The hydrogenation catalyst used in Yongjin’s ethylene glycol production facility in the Puyang industrial park has achieved a new record in terms of tonnage produced per unit of catalyst, according to industry sources. Author/Source: Henan Zhongyuan Dahuahua Group Co., Ltd.; Date: 3-18-2020; Clicks: 48. It was reported recently that since the copper-based catalysts in this facility were put into use on April 3, 2018, they have operated for a total of 14,150 hours as of March 16, during which time 263,153 tons of ethylene glycol were produced. This means that each unit of catalyst generated 2,530 tons of ethylene glycol, setting a new record for hydrogenation catalyst efficiency in the coal-based ethylene glycol production industry. Yongjin Company makes full use of its management and professional strengths to strengthen oversight in areas such as process optimization, employee skill development, and plant operation evaluation, thereby laying the foundation for high and stable production levels of the plants. First, continuously optimize process operations. To address the problems and bottlenecks in production, the company organized specialists from the process, equipment, and electrical and instrumentation fields to develop detailed solutions and optimization measures, as well as contingency plans for handling abnormal situations, thereby ensuring the stable and safe operation of the facilities. Second, continuously improve employees’ operational skills. Position engineers use training methods such as on-site explanations, hands-on operations at the control panel, and case analyses to enhance the personnel’s understanding and ability to operate the entire system. Third, continue to ensure the proper maintenance of key equipment. Strengthen the inspection of key equipment on-site, manage backup units properly, and ensure 24/7 monitoring and support for maintenance tasks. Fourth, continue to conduct proper operational evaluations of the catalysts. Continue to carry out daily statistics, weekly summaries, and monthly evaluations to keep the catalyst in its optimal operating condition at all times.
