What about the energy balance? If your capture is exothermic you will warm up the cooling water and your client will not have enough cooling for their process.

What about the energy balance? If your capture is exothermic you will warm up the cooling water and your client will not have enough cooling for their process. When you regenerate, do you need to add energy? How much CO2 is generated by the energy you need?. If you have to add heat to regenerate, how do you now cool the water back down to the temperature required by your client? Most industrial cooling systems use carbon steel pipes, shells and tubesand, although many heat exchangers will be stainless steel especially if they are plate type. Chemicals are added to prevent scale and to inhibit corrosion. You CO2 capture chemical needs to be comparable.
- jsantos511 6y agoThe energy balance is going to be critical, I agree! We are still working on finalizing all the inputs for this process, including regeneration amounts, amount of heat added, etc. Based on our early modeling, it seems the amount of heat generated from the capture will be negligible since the amount of CO2 moving through our system is much smaller than the amount of water available to provide cooling. Our chemicals have anti-scaling properties, and we're working to understand corrosion across many different material types to ensure we don't cause more problems than we're solving.
