Oil Leak Detection.pdf

Power plants and paper mills use service water loops and mill water loops for cooling, while refineries use once-through cooling water systems. These systems can lead to oil leaks, which can be difficult to detect due to high water volumes. Traditional laboratory analysis methods can take hours to days to detect oil in water concentrations, resulting in significant oil loss.

Online monitors, such as fluorescence-based oil in water monitors, can quickly detect small intermittent leaks and indicate potential oil cooler tube failure. The TD-120 Oil in Water Monitor can detect petroleum-based fuels and lubricating oils at less than 1 ppm, with a fast response time and minimal maintenance.

Key features of the TD-120 include:
- Detection limit: less than 1 ppm
- Multiple measurements per second
- No sample preparation or reagents required
- Long-life LED and optical sensor(s)
- Expected operation: more than 5 years with minimal maintenance

The TD-120 can detect various types of oil, including:
- Mobil DTE 25: 0.12 ppm limit of quantification, 5000 ppm linear range
- Mobil DTE 797: 0.18 ppm limit of quantification, 5500 ppm linear range
- Terresso: 0.09 ppm limit of quantification, 4500 ppm linear range
