| Abstract: | The effective measures such as nitrogen purging, etc, were proposed based upon the hydrogen sulfide corrosion conditions of the tail gas pipeline of sweetening unit. Among these measures, selection of 0Cr17Ni7Mo2 stainless steel was the most cost-effective way to reduce the corrosion. The annual corrosion rate was only 0.07 mm. |
