Environmental - Oil in Water Monitoring / Hydrocarbon Detection & Monitoring
Chelsea Technologies Group has a proven range of in situ sensors optimised for monitoring crude and refined oil. Applications include: reporting of hydrocarbons within Waste Water Treatment Plants, processing plants, natural water systems, pollution survillance, point source pollution tracking, hydrocarbon monitoring in ports & coastal area plus road & airport apron run-off monitoring. Systems are also available for detection of leaks in pipelines & subsea installations and for subsea control line leak detection.
The OIL-Station and OIL-Wader Systems enable in situ, real-time, reporting of Hydrocarbons within Waste Water Treatment Plants, water processing plants and natural water systems. The principle behind the measurement is the excitation of polycyclic aromatic hydrocarbon fluorescence within UV wavelength band, which has been shown to correlate with hydrocarbon contamination with high sensitivity. These systems can inform on hydrocarbon content at abstraction points and hydrocarbon contamination into processed waters tanks and entering into waste water treatment works.
OIL-Station & OIL Station Pro: Provides real-time, highly sensitive monitoring of dissolved Polycyclic Aromatic Hydrocarbon (PAH) in laboratory or process control environments. The OIL-Station comprises a CTG UviLux fluorometer and a Watchkeeper wall mounted data display and logger. Data is displayed on the Watchkeeper’s colour touchscreen and is logged internally. Up to three 4 - 20mA outputs are provided for data transmission.
OIL-Wader & OIL Wader Pro: Provides surveyors and regulators with real-time in situ measurement of dissolved Polycyclic Aromatic Hydrocarbon (PAH). The OIL-Wader comprises a CTG UviLux fluorometer and a Hawk handheld display and logging unit. CTG’s UviLux fluorometers detect UV fluorescence with industry-leading sensitivity and selectivity and have been optimised for minimal interference from water turbidity. Data is displayed on the Hawk’s colour touchscreen and logged internally.
|UV AquaTracka Fluorometer: Extremely sensitive UV fluorometers for the measurement in real-time of refined hydrocarbons (360nm) or crude hydrocarbons (440nm) in a wide range of oceanographic applications. In support of this, it has been designed to be deployed from gliders, undulating vehicles, moored or profiling systems.|
|Subsea Pipeline Leak Detection: This is the industry preferred tool for subsea pipeline leak detection. The system finds leaks by sensing the fluorescence of leaking hydrocarbons or, for pipeline commissioning, by introducing fluorescent dyes (such as Rhodamine, Fluorescein or Agma). This system provides both offshore pipeline commissioners and project engineers a highly sensitive detection system which allows quick location of leaks within subsea structures.|
