Abstract
A method of treating hydrotest water to inhibits oxygen corrosion, microbiologically influenced corrosion (MIC) and to allow safe discharge of water. The combination treatment plan reduces biocide usage in a high pH brine. The reduced overall chemical usage facilitates meeting environmental guidelines while also minimizing chemical cost. The method includes: adding an oxygen scavenger to remove oxygen and prevent or minimize oxygen corrosion; raising the hydrotest water pH, typically in excess of pH 9.5; adding a biocide in reduced amount; and adding a scale inhibitor to inhibit scale.
