What are the ways to save energy in atmospheric and vacuum distillation units?
Steam condensate is recycled, improving the efficiency of vacuum equipment.
In general, the main energy consumption in atmospheric and vacuum distillation units comes from three sources: fuel gas, electricity, and steam. Among these, fuel gas accounts for approximately 80-85% of the total energy consumption. Therefore, to save energy, it is essential to focus on increasing the final temperature of heat exchange and maintaining a stable calorific value of the gas.
Everyone is focusing on fuel gas, steam, and electricity. The problem is that we have now reached its limits as well. In my opinion, we can focus on waste heat recovery, especially in those processes that require cooling with air or water at low temperatures, and explore ways to make use of that waste heat

Optimize the process parameters of the unit (properly control the outlet temperature of the atmospheric and vacuum distillation furnaces, as well as the temperature of each reflux stream). 2. Improve the heat transfer efficiency of the heat exchanger. 3. Allocate heat sources reasonably.
The key to energy savings in atmospheric and vacuum distillation lies in properly controlling the final heat exchange temperature at 313 degrees Celsius
If starting with combustion, I recommend oxygen-enriched or pure oxygen combustion! Efficiency will definitely increase by more than 10%! But after combustion with pure oxygen, the potential for CO2 recovery and utilization becomes even more intriguing! This technology is applicable to all combustion processes!
