Abstract

The invention relates to a gas-liquid double-effect passivation deodorant and a preparation method thereof. The gas-liquid double-effect passivation deodorant is applied to cleaning of petrochemical equipment and comprises fatty alcohol polyoxyethylene ether citric acid sodium salt, citric acid ferric salt, a corrosion inhibitor, a defoaming agent, a dispersing agent, a stabilizer, a pH value regulator and water. In the embodiment of the invention, the fatty alcohol-polyoxyethylene ether citric acid sodium salt has a good oil stain removal effect, and the ferric citrate has efficient ferrous sulfide passivation and deodorization functions. A gas-liquid mixed cleaning mode is adopted, the gas-liquid double-effect passivation deodorant is used for cleaning petrochemical equipment, ferrous sulfide passivation, deodorization and oil stain cleaning can be completed in one step, and the purposes of shortening the cleaning time, reducing the sewage discharge amount and saving the cleaning cost are achieved.
