SAFETY CONSIDERATIONS IN-PROCESS SYNTHESIS

The aim of this work is to extend the computerized method for process pre-design to encompass safety aspects. Emphasis is on the choice betw een different process concepts. The synthesis method is integrated int o an existing computer aided process design tool. The method is based on six databanks which contain hazardous properties of chemical compou nds and knowledge of safe and unsafe process concepts. The first stage of the method is a rule-based synthesis where safety rules are combin ed with process rules. The second step includes a safety analysis of s ynthetized alternatives which is done by calculating safety indices ba sed on the safety properties of chemicals processed and the structure and conditions of the process.
