Progress on the Construction of the HuiNeng Coal-to-Natural Gas Project in Inner Mongolia Author/Source: Huahua Network – Coal Chemical Industry Date: 2020-08-07 Clicks: 7 Recently, the HuiNeng project team of the Northwest Branch of China National Chemical Engineering Corporation Sixth Construction Co., Ltd. successfully completed the installation of the fifth section of the wash tower for the T1601 shift gas. Thus, the T1601 shift gas scrubber, with a single-unit weight of 1,658 tons and a height of 85.6 meters, has finally been fully installed in place. The Inner Mongolia HuiNeng coal-to-natural gas project is located in the Shengyuan Coal Chemical Industry Base in Yijinhuoluo Banner, Ordos City. It uses coal as raw material to produce synthetic natural gas and liquefied natural gas, and it is the first coal-to-natural gas demonstration project in China to be invested and built by a private enterprise. The second-phase natural gas liquefaction project (LNG) is a load-driven natural gas liquefaction plant. The planned investment for this project is 12 billion yuan; the construction will include natural gas purification, liquefaction, storage of liquefied natural gas, water supply and drainage systems, transportation facilities, as well as related supporting infrastructure. It will enable an additional production capacity of 1.6 billion cubic meters of coal-derived natural gas, all of which will be liquefied. The plant will be able to process 2.7 million Nm3 of natural gas per day, with operation expected to begin in 2021. The HuiNeng Project Department of the Northwest Branch of China National Chemical Engineering Corporation Sixth Construction Co., Ltd. is responsible for the purification and water supply and drainage tasks. In the installation projects undertaken by the HuiNeng Project Department, there are a total of 598 pieces of equipment; 18 of these are equipped with a weight of over 100 tons, 5 have a weight of over 300 tons, and 4 have a height of over 50 meters. The most challenging among them is the T1601 transformed gas scrubber tower; this tower has a total net weight of 1,658 tons and a total height of 85.6 meters, making it a project of considerable scale with high risks. To this end, the project department took into account the overall site conditions and the characteristics of the equipment, as well as various factors such as safety, quality, economics, and environmental conditions, and formulated a corresponding specialized plan which was then reviewed by experts as required. It was finally decided that the equipment would arrive in five sections, to be lifted section by section from bottom to top, with vertical joint welding carried out in the air. At present, the HuiNeng project team is in a critical phase of the project: approximately 350,000 yuan worth of work related to welding pipe joints and the installation of 490 pieces of equipment must be completed by October 30, 2020, meaning there is a tight deadline and a heavy workload. The successful lifting of the T1601 transformed gas scrubber marks a phased victory in the project’s struggle to overcome challenges.
