The commissioning trial of the high-pressure flash gas recovery renovation project in the Methanol Department of Zhongtian Hechuang was a success on the first attempt!!! Author/Source: Zhongtian Hechuang Date: 2022-11-17 Clicks: 32 To ensure that the project was ready for commissioning, the Methanol Department took various measures to maintain quality and accelerate progress since the project was handed over. Without waiting or relying on others, taking proactive action – at the site of the high-pressure flash vapor recovery and renovation project, tasks such as polishing the fire protection pipelines, installing heating pipelines, and applying fireproof coatings are being carried out in an orderly manner. Even the chill of early winter cannot dampen everyone’s enthusiasm for working hard. Focusing on the overall schedule, careful organization was carried out. The team held several special discussion meetings to oversee the specific details of project completion, the progress of interlock testing for instruments and valves, the status of rectification efforts under the \"three inspections and four determinations\" approach, as well as the progress of construction work on fire protection pipelines and heat tracing pipelines. Strengthen management and make comprehensive plans; assign technical personnel to prepare job operation procedures, process technical specifications, alarm records, anti-freezing and anti-condensation plans, as well as production reports ； Training for all employees was strengthened; management staff provided detailed explanations to team members on the interlocks of the high-pressure flash vapor recovery system, the principles of compressors and their start-up and shutdown procedures, as well as the process flow and key operating points. After the training, quizzes were conducted to assess understanding of the interlocks and PID diagrams. Refine the objectives and tasks, and clarify the responsibilities to be fulfilled. By assigning specific personnel, defining the relevant pipelines, and identifying the blind flanges, each item is checked individually and confirmed with a signature. Detailed instructions are provided on the precautions and safety measures to be taken during the joint commissioning process; the commissioning plan is implemented item by item to further strengthen accountability. With meticulous attention and thorough effort, the joint commissioning of the high-pressure flash vapor recovery renovation project was completed with high quality. On the afternoon of November 15th and the morning of November 16th, Shu Haohua and Yi Zhi, the deputy general managers of the branch company, visited the site of the high-pressure flash vapor recovery renovation project to check the progress of preparations for the joint commissioning. At 9:17 a.m. on November 16, after the on-site personnel confirmed that the compressor oil station and water station were operating normally, they sequentially activated equipment such as the water wash tower, the separator at the top of the water wash tower, and the liquid discharge pump of the water wash tower; as a result, the air carrier was able to enter the high-flash-point recovery system successfully. When the compressor inlet pressure reached 0.5 MPa, Huang Shuhua, the deputy manager of the methanol department, started the compressor. Subsequently, on-site staff at the gasification unit divided into several groups to check the operation status of various equipment and carefully recorded all the operational parameters. After 1 hour of operation, all operational parameters were within normal ranges, indicating that the joint commissioning of the high-pressure flash vapor recovery renovation project in the methanol department was successful on the first attempt.
