. This technology combines the newly developed asymmetric electron-donating agent technique with the propylene-butylene random copolymerization technique and second-generation ST technology to produce market-competitive asymmetric products and propylene-butylene copolymer grades. SEI provides the complete set of technologies and engineering design for this device, while the Beijing Research Institute of Chemical Technology supplies the catalysts as well as the production process packages for special new products. The facility is built within the premises of Tianjin Petrochemical’s Olefins Department; it is located on Tianjin Petrochemical’s own land, so no additional land acquisition is required. The required utility and auxiliary facilities are partially based on the existing facilities of the Olefins Department. The total investment is approximately 620 million yuan, with the goal of achieving a successful first operation by 2020. Once the facility is completed and put into operation, it will be able to handle the further processing of propylene produced as a result of the 15-million-ton oil refining expansion project, thereby enhancing the overall economic efficiency of Tianjin Petrochemical.
I used to work on the Tianjin Petrochemical project, which involved the construction of a plant capable of producing one million tons of ethylene and ten million tons of oil. Reading this news made me feel as if I were back to the time right after I graduated from university, when I was working on the ethylene project at Tianjin Petrochemical; it evoked nostalgic feelings, memories of my colleagues with whom I worked together back then.
It was about ten years ago, I think. The project I worked on just then is the one that stands out the most in my memory
Groundwork and civil construction began in 2007, and the oil refining and ethylene plants were put into operation for trial runs by the end of 2009; it was indeed a memorable experience when I first started working there.
