Title: GAS PRODUCTION SYSTEM
Abstract:
A gas production system that can supply liquefied gas obtained by rectifying source gas as product gas continuously with high heat efficiency without using a machine that has a risk of contamination like a pump.A gas production system (100) includes a single pressure device (30) having a single pressurised container (31) to which liquefied gas extracted from a rectification unit is supplied, a pressure line for extracting and vaporizing a part of the liquefied gas in the pressurised container (31) and returning the part of the liquefied gas to the pressurised container (31), and a second heat exchange unit (32) that is disposed in the pressure line, and a liquefied gas storage unit (41) that stores liquefied gas which is led out from the pressurised container (31).
