The Multisensor MS1220-S is a high-range online oil-in-water analyzer that measures hydrocarbons and volatile organic compounds in water from 1 to 200 ppm (mg/l). It is designed for industrial and petrochemical process water – cooling water, refinery influent, phenol-bearing discharges and oily effluent – and measures from the headspace without contact with the water. Akan Industrial and Automation supplies and commissions the MS1220-S in Türkiye as Multisensor Systems dealer.
Where is the MS1220-S used?
Oil in cooling water
A corroded heat exchanger, a leaking pump seal or an accidental spill can contaminate a cooling water circuit with hydrocarbons. Continuous monitoring detects the leak early, before fouling, product loss or a contaminated blowdown discharge.
Refinery and petrochemical process water
Wherever water and hydrocarbons are mixed – in refineries and petrochemical plants – the water must be treated before reuse or discharge. Measuring the hydrocarbon load of the influent lets the treatment be optimized.
Phenols in discharge water
Phenols are feedstock for plastics, resins and pharmaceuticals but are subject to strict emission limits. The MS1220-S can be calibrated for the compounds of interest to track them in discharge water.
How does it work?
Water passes through a stainless steel sampling tank, volatiles move into the headspace and the headspace gas is passed across an electronic-nose sensor array. As the sensor never touches the water, high oil loads and suspended solids do not foul it. Because detection is not based on fluorescence, the analyzer responds to fluorescent and non-fluorescent compounds alike.
