Study on the Deliming Using CO2 Supercritical Fluid as Reactant

Deliming using CO₂ Supercritical Fluid( CO₂ SCF) as reactant was investigated,and the effect of the presure, temperature and time on deliming and degrease was studied.The results showcd that CO₂ SCF can be used as a deliming agent.Deliming usiing CO₂ SCF as reactant had some advantages such as more quick, more completely than conventional methods,and can prevent thc formation of calcium spot.Furthermore, this new deliming method that avoided using ammornium salt had some degreasing ability.
