Reporters recently learned from Zhejiang Zhongkong Technology Co., Ltd. that the company has successfully won bids for several sub-projects related to the circular economy demonstration project at Yankuang Group’s Inner Mongolia Rongxin Chemical Co., Ltd., including those related to DCS/SIS/CCS systems as well as automated security and information management systems for an annual production capacity of 400,000 tons of coal-based ethylene glycol and 300,000 tons of polyoxymethylenemethane; contracts for these projects have been signed one after another. According to Ji Wenpu, general manager of Neirongxin Chemical Company, the project to produce 400,000 tons of coal-based ethylene glycol and 300,000 tons of polyoxymethylenemethane per year has been listed as a key project under Ordos City’s efforts to accelerate the development of a modern coal chemical industry demonstration base. The total budget investment is 7.68 billion yuan, with completion and operation planned for 2019. The designed capacity is 900,000 tons per year of methanol; 400,000 tons per year of coal-based ethylene glycol will be produced using the indirect method, with part of the methanol being used as a raw material to produce 300,000 tons per year of DMMn. The main construction elements of this project include 3 water-coal slurry gasifiers with a capacity of 4,000 tons per day each, and the coal feeding capacity per gasifier is the highest in the world currently ; Purification units such as CO conversion, low-temperature methanol washing, deep cryogenic CO separation, and PSA hydrogen production ; Process production facilities such as sulfur recovery, 900,000 tons/year of methanol, 400,000 tons/year of ethylene glycol, 300,000 tons/year of DMMn, 2×92,000 Nm3/h air separation units, 2×380 t/h high-pressure circulating fluidized bed boilers + 2×20 MW back-pressure steam turbine generators, as well as auxiliary equipment. Yu Haibin, vice president of Zhejiang Zhongkong Technology Company, told reporters that this project features numerous production units, a large system scale, complex processes, and significant control challenges. It is a modern large-scale coal chemical project that involves DCS, SIS, CCS systems, as well as automated security information systems, with over 37,000 I/O points. Automated security information systems include production and security video surveillance systems, access control systems, perimeter intrusion alarm systems, and intelligent inspection systems, providing an integrated framework platform for the construction of smart factories. Yu Haibin said that in this project, Zhongkong Company will achieve several \"*\": *a breakthrough in the use of ultra-large-scale water-coal slurry gasifiers capable of processing 4,000 tons of coal per day ; *Breakthrough in the application of 2×92,000 Nm3/h air separation units ; *Fully responsible for the entire control system of large-scale air separation plants, including DCS+SIS+CCS ; *Carry out projects to support the Mann turbine units, in order to achieve breakthroughs in imported unit projects. Ji Wenpu said that the total investment in the construction of this project is 7.681 billion yuan, of which 1.065 billion yuan is allocated to environmental protection measures; these environmental protection investments account for 13.04% of the total investment in the project’s construction. Based on the first phase of the Rongxin Chemicals project, the company will carry out further construction in phases two and three to extend the coal chemical industry chain. Ultimately, the goal is to achieve a production capacity of 5 million tons per year of methanol produced from coal, and to establish a demonstration base for a range of fine chemical products derived from coal, thereby creating a new benchmark for coal conversion and industrial upgrading.
In recent years, Zhejiang Zhongkong has achieved many breakthroughs; its market share has increased significantly, and its efforts in technology and product development have yielded notable results, making it a leading enterprise in the domestic control system industry.
