Abstract: The process from petroleum to paraxylene is one of the most important chemical engineering technology in the field of petrochemical industry. Based on the design scheme of aromatic joint production of paraxylene proposed by our team, process system integration, plant location selection and factory layout were studied. Through the optimization of heat exchanger network , the process energy saved was proportional 30%. The plant site selection was located in Xuwei Chemical Industrial Park, Lianyungang in Jiangsu province. This area has significant advantages in the source of raw materials, transportation condition, preferential policies, infrastructure, social benefits, etc. The layouts of workshop, living zone and safety region presented shapes of “一”, “L” and “U” in the plant, which was in accordance with the concept layout rationalization, standardization and humanization. 

Keywords: paraexylene, process system integration, plant location selection, factory layout
