Information

Taking into account the growth of suitable microorganisms in the circulating cooling system of the oxygen plant, the scale sample was first immersed in 0.3% hydrogen peroxide at a temperature of about 35 ℃ for 1 h for pretreatment, and then immersed in 1%, 3%, 5%, and 7 %, 8% sulfamic acid solution, add 0.3% sulfamic acid special corrosion inhibitor, soak at a constant temperature of 45 ℃. Knot
The results are shown in Table 2.
From the comprehensive comparison of the results of Table 1 and Table 2, it is determined that the process parameters used in the dynamic simulation test are: 0.3% hydrogen peroxide, pretreated at a temperature of about 35 ℃ for 1 h; sulfamic acid concentration mass ratio 3% to 5%; sulfamic acid Acid special corrosion inhibitor 0.3%; temperature 40~50 ℃; time 4~6 h.
3.2.2 Dynamic simulation test
According to the process parameters, the dynamic simulation test was carried out on the simulation test platform, and then neutralized with 0.2% trisodium phosphate at 35 ℃ for 1 h. The results of the dynamic simulation test confirmed that the process parameters determined by the static test are correct and feasible. The sulfamic acid cleaning is selected as the cleaning agent, and a static small-scale test is first carried out. The items include sulfamic acid concentration, temperature, time, corrosion inhibitors and additives. Then, on the basis of the static small-scale test, a dynamic simulation test is performed to simulate the process of pickling, washing, neutralization, passivation and so on.
