Abstract

The purpose of this paper is to explore the economy and efficiency of chemical separation process in order to provide theoretical support and practical guidance for the sustainable development of chemical industry. This chapter provides a systematic methodology for the economic evaluation of chemical separation process by constructing the economic analysis fr amework. The fourth chapter focuses on the efficiency analysis of the separation process, including the definition and measurement of efficiency, the analysis of factors affecting efficiency, the strategy of improving efficiency and the case study. Through in-depth analysis of key indicators such as energy efficiency, mass transfer efficiency and process integration efficiency, the paper discusses the effects of operating parameters, equipment design and material selection on efficiency, and puts forward corresponding efficiency improvement strategies. The fifth chapter discusses the comprehensive evaluation of economy and efficiency, constructs the comprehensive evaluation model, and analyzes the trade-off between economy and efficiency. Through case study and analysis, it shows how to achieve the optimal balance between economy and efficiency in the actual chemical separation process. Through the construction of comprehensive evaluation model and case study, this paper further verifies the effectiveness and practicability of the proposed method, and contributes valuable experience and insights to the sustainable development of the chemical industry.
