In accordance with the overall plan of China Coal Hubei Energy Chemical Co., Ltd., on November 12, the company held a kick-off meeting for the performance evaluation of the technical renovation project aimed at increasing methanol production by 1 million tons per year. Company leaders, heads of various departments and centers, as well as representatives from process package suppliers, EPC contractors (including design and construction firms), supervision agencies, equipment manufacturers, and other relevant parties attended the meeting. The main task of this performance assessment is to conduct a comprehensive evaluation of whether the production capacity, process parameters, environmental protection metrics, product quality, equipment performance, level of automation, and consumption quotas of the methanol plant meet the design requirements. Ning Qiushi, the Party Committee secretary and executive director of the company, stated that performance assessment is a key task established at the beginning of the year. All units must work closely together and go all out. Strictly follow the \"Performance Assessment Plan\" to ensure the accuracy of the data. Third, 12 gasification furnaces are in operation at the gasification center, and the center needs to coordinate the personnel properly. Fourth, all units and functional departments must go to the field directly to carry out the methanol performance assessment work in a safe, proactive, and cautious manner. Fifth, everyone must unify their thinking and goals, and work together to complete the performance assessment. Cui Shuming, the company’s deputy general manager, made specific arrangements for this performance assessment, which is divided into three phases: the equipment preparation phase, the implementation phase, and the summary and report preparation phase. The following requirements are also put forward: First, it is necessary to strictly comply with the group’s performance assessment management methods, the company’s performance assessment plan, and the standards specified in the contract. Second, while carrying out performance evaluations for the methanol project, it is necessary to ensure the stable operation of the ammonia synthesis and urea production systems. Third, performance evaluation must adhere to a rigorous, meticulous, and practical work style to ensure that the device functions as intended and meets quality standards. Fourth, all necessary operations should be carried out and all required assessments should be conducted to ensure that each pump (including backup pumps) operates for more than 72 hours. Fifth, those involved in the performance assessment must fulfill their respective roles, be familiar with the \"Performance Assessment Plan\" and the relevant implementation standards, and ensure that standardized procedures are strictly followed throughout the assessment process. Sixth, it is necessary to conduct proper risk identification and assessment; ensuring safety is a prerequisite, and it is important to clarify the relationship between safety, load, and performance evaluation ; Seventh, it is necessary to comply with the unified coordination and command of the scheduling team, organize tasks carefully, and carry out operations meticulously to ensure that the performance assessment is completed safely, efficiently, and to high standards. The second-phase construction project of China Coal Enerchemical Company, aimed at upgrading the facility to produce 1 million tons of methanol per year through syngas production, is located in the Tuk Industrial Park in Ordos, Inner Mongolia. This project utilizes Zemach BGL fixed-bed slag gasification technology, purification techniques (low-temperature methanol washing + deep cryogenic methane separation), as well as advanced methanol synthesis methods that feature low consumption and low energy usage, in order to build a facility capable of producing 1 million tons of MTO-grade methanol per year. The project commenced construction on September 21, 2018. The Zhongmei Enechemical project, with an annual production capacity of 2 million tons of ammonia and 3.5 million tons of urea, was constructed in two phases. The first phase, which has an annual production capacity of 1 million tons of ammonia and 1.75 million tons of urea, includes two air separation units with a capacity of 40,000 Nm3/h each; these units were completed and put into operation in 2013. Meanwhile, some of the public facilities required for the second phase as well as all the office and living facilities have been built. Based on the market and operational conditions at that time, Phase II shifted from producing synthetic ammonia and urea to manufacturing 1 million tons of methanol, in order to supply MTO-grade methanol feedstock to the olefin plants of China Coal Mongolia Da Company.
