CORROSION

CORROSION TESTING
Many plant and Field operators use coupon testing to get an understanding of the effect corrosion is having on their vessels and pipelines. APEX Technological has developed an alternative test to give you a broad view of the amount of corrosion in your system and some of it’s root causes.

THE ORGANICS
The test is done in several steps.  First a Millipore filter is samples through a meter to give a known weight per volume sample. This filter is then washed with hot hexane to determine percent oilwax and volatiles, and then with hot toluene to determine percent asphaltenes. This gives a total percent organics.

THE IN-ORGANICS
The remaining insoluble material represents the in-organics. This is analyzed through x-ray diffraction to determine which minerals are present. The presences of Iron Sulfides such asgreigite will indicate corrosion.  The sample is then analyzed through Energy Dispersive Spectrometry to determine major, minor and trace elements.

ON-SITE ANALYSIS
Analysis is done on-site to determine the amount of several corrosion causing agents. These are Hydrogen sulfide (H2S),oxygen, and water.

LAB ANALYSIS
A sample is taken and analyzed for C7+.  This will give the percent composition for another important species, CO2. A hydrate curve is also available for gas pipelines. 

THE RESULT
At APEX we believe this will give you a better overall view of the corrosion taking place in a system. With a series of tests preformed on a Pipeline over time you will be better equipped to make important decisions regarding corrosion in your facilities.
