介绍了一种动静密封点泄漏的估算方法-泄漏检测与修复（LDAR）技术，开展了对制药企业的泄漏与修复工作。结论表明，检测点位共14 089个，可达点数为13 969个，不可达点数为120个。泄漏点位为40个，泄漏率为0.28%。经过对泄漏点位采取相应修复措施，成功修复了37个泄漏点，泄漏率降到了0.02%，泄漏损失率降低了92.8%；复检前40个点位泄漏量324.5 kg，复检后排放量94.6 kg，减排率为70.8%。年估算排放量为3 735.2 kg，年估算减排量为1270.7 kg。

A method for estimating leakage of static and dynamic sealing points-the leak detection and repairing technology (LDAR) is introduced,which is used to perform the leakage monitoring and repair works in pharmaceutical enterprises.The result shows there are 14 089 monitoring points,of which 13 969 points are reachable and 120 points are unreachable.40 leakage points are found,representing a leakage rate of 0.28%.After taking corresponding measures to repair the leakage points,37 leakage points have been successfully repaired,the leakage rate is reduced to 0.02%,and the leakage loss rate is reduced by 92.8%.Total leakage of 40 points is 324.5 kg before repairing,which decreases to 94.6 kg after repairing.The emission reduction rate is 70.8%.Annual estimated emission is 3 735.2 kg before repairing.The annual emission reduction is estimated to 1 270.7kg after repairing.
