Hazop procedure on an existing distillation tower of gas refinery

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 methodology for identifying hazards in continuous chemical plant design. This method is one of the best and the most rigorous techniques for identification of hazard and operability problems in a chemical plant. Hazop is a method of systematically identifying every conceivable process deviation, its abnormal causes and adverse hazardous consequences in a chemical plant. This paper presents a safety analysis for feed of an existing distillation tower as an important and effective part of the unit. Useful recommendations are presented to reduce ecological, personnel and asset risk ranking. It would also explain HAZOP procedures and helpful software for decreasing times and complexities of the studied system
