Abstract

The current study presents an effective method of determining and optimizing distillated methanol alternative arrangements. To complement the information required to run the rigorous simulation

min

method is used as a base for the selection of the optimum arrangement among different alternatives. Results obtained from

min

diagram and shortcut simulation are utilized

by means of the simulator

for the precise simulation of alternative arrangements of methanol distillation under optimum conditions. Taking into account target function profit and the process parameters and conditions

the most optimum parameter value for reaching maximum profit was obtained

based on which all the arrangements with or without their heat integration were compared to each other. Technical and economic analysis results indicate

that increased profit by Prefractionator with heat integration arrangement is 4.79% compared to the base arrangement

while the three-column

four-column and five-column arrangements have benefits increase by 3.61%

3.55% and 3.

46%

respectively.
