摘要

增压-冷凝系统是LNG接收站的控制核心。介绍了增压-冷凝系统工艺流程

结合某LNG接收站运行过程中高压输送泵入口过滤器阻塞的情况分析了高压输送泵入口压力与过滤器压差间的变化规律以及在此情况下泵井放空管线配管对再冷凝器平稳运行的影响

对存在的问题提出了优化方案

从而保证增压-冷凝系统稳定运行。

Abstract

Stable operation of booster-recondensation system is critical for liquefied natural gas(LNG)receiving terminal.This paper illustrates the process and control scheme of Booster-Recondensation System.Based on the high-pressure pump inlet filter blocking scenario

paper discussed the interaction between high-pressure pump suction pressure and the filter pressure difference.Meanwhile paper demonstrates the potential impact to recondenser operation due to pump well vent line piping design.Optimization is proposed for stable operation.
