Because of sulphide in crude oil of catalytic cracking unit increased, occurs decomposition reaction under the temperature
conditions of cracking reaction to build H2S and the concentration of H2S is too high and at the same time the nitride in crude oil arises splitting and create NH4 and HCN, but the temperature of absorb stabilization system is to lower and exist water, so
formed corruption environment of H2S—HCN—H2O style. Be aimed at this condition, we developed and produced Special
Corrosion Inhibitor for Catalysis LX-214A.This product is low base number multi-purpose built auxiliary, without heavy metal and other catalytic agent poisonous materials and the corruption rate less than 0.2mm/a(carbon steel).Major use for protect corrosion of condensation system of device top installation in the course of crude oil
distillation, and it is applicable for protect corrosion of fractionating tower top condensation system of other units.
