Abstract
The paperintends to introduce an improved safety technology management system for ethylene oxide device processing developed by the author. As is known, high-temperature runaway accidents,which are likely to lead to shutdown of petrochemical devices and even more serious accidents. Such is often the case in the production process of the fixed bed reactor with the ethylene oxide device. To solve the problem, we have done experiments and adopted the hazard and operability analysis(HAZOP)for analyzing the whole production process of the devices, and thenworked out a safety management system for their safety production. In preparing our system, we have discussed and analyzed the following problems:(1) corresponding conditions of deviation, cause and effect, etc.;(2)the expression mode of the hazard-occurring likeliness.Through the HAZOP analysis of the epoxidation reaction process, we have established the epoxidation reaction model of the fixed bed reactor, as a result, conforming thatitis possible forus to use the experimental results to verify and explain the HAZOP reaction consequences. Combining the process safety technology resources of the production device with the HAZOP analysis results, we have time again examined the safety management system of the process technology for ethylene oxide device, inwhich the key link is to ascertain the influential relationships between the dangerous paths identified by HAZOP analysis and the processing of the safety technology resource files,which should properly be matched with the HAZOP analysis results. In case any abnormality occurs, the operator should be able to quickly find out the locations of the necessary files and keep them in the program database so as to find the errors for the abnormal situation and make it right. Successful application of our safety management system can help greatly to increase the safety of device operation, human safety and operational ability of the petrochemical industry in a variety of ways.
