Calcium analyses at ppb level on a
chlorine plant!
Electrolysis of brine requires Ca levels in solution to be low: break through of Ca later will cause major process upsets down stream, whilst too early replacements of membranes are also undesirable
Electrolysis of brine requires Calcium levels in the solution to be low: break through of Ca at the brine purification stage will cause major process upsets down stream, whilst too early replacements of membranes are also undesirable The maintaining of low Ca levels in the brine solution is very important so as to avoiding the premature replacement of the membranes and loss of valuable production time down-stream

On-line gas scrubber analysis
Gas scrubbing to remove particulates and noxious gases is one of the most common process units - on-line analysis is possible to bring the laboratory out to control the plant!
Process chemist needed for southern UK sales
As with all expanding companies, the Metrohm Applikon Division is seeking an additional member for their sales team in the south of England
Hence the requirement, to have this analysis done frequently, to be able to timely monitor any break through of calcium, and alert process operators is highly desirable! The analysis of low ppb levels of Ca requires exceptional skills: a few ppb's of Ca are easily being picked up by taking grab samples and analysing them in the laboratory but this could lead to a high analysis result and false alert due to the lag between sampling and analysis.
For these reasons attempts have been made to put the analysis on-line but in the past this has been difficult due to long term sensitivity or crystallisation problems caused by the heavily laden brine solution.
Applikon have produced the best option for this application on-line using the Applikon Process Colorimeter ADI 2015, which truly mimics the laboratory test and delivers comparable results.
The ADI 2015 sturdy design and operation are obtaining amazingly long up times of the Analyser, brought about by:.
*Complete separation of the sampling device and measurement vessel, allowing independent washing cycles.
* The use of a dipping probe colorimeter, allowing a reference measurement to be taken before each analysis.
* The use of a high precision burettes to dispense the concentrated indicator solution.
The 2015 Process Colorimeter is well geared up for the harsh conditions at a chlorine production site: it is housed in a rugged steel shell, heavy duty coated and comes with a transparent door to allow visual inspection but denies unauthorised access.
Besides providing accurate results the 2015 also can perform an automatic calibration, either on the basis of a set time or by a previously set condition (if-statement). Request a free brochure from Applikon Analytical ...
