COURIER® 30SX

Introduction

Courier 30SX is a new member ofthe proven COURIER 30 family ofanalyzers. It is optimized to servethe special needs of solventextraction and similar processes.Outokumpu�s experience frommore than 50 solution analyzerinstallations since 1981 has beentaken into account when designingthis new on-stream analyzer system.

The COURIER 30SX systemanalyzes samples of processstreams from solvent extractionprocesses, using the field-triedCOURIER 30 family X-raytechnology to make elementalanalyses, supplemented by OTI 99titrators to analyze supplementaryionic contents, such as acid content.

Samples are taken from the processusing fast loops to ensurecontinuous flow and availability offresh sample. Samples areintroduced to the analyzer via amanifold which has built-in de-aeration and thorough flushingfunctions.

Analysis results from Courier 30SXand titrators are sent to a processcontrol system, e.g. PROSCON2100, via a single communicationlink using established protocols.

Typical pre-installed industrial environment shelter for Courier 30SXwith OTI 99 titrators.

Operator Station

Courier 30SX has an interface fortransferring information betweenthe analyzer and OPERATORSTATION. The Operator Station isused for system configuration andcalibration. It can also be used forprocess data display, if there is noDCS system on site.

Third party DCS system

Optional serial line connection isavailable, based on MODBUS RTUprotocol for reading processanalysis results and analyzer status,and control of sample sequence(Bypass, Measurement Request).

PROSCON 2100automation system

For transferring information to andfrom Outokumpu�s PROSCON 2100system Courier 30SX has a standardinterface.

Sample handling

The sample handling of theCOURIER 30SX is adapted to theconditions of heap leach - solventextraction - electrowinningprocesses.

Samples taken from process pipes,or mixer-settler end-boxes flow infast loops to the analyzer location.The sample flow rate and pipe sizeare chosen to ensure that thesample temperature remainssufficiently high in the sample pipe.The pressure of the sample feed tothe analyzer is recommended to beabout 0.75 bar, minimum 0.5 bar .Samples have to be free of solids.

Samples are taken through normalball or diaphragm manual valves.(shut-off valve and a valve forflushing the pipe with water whenshutting down sample flow areneeded).

The pipe size and flow rate varyfrom about 5 - 10 l/min in 10 mmpipes for samples from processpump pressure pipes (pressure upto 2.5 bar) close to the analyzer

Number of samples

The system is flexible, and can takesamples from up to 16 processstreams. Organic samples can bemeasured in the same analyzer asthe aqueous samples.

Analysis cycle

The normal analysis cycle is 2minutes per stream for X-rayanalysis, samples containingentrained air need de-aeration andthe sample cycle is a little longer.

On-line titration can be integratedin the COURIER 30SX system. Thetitration of acid, or analysis ofchloride takes 5 to 7 minutes. Thesystem automatically allows for thisand feeds every second or thirdsample to the titrators so that thefaster XRF analyzer is not sloweddown.

Calibration

Outocal calibration software is usedto manage the calibration of Courieranalyzers.

Analysis accuracy

The COURIER 30SX can distinguishand measure very small quantitiesof trace elements in strongelectrolytes. For instance manganesecan be measured from 5 mg/lupwards (3 standard deviationdetection limit), iron and cobaltfrom 2 to 3 mg/l.

All levels of acid content met in theprocess can be titrated on-line,and chloride can be measured from10 mg/l upwards.

The accuracy (repeatability) ofsuccessive measurements is ± 1%for X-ray analysis and titration oflarge contents of metals, acid andchloride.

Courier 30SX excites thesample in flow cell using lowpower X-rays. Atoms in thesample react by emittingfluorescence radiation whichis characteristic to eachindividual element in theperiodic table.

Courier 30SX uses the samehigh resolution wavelengthdispersive analyzertechnology as highperformance laboratoryanalyzers. This minimizesspectrum overlaps andmakes analyzer calibrationeasiear and less frequent.
