en.Wedoany.com Reported - China Guoneng Baotou Coal Chemical Co., Ltd. is advancing the Shenhua Baotou Coal-to-Olefins upgrade demonstration project in Baotou, Inner Mongolia. The core methanol synthesis stabilizer column for the project's second phase was recently hoisted into place. With a total investment of 17.15 billion yuan, the project's construction scale includes an annual production capacity of 2 million tons of methanol and 750,000 tons of polyolefins. Its goal is to establish a million-ton-class coal-to-olefins production line with full-process domestic technology.
The recently installed methanol synthesis stabilizer column stands 47.39 meters tall with a diameter of 4 meters, weighing 132 tons. As a key core component of the methanol synthesis process section, the column was positioned through coordinated efforts by the hoisting team. Its successful installation marks the transition of this production unit from the previous civil engineering foundation phase to the main equipment installation phase.
This demonstration project is classified as a major modern coal chemical project designated by China's National Development and Reform Commission and the Ministry of Industry and Information Technology. The project is an upgrade based on the world's first coal-to-olefins facility, which has been in operation for many years. The technical route employs a 2000-ton-class pulverized coal gasifier jointly developed by Kailin Energy and China Shenhua Coal-to-Liquid and Chemical Co. This gasification system possesses complete independent intellectual property rights and is the first in the industry to pilot the process of co-firing coal chemical wastewater with pulverized coal gasification.
Regarding supporting infrastructure and energy coupling, the project achieves deep integration of coal chemical production with green electricity, green hydrogen, and green oxygen. The second phase incorporates low-carbon energy into the production process by synchronously planning and constructing a new energy system. With the commencement of installation for large columns like the methanol synthesis stabilizer, the construction progress of the supporting pulverized coal gasification unit, methanol synthesis unit, and polyolefin plant for Phase II will be further aligned, paving the way for subsequent pipeline trestle installation and system integration and commissioning.
