| titleOfInvention | Descaling of jacket of glass-lined vessels |
| abstract | In a method for descaling the inside of a jacket of a glass-lined vessel by using a cleaning solution containing a detergent and an inhibitor the amount of hydrogen permeated through the matrix of the instrument to the lining glass side is estimated by measuring a rate of hydrogen permeation through the jacket material or a test piece fitted to the circulation line of the cleaning solution and inserting the measured value into a previously established relationship between the thickness of a steel plate and a rate of hydrogen permeation, and the concentrations of the detergent and the inhibitor in the cleaning solution, the descaling temperature or the descaling time is controlled so that the rate of hydrogen permeation through the matrix may not exceed 30 ml per m<2> of the matrix during the descaling. A relatively large amount of scales can be rapidly and easily removed without causing breaking of the lining glass due to hydrogen permeation while minimizing corrosion of the matrix. |
