化工装置中的某些设备、由于设计、制造施工上的欠妥及管理上的不善,而造成物料的泄漏和损失。由文献报道的数据(表1),不难看出,一些微小的泄漏,天长日久其泄漏量是相当可观的。随着世界能源的危机、节能和文明生产的要求,这些微小泄漏已引起人们的重视。 Some equipment in chemical plant, due to the design, manufacture and construction of defective and poor management, resulting in material leakage and loss. Data reported by the literature (Table 1), it is easy to see that some minor leaks, over time its leakage is considerable. With the world’s energy crisis, energy saving and civilized production requirements, these tiny leaks have attracted people’s attention.
