Corrosion and Protection of MVR Facilities for Wastewater Treatment in Chemical Industry
Petroleum and petrochemical and other chemical production produce a large amount of industrial wastewater.The industrial wastewater contains high concentation of salt substance,which cause the treatment to be difficult and costly.The wastewater concentration and crystallization can be realized by heating evaporation and recompression technology.High concentration of salt substance in wastewater,chloride and other aggressive impurity as well as high temperature during treatment process might cause corrosion risks.In this article,the corrosion factors of high chlorine and high salt concentrated industrial wastewater are analyzed.Based on the typical corrosion situation,the new type of wear-resistant anticorrosive coating is the most effective way to control the corrosion of facilities such as MVR evaporator.
