Abstract: In a previous work, a software named DISMOL, was developed in order to simulate molecular distillation. However, due to the restricted access to this tool and the easiness to make use of data bank and physical properties, in the present work, it is proposed the development of general procedure for this highly specific process in the commercial simulator Aspen Plus®, Since no single unit operation is available in the commercial simulator that can appropriately simulate a falling film molecular distillator (MD), the proposal, in a preliminary approach makes use of a sequence of flash vessels in order to accomplish the task of MD simulation. Experimental data of a binary system distillated in a MD are used for the validation of the developed tool. The results indicate the high potential of this tool in representing a MD equipment, making possible the evaluation of different operational policies in conducting this high vacuum distillation to achieve products with the desired quality and properties. The development of the proposed computational tool is an important step for the investigations of operational policies for MD application in oil refining since no industrial data of such equipment is available. © 2009 Elsevier B.V.
