MEG Analysis: Fast, accurate analysis of water, oil, gas, and control fluids
OMMICA is a low-cost alternative to GC for ethylene glycol detection in multiple fluids and phases. It may also be used to manage MEG regeneration systems,

The OMMICA MEG analysis consists of a simple, highly accurate, portable colourimetric test to determine ethylene glycol in oil and water. It may be used in all types of crude oil, and in oil-based control fluids. It may also be used in water at all concentrations of MEG, for example to manage MEG regeneration processes.
Accuracy is gained by addition of accurately measured reagents to a sample. This is then reacted at a specific time and temperature, to control the reaction and the resultant colour gives the level of MEG.
Absorbance of the reacted sample colour is measured using a colourimeter to give an accuracy of +/- 1ppm.
The analysis has been developed to be as accurate as gas chromatography, but allow on-site testing to take place in the field or offshore, through use of portable equipment.
Pros & Limitations
1
Significant cost savings on traditional analysis methods
1
Designed to be easy for non-specialist users to use well
1
As accurate as Gas Chromatography
1
Designed to be used on- and off- shore
1
Water extraction of oil not required before analysis of oil samples
0
OMMICA is not an ASTM method, however it correlates well with the standard ASTM method using GC
0
Additional sample processing (dilution) required for MEG regeneration systems management (instructions provided)
0
The OMMICA method may require a couple of hours training for optimum results (can be provided)
