On April 3, good news came from the construction site of the energy-saving and environmental-protection upgrade project for Shanxi Cauliflower Coal Chemical Industry. The shell of the synthesis tower in the ammonia synthesis unit area, lifted by the sixth lifting command post of Sinochem Second Construction Heavy Machinery Company, was positioned accurately and smoothly. It is reported that the equipment has a diameter of 2.8 meters, a height of 31 meters, and a weight of 407 tons. Its lifting was accomplished through the coordinated efforts of two cranes: a 1600-ton crawler crane with an 84-meter main boom, a working radius of 20 meters, and a 450-ton superlifting counterweight, and a 500-ton crawler crane with a 60-meter main boom, a working radius of 13 meters, and a 50-ton superlifting counterweight. The successful lift marked the completion of the construction tasks involving this 1600-ton crawler crane. The Shanxi Cauliflower Coal Chemical Industry Energy-Saving, Environmentally Friendly Upgrade Project involves the renovation and expansion of an existing urea production facility, as well as a technical upgrade to achieve zero wastewater discharge. This project makes use of pressurized continuous gasification technology for coal particles/blocks, with 5 new continuous gasifiers being installed to replace the existing 37 batch gasifiers; the total investment amounts to approximately 3.962 billion yuan. The completion of this project will effectively reduce energy consumption, lower emissions, and improve the ecological environment, thereby injecting green momentum into the high-quality development of the region.
