This is just a starting point; more participation will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the forum discussions and exchanges. ********************************************* The total investment in the Sanjiang Chemical Project exceeds 10 billion yuan. The project includes the construction of a new 1.25 million tons per year hydrocarbon utilization facility (i.e., an ethylene cracking unit), a 30,000 Nm3/h air separation unit, a 1 million tons per year EO/EG (i.e., ethylene oxide and ethylene glycol) production facility, as well as various supporting utilities and safety/environmental protection systems. The main facilities of this project cover an area of about 320,000 square meters, with completion scheduled for August 2021. It is understood that both main units of this ethylene project incorporate world-class patented technologies currently available on the international market. The lifting of the convection section module for the ethylene cracking furnace in the 1.25 million tons/year light hydrocarbon utilization unit is a critical task in the construction of the cracking furnace. Faced with challenges such as hot weather, limited space, and tight deadlines, the Sanjiang project team of the construction contractor, in collaboration with Shanghai Zhuoran, continuously improved the lifting plan for the convection section modules of the 7 pyrolysis furnaces. This approach helped to overcome various difficulties related to transportation and lifting, safety management, quality control, and improving work efficiency during the modular construction process, ensuring that the modular construction of the pyrolysis furnaces proceeded safely, efficiently, and to a high standard. The project department carries out strict oversight of the lifting operations, conducting comprehensive and thorough inspections to identify potential safety risks, ensuring that each convective section module is installed in one lift. On the morning of June 24, 2021, the first lifting of the cracking furnace module for the Sanjiang Chemical Project was successfully completed. On the afternoon of July 21, the ethylene cracking furnace of Sanjiang Chemical’s 1.25 million tons/year light hydrocarbon utilization facility saw the completion of the installation work for all 53 convection section modules, as the last such module was lifted into place. This marked the successful completion of the installation process, which involved 28 days of continuous work. It created favorable conditions for the subsequent construction of the cracking furnace’s steel structural framework and process pipelines.
