Chemical monitoring
Chemical Monitoring at the Power Plant traditionally to account to scientifically uninteresting problem. Of course a some new device used, but on the practice big difference to comparison to time of middle of 19-century it's don't coming. In order of that we would be keep data analysis mainly. Our interest is collect/save/manage Chemical Data at the Power Plant using so called Laboratory Information Management Systems (LIMS) - a generation of Electronic Lab Notebooks and use Applications to LAN (Local Area Network) Server to remote access to check for supporting optimal and safety exploitation of main equipment on the Power Station.

At this calculation shown very simple, but more than important fact about small influence on the pH value of Dioxide Oxygen (*normal* pH value NOT GUARANTED small concentration of CO2).

One different is at here - 3 parameter to calculation. Main problems to use chemical recalculation are:

  1. math problem of stability of numerical solutions of the ordinary differential equations;
  2. large difference in the data range(from 10-14 till to 1010 );
  3. properly using modern numerical methods for (fast enough and suitable to the computation on the relatively slow machines which of still in use in the most Chemical departments at the Power Plants).

There is to shown short issue about relation between pH and Conductivity of diapason.

On example of recalculation of the Drum Boiler Water is demonstrate it's relation.

If You have possibility to check Log-Sheets-Books at the Chemical Department by the Power Plant - it's to found many mistakes and elementary incomprehension so simple and important data of. I'd to check graduate specialists from reputable internationally known of Consulting/Insurance/Engineering Companies who don't to find nothing special in a some of absurd and ridiculous of lab data.

In this calculation is displyed why, for example is so funny pH less than 6 to found in drum boiler water when Conductivity in 0.3-0.9 mkCm/cm. Check on the picture - also is so many of possibilities to print the same absurd results, likes pH=7.5 K=0.95 mkCm/cm...

This demo give possibility to fast and enough accurate to evaluate Chloride concentrations - what's hard or impossible to another methods using in the practice day-to-day exploitation...

At the next time we would publish demo of more associated to the volatile method of boiler watertreatment and to phosphate too. We are still looking for co-operate in developing of software to the Chemical Monitoring and Manage of Main processes at the Power Plant to the prevent problems of the corrosion damages and lost effectively and safety of exploitation due to of deposits presence.
