RISK EVALUATION OF BT EXTRACTION UNIT USING HAZOP PROCEDURE

A widely used hazard identification technique within the process industry is hazard and operability study (HAZOP). The technique was developed by ICI in the 1960s, and has been standardized for use in continuous manufacturing plants. HAZOP seeks to identify the hazard or operating consequences arising from the deviation. In petrochemical industries, benzene and toluene (BT) are separated from non-aromatics in a separation process that includes an extractive distillation column as a main part. This paper presents an introduction to HAZOP study and its related deviations then we evaluate the hazard of BT extraction unit for more realization. All of the deviations are considered and the recommendations are suggested to reduce the likelihood of consequences mostly related to the human factors
