주유소 StageII의 유증기 회수설비 운영실태 조사를 통한 발전방안 연구

Gas station vapour is one of the most prominent sources of the volatile organic compounds in air of urban areas. This paper studied the current management statues of vapour recovery systems of stageⅡ at gas stations and suggested the improvement plans through analysis of case studies. Some 97.3%gas stations of target stations, which have to install the vapor recovery unit of stageⅡ, was completed by end of 2012. But approximately 18.5% of them did not pass the regular inspection caused improper operations and equipment obsolescence. There is a need for government"s technical support, regular training and management manual for gas station workers in order to be operating normaly of the vapor recovery unit of stageⅡ. Furthermore, it is necessary to expand the mandatory installation area for the vapor recovery unit of stageⅡ. For this, an expansion scenario analysis performed. The results showed that the expansion must be preferentially replied in 10 cities more than population of 500,000 when it was economic with a cost-benefit ratio was 1.43.
