Shenhua’s coal chemical project worth over 100 billion yuan reaches a key milestone Author/Source: Coal Chemical Industry 114 Forum Date: June 10, 2020 Clicks: 8 After days of intensive and organized work, on June 4, all the transformers and high/low voltage switchgear in the gasification unit’s substation of Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project (Phase I) were successfully powered up, with all systems operating normally. This marks a successful one-time power-up of the gasification unit’s substation! The substation serves as the power hub of the gasification plant, responsible for supplying electricity to the various electrical loads within the plant. Its installation and commissioning require a tight schedule and significant effort, and it also has to deal with the various uncertainties brought about by the COVID-19 pandemic. The project department of Tianchen Company responded proactively, planned meticulously, and fulfilled its responsibilities and obligations through concrete actions. On the eve of this year’s Spring Festival, a large number of low-voltage switchgear units arrived at the site, resulting in a heavy workload for installation and wiring. To ensure that all these switchgear cabinets could spend the New Year in the substation, the project team developed a specialized installation plan, urging the installation contractors to prepare sufficient human and mechanical resources in advance, thereby completing the installation of the cabinets at the site within a short period of time. Power supply systems such as EPS and UPS in the substation are supplied by manufacturers in Wuhan, Hubei. Due to the impact of the pandemic, there are significant difficulties in equipment production and logistics transportation. The project procurement department took proactive action; it communicated with the manufacturers on multiple occasions through various means such as video calls and phone calls, demanding that they ensure timely delivery of the goods. It also assisted the manufacturers with the transportation of the equipment and with implementing measures for epidemic prevention throughout the process, so as to ensure that the power supply equipment arrived at the project site as quickly as possible. To ensure that the substation received power on time, the project team members put the overall interests first, voluntarily gave up their rest time, and adopted a \"day and night\" working schedule. The constant stream of messages in the work WeChat group are the most pleasant sounds, and they represent one of the manifestations of the enthusiastic atmosphere surrounding the \"60-Day Intensive Work\" campaign. As a key milestone in the contract, the successful power connection to the gasification substation on schedule has created favorable conditions for the subsequent single-unit testing, instrument calibration, and furnace drying, which is of great significance for advancing the overall progress of the gasification facility. The first-phase project of the Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project is a preliminary phase of this project (CTC Project). It also serves as a facility for producing methanol raw materials to support the already completed Shenhua Shaanxi Methanol Downstream Processing Project (SSMTO). With a total investment of 13.6 billion yuan, the construction includes an annual production capacity of 1.8 million tons of methanol along with 400,000 tons of ethylene glycol per year. The facility comprises various process units such as air separation, gasification, shift reaction, acid gas removal, methanol synthesis, sulfur recovery, and ethylene glycol production, along with the necessary utility systems and auxiliary facilities. Once completed, it will enable integrated production and management with the SSMTO project. It is reported that General Electric (GE)’s high-cooling, efficient water-coal slurry gasification technology has been selected for the project in order to promote the clean, comprehensive, and efficient utilization of coal. The project utilizes 5 gasification furnaces of the single-series type, with a coal feeding rate of 3,100 tons per day on a dry basis, operating in a slurry-cooled process; the pressure level is 6.5 MPa. These furnaces are equipped to produce 1.8 million tons of methanol per year (for olefin production), as well as 400,000 tons of ethylene glycol and other high-value downstream products. Methanol synthesis uses the David technology, while ethylene glycol employs the Shanghai Pujing technology. The Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project (hereinafter referred to as the CTC Project) was officially approved by the **National Development and Reform Commission on March 16, 2015 (Document No. FGNY [2015] 508). The total investment in the project amounts to 120 billion yuan.
