Zusammenfassung:	1376886 Inhibition of scaling TEXACO DEVELOPMENT CORP 20 March 1973 [4 May 1972] 13219/73 Heading C7E Scaling of bodies in contact with scale-prone water is inhibited by adding to the water a sulphonated alkali lignin. These are made by treatment of lignin with alkali followed by sulphonation; the amount added is preferably 0À0005- 0-01 wt per cent, and scaling may be inhibited in oil-well equipment by adding either a 1-50 wt per cent concentrate or solid compound to water in contact with the equipment.
