LNG接收站与电厂取排水一体化设计的探讨

Discussion on the LNG Receiving Station and Power Plant Water Intake and Drainage Integrated Design

液化天然气(liquefied natural gas,LNG)接收站利用大量的海水将液化天然气进行气化,热交换后海水变成冷排水回归大海,其取水排水是一个降温过程;电厂利用海水作为电厂汽轮机排汽冷凝用冷源,使乏汽冷凝成凝结水,热交换后海水变成温排水回归大海,其取水排水是一个升温过程。对LNG接收站和电厂取排水二者的一体化设计进行探讨,并对电厂利用LNG接收站冷排水所产生的收益进行分析。

LNG receiving station uses a large amount of seawater to reduce LNG for gasification,after heat exchange,seawater turns into cold drainage and returns to the sea,this is a cooling process;Power plants use seawater as a cooling source for steam turbine condensate,after heat exchange,seawater turns into warm water and returns to the sea,this is a heating process.This article discusses the integrated design of the two,and analyzed the profit generated by the power plant using cold drainage from the LNG receiving station.
