Arjay Engineering Process and Environment Control Systems

Arjay Engineering designs and manufactures parts per million (ppm) oil-in-water analysers, monitors and control instruments.

Products are used in the hydrocarbons industry for upstream and downstream wastewater, oil/water separator monitoring and control in applications such as stormwater, oil water knockout treaters and bilge liquids.

Arjay can provide custom panels and systems to suit the client’s requirements. Speciality racks can be designed to accommodate accessories and support instrumentation for the application.

ppm oil in water analysers, monitors and spill and sheen detectors

Arjay Engineering provides ppm oil-in-water analysers, oil on water detection and oil/water separator interface and emulsion alarms.

For ppm monitoring, UV fluorescence is typically used for industrial applications. The Arjay light scatter approach is an affordable method for cooling water leak alarms. Interface and oil thickness monitors employ a capacitance technique for reliable low-cost monitoring.

The HydroSense 2410 is used for produced water monitoring. This analyser uses UV fluorescence to target aromatics in water. Through a simple site calibration, the aromatic response is correlated to a total oil reading in ppm.

Oil/water separator controls and oil spill alarms for hydrocarbon storage tanks

The Level-Ease series of capacitance controls are used to monitor and control the oil-water interface levels within tanks. The robust probe design does not have optics or moving parts that can foul.

High pressure and a wide temperature range make this series an ideal choice for monitoring and control of processes, pumps and valves.

The Arjay float sensors continuously scan for oil separated to the surface of the water. Simple on/off alarms and oil thickness monitors are used to alert when the accumulation of surface oil requires attention, or to shut down pumps that may inadvertently pump oil to drain.

Solid and liquid level control systems for the hydrocarbon applications

The Arjay capacitance level controls have a lengthy and proven background of reliability. Arjay Engineering offers basic probe mounted transmitters and on/off switches.

The Level-Ease series is available to meet level display requirements and has a remote control with multiple relay points and proportional outputs.

These can be coupled with any Arjay probe for continuous and point level applications of liquids and solids.

Bilge and ballast water monitoring for the hydrocarbon industry

Any product in the Arjay HydroSense series is suitable for leak alarming. The 2410 is the industrial non-contacting design for untreated or turbid wastewater.

The 4410 is a more economical choice and can be used for filtered wastewater or water that is free of suspended solids and turbidity. For bilge and ballast oil content separator applications, the 2410 carries IMO approval for MEPC.107(49)

Heat transfer systems can contaminate the water with oil through pinhole leaks. The Arjay controls will monitor for these leaks, and the HydroSense 2410 specifically targets petroleum oils where animal or vegetable oils may be present and trigger an unnecessary alarm.

The HydroSense 4410 Light Scatter model will respond to any free oil type.

Approvals and certifications for petrochemical instrumentation

There are many approvals and certifications carried by Arjay products. These include ISO 9001:2015, ABS (American Bureau of Shipping), IMO (International Maritime Organization), CSA, ATEX, IECEx, UL, CE, CRN and ABSA.

Certain products can be used in Zone 0, 1 and 2, division 1 and 2 hazardous locations through their third-party approved explosion proof packaging (Ex d), non-incendive design (Ex n), intrinsic safety barriers (Ex i) or by a purging pressurisation option (Ex p and EEx p).
