Can the bottom steam reboilers of the stripping tower and the regeneration tower be replaced with other heating equipment?
Thread Content
Our facility has been using reboiler steam to heat the bottoms of the acidic water stripping tower and the solvent regeneration tower, which results in high energy costs. I would like to know if other companies have adopted any other better and more economical heating methods; your advice is greatly appreciated! ! !
Answer: Other heating devices can be used; electric heating devices or gas heating devices are both options. It should be noted, however, that the steam discharged from the bottoms of the stripping tower and the regeneration tower contains a certain amount of impurities; therefore, this may cause blockages in the combustion chamber during the reboiling process. Hence, special attention must be paid to removing these impurities from the steam coming out of the stripping tower and the regeneration tower.
The key is to meet the technical requirements of the reboiler: the temperature of the heating medium and the amount of heat supplied must be appropriate, and the material of the existing reboiler must meet the corrosion resistance requirements of the new medium.

Hello! Could you be more specific about the direct heating type? Thank you
Hello! Could you provide an example of a unit where this has been successfully applied, so we can consult in detail? Thank you!
There are now many heating methods that are more economical and feasible than steam heating with a Specific gravity boiler. For example, electric heating is usually more effective in saving energy consumption ； Additionally, you can also try waste heat recovery, which can also help achieve energy savings. Finally, you can consider using new types of heating systems, such as heat pump heating and solar heating, to replace the traditional steam heating from reboilers, thereby effectively reducing energy consumption costs.
As long as there is a heat source available, it can be used; for example, diesel from hydrogenation units.
Heat pump technology can be used to significantly reduce steam consumption
