Security Analysis of Caustic Tower Based on Six Sigma Theory

Six sigma management is a kind of advanced management technique to obtain the perfect quality and was used to analyze the security of caustic tower of ethylene unit under the joint action of two kinds of corrosion media.The main affecting factors such as H2S concentration,caustic concentration and temperature were analyzed,and the necessary condition was given for caustic wash equipment for safe operation under the joint action of two kinds of corrosion media.
