✦ Synopsis

Comparative tests of a number of chemical additives-scale formation inhibitors, of phosphonate (IIAGI3A 1, polyelectrolyte ~J_:.:Yij:CXX!~) type and others, being applied in the USSR and abroad, were carried out. The investigations were conducted on a laboratory installation. The processes of scale formation in the form of magnesium hydroxide, calcium carbonate and sulphate were simulated in them. In order to eliminate mutual superposition of scale formation processes of different types that is inevitable at sea water use, simulated solutions were applied, It permitted to evaluate the effect of chemical additives on the formation process of each scale type. From the chemical additives tested there were determined the most efficient inhibitors of scale formation of magnesium hydroxide, calcium silphate and carbonate. It was shown that most of the chemical additives didn't inhibit magnesium hydroxide scale formation.
