Abstract

The graduation project was on the basis of the design assignment provided by the teacher. So I translated the foreign literature after discussing with my tutor in my college,  prepared a literature review, designed the technical process, and then,made the material balance. According to the determined process, material balance and heat estimate, all calculations and selection of the process equipment (including the selection of the reactor, distillation column , ancillary preheater, reboiler, condenser, cooler ,storage tank and pump) were completed. The material flow, the process flow chart with control points and the equipment layout were drawn. Depended on the selection of equipment materials and specifications, and the result of material balance, conducted the investment estimate and a simple economic analysis. Finally, the design technology calculation and the design specification were done.

Key words:2,4-dichlorotoluene;4-Chlorotoluene;material balance
