Abstract
It was observed that austenitic stainless steel plates of type 316, used in the extraction plant at the Jalu oil field, have weak corrosion resistance when exposed to hydrocarbon gases containing small amounts of hydrogen sulfide and carbon dioxide at temperatures ranging from 400 to 600 degrees Celsius. This study was dedicated to understanding the corrosion process using different ratios of hydrogen sulfide and carbon dioxide to create an oxidizing and sulfurizing environment at temperatures varying from 450 to 600 degrees Celsius. The flaky scales resulting from the corrosion processes were studied using microscopy and X-ray, and it was found that the corrosion rate was more effective in the sulfurizing environment.
