Hoisting of heat pump units for the 200,000-ton per year dimethyl carbonate production project at Shandong Xintai Depu Industrial Park

Thread Content

Recently, the installation of the 4 sets of heat pump units, which are the core equipment for the 200,000-ton per year dimethyl carbonate production project in the Depu Industrial Park of Shandong Xintai Yuanwang Park and for which Beijing Petrochemical Engineering Co., Ltd. served as the general contractor, was successfully completed. This has created favorable conditions for the subsequent construction of the process pipelines. This lifting operation is technically challenging and requires high safety standards. The compressor units feature a modular design. The project makes use of 300-ton class truck cranes for construction; each compressor weighs 97 tons in total, with the main unit itself weighing 40 tons. To ensure safe lifting, the project team conducted multiple rounds of analysis and optimization of the construction plan, thoroughly checked the preparations prior to lifting, and provided detailed technical instructions, ultimately achieving precise positioning. Currently, the project team is coordinating with the construction unit to carry out equipment leveling and calibration work, with secondary grouting expected to be completed within a week. With the completion of the compressor unit installation, the project officially enters the critical phase of process pipeline installation. To date, the process piping throughout the plant has had 150,000 inches of welding completed, representing a total progress rate of 55%. It is expected that the installation of all process piping will be finished by the end of July, thereby laying a solid foundation for subsequent system pressure testing and individual unit tests. This project is a key chemical industry upgrading initiative in Shandong Province. It employs internationally advanced transesterification technology, and upon completion, it will help meet the domestic demand for high-end carbonate products.
