What is the criteria to decide whether service is Sour Service or Severe Sour Service?

Hi Yog123,

 

Please refer to NACE MR 0175/ISO 15156. There is a curve where you can define if you had entered sour service or not based on Partial pressure of H2S and pH. in ISO severe sour service is region 3. Mildy Sour is region 1. In between, you have the transition region
