Traditional internal lining schemes for the storage/transport of crude oil & refined fuels may no longer be appropriate. The aggressive nature of crude oil (high temp. & more sour), high purity refined products & increased use of biofuels demand better linings & more certain test results. The focus of this paper is to review the trends in test methodology from the early 1990’s to present.
Overview of coatings for a cyclic-temperature environment. Test method, including a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Factors to be considered for coating selection in the cyclic-temperature environment are discussed.c
This study describes a laboratory test system which was specifically developed to assess the ability of biocides to lower microbial corrosion rates. It was found that the common oilfield biocides THPS and glutaraldehyde, dosed at concentrations of 300 ppm for 4 hours weekly over 5 weeks, could reduce MIC rates from 109.7 mpy to as low as 4.3 mpy
