| Abstract: |
| Objective Determine the source of impurities in the solution and judge the foaming reasons of desulfurization solution. Methods Investigate the working fluid composition used in drilling, acidizing and anti-corrosion operations, and analyze the types of potential foaming substances. ResultThe lubricants in the drilling fluid, the drainage aids in the acidizing fluid and the corrosion inhibitors used during the gathering and transportation all contain surfactants, which have strong foaming ability. Conclusion Above foaming substances enter the desulfurization unit with high-speed flowing feed gas, which can lead to the foaming of desulfurization solution. |
| Key words: natural gas purification plant desulfurization solution foaming contaminant |
