Abstract:In cleaning system, the difference between free energy of supercritical fluid CO2 and solid phase is just the driving force to conduct the cleaning processes. The entropy, thermal capacity and enthalpy of every component under supercritical state are calculated by using Benedict Webb Rubin (BWR) equation. The cleaning powers of SCCO2 system in the different condition are calculated. The ideal ranges of pressures and temperatures of a SCCO2 cleaning system are discussed at which maximum cleaning efficiency can be received with minimum operational costs. The research results contribute to speed SCCO2 cleaning from laboratory or pilot-scale testing to industry implementation.
