- Abstract
In order to explore the efficient restarting scheme of LNG plant under the premise of short-term shutdown, based on the actual production of a certain LNG plant in 2018, the reasons for the production suspension induced by various factors an; introduced, focusing on the micro-phase study of intermittent process(resumption of production) in the ease; of emergency repair under abnormal working conditions, normal production suspension and maintenance, fluctuation of raw material gas in the upstream and tight sales in the downstream. According to the research results, it takes 23 days for the whole plant to resume production from the cold state maintenance and transportation of complete shutdown to the normal discharge, which cannot meet the requirements of starting and stopping at any time under the new normal condition. Therefore, it is not competitive in the market. Under the premise of short-term shutdown, the production can be resumed in a safe and stable manner within 72 h with significant energy saving effect according to the regulations on thermal preparation for shutdown in the previous stage and the compact start and restart plan in the later stage. However, if technicians are too tired, there would be problems of post-startup extension caused by inconsistent start-up process and lack of key inspection items. Therefore, reasonable human resource; allocation should be paid attention to in the field work, and the study provides reference for the starting and resuming of process equipments in LNG plant.
