Wishing everyone a happy New Year, and peace, health, and happiness for their families. I’m just offering my thoughts; more participation from everyone will make things more lively. Haichuan becomes even better with you all here; feel free to engage more in discussions on this forum. ------------------------------------------------------------------The adaptive renovation project for distillation units is one of the key projects during Jinxī Petrochemical’s major maintenance efforts in 2020. Due to the device having been in operation for many years, the existing technology is unable to meet the raw material requirements of the surrounding devices. As required by the design specifications, significant technical modifications are needed for the entire installation; aside from retaining some of the equipment in the atmospheric pressure furnace and reduced pressure furnace, all other frames, equipment, associated pipelines, as well as the foundations will be removed and rebuilt. The plant structure weighs over 2,000 tons, the platform weighs over 180 tons; there are 219 pieces of equipment, more than 40 kilometers of pipelines, over 5,600 valves, and more than 15,860 flanges. Using the conventional construction methods, it would take at least 5 months, but taking all factors into consideration, Jinxī Petrochemical requires that the project be completed in just 3 months. After the construction contractor, CNPC No.7 Construction Company, conducted repeated on-site inspections, studied the blueprints and construction examples, and held brainstorming sessions, it ultimately proposed boldly to increase the prefabrication depth to the maximum and to carry out construction in a \"modular\" manner – that is, dividing the installation into different modules, completing tasks such as constructing structural platforms, installing equipment, laying process pipelines, and installing electrical and instrumentation systems within each module, and finally assembling these modules together like building blocks.
