LNG加 加 气站供销差产生原因分析与管控.

Objective The supply and sales difference has always been a key point in the management and control of LNG filling stations. Reducing the supply and sales difference of LNG filling stations, especially inefficient LNG filling stations, is of great significance for cost control. Methods According to the actual production and operation status of the station, the specific reasons for the supply and sales difference of LNG filling stations are comprehensively analyzed from the aspects of sales measurement, trade procurement, unloading process and storage. For some factors that enlarging supply and sales difference, the targeted control measures shall be taken from the aspects of gas source procurement, process pipeline design, thermal insulation construction, submersible pump installation, tank release control and station construction mode, etc. Results Through the measurement of practical data after the process transformation and the refined management of production and operation, the supply and sales difference of LNG filling stations has been effectively reduced. Conclusions In the initial design stage and actual operation and management stage of LNG filling stations, we should confirm the station construction standard and strengthen the management and control of LNG filling stations to reduce supply and sales difference according to characteristics of LNG properties, so as to improve the profit of LNG filling stations.
