Risk analysis of a distillation column’s feed using Hazop procedures

Increasing technological complexity with social and legal pressures has made it necessary to improve safety systems. This need is particularly strong in the design and operation of chemical plants. Hazard and Operability study (Hazop) is a method of systematically identifying every conceivable process deviation, its abnormal causes and adverse hazardous consequences in a chemical plant.Distillation unit is one of the most important parts of a petroleum refinery. The qualities of a distillation unit’s products are directly affected by feed’s properties. Although a need for improving safety systems of studied refinery’s feed has been recognized, there were less systematical attempts for preventing dangerous accidents. This paper presents a safety analysis for feed using Hazop procedure. Useful recommendations are presented to reduce ecological, personel and asset risk ranking.
