Petroleum Development of Oman (PDO) is currently operating and developing number of high pressure sour gas projects with high salinity (exceeding 200000 ppm of NaCl). This paper gives an insight into the challenges with these combinations of H2S pressure and Chloride and provides cases of field history explanation regarding material selection framework and technical challenges during the design execution and operating phases of some sour service projects. Some of the main challenges are: a) Unconventional high chloride levels carry over into process equipment downstream of the inlet separator b) Additional requirements for materials specification. c) Defining proper operating envelope for material performance. This paper addresses the challenges to provide ultimate engineering solutions through the use of corrosion resistance alloys and non metallic material to maintain the integrity of flowlines and process equipment in sour service.

Key words: Sour, H2S, corrosion resistant alloys (CRA), quality, application limits, quality improvement
