SAFETY ANALYSIS OF A PLANT FOR THE PRODUCTION OF VINYL ACETATE

抄録

A fault tree is constructed to represent the major failure mechanisms of a plant for the production of vinyl acetate. Component failure rates from different sources are compared and provide input information for its quantitative evaluation. Results with and without inclusion of human error are calculated and proposals for an improvement of the original design are made. The dispersion of failure rate data is described by a log-normal distribution and its effect on the value obtained for system unreliability is assessed.
