Title The study of vapor recovery test procedure: Air to liquid volume ratio
Date of Defense 2006-01-04
Page Count 123
Keyword
  • air to liquid volume ratio
  • vapor recovery facilities
  • volatile organic compounds
  • Abstract Volatile organic compounds (VOCs) emitted from the vehicle refueling at gasoline stations include benzene, toluene, ethyl benzene, xylene, and MTBE, which are major air pollutants and hazardous. In order to reduce VOCs emissions from gasoline stations, the Taiwan EPA legislates and obligates the gasoline stations to establish vapor recovery facilities based on the U.S. control policy of the vapor recovery system with the gasoline stations.
    The objective of this study is to compare the differences between the Taiwan EPA’s test method“NIEA A211.70B”and the U.S. CARB’s Vapor Recovery Test Procedure “TP-201.5: Air to Liquid Volume Ratio (A/L ratio)”, which has the highest test frequency, the lowest qualified rate, and is most easily to cause disputes. This study also analyzes the accuracy and the precision of the equipments currently used in Taiwan and the testers’ exposures to the VOCs with different equipments.
    It is found that the installation of activated carbon in the portable liquid tanks could effectively reduce the testers’ exposures to the VOCs down to 1/23 of the current exposures. It is also shown that, although the equipments are quite accurate and precise, different testers will introduce different A/L ratios.
    The test procedures and management methods of Taiwan and U.S. CARB were also compared and discussed. It is found that U.S. CARB does not only revise the test procedure and management method constantly, but also devotes to develop facilities with higher gasoline vapor recovery efficiency.
