MS1700 - Oil in Water Analyzer

The MS1700 is an on-line oil in water analyzer designed to detect and measure hydrocarbon concentrations in water up to 100 mg/l in industrial processes, refineries and petrochemical complexes.

Using a state of the art contactless technology the MS1700 provides a solution that is not affected by turbidity and can detect all the volatile hydrocarbons independently from their fluorescence properties.

Applications

  • Oil detection in Cooling Water
  • Oil detection in produced water
  • Detection of phenols in discharge water
  • Effluent monitoring
  • Pre-filtration monitoring
  • Oil in wastewater
  • Filter protection

Features and benefits

  • No sensor contact with water: low maintenance, no sensor cleaning
  • Measures both Polycyclic Aromatic Hydrocarbons (PAHs) and VOCs
  • Electronic Nose: not affected by turbidity
  • Can be calibrated for specific substances: used to monitor known spills
  • Catches fluorescent and non-fluorescent compounds
  • Alarms to SCADA and other communication interfaces

The MS1700 oil in water analyzer is designed to detect concentrations of up to 100 mg/l and it’s used in a variety of applications such as:

Oil in cooling water

Hydrocarbons are an ever present class of compounds in industrial processes, factories and industrial plants of all sorts. A leaking piece of equipment, a corroded heat exchanger, a leaking diesel pump or simply an accidental spill can mean that cooling water gets contaminated with hydrocarbons. When this happens an oil in water analyzer, like the MS1700, can help to detect contamination in the cooling water early on before it creates major issues.

Phenols

Phenols are widely used in industry as one of the starting material to produce plastics, explosives and drugs, however, they can be harmful for the environment and companies that deal with phenols need to comply with very strict emission limits.

Influent water

Wherever water and hydrocarbons get mixed together in a process (refineries, petrochemical processes etc) there is a need to treat this water before it’s used further down in the process or discharged into the environment. This influent water has usually got high levels of hydrocarbon and, depending on the incoming level, the treatment can be optimised.

MS1700 - Oil in Water Analyzer Datasheet PDF
What does the MS1700 measure?
It measures the concentration VOC in water measured against a target gas standard (usually toluene). Other compounds can be targeted.
How often does the instrument provide a reading?
The instrument provides a reading via the 4-20 mA output continuously.
What is the reported value?
The reported value is Total VOCs in the effluent water, in ppm, is in the range from 1 ppm to 100 ppm
What is the principle of operation
The system samples the air above the effluent/sewage continuously; this air is then passed through the sensor which reacts with VOCs and measures their concentration. The concentration is then reported via the analog output.
How is the analyzer calibrated?
The instrument is factory calibrated against toluene.
What are common target gases?
Petroleum Gas, Methane, Iso Butane, Kerosene, Ethanol, Diesel, Iso-butylene, Toluene, Acetone, Xylene, Heptane, Benzene, Methanol Mercaptan
What is the required maintenance? Is it expensive?
The instrument requires a service every 6 months to replace some low-cost components such as activated carbon filters and to make sure that there are no air leaks.
What is the warranty?
Every instrument comes with 1 year warranty from the shipment date
How does the analyzer alert the user to high concentrations of gas?
It incorporates a relay which is switched at a user definable threshold. This can be hardwired to valves/pumps and so on to stop processes very quickly. Alternatively the users SCADA system can also be used.
