Latest Patents

Lefebvre's latest patents include groundbreaking technologies such as "Post-combustion CO2 capture with heat recovery and integration." This invention improves COcapture processes by recovering thermal energy from specific streams for reuse in the stripping stage. The technology allows for thermal energy recovery from the overhead gas stream of a stripper operated under vacuum pressure conditions, as well as from flue gas. A heat transfer circuit can be implemented to recover thermal energy through indirect heat transfer, enhancing the efficiency of the process.

Another significant patent is "SOcapture using carbonate absorbent." This desulfurization gas process involves water vapor, CO, and SO2 and/or SO3. In this treatment unit, the gas interacts with a cooled alkaline aqueous solution, which cools the gas, condenses some water vapor, and absorbs sulfur dioxide in the carbonate-containing solution. The result is an SO-depleted gas and an acidic aqueous solution that can be further processed and reused.
