... to be considered that the change of pH with amine addition at elevated temperature is different from the one at room temperature. Therefore, it is required to predict the behavior of pH change when volatile amine is applied. The third one is to control water treatment at desired condition to the low-pressure...

...INTRODUCTION CO₂ corrosion in the oil and gas industry has been widely investigated. Nevertheless, research on CO₂ corrosion at elevated temperatures has rarely been conducted; consequently, the corrosion mechanisms remain unclear. One of the important factors...

... condition generated an aggressive acidic soil environment around the pipe. The coating and cathodic protection system in a low pH and elevated temperature (90-110°C) environment was not able to provide adequate protection from external corrosion for this flowline. coal seam soil acidification elevated...

...Abstract The 100mV cathodic polarization criterion is being used more extensively on piping in the oil and gas industry which has prompted a discussion on the limits of its use. This paper summarizes the technical literature on the validity of this criterion with respect to elevated temperature...
