Liquefied gas regasification apparatus and regasification gas production method

摘要

A liquefied gas regasification plant which can regasify liquefied gas by a shell-and-tube-type heat exchanger with a simple configuration by preheating the liquefied gas with a simple configuration is provided. The liquefied gas regasification plant includes a preheating heat exchanger (3) that preheats LNG flowing through a preheated flow (3a) by gasification gas flowing through a preheating flow (3b), and a first shell-and-tube-type heat exchanger (5) that regasifies the LNG preheated in the preheating heat exchanger (3) by seawater or fresh water, the gas regasified in the first shell-and-tube-type heat exchanger (5) being guided to the preheating flow (3b), the liquefied gas regasification plant further including a second shell-and-tube-type heat exchanger (7) that regasifies the LNG condensed through the preheating flow (3b) by seawater or fresh water.
