Dehydrator problem solving. Part 1. Analytical techniques can pinpoint glycol problems

Because various operating and engineering personnel may take widely differing approaches to combating problems encountered with glycol in natural gas dehydration systems, the specific analytical techniques that can accurately identify the problem and indicate the solution are discussed. Topics covered include water analysis, pH determination, gas chromatography, hydrocarbon analysis, and foaming characteristics. The judgement of the analyst and his communication with plant personnel will determine which of these analyses are most appropriate for a specific application.
