Remaining Life Analysis using Ø 2 Inch Piping System Dehidration Gylcol Process in Gas Production

Abstract

In the oil and gas industry, where there is a gas treatment process through a process of dehydration which is one of the
most important processes in the process of CO2 Removal. This is a problem in the LNG plant if the CO2 content is still above
5%. The presence of CO2 and water content of the product will cause corrosion of the coating on the pipe where the pipe is used
to distribute glycol of separator to the valve and frequent corrosion cause leaks. In this study, calculate the rate of corrosion and
remaining life of the glycol dehydration process piping. This calculation uses the standard ASME B31.3 and API 570. In the
analysis of the remaining life of 2-inch pipe B03 52 120 remaining life of the pipeline is lowest and the highest 3.83 years lifetime
of the pipe is 6.9 years. The conclusion of this study determines that the output pipe valve separator heading shows the highest
corrosion rate was 1.39 mm / year and the lowest was 0.81 mm / year. So which affect the rate of corrosion of pipes 2 inch diameter
carbon steel material API 5L Grade A is the water content, pressure and temperature.
