Research On Energy Saving And Consumption Reduction Of Ethyl Acetate Production Process And Process Simulation

Reactive distillation is reaction and distillation process together, and in the same equipment within the coupling process. Aspen Plus is production plant design, simulation and optimization of large general process simulation system, the world’s largest industrial manufacturing enterprises and famous engineering company are Aspen Plus user. Ethyl acetate(ethyl acetate) is an important downstream products of acetic acid, excellent ability to dissolve and the performance of the quick drying, solvent can be used as a variety of chemical products, its potential commercial market outlook is generally positive.From the existing ethyl acetate production process, widespread esterification part of the problem of high proportion of the steam consumption. People for energy-saving reconstruction of ethyl acetate production process has done some research, successively developed a salting out, pressure distillation, extraction, washing and improvement methods such as butyl acetate and water. Own company ethyl acetate production device, the esterification of steam consumption is also high proportion, it has become a major problem restricting the development of devices and even the company. How to process improvement, reduce energy consumption of unit become an urgent task, it will be of great benefit to improve the competitiveness of the company’s products in the market, at the same time also accord with the green environmental protection, energy saving and consumption reducing beautiful governing philosophy in China. Based on the company’s existing ethyl acetate production process, the three methods of decreasing the consumption of primary research and comparison, and through the Aspen Plus simulation software, choose the most effective and feasible one scheme that companies adopt.
