On September 17, the first large tower hoisting ceremony of the Tarim 1.2 million tons/year Phase II Ethylene Project of Dushanzi Petrochemical Company was held at the Shangku Petrochemical Park in Korla, Xinjiang.
As the first large tower, the quench water tower is the equipment with the largest diameter in the ethylene unit. It took only more than 100 days to complete the manufacturing, setting a record for the manufacturing of large oversized equipment. The main line of this hoisting used a 4,000-ton crane, and it took only 9 days to transport and assemble.
This hoisting marked the entry of the ethylene unit into the equipment installation stage, which kicked off the on-site construction.
The installation of the quenching water tower is the first large tower crane installation of the project, which opens the prelude to the installation of 9 large tower cranes in the entire ethylene unit. It is planned to complete the installation of 9 large tower cranes on October 31, marking a new stage in the construction of the ethylene unit project.
The main function of the cracking gas quenching water tower is to reduce the temperature of the cracking gas and recover low-grade heat at the same time. The cracking gas quenching water tower achieves cooling and partial condensation of the cracking gas through direct countercurrent contact with the quenching water. This process not only helps to reduce the temperature of the cracking gas and separate part of the gasoline in the cracking gas, but also recovers part of the low-grade heat through the quenching water cycle, further improving energy utilization efficiency. This series of operations effectively reduces the temperature of the cracking gas, ensures the normal operation of the cracking gas compressor, greatly reduces the amount of sewage discharged, and improves the energy utilization efficiency of the ethylene unit and reduces energy consumption by recovering low-grade heat.
At present, the overall progress of the project has been completed by 13.6%. It is planned to complete the construction of the underground pipeline network of the entire site on September 20 and the construction of the entire road on October 30. This year's interim goal is to complete 70% of the soil-less construction before the arrival of winter, creating good conditions for installation next year.
The total investment of the Dushanzi Petrochemical Tarim 1.2 million tons/year Phase II ethylene project is 21.88 billion yuan. After completion, it can produce more than 2 million tons of high-end polyolefins and high-performance rubber materials annually, further improving the localization rate of the domestic high-end petrochemical product industry chain supply chain. The basic machinery of the project is scheduled to be completed by the end of 2025, and fully completed and put into production in 2026.
