Although the reaction behind MEA-triazine production is simple, we have seen many examples of poorly-prepared solutions. Measurements like a total amine value, water content or density cannot determine the triazine content. But with Raman spectroscopy, it is possible to measure the triazine content directly.

One of the measurements about which I am frequently asked is the analysis of triazine-based hydrogen sulfide scavengers. Why? Triazine compounds are widely used, yet they are not easy to measure, either during production or during their application in the field. Hydrogen sulfide is a corrosive, hazardous gas. It can build-up in the headspace of a tank, creating a very hazardous situation for workers. It can affect “asset integrity”—in other words, cause corrosion and equipment failures. In the presence of sulfate-reducing bacteria, naturally occurring sulfate is reduced to H2S. And the world’s supplies of oil are on a continuous trend towards higher sulfur content.
