NOVELTY - A bio-methanol production system consists of a gas compressor (1) which compresses a gasifying gas, a gas-purification installation (2) which purifies the compressed gasifying gas, a methanol synthesis reactor (3) which produces methanol-containing gas, a cooler (4) which cools the methanol-containing gas, an impurity removal installation (5) in which moisture content in the methanol-containing gas is removed, a methanol solution (LM) and a gas cooling separation facility (6) where the methanol-containing gas is cooled and separated into an off gas.    USE - Bio-methanol production system is used for production of bio-methanol (claimed) used as fuel.    ADVANTAGE - The bio-methanol production system enables production of bio-methanol having excellent purity by simple and economical process.    DETAILED DESCRIPTION - A bio-methanol production system consists of a gas compressor which compresses a gasifying gas obtained by gasifying biomass feedstock using a gasification facility, a gas-purification installation which purifies the compressed gasifying gas, a methanol synthesis reactor which synthesizes methanol from the purified gas and produces methanol-containing gas, a cooler which cools the methanol-containing gas to predetermined temperature, an impurity removal installation in which cooled methanol-containing gas is contacted with moisture-content adsorption agent (51) and moisture content in the methanol-containing gas is adsorbed to the moisture-content adsorption agent and removed, a methanol solution, and a gas cooling separation facility where the methanol-containing gas is cooled and separated into an off gas. An INDEPENDENT CLAIM is included for production of bio-methanol, which involves gas-compression process, gas-purification process, methanol synthesis process, cooling process, impurity removing process and gas cooling separation process.
