Abstract: The petrochemical industry normally uses Liquefied Petroleum Gas (LPG) tanks which contain considerable volumes of flammable chemicals. Thus, the occurrence of a LPG tank accident is possible and usually leads to fire and explosions. During the fire, large amounts of CO2 , CH4 , CO and black carbon aerosols 2 4 were injected into the atmosphere. Release of toxic chemicals by explosion or combustion of industrial facilities can similarly lead to large environmental problems (such as air pollution, increase of green house gas) and public health disasters. In last 50 years, trade organizations and engineering societies such as American Petroleum Institute (API), American Institute of Chemical Engineers (AIChE), American Society of Mechanical Engineers (ASME) and National Fire Protection Association (NFPA) have published strict engineering guidelines and standards for the construction, material selection, design and safe management of storage tanks and their accessories. Most companies follow those standards and guidelines in the design, construction and operation but tank accidents still occur. In this study, all requirements related to the four stages of design, construction pre-commissioning and operation of LPG tanks With a view to reducing the environmental impacts were extracted. Then by Analytical Hierarchical Process (AHP) the requirements were ranked and it became clear that the design phase is the most important role in reducing the environmental impact.
