Yuenenghua’s methanol synthesis catalysts produce another record amount of methanol Author/Source: Yuenenghua Date: 2021-07-14 Clicks: 34 The methanol production volume generated by the second synthesis catalyst in the first line of the methanol production facility reached 6.266 million tons, surpassing the previous record set by the first catalyst, which produced 6.264 million tons of methanol. ” On July 13, the person in charge of the methanol production unit at Yulin Energy Chemical Company said that as of 8 a.m. that day, the second catalyst unit had been in operation for 35 months since its deployment in July 2018; methanol production levels had reached new heights, and the performance of this facility ranked among the best among similar facilities in China. It is reported that the methanol synthesis unit at Yulin Energy Chemical utilizes the advantages of comprehensive utilization of coal, oil, and gas resources; through \"hydrocarbon complementarity,\" it effectively overcomes the shortcomings of traditional coal-based methanol production, which features high carbon content and low hydrogen content, as well as those of natural gas-based methanol production, which has high hydrogen content and low carbon content. Compared to conventional coal-based methanol plants, this facility can reduce carbon dioxide emissions by over 3 million tons per year; moreover, thanks to its optimal operating conditions, the catalyst remains more stable during production. At present, the amount of methanol produced by the second catalyst furnace has far exceeded the designed output by over 800,000 tons. It is understood that since the catalyst for the second methanol synthesis unit at Yulin Energy Chemical was put into use, the methanol production facility has continued to strengthen the basic management of production operations, actively carried out technical upgrades and research efforts, and successively resolved issues such as high vibration levels in the exhaust fans of the conversion unit, high load on the fine slag filters in the gasification unit, and severe wear on the quenching rings. As a result, the rate of stable operation of the units reached over 99.9%. At the same time, the center has been continuously strengthening the identification and resolution of potential hazards, as well as staff training; as a result, the level of production, operation, and management of the equipment has improved, and the energy consumption per unit of methanol raw material has been significantly reduced to 33.5 GJ. Since the beginning of this year, in light of the fact that the catalysts had reached the end of their operational life, Yueneng Chemical Company has organized the Methanol Center and relevant technical departments to hold timely discussions with the catalyst manufacturers, thereby formulating a scientific, reasonable, and reliable plan for operating the catalysts at the end of their lifespan. Technicians collect operational data on a daily basis; by closely monitoring and analyzing parameters such as carbon conversion rate, fresh gas consumption per unit volume, and catalyst bed temperature, and by making timely adjustments to the operating parameters, they ensure the efficient and stable operation of the catalyst. The person in charge of the methanol unit said that operational data show that the synthesis catalyst in this furnace is still functioning well. In the future, more attention will be paid to monitoring the catalyst’s activity; employees will be instructed to operate it carefully, and efforts will be made to ensure safe and stable operation. By continuously improving operational performance, it is possible to maximize efficiency and contribute to achieving the company’s annual goals.
