Analysis and Treatment of Micro Leakage of Heat Exchanger in Ammonia System
In this paper,the leakage of water cooler and ammonia cooler of ammonia compressor are studied,analyzed and judged,and the technological measures and suggestions for maintaining the operation of the system in a long period are put forward.Moreover,the measures of liquid ammonia subcooler and temporary negative pressure separation tank are used to extend the normal operation of the system of low temperature methanol washing system and ammonia system when the water cooler or ammonia cooler leaks slightly are extended.The results show that it is feasible to separate ammonia water and impurities from liquid ammonia subcooler by draining liquid and adding negative pressure separator,which can meet the safety operation of ammonia cooler when slight leakage occurs.
