The ID-200 Series Interface Detectors are used for interface measurement and control in all types of liquid/liquid and vapor/liquid separation processes including emulsions and foam.

The ID-200 series

The ID-200 Series Interface Detectors are used for interface measurement and control in all types of liquid/liquid and vapor/liquid separation processes including emulsions and foam. A wide range of models, process connections, and output options are available for the control of a variety of process installations such as Tanks, Decanters, Dehydrators, Desalters, Coalescers, etc. The ID-200 Series advanced control capabilities can be used to automate upset responses, antifoam and demulsifier chemical feed systems, and eliminate cross-contamination of separating phases.

The Waste and Cost of Slop Oil

With Crude oil currently being under $100/bbl, poor oil and water interface/separation control, refineries accidentally dump crude oil and/or refined product to the Waste Water Treatment System (WWTS) on a regular basis. The Oil is not actually lost but is recovered in the WWTS/API Separator. However, it is no longer virgin Crude Oil or Refined Product – the lights have evaporated, the product has been sheared and emulsified by pumps & contaminated with solids. In effect, it has been reduced to recovered SLOP OIL.


A typical refinery today will accidentally dump 0.5% to 1.0% of its total throughput to the WWTS because of poor interface/separation control. For a 100,000bpd refinery, this equals 500 to 1,000bpd of recovered SLOP OIL.

Reduction in slop oil


*Example from a US Refinery

By installing Agar ID-200 Interface Detectors, a US refinery was able to reduce its total HC being dumped to the WWTS by 82% with better interface/separation control (see attached Hydrocarbon Processing article). An 82% reduction in the amount of SLOP OIL being generated is equal to £1,990,424/year in savings/additional profit. Not just for the first single year, but continuing year after year.

Founded in 1980, plus used by all major oil companies around the world, Agar Corporation is a main pioneer of non-nuclear, versatile, multi-phase flow meters used to optimize oil well testing and production. Agar provides innovative solutions for applications such as: heavy oil well testing, waste water treatment, automatic tank dewatering, desalters and gas liquid foam control.
