The purging of all the process pipelines at the 600,000-ton methanol plant in Xin’ao (Daqi) officially began at 16:10 on February 11; the low-pressure nitrogen main lines, the shift reactor, the low-temperature methanol washing unit, the distillation units, the tank areas, the sulfur recovery system, and the fuel gas network were all purged one after another. To buy time and ensure the smooth progress of purging, temporary pipes were used to connect the compressed air from the air compressor to the low-pressure nitrogen pipeline; taking advantage of the fact that the low-pressure nitrogen pipeline covers the entire plant, the air was directed to various areas for purging. To date, 294 out of the 424 purging points in the entire plant have been purged, accounting for 69% of the total workload. The conversion and methanol distillation units were completed on the 21st; 80% of the low-temperature methanol washing process has been finished. Purging of the methanol synthesis and sulfur recovery units is scheduled to begin on the 24th. The process pipelines throughout the plant serve as the backbone of chemical production. Pipeline purging involves using air to remove debris such as slag from within the pipelines; it is an important and essential task during the chemical plant’s commissioning phase, ensuring the proper functioning of instruments, valves, and meters, as well as the proper operation of equipment and compressors. At present, the purging work is progressing smoothly as planned, and it is expected to be completed by March 5, laying a solid foundation for this year’s chemical plant commissioning trials. .
