The CO2OLHEAT project will be demonstrated in a real industrial environment and in the high technology readiness level (TRL 7) in CEMEX cement plant in Prachovice (Czech Republic).
CEMEX Plant in Prachovice has a wide untapped waste heat potential amounting to approximately 16 MW with hot spots close to the kiln/preheater, bypass, and the cooling towers, with the following characteristics:
|Temperature range||Flow rate|
|Cooling tower||100-400˚C||170.000-250.000 Nm3/h|
At the moment, this waste heat potential is not exploited in the facility, and it is rejected by means of dedicated water-cooling towers. These locations would facilitate the installation of the waste heat recovery unit (WHRU) and of CO2OLHEAT module, also enabling the possibility (via a dedicated by-pass) to cool down flue gases using the existing cooling towers. CEMEX is interested in replicating the CO2OLHEAT application in other plants of its group.
After its commissioning, the system will be tested for at least 9 months (2.500 operating hours of demonstration is targeted) and analysed at several industrial production conditions, loads and power ramps by CEMEX with the aim of characterizing the whole operational envelop and understanding the plant features.
