Data obtained on the degree of protection at 80 C by the inhibitors NVS (oil-water-hydrogen sulfide) and Norust with a hydrogen sulfide content of 600-650 mg/liter are presented, and data obtained with an inhibitor concentration of 220 mg/liter and a variable hydrogen concentration are shown. The degree of protection and the corrosion rates on St3 low-carbon steel coupons were determined graviemetrically. The differences of the inhibitors in an autoclave and in a hydrocracking unit are presented. In the stream of drain water with a high content of hydrogen sulfide, the Norust did not give any protection even at a dosage of 37 g/ton; in fact, the inhibitor increased the corrosion rate. The NVS under the same conditions lowered the corrosion rate by a factor of nearly 2. The inhibitor NVS can be recommended for use under the conditions described in the hydrocracking unit in place of the currently used Norust inhibitor.
