| titleOfInvention | Method of removing scale in jacket of apparatus made of glass lining |
| abstract | PURPOSE:To easily remove the scale formed in a jacket without damaging the same by using a hydrochloric acid soln. contg. compds. such as lauryl amine and lauryl dimethyl amine and stannous chloride. CONSTITUTION:The hydrochloric acid soln. contg. at least one kind of the compds. selected from the lauryl amine, lauryl dimethyl amine and propargyl alcohol and the stannous chloride is prepd. The hydrochloric acid soln. which is the prepd. cleaning liquid is then circulated in the jacket to dissolve away the scale which consists essentially of iron oxides and is formed in the jacket. The concn. of the above-mentioned amines, etc., to be added is specified to about 50-1,000ppm to the aq. hydrochloric acid soln. The concn. of the stannous chloride to be added is specified to about 0.1-5% to the aq. hydrochloric acid soln. The concn. of the hydrochloric acid is specified to about 5-15% and is used in an about 40-70 deg.C range. The corrosion of the base material is minimized in this way and a large amt. of the scale is rapidly removed. |
