Recently, the last large-scale equipment for the Tianchen-Guizhou Energy Shuicheng 2 million tons per year circular economy comprehensive utilization coal coking project – the waste heat boiler E3102 – was successfully installed, marking the completion of the installation of all large-scale equipment for this project. The installation of all large-scale equipment for the coal gas to natural gas project in Guizhou’s Energy and Water City circular economy comprehensive utilization project has been completed.

As a key component of Guizhou Energy Group’s Shuicheng District \"coal-coke-chemicals-electricity\" circular economy base, this project represents an important implementation of Guizhou Province’s strategy of making optimal use of its rich mineral resources. In line with a 12-month construction timeline, this project utilizes internationally advanced chemical processing technologies. Through processes such as the compression of coke oven gas, pre-purification, and advanced desulfurization, it transforms by-products from the traditional coking industry into clean energy in the form of natural gas, thereby enabling the extension of the industrial chain and an improvement in the value chain. Once in operation, the project will be capable of processing 55,000 standard cubic meters of coke oven gas per hour, yielding approximately 186 million standard cubic meters of natural gas annually, thereby contributing to the optimization of Guizhou Province’s energy structure and the development of its industrial sector. The waste heat boiler E3102 that was lifted this time weighs 39.823 tons, has a diameter of 1.5 meters, and a length of 13.713 meters. Faced with complex on-site working conditions and high-precision installation requirements, the project team from Sinochem Sanhua Construction established a specialized technical team to accurately calculate the crane’s swing radius and positioning parameters, and worked together with the supervision unit to conduct a thorough inspection of the lifting gear. After completing the safety technical briefing for the lifting operation, the on-site supervisor precisely coordinated the two cranes to work together. As the main hook head descended slowly, the waste heat boiler E3102 was successfully lifted into place. The successful completion of this critical milestone fully demonstrated China Chemical Sanhua Construction’s professional expertise and technical advantages in the lifting of oversized equipment, earning high praise from the project owner and supervision agency, and highlighting its capability to provide end-to-end services in the advanced coal chemical industry.
