Improving on chemical process safety through distributed computer assisted knowledge analysis of preliminary design

摘要

Because accidents cause delays that have become increasingly expensive, the chemical industry should strive to improve safety by shifting from secondary protection to primary protection. The current design approach, that is basically reactive, is not fully adequate, as opportunities for technology are most efficiently realised in early design. A proactive framework, using the concept of 'anomalies', is proposed to identify desired as well as undesired relations of a system being designed. The proposed methodology also presents a strategy to deal with system anomalies. It efficiently prevents incidents that cause delays, helping to ensure profitability.
