摘要

浮式液化天然气生产储卸装置（FLNG，又称LNG-FPSO）是一种用于海上天然气田开发的浮式生产装置。由于FLNG装置海上作业的特殊环境，FLNG液化工艺不仅要实现最基本的天然气液化功能，还需考虑海上恶劣的环境条件对FLNG液化工艺的影响。海洋中海浪的波动对液化系统中的关键设备——换热器影响较大。为了研究绕管式换热器在海上晃荡条件下的性能，通过建立双混合制冷剂液化工艺小试实验装置，进行绕管式换热器实验装置的晃动实验。结果表明实验装置晃动时，节流阀节流前压力降低，节流后压力升高，节流阀的节流效果变差，绕管式换热器换热效果变差。换热器的换热效果受到晃动的方向和FLNG中设备安装方向的耦合影响，倾斜工况下换热器换热效果受影响最大，受横摇影响较纵摇影响大。

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.
