FLNG绕管式换热器晃动实验分析
Experimental study on effect of sloshing on performance of heat exchanger
摘要
Abstract
Floating LNG production storage and offloading unit (FLNG, also known as LNG-FPSO) is a kind of floating production device for offshore gas field development. The natural gas liquefaction process is a core technology of FLNG, which has a huge impact on the safety, stability and costs of the equipment. Because of the special conditions of offshore operations, FLNG liquefaction process is required not only to achieve the most basic functions of liquefaction, it is also expected to overcome the interference of various constraints. In order to research the performance of the coil wound heat exchanger under sloshing conditions at sea, an experimental device of dual mixed refrigerant liquefaction processes is established and the sloshing experiment of coil wound heat exchanger is carried. The results show that: when the experimental device is under sloshing conditions, pressure reduces before throttle valve and increases after the throttle valve, the performance of throttle valve and coil wound heat exchanger becomes worse.关键词
