The liquefied natural gas (LNG) plant has a lot of troubleshooting and upset conditions which appear during operating processing units for petroleum fields. These undesirable situations and obstacles have a great influence on plant performance and production. Therefore, the main objective of this paper is to identify LNG plant troubleshooting and determine its upset conditions. A full description for troubleshooting produced from operating plant units, which are not presented in operating manuals, is categorized. Additionally, the effect of upset conditions on each unit is presented. In order to solve these troubleshooting and disturbed situations, the best remedial and corrective actions are then proposed. The best operating practice is also suggested. A real case study of the LNG plant is done for the main 19 units of the plant: U01, U02, U07, U08, U12, U13, U14, U15, U16, U18, U51, U55, U56, U58, U63, U71, and U76. It is found that the effect of the upset condition are loss of electrical power, loss of instrument air, loss of gas feed, and troubleshooting. Most of the LNG units are suffering from disturbed conditions and troubleshooting during operation except U01, U02, U07, U65, and U71. [ABSTRACT FROM AUTHOR] |
