Gas Analysis

Process Gases

Amine Experts employs the same expertise resident in Sulphur Experts for its on-site analytical services. These specialised analyses include the following.

Bulk Gas Analysis

Employing specially developed in-house gas chromatograph systems, Amine Experts is able to determine the following compounds for amine plant applications:

Sulphur components: H2S, SO2, COS, CS2, mercaptans

Hydrocarbon components: CH4, C2H4, C2H6, C3H8, iC4H10, nC4H10, iC5H12, nC5H12, C6H6, C6

Air/inert gas components: H2, Ar/O2, N2, CO, CO2

The normal analytical range for H2 is 0.5 to 100 percent. The normal analytical range for the sulphur components is 1 ppm to 100 percent. The normal analytical range for all other components is 25 ppm to 100 percent. The analytical ranges for sulphur and hydrocarbon components can be extended to 0.1 ppm if required.

Special Analysis

Although not generally part of the routine (bulk) gas analysis, Amine Experts has the ability to perform special analysis on gas plant and refinery samples. Some of our special analytical capabilities include the sampling of:
  • NH3 (sour water stripper and amine acid gas)
  • HCN
  • Methanol
  • Mercaptans to C6 and other reduced sulphur species (di-sulphides, etc.)
  • Aromatics
