E. Norwalk, CT - The Petroleum Industry – both offshore and onshore – has regulations that limit the amount of oil in discharged water. Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal Analyzers are compact (typically 6 inches or 15 cm square, weighing less than 5 or 6 lbs) and rugged enough to withstand salt air and a rustic lab set up. The operation can be done by non-technical personnel in less than 15 minutes. Infrared methods also match well with onshore laboratory testing, making it a reliable way to keep effluent levels under the regulated amount.
Both the InfraCal Model HATR-T2 and new InfraCal 2 ATR-SP, use hexane, pentane or Vertrel MCA for the extraction process. Measurement data from either model will correlate to EPA Method 1664 as both procedures are based on evaporation techniques and measuring the residual oil and grease. They are equipped with a built-in cubic zirconia horizontal attenuated total reflection (HATR) stainless-steel sample stage on which the extract is deposited for analysis. The sample preparation takes a few simple steps and the ppm hydrocarbon result is obtained in less than 15 minutes. The InfraCal Model HATR-T2 has a minimum detectable limit of 8 ppm oil in water and the InfraCal 2 ATR-SP will measure down to 0.3 ppm.
The InfraCal Model CVH and new InfraCal 2 Model TRANS-SP are based on US EPA Methods 413.2 and 418.1 and ASTM D7066-04, which uses Freon 113, perchloroethylene, or S-316, as the extracting solvent. Since the oil concentration is measured directly in the solvent, light end volatile components are retained, making it ideal for gas condensate measurements. The sample preparation takes a few simple steps and the result is obtained in less than 10 minutes. The InfraCal Model CVH has a minimum detectable limit of 2 ppm oil in water. It was one of the instruments used to develop the ASTM D7066 oil in water method. The InfraCal 2 TRANS-SP will measure down to 0.1 ppm.
