This article used refined production of, synthesized gas one-step hydrogenation product, the ethanol dissociation system as research background. First, according to its physical features, it used UNIQUAC-RK property calculation method to simulate calculation of process flow of this system and then analyzed the remnant curve from Aspen plus software to determine its refined process flow. It adopted ethanol dissociation system refine tower model to simulate refined process flow on the ethanol dissociation system, set up refine experiment protocol, processed refine experiment according to this protocol, and obtained corresponding experiment result. Then it adopted ethanol dissociation system refine tower to simulate the experimental data and the simulation one is well fitted with experimental one so the model is verified as reliable one. Then it analyzed the agility of this system refine set operation parameters according to simulation optimization steps to determine relatively good operation parameters. The ethanol dissociation system refine set is designed and it used efficient loading and proper internal tower structure. This provided necessary experiment data and theoretical base for technique of ethanol by hydrogenation of methylacrolein.
