“…It can be defined as the ability of unsaturated surface atoms with a tendency of being compensated from environment. The dispersive interaction is mainly originated from van der Waals force, and polar interaction is mainly originated from the polarity of molecules [23,24]. Experimental measurements of surface energy (Table 1) of OAT modified by various contents of titanate and silane revealed that coupling agent had a drastic effect on the surface energy of fillers.…”

“…Some applications [86,87] use substances like carbon dioxide (CO 2 ) as the continuous phase, instead of water, to effect a dry-cleaning process for situations where materials being cleaned would be damaged by contact with water.

“…These properties, along with its good cleaning power and moderate cost, make PCE a very suitable solvent for dry cleaning, even though alternative and more benign chemicals, such as carbon dioxide (Banerjee et al, 2012) and propylene glycol (Hesari et al, 2014), have been recently evaluated.…”

“…PCE is a clear non-flammable liquid with a 121 °C boiling point; it shows good chemical stability, is non-miscible with water and has the lowest evaporation enthalpy among the chlorinated solvents. These properties, along with its good cleaning power and moderate cost, make PCE a very suitable solvent for dry cleaning, even though alternative and more benign chemicals, such as carbon dioxide (Banerjee et al, 2012) and propylene glycol (Hesari et al, 2014), have been recently evaluated.…”

Tetrachloroethene recovery and hazard reduction of spent powders from dry cleaning process

Dry cleaning facilities using perchloroethylene produce a solid waste consisting of spent filtering powders with a high content of residual perchloroethylene, together with dyes and non-volatile residues. Untreated spent powders, classified as hazardous waste, cannot be disposed in landfill and incineration represents the only viable alternative. In this study, together with a full characterisation of the waste, the removal and recovery of the residual perchloroethylene by means of different heat treatments was investigated. In particular, tests of distillation and stripping with air and steam were carried out, evaluating the effectiveness of the treatments by quantifying the residual perchloroethylene in the samples treated. The results obtained show that the spent filtering powders contained about 25% wt. of perchloroethylene and that the maximum perchloroethylene recovery was obtained by steam stripping; approximately 98% after only 50 minutes. However, this treatment accounted for the production of a liquid mixture containing perchloroethylene and of a solid waste that required a further washing with boiling water to decrease the residual organic content below the eligibility criteria for landfill disposal.
