1 MANAGEMENT OVERVIEW

Having examined the data sheets applicable to the oil in water analyzers, Advanced Sensors

propose the use of its EX-100 / 1000 model. This unit is a side stream analyzer that uses

fluorescence measurement for the oil in water ppm.

Where provision of the units in the format of in-line probes is deemed essential, then this can

be accommodated using the in-line probe version of our analyzers.

 Advanced Sensors has chosen this solution as fluorescence is the best measurement

technique for Oil in Water PPM calculation.

1.1 EX-100 SIDE STREAM ANALYZERS.

The Side Stream analyzers (EX-100/1000) are very suited to end of process monitoring – that is,

measurement of produced water immediately prior to discharge or re-injection. The side stream

analyzers take a feed from a main source and provide a continuous ppm value (using

fluorescence). The output of the analyzer can be back in to the process or to a drain.

EX-100 / 1000 has the following benefits:

1) There is NO regular maintenance required and

2) In addition to the continuous on-line readings, samples can be taken periodically by closing the

valve, homogenising the sample (using the ultrasonics) and taking a highly accurate uniform

reading. This is an automatic process – configured to meet the customer’s requirements.

2 TECHNICAL BRIEF

2.1 THE PRINCIPLE OF MEASUREMENT – FLUORESCENCE

The measurement technique incorporated is laser-induced fluorescence. The transducer sensor

head and inline probe is a patented combined Optical and Ultrasonic component. In the side-

stream versions, the EX100 and EX1000, the water passes through a measurement chamber

(300mL), within the chamber there is a small sapphire window used for measurement and a

larger sapphire window for viewing the inside of the chamber.

The laser passes through the smaller sapphire window to excite the water sample, the

fluorescent properties are captured via Optical fibre light guides and taken to:

Data Logging

The operating system is built on the globally recognized Windows operating system, offering a

familiar environment for fast and easy access. The EX100/1000 captures and stores all

measurement every second and can store greater than 10 years of logs. They are stored daily as

Microsoft Excels files. The data logs contain configuration information, measurement of oil

content and temperature.

Easy Installation

The side-stream EX100/1000 has been designed for ease of installation. The unit is delivered

complete, mounted on a stand (316L stainless) fitted with a flow valve and ready to go.

Take any of the analyzers out of their delivery container, wire the mains power, plumb and turn

on, the analyzers will measure immediately. The EX100/1000 are EX d rated and do not require

purged air.

EX1000 with Spectrometer

The Spectrometer is invaluable when the analysis of the water composition is required.

One of the most challenging aspects of measuring oil in water is when the oil present in the water

changes in composition. Other oil in water analyzers that have attempted to address this

challenge, use a manual interface that will ask the operator to select the oil type that you wish tomeasure, this is nearly an impossible task, as they cannot supply the tools to identify which oil is

currently present in the water.

The EX1000 has an inbuilt spectrometer that takes the optical fingerprint of the oil. Should the oil

type change, the analyzer will automatically detect the change and select the appropriate

calibration file to provide consistently accurate measurement. This feature is unique to Advanced

Sensors analyzers.

The Spectrometer logs can be examined should an anomaly occur. By examining the spectra

logs before, during and after an anomaly, the nature and cause of the anomaly can be

determined.

The online spectrometer can also be used to detect changes in produced water composition,

which is useful in selecting process chemical and optimizing the chemical dosage.
