[Abstract]:Deep-sea floating gas production storage and unloading (LNG-FPSO) technology can be configured flexibly according to the production conditions of offshore gas fields. It can save transportation cost, and does not occupy onshore space, so it is safe and environmentally friendly. To meet the country's offshore oil and gas extraction major demand. Absorption tower is the core equipment of pretreatment process on FLNG. Its operation condition has great influence on gas purification effect, gas quality and its economic benefit. Especially, the adaptability of absorption tower is required under special sloshing conditions on the sea. It is of great significance to study the influence of ocean sloshing on the important parts of absorber such as liquid distributor and packing section and to improve the decarburization efficiency of absorber under sea sloshing condition. In this paper, the influence of sloshing on the structure of liquid distributor, packing section and other important absorption tower structures is studied, and the structural optimization of the inner parts of the tower is carried out according to the results of the study. According to the experimental requirements, a set of cold model experimental device for amine decarbonization absorption tower under sloshing condition is designed and built. The device can realize the design of tank liquid distributor, row tube liquid distributor and bulk packing according to the requirements of the experiment. Study on the performance of uniform packing column under static and sloshing conditions. The numerical calculation models of slot liquid distributor, tubular liquid distributor, bulk packing and regular packing are established. The mesh independence is verified and the accuracy of the model is verified by experimental data. In this paper, the flow field of slot liquid distributor, row tube liquid distributor, bulk packing and regular packing under sloshing condition is studied by using numerical calculation method in the sloshing condition with amplitude 6 擄and cycle 10 s. In this paper, the optimization of packing support plate was studied by means of a pilot plant for amine decarbonization. According to the variation of the internal flow field in the carbon absorption tower with amine method under sloshing conditions, the optimization of ocean sloshing conditions was studied respectively. The research work in this paper provides a reference for the simulation, experimental research and engineering design of absorption tower structure on FLNG.
