Abstract
Provided is a methanol plant that can obtain fresh water from sea water by using, in a seawater desalination device, the exhaust heat discharged in a step for producing methanol from natural gas. The methanol plant is provided with: a heat exchanger () that recovers into a thermal medium (for example, seawater) the exhaust heat discharged from a step for producing methanol from a feed stock (for example, natural gas); and a seawater desalinization device () that obtains freshwater from seawater using the exhaust heat recovered by means of the thermal medium.
