In the petrochemical industry, particularly in offshore petroleum production, it is necessary to analyze, measure, and monitor the amount of oil present during the extraction process. In order to accomplish this, specialized and precise instruments are used. This infrared technology then measures the oil in water content; the oil content in drilling mud and cuttings; the total petroleum hydrocarbons (TPH) in soil and water; and the fats, oils, and grease (FOG) in wastewater. |
Regardless of expertise level or experience, it is imperative to have efficient and effective analytical instrumentation that is not only safe for operators and the environment, but also adheres to federal regulations governing the industry. While such factors as life expectancy of equipment and measuring capacity are key in considering which oil in water analyzer to purchase, it is also important to consider the type of technology. This will depend exclusively on the nature and scope of the job the analyzer is intended for.
Consider Which Type of Solvent to Use
One way of determining which type of oil in water analyzer instrument to use is to make the determination based on the type of solvent used. The first option uses perchloroethylene, S-316, and Freon-113 as the extracting solvent. Instruments with this combination of solvents can range from a minimum detection water of 0.1 ppm to 2 ppm and a minimum detection limit soil range of 1 ppm to 10 ppm depending on the size and price point.
The second option uses hexane, pentane, cyclohexane, and Vertrel MCA as the extracting solvents. Instruments with this combination of solvents can range from a minimum detection water of 0.3 ppm to 8 ppm and a minimum detection limit soil range of 3 ppm to 40 ppm depending on the size and price point. However, additional features can make all the difference in the efficiency of your analytical instrumentation.
Other Features to Consider Before Making Your Purchase
Most oil in water analyzers come with standard features that most operators will likely notice. For example, a typical infrared instrument will include sub-ppm detection, multiple calibrations, internal data storage/export, touchscreen display, password protection, and an internal battery. However, more sophisticated models offer multi-language interface. Depending on who will be using the instrument and the location of the reading, operators may want to consider a model with multi-language interface.
