STRUGGLE WITH CORROSION IN PETROLEUM REFINING INDUSTRY OF CZECHOSLOVAKIAN SOCIALIST REPUBLIC
Abstract
Investigations conducted in ChSSR and USSR showed that the most essential condition of lowering corrosion is deep desalting of oil. In heavy conditions of desalting (Romashkinskiy oil), nonionic de-emulsifiers turned out to the most profitable. During processing of sulfurous oils one should select materials, resistant to corrosion by sulfurous compound. In the process of work on old equipment from carbon steel, corrosion is lowered by means of introduction of so-called film-like inhibitors of corrosion into steam outgoing from distillation installations. Meanwhile there are only preliminary results indicating lowering of corrosion of loaded components and component parts during the use of inhibitors. World and domestic experience of the struggle with corrosiveness of petroleum products shows that the most promising is by means of application of suitable additives. Experiments in this area are conducted in ChSSR chiefly on a laboratory scale. From first experiments the most interesting are with colloidal additions against vanadium corrosion, and with complex additions of the anthranilic acid type.
