| Abstract: | By considering the high energy consumption in conventional n-butyl acetate production,a heat pump technique was proposed to be used in n-butyl acetate production,and a new flow sheet for n-butyl acetate production with heat pump distillation was developed.The principle and characteristics of the new heat pump technology were analyzed.The properties of the medium used and the optimal operation parameters for the heat pump process were studied thoroughly.The comparison of energy consumption and investment cost between the conventional process and the heat pump technology was presented.The results show that the new heat pump technology can decrease the energy consumption by 56.9%,which demonstrates that the proposed heat pump distillation is an energy-saving,cost-effective and green technology for n-butyl acetate production. |
