Research on Corrosion Factors and Corrosion Prevention Measure of Carbon Steel in Produce Water of Reverse Osmosis in Power Plant

With the wide use of reverse osmosis technology in power plants, many produce water distribution networks of first-order reverse osmosis of seawater have severe corrosion, which is a threat for the normal and efficient operation of power plant. This paper studied the effect of corrosion factors such as dissolved oxygen, chloride ion, flow velocity, temperature on first-order reverse osmosis corrosion by carrying out coupon tests, explored the measure of adding corrosion inhibitors to produce water in order to reduce product water corrosion on the based of the above research results, and then proposed a useful anticorrosive method which suits for power plant. The research result of this paper can provide operation guidance to power plant and has obvious social benefits and practical application value.
