Environmental Risk Assessment of the Ethylene Process in Arya Sasol Petrochemical Complex and Providing Environmental Management Plan

This research has been done in the C2 cracker plant of Arya Sasol petrochemical Company for identifying Hazards and determination of maximum Risk Priority Number (RPN). Environmental Risk Analysis done by using of E-FMEA base on life cycle phase. After identification of production process, equipment and their function were studied. laboratory analyzed sample of pollutants material in air & wastewater and measured noise, were analysedPotentially damaging factors are identified and those were classified focused on the likelihood, extent of contamination, the possibility of recycling and the effect on the environment.Environmental aspects (= 64) and impacts (= 67) were identified by EFMEA method.20 risk (low), 30 risk (medium), 4 risk (high) and 10 risk were very high than degree of risk that higher risk was related to flaring operation and Greenhouse gas emissions of the furnace cracking with RPN=125. Regard with the degree of risk degree number (= 35), RPNs, this number is higher than the critical RPN introduced to control and define corrective actions.Among, Preventive and corrective actions mentioned installation exit pollutants of exhaust control system, air flow adjust, fuel injection to burner, recovery and re-use CO2, are sew to name.
