醋酸酯加氢制乙醇的精馏工艺及能量耦合 Title: Distillation Process and Energy Coupling in the Hydrogenation of Acetate to Ethanol Abstract: This paper explores the distillation process and energy coupling in the hydrogenation of acetate to ethanol. The conversion of acetate to ethanol, avaluable fuel and chemical, has gained significant interest due to its potential as arenewable energy source. The use of distillation technology and energy coupling plays acrucial role in the production of high-purity ethanol. This paper discusses the process steps involved in the distillation of raw materials, separation, and purification of products, as well as the energy integration techniques used to optimize the overall efficiency of the process. Additionally, the challenges and potential solutions for improving the energy efficiency and sustainability of the process are examined. 1. Introduction The hydrogenation of acetate to ethanol is apromising method for the production of ethanol, which is widely used as afuel and chemical precursor. Distillation is akey separation technique employed in the purification of ethanol. Energy coupling, on the other hand, involves the integration of energy streams to enhance overall process efficiency. This paper aims to provide an overview of the distillation process and energy coupling techniques used in the synthesis of ethanol from acetate. 2.
