Online Oil in Water Monitoring

The Oil in Water Monitors are primarily used for legislation purposes. This to prevent any penalties or discussions on environmental issues.
Oil in water monitors are also used to get more information on the behaviour of water emissions.

With ppm and ppb oil in water ranges, most online oil in water measurements have difficulties with background interferences and scaling problems. Especially with produced water applications, there tend to be a lot of interfering components effecting most of the oil in water monitors available on the market.

Working principle:

The oil in water monitor of Turner Designs Hydrocarbon Instruments uses an unique non-fouling optical instrument. This oil in water monitor can easily detect and measure the low concentrations in water. The method used is displayed in the figure below.

The oil in water monitor detects the aromatic hydrocarbons in a stream of water which falls through an open chamber. With this oil in water monitor, the stream does explicitly not contact, dirty or foul the optical windows used, by using a proprietary air curtain system. This oil in water monitor measures the fluorescence of the hydrocarbon components in the water. Fluorescence takes place if a molecule absorbs the light energy at a specific wavelength and sends it out with a larger wavelength.

Depending upon the application, the online oil in water monitors come in different designs and constructions:

TD-4100 Oil in water Monitor:

This on-line oil in water monitor is capable of a reliable determining the amount of BTEX, fuel, diesel, kerosene and crude oil in water. This extremely accurate online oil in water monitor can determine the amount of hydrocarbons in water with an ppb accuracy. Most common applications are effluents ranging from industrial water to water from the ground.

Certified: General Purpose

TD-4100XD Oil in water Monitor:

This ruggedized version of the TD-4100 online oil in water monitor is specifically designed for offshore oil production, refining, petrochemical, mining and other industries that require a more robust design for severe duty and hazardous locations. The used materials including the keypad are all 316ss suitable for corrosive environments and will be mounted on a skid.

Certified: Explosion proof Zone 1 and 2

TD-500 Portable oil in water monitor:

This extremely low costing, portable, user friendly and accurate oil in water monitor can determine the amount of oil and condensate in produced water, desalter tail water, tank bottoms, cargo heaters or anywhere that crude oil comes in contact with water.

TD-3100 Lab instrument:

The TD-3100 is a benchtop oil in water monitor which can measure samples with BTEX, fuel, diesel, kerosene and crude oil in water directly (non-extraction) or with solvent (i.e. hexane) extraction methods.

TD-1000C Oil in water Monitor:

This low costing TD-1000C continuous on-line oil in water instrument is most commonly used to detect fuel oil, crude oil, turbine lube oil, diesel, and other fuels and oils at low parts per billion (ppb) in steam condensate and cooling water. The signature fluorescence detection system provides the highest sensitivity with minimal interference from suspended solids. It comes to you complete and ready to be installed in your system with a pressurized side stream from the process. It includes 316SS mounting bracket and isolation valves.
