Device And Method For Separating Carbon Dioxide Generated In Clinker Production
Patent No. EP4416445 (titled "Device And Method For Separating Carbon Dioxide Generated In Clinker Production") was filed by Thyssenkrupp on Mar 30, 2023. The application was issued on Feb 19, 2025.
Patent Summary
A cement clinker production plant comprises a preheater, calciner, kiln, product cooler, and a carbon dioxide (CO2) separation device. To energy-efficiently separate CO2 cryogenically, the plant utilizes a cold preparation device configured as an absorption refrigeration machine. This machine features a solution circuit and a refrigerant branch, the latter containing an evaporator and a condenser. The refrigerant branch diverges from the solution circuit at an ejector (expander) and returns via an absorber. The system includes at least one first gas heat exchanger connected to the absorption refrigeration machine's expander. The plant may further employ an oxyfuel process, utilizing a heat collection device or turbines to recover waste heat from the product cooler to drive the absorption chiller.
