It is well known that amine chloride salts from use of monoethanolamine (MEA) triazine hydrogen sulfide scavenger can create major corrosion issues inside a crude unit. Recently new issues in a unit processing significant quantities of shale crude have been observed. There is evidence of significant physical fouling from polymerization of MEA triazine scavenger in the presence of hydrogen sulfide. This paper highlights this new impact.
