As an important separation technology, tray distillation equipment is widely used in chemical engineering, petroleum, environmental protection and other fields. In the operation of traditional tray distillation equipment, the mass transfer efficiency is affected by multiple factors, which limits its energy utilization efficiency and separation effect. Starting from the basic principles of the mass transfer process, this paper discusses the key factors for improving the mass transfer efficiency of tray distillation equipment, including the optimization of parameters such as gas-liquid contact area, operating pressure, temperature, and liquid flow rate. Combined with the application of modern new packings and trays, the hydrodynamic performance inside the tower is further improved. Additionally, the influence of multiphase flow on mass transfer efficiency is analyzed, and an optimization path based on numerical simulation and experimental research is proposed. Through these measures, the mass transfer efficiency of tray distillation equipment can be significantly improved, energy consumption can be reduced, and production economic benefits can be enhanced.
