Zhongyuan Dahuahua’s coal chemical plant achieves 200 days of Class A safe operation Author/Source: Zhongyuan Dahuahua Date: 2021-09-03 Clicks: 9 On September 3, good news came from Zhongyuan Dahuahua’s methanol division: the coal chemical plant has achieved 200 days of Class A safe operation, reaching the next milestone in terms of operational duration. This is the first time since the plant’s initial commissioning that it has maintained Class A status for 200 days. During this period, the daily methanol production reached a record high of 1,473 tons. Currently, the coal chemical plants are operating stably, moving toward higher goals. Since the beginning of this year, the Methanol Division has taken Party history learning and education as an opportunity to continuously promote the integration of Party building work with safe production. It has focused on both ensuring safe production and preventing the spread of diseases, fully implementing the \"three no’s and four possibles\" safety philosophy. The division has made steady progress in addressing challenges related to long-term operation, carrying out safety briefings and related corrective actions, as well as working on technical improvements to overcome difficulties, reduce costs and increase efficiency, and unlock the full potential of the production facilities. By managing abnormal conditions, conducting regular inspections and maintenance, and addressing leaks, it has continuously removed the obstacles that hinder the operation of these facilities, thereby addressing the key factors that restrict their long-term operation. Under the company’s arrangements, the Methanol Division conducted research and analysis based on practical issues such as the operating status of the plants, fluctuations in process parameters, and the effectiveness of operational procedures, making multiple adjustments to operating conditions in an attempt to increase methanol production. Through a series of measures such as the renovation of the S1201A heat-tracing pipeline, the optimization and upgrading of the air separation unit’s 85 generator set, efforts to improve the selection techniques for coal, and energy-saving renovations of the circulation water pumps, the economic efficiency of the plant’s operation has been significantly improved. At the same time, efforts are made to strengthen process discipline management, enforce strict control over process parameters, and enhance technical training as well as emergency drills ； Make strenuous efforts in controlling abnormal phenomena and preventing accidents to lay a solid foundation for long-term operation.
