Shenhua Ningxia Coal Industry Group’s Coal-to-Oil Division makes every effort to succeed in the project’s commissioning process. Author/Source: Date: 2016-09-06 Clicks: 12. Given the challenges associated with large-scale projects, numerous processes, long production chains, high integration difficulties, a high degree of domestic component use, and the lack of existing experience to draw from, Shenhua Ningxia Coal Industry Group’s Coal-to-Oil Division adheres to strict control standards. Through careful organization, management, operation, and maintenance, it strives to overcome the difficulties involved in project commissioning and ensure everything proceeds without issues. Well-organized. The company schedules tasks based on the internal control testing milestones, reverses the timeline, strengthens the linkage between the testing plan and the project plan, and accelerates the completion of the project and the handover of responsibilities ； Strictly implement the linked assessment mechanism, enforce strict controls and severe penalties for issues at milestone stages as well as those on the production side, in order to enhance the seriousness of production preparation and commissioning work. Strictly implement the standardized commissioning work packages, reinforce the adherence to process specifications, conduct systematic checks on design aspects and remaining engineering tasks to identify equipment quality issues. Formulate targeted action plans based on the commissioning sequence, and urge the construction party to intensify efforts to address these issues. While ensuring safety and quality, further optimize the commissioning strategies and plans to ensure that key bottlenecks in the commissioning process are resolved on schedule. Carefully managed. The company implemented the 24 rejection criteria for commissioning operations set by the group company, and formulated 82 specific measures for such commissioning processes. It adhered strictly to the principles of \"no deviations in procedures, no omission of steps, and no lowering of standards\" in carrying out these tasks ； Organize personnel to conduct thorough inspections for missing design elements, as well as for quality issues and potential hazards in the project. For the problems identified in areas such as project design, procurement, construction, processes, and instrumentation, timely corrective actions are taken by assigning specific tasks, personnel, deadlines, and measures ； Strictly enforce the procedures for rectification inspection and acceptance by CCCC, and resolutely prevent the acceptance of projects that do not meet the standards. Operate with care. In line with the strict requirements for equipment commissioning, and to ensure that the commissioning of each unit is successful on the first attempt, the project construction command center plays a key role in production supervision and overall coordination, thereby strengthening the oversight, control, and coordination throughout the entire production commissioning process ； The engineering and technical personnel as well as experts from the preparatory team conducted in-depth reviews of the commissioning plans at the plant (center) and branch company levels, continuously optimizing and refining the overall commissioning plan, the analysis of startup strategies for the two production lines along with the isolation plans, as well as the commissioning plans for each unit ； All test engineers and operators consistently adhere to the principles of \"conducting individual unit tests early, ensuring strict airtightness during purging, carrying out comprehensive joint tests, proceeding with material feeding tests in a steady manner, having optimal test plans, and keeping test costs low\", thereby carrying out thorough system debugging and operation. Meticulously maintained. On the one hand, building on the 37 technical demonstration plans that have already been developed, in collaboration with research institutions, the project is focusing on key issues such as coal powder leakage, a stable control system for the electrical system’s island operation across the entire plant, overall interlock systems, and independent operation modes for Oil Lines A and B, conducting research on these topics and formulating and implementing measures to address major risks. On the other hand, all construction workers, supervisors, and commissioning personnel are organized to strictly adhere to construction standards, technical standards, management standards, and quality standards. Thorough and rigorous inspections and verifications are carried out on the safety of the process systems and the reliability of the instrument interlock logic, to ensure that the integrity rate of instrument equipment reaches 100%, its utilization rate reaches 100%, and the level of automatic control reaches 90%, with instrument testing achieving sensitivity, stability, and accuracy ； The utilization rate of the primary interlock system reached 100%, while that of the secondary interlock system reached 98%; the interlock system proved to be sensitive and reliable.
The 4 million tons per year coal-to-oil project in Ningxia began trial operation on October 1. Author/Source: Date: 2016-09-06 Clicks: 14 On September 1, Shenhua Ningmei Group’s 4 million tons per year coal-to-oil project held a handover ceremony for Unit 1 & 3 of the gasification facilities, Unit 4 of the syngas purification system, Area 2 for oil processing, as well as the sulfur recovery and related flare systems. Ensure that the methanol line and Product A line are put into operation for trial runs on schedule. Among them, Series 1 and Series 3 of the gasification units have been successfully delivered, marking the transition of work on these two series from the construction phase to the production testing phase. It is reported that the project team will carry out trials for feeding materials into the gasification units on October 1st. Meanwhile, the project plans to start trial operations of the methanol line on October 15, and trial operations of oil product Line A on November 15, with the entire process to be operational by the end of the year, enabling the production of qualified oil products. To date, all pipeline modifications for the gasification series of LPG (liquefied petroleum gas) production units have been successfully completed. All the water-conveyance systems in the two series have been connected, and the pneumatic conveying system pipelines for lines 17# and 18# in the coal preparation unit of Series 3 have passed the airtightness tests. On August 25, the unit test of the nitrogen compressor in Series 3 of the gasification unit for Shenhua Ningmei Group’s 4 million tons per year coal-to-oil project was successfully completed. The success of this test run marks the readiness to proceed with the heating and sulfidation processes for the converter and the detoxification tank, thereby preparing the converter for gas feeding during the commissioning trial on October 1.
What is the current production capacity in terms of million tons per year for coal-to-oil production at Yankuang?
I heard from others that China has plenty of coal but little oil, which is why coal is used to produce oil. This process is also forced to be adopted; it is costly, and many key pieces of equipment still rely on pure imports. Daring to innovate and dare to challenge is praiseworthy!
When I left the company in May, the load was not high; details can be discussed via private message.
