In respect of progress on the first utilization as ethanol brine and episode on the sales promotion of ethanol brine to the beer factories, lecturer reported on the story of experience. At a later period, application for the LNG liquefied gas of regenerator actualized as new adoption of ethanol brine system. Come to the conclusion it is necessary to prepare of ethanol brine data under the demonstration example, as the result, Japan Alcohol Association put together and published that research and development for 5 years as a trust business from Ministry of International trade and Industry.
