Firstly, the plan was illustrated significance and function of Heptane and octane and status and development of research on Heptane and octane Secondly, the paper was introduced the design basis of problem, plant location and product specification. By all kind of methods of designing process comparison, the entire production process of material balance and heat balance is fixed. Through the design results, desulfurization tower and solvent regeneration tower and other major equipment choose the appropriate model, the major equipment was simulated by Aspen PLUS and based on an overall consideration of various factors, the paper was given a reasonable design of general layout of the shop, automatic control, safety and environmental protection, and utilities system. The 20000 words design brochures was completed, and the technological process chart, the workshop arrangement chart and the major equipment structure chart were drawed.
