Emergency shutdown of fluidized bed reaction systems

In chemical plants, the pressure to prioritize production and minimize operating costs often leads to delays in safety investments. To allocate limited management resources effectively, decision‐making regarding safety investments must follow a logical approach. This article outlines how engineers can provide valuable information to the management, enabling them to make informed decisions. We demonstrate that decision‐making involves both technical and economic considerations, following a well‐defined process with distinct stages. This study highlights the importance of technical data in making informed decisions regarding safety investments. Decision makers must consider various factors, including risk assessment, economic efficiency, technology reliability, and construction safety. In addition, economic efficiency considerations should incorporate new proposals that account for environmental profit/loss. Our findings confirm that effectiveness of the proposed method, particularly when applied to fluidized‐bed reactors. In conclusion, accurate allocation of management resources at appropriate times leads to reasonable risk reduction.

A very reliable control system for offering a safety layer in emergency scenarios is an emergency shutdown system, or ESD system. It aids in preventing crises from having disastrous effects on the economy, the environment or business operations. In any plant, emergency shutdown systems reduce the risk of harm to the working population, the environment or equipment damage by guarding against leaks, hydrocarbon escapes, fire outbreaks and explosions. The ESD system halts process activity in an emergency, ensures that the hazard is isolated and does not worsen. It is essential that there is a clearly defined emergency procedure in place when a facility needs to be shut down in an emergency. When preparing an emergency procedure for use in an emergency, it is crucial to prioritise the operations. The factory uses an Interval-valued Intuitionistic Fuzzy Analytical Hierarchy Process (IVIFAHP) to prioritise activities in emergency situations. It is possible to design emergency shutdown systems using the aforementioned order of operations. It is possible to properly set up safety measures using the multi-criteria decision-making approach (MCDM). The Analytical Hierarchy Process (AHP) compares variables without taking measurement scales or units into consideration, which is a distinct benefit. The AHP’s handling of ambiguity, uncertainty and imprecise data is improved by the IVIFAHP.
