Abstract

The article is devoted to the issue of reducing energy costs in industrial separation processes in rectification plants. The article reviews the ways to increase energy efficiency and reduce the costs of resources in industrial separation processes, assesses the possibility of using a heat pump as a secondary energy recycler in industrial separation processes. Calculation and comparative analysis of closed and open circuits for switching the heat pump into industrial separation facilities are presented. As a result of the analysis of the data obtained, it can be concluded that when using the “rectification column-heat pump of a closed type” installation, the heat energy consumption in the form of heating steam is reduced by 20% compared to the traditional installation, with the “rectification column-heat pump of open type” energy consumption is reduced by 35%. Also, the overall dimensions of the column itself are reduced, hence, the design becomes less metal-consuming, capital costs are reduced. The feasibility study of the option of switching the heat pump into industrial separation processes is given.

用于工业物质分离的节能系统“蒸馏装置-热泵”

本文致力于降低精馏厂工业分离过程中的能源成本问题。本文综述了在工业分离过程中提高能源效率和降低资源成本的方法，评估了在工业分离过程中使用热泵作为二次能源回收器的可能性。介绍了热泵转换为工业分离装置时的闭式回路和开式回路的计算和比较分析。通过对所得数据的分析，可以得出结论:采用“精馏塔-闭式热泵”装置时，与传统装置相比，加热蒸汽形式的热能消耗减少了20%，采用“精馏塔-开式热泵”的能耗减少了35%。此外，柱本身的整体尺寸减小，因此，设计变得更少的金属消耗，资本成本降低。对热泵转换为工业分离工艺的可行性进行了研究。
