AI Technical Summary
Existing dimethylamine production processes are energy-intensive and have high material consumption in distillation and separation systems. Ammonia water carbon dioxide absorption technology suffers from complex processes, high energy consumption, and severe equipment corrosion. Furthermore, research on carbon dioxide capture, conversion, and utilization lacks efficient methods under the global trend of low carbon emissions.
The carbon capture process, ammonia synthesis process, and absorption refrigeration process are integrated into one. The captured carbon dioxide and ammonia are used to synthesize dimethylamine. Dimethylamine serves as a heat source to provide high-temperature desorption and refrigeration, while the refrigerant is used for pre-cooling and cooling, thus optimizing heat utilization.
This technology simplifies the process, saves energy and reduces consumption, efficiently captures and converts carbon dioxide, and produces high-value-added products. It also improves carbon dioxide absorption efficiency and optimizes the heat utilization of the equipment.
