Gasoline vapor emissions in gas stations are regulated by the revised air pollution control law. Tatsuno Corporation and Mitsubishi Electric Corporation have developed a gasoline recovery technology and unit which intakes and liquefies the gasoline vapor leaked from the car fuel tanks while refueling. It has been confirmed that our targeted values: exhaust concentration below 2 vol% and gasoline vapor recovery rate exceeding 90 %, are achieved by compression, cooling and adsorption processes. The field test machine stably worked for one year with an average recover rate of 0.1 % or more. The sales of gasoline vapor recovery unit for the petrol dispensing pump are scheduled to begin in fiscal year 2009.
