| Deepwater floating production,storage and offloading unit natural gas(LNG-FPSO)technology can be flexibly configured according to offshore gas fields production status.It is economic security environmental protection and meets the needs of major oil and gas exploration in the country far from the sea.As a core equipment in pretreatment process,the operation status of the absorber has a significant impact on gas purification effect,gas quality and economic efficiency and offshore sloshing conditions for the absorber expands requirements.Researching on the influence of the ocean sloshing on absorber liquid distributor,packing section,etal and making optimization recommendations is significant to maintain efficient deacidification.In this paper,research work for the absorber liquid distributor,packing section by sloshing impact conditions and make recommendations based on the findings.According to the experimental requirements,design and build a set of experimental device,and the device enables the performance study of the groove liquid distributor,tube liquid distributor,random packing,structured packing under the static and sloshing conditions.This artical established a groove liquid distributor,tube liquid distributor,random packing,structured packing numerical model,conducted a grid independence and verified the accuracy of the model.According to the law of similarity to determine the conditions studied using sloshing 6 °,cycle 10 s.Flow field research carried out by the method of numerical calculation of groove liquid distributor,pipe-type liquid distributor,random packing and structured packing;Using amine deacidification pilot experimental device studied packing support plate.According to the flow field changes within the absorber internals under sloshing conditions,Proposed optimizations to adapt the ocean sloshing conditions.Research work in this paper provide a reference for the FLNG absorber simulation,experimental studies and engineering design ofthe inner parts. |
