Hoisting of the access corridor for Shengxin Coking’s 1.6 million-ton coking project completed

Thread Content

On April 1, the upgrade project for Shengxin Coking Co., Ltd., a subsidiary of MCC Tian Gong Zhongyuan Company, aimed at increasing the capacity to 1.6 million tons per year with carbonization chambers 7.0 meters in height and top-loading coking technology, was completed successfully – all three corridors, namely M109 and 110 as well as the sixth span of M107 and 108, were lifted into place. This marks the full completion of the corridor-lifting tasks for this project. The total length of the coal preparation corridor for the Shengxin Coking Project is approximately 678 meters. The three corridors to be lifted this time are considered ultra-high-risk projects; the M109 and M110 corridors are each approximately 46 meters long, 3.8 meters wide, and 3.5 meters high, with a weight of around 68 tons, and the lifting height is about 55 meters ； The sixth span of the M107 and M108 corridors is 38.95 meters long, 7.6 meters wide, and 3.5 meters high; its weight is approximately 96.85 tons, and the lifting height required is around 57 meters. Due to the limited space around the corridor, the complex environment, numerous concurrent tasks, as well as the need for work at heights and the lifting of large equipment, the construction is extremely difficult. For this lifting operation, three cranes are used: 1 650T crane, 1 500T crane, and 1 300T crane. Before lifting operations in the corridor, thorough investigations were conducted multiple times of the access roads and the construction site; the capacity of these access roads was carefully assessed, the distribution of materials on site and the transportation requirements were thoroughly considered, and a detailed plan was made to determine whether road repairs were necessary. At the same time, repeated checks are carried out to ensure that there is no looseness in the wiring of the crane electrical equipment used in the operation, that the steel cables of the winching equipment are in good condition, and that the oil in the gaps between the steel cables is applied evenly. During the lifting process, the relevant responsible personnel monitored the operation throughout the time, coordinating everything as needed. Through close cooperation between the lifting supervisor and the crane operator, the lifting tasks of lifting, rotating, aligning, lowering, and adjusting were completed successfully. On October 3, 2023, the hoisting of corridor M119 for Shengxin Coking Co., Ltd.’s 1.6 million tons per year coking plant upgrade project, featuring carbonization chambers with a height of 7.0 meters and top-loading technology, was completed. This marked the successful finish of all corridor hoisting tasks for this project, laying a solid foundation for its timely completion. Project Name: Shengxin Coking Co., Ltd.’s 1.6 million tons/year coking facility with associated 200,000 tons/year methanol production and 60,000 tons/year synthetic ammonia production project
Constructor: Shengxin Coking Co., Ltd.
Location of Construction: Tangcheng Coal and Coking Deep Processing Park, Anze County
Nature of Construction: Technical upgrade
Scale of Construction: 1.6 million tons/year of dry coke production, 200,000 tons/year of methanol production, and 60,000 tons/year of synthetic ammonia production
Type of Furnace: 2×65-chamber JNX3-70-2 type top-loading coke ovens with a carbonization chamber height of 7.0 meters
Number of Employees Required: 585
Total Investment in the Project: 2,367,310,000 yuan
Total Land Area: 505,107 m2
Coking Production Process and Equipment Selection: The coking part of this project includes both coke production and gas purification; for coke production, 2×65-chamber JNX3-70-2 type single-heating top-loading coke ovens are used. For the dry quenching process, 2 sets of 180t/h dry quenching units will be installed, along with 2 x 24MW extraction steam turbines. Gas purification employs a process that includes condensation and blower technology, electrostatic tar capture, desulfurization using three series-connected towers, the use of sulfur foam and desulfurization waste liquid for acid production, ammonia removal via spray-type saturators, ammonia evaporation in ammonia evaporation towers, and final cooling followed by benzene extraction. Project background: Shengxin New Materials Co., Ltd. (hereinafter referred to as “Shengxin New Materials”) was established in November 2018. It is a subsidiary controlled by Shanxi Yongxin Coal Coking Co., Ltd., and is located in the Tangcheng Coal Coking Deep Processing Park in Anze County. In line with the development plan of Shanxi Yongxin Coal Coking Co., Ltd., and in order to better comply with relevant environmental protection policies at the national and provincial levels, enhance the scale of production capacity, improve the level of equipment used, increase the efficiency of equipment utilization and management, and reduce investment and energy consumption, Shengxin New Materials Co., Ltd. has decided to integrate the 600,000-ton coking capacity of Shanxi Taiyue Energy Co., Ltd., the 600,000-ton coking capacity of Shanxi Yongxin Coal Coking Co., Ltd., and the 650,000-ton coking capacity of Shanxi Linxin Coal Coking Co., Ltd. – of which 130,000 tons are to be used to help Shanxi Taiyue Energy Co., Ltd. reduce its excess production capacity while 520,000 tons are to be used for the construction of coking projects. This integration will enable the construction of a project with an annual coking capacity of 1.6 million tons, along with a production facility for 200,000 tons of methanol and 60,000 tons of synthetic ammonia, within the Tangcheng Coal Coking Deep Processing Park in Anze County.
