Abstract
As a chemical graduates, we should be more systematically mastered the basic chemical engineering design procedures and methods, access to technical information to enable us to quickly carry out engineering calculations, using simple language, clear expression of their own design charts results of capacity increased. This is the purpose of this design.
The design, mainly for methanol synthesis and distillation section in the material and heat balance. The material balance, the theory is based on material balance equation. However, the specific calculations, the more side effects, side effects and some uncertain volume of production, so the reference in the calculation formula of some experience, make some approximations. The heat balance of the theory is based on heat balance, a little bit of substance in the calculation of the exact specific heat and heat of vaporization is difficult to find, so use the approximate value or experience points. Although this design made many similar terms, refers to the value of some experience, but are carried out in strict accordance with the relevant literature, so the design results to achieve the desired results.
Through this design has helped me to do the design calculations must be rigorous and realistic, while I feel that the knowledge learned in the comprehensive design of the chemical industry, the rapid development of the engineering calculation, and plenty of room to be improved.
Keywords: methanol synthesis; material balance; heat balance
