Author's Workplace:CNOOC Research Institute Co., Ltd.
Key Words:Slug catcher; Pig; Reconstruction; Finger slug; Vessel slug
Abstract:The pigging slug volume will increase to four times of the original design value due to oil condensate flow rate change after DF13-2 gas field is commissioned.Therefore, slug catcher can't meet to process the slug. Based on the existing process facilities, combined with the change of pigging slug volume of two onshore subsea pipelines and the design principle of slug catcher, the optimized innovation is studied.A new volume slug catcher will be built for LD pipeline, and a finger slug catcher will be built for DF pipeline.The existing DF and LD slug catcher will be changed to storage facilities for pigging slug liquid.The volume of new slug catcher will be reduced by two thirds, and the investment will save nearly twenty million for the project. The reconstruction plan will provide reference for other projects in the future.
