Abstract

Petroleum warehouses and storage tanks are one of the major sources of air pollution. Therefore, this study aims to identify, assess and manage risks of air pollution in the central warehouse of Yazd Oil Products Distribution Company (OPDC). In this study, FTA Method was applied to identify environmental risks while E-FMEA was used to assess the risks. Based on the results of risk assessment, the highest RPN (equal to 336) is related to air pollution risk caused by respiratory and operational evaporation of the product due to lack of sealing of connectors. The second highest PRN equal to 280 is associated with operational evaporation of the product and the environment heat. In the pipeline, the highest RPN (tantamount to 180) is related to respiratory and operational evaporation of the product due to lack of sealing of connectors, while at loading platforms, operational evaporation of the product during its receiving and transmitting with RPN of 360 is identified as the most important air pollution risks. After identifying and assessing the environmental risks of air pollution, GIS Software was applied for zoning the air pollution. Accordingly, the risk map of air pollution on the site of oil storage was prepared. The results of the zoning suggested that the air pollution rate caused by NMTHC was occurred at Storage Section. Besides, the highest air pollution caused by SO2 was occurred at the southern side of the warehouse. Finally, risk management strategies as Kahab Project were proposed for Yazd Oil Products Distribution Company.
