This paper is to investigate how alcohols are expressed when they are dried from simulating each important apparatus of a system, to determine the direction of the system framework and to predicate what the condition of the reaction mechanism will be for further improvement to see whether the efficiency can be hiked and the amount of catalyst usage saved, thus reducing energy losses. Inside the single-operation tower is the mixture of ethanol and water, which is mainly to determine the flow and the flowing condition with computational fluid dynamics (CFD). By first drawing an ideal number of panels using the ethanol gas-liquid equilibrium diagram, and then calculating and verifying the theoretically accurate number of panels using EXCEL, we can assess whether or not the flowing condition of the single-operation tower meets expectation. We will draw the profile of the distillation tower system by using the built-in graphic software GEOMETRY in ANSYS and observe the distillation tower condition after setting parameters from FLUENT, and then draw the reactor system and predicate the results with conditional parameters being set. Then, we will discuss analytical results.
