Report Title: Research on Zeolite Membrane Coupled with Heat Pump Distillation Technology for Organic Solvent Dehydration

Report Summary: To address industrial pain points in traditional distillation technology for organic solvent dehydration (e.g., alcohols, ketones), such as high energy consumption, azeotropic limitations, and difficulty in purifying low-concentration solutions, this study proposes a new energy-saving intensification strategy based on a zeolite membrane internally and externally coupled with a heat pump distillation unit. The report will focus on the deep coupling of membrane pervaporation and traditional separation processes by externally embedding membrane modules into the distillation column. This technology fully utilizes the thermal energy cycling advantage of the heat pump system, greatly improving the system's thermodynamic efficiency. Research results show that in the deep dehydration of alcohol systems (ethanol, isopropanol) and ketone systems (butanone, cyclohexanone), this coupled process can save more than 20% energy compared to traditional distillation while significantly reducing equipment footprint.

Report Title: Crossing the Temperature Difference Barrier: A Distillation Efficiency Improvement Solution Driven by Heat Pump and Vapor Compression

Report Summary: Against the backdrop of dual-carbon goals, the need for decarbonization in distillation processes is increasingly urgent. However, traditional thermal integration technologies are often limited by terminal temperature differences and material system characteristics. This report focuses on the collaborative innovation of heat pump technology and new water vapor compressors, proposing a "dual-drive" distillation thermal efficiency improvement solution. The report will analyze the core technical mechanisms of the dual-drive system in overcoming the barriers to conventional medium and high-pressure steam production. Using a steam application case from a pharmaceutical company, it will detail the technical difficulties of deeply integrating the thermal system with the chemical process. The discussion will focus on how to overcome the strict limitations of mixture boiling point elevation on the MVR compression ratio, as well as the safety redundancy and off-design operating logic of two-stage/cascade high-temperature heat pumps when crossing large temperature differences. Engineering practice proves that this system reduces steam costs by over 60% while ensuring high-purity output. The report aims to bridge the "last mile" from theoretical optimization to complex engineering implementation using hardcore practical data.
