摘要
Abstract
Chemical synthesis pharmaceutical industry is one of the important emission sources of volatile organic compounds (VOCs) in China.Equipment leaks in manufacturing shop,tank area and sewage tank seal points were analyzed in a chemical synthesis pharmaceutical plant using the Leak Detection and Repair (LDAR) technique.LDAR was applied to a total of 462 equipment seals and 8 leaking points were detected,with a leak detection rate of 1.73 ％.Based on LDAR result,the emission of VOCs from equipment seals was estimated at 2.603 t/a using the correlation equation method.Among the various types of equipment seals,the largest contribution to VOCs leak emissions came from flanges,with a contribution of 89.4％,and the secondlargest came from pressure relief devices,with a contribution of 5.2％.It is suggested that LDAR technique be generally practiced in the pharmaceutical industry,and equipment seals with high leaking rates be repaired timely.关键词
