Is there a cut-off temperature that defines vapour degreasing?
Vapour degreasing will not be defined by a temperature cut-off. Vapour degreasing is a process where condensing vapours facilitate the removal of soils from the surface of the object. This process requires that a vapour degreaser unit heat the solvent to its boiling point. Why do some companies use PERC? Tetrachloroethylene has a higher boiling point (121°C) than TCE (87°C) and is used when more aggressive cleaning is required in order to remove tenacious contaminants such as heavy or waxy hydrocarbons from metal. What are the years used to calculate the baseline consumption allowance? The proposed baseline allowance is calculated as the average of any three consecutive years falling into the period from 1994 to 2000, inclusive. The user is free to select any three consecutive years that produce the highest 3-year average. If the user does not have three consecutive years, they will be required to submit what years they do have and provide information as to when they began degreasing o
