Regulations require ultra-low sulfur diesel to contain under 15-ppm total sulfur content. Measuring this low sulfur level requires high-end laboratory equipment—often machines that generate high-energy x-rays. Fast, simple test methods enable spot-checking fuel quality to avoid asset damage, air pollution, and regulatory fines.

Amine residuals arrive at the refinery due to upstream chemical processing. These residuals are typically due to hydrogen sulfide scavenging with a triazine-based material. These amines will wash out at the desalter if properly treated. But proper treatment requires knowing amine levels. Measuring the amine content in the crude provides the information needed to handle new, opportunistic crudes without extensive, risky blending or in-process use.

Triazine-based sulfide scavengers are widely used in the gas sweetening process. However, they generate dithiazine by-products that can cause scale and fouling in processing and transportation equipment. This effect is especially problematic when water is involved during the preparation and transportation of NGLs, as dithiazine is water-insoluble. With a simple extraction into aqueous solution, dithiazine content can be measured simply and quickly, helping avoid system downtime.
