Notes
A procedure has been developed for analyzing chromium in the amine/glycol gas-treating solution from the Exell Helium Plant in Masterson, Texas. The amine/glycol solution is used to remove carbon dioxide and water from the plant's feed stream. Chemical analysis of the solution is difficult because of its water-soluble organic compound content, alkalinity, viscosity, and solids content. The procedure involves two-stage dilution of the sample with water, followed by graphite furnace atomic absorption analysis for chromium content. The effects of solution viscosity, particulates, acid digestion, and other impurities are documented.
