NEXTChem Process Analyzers, LLC.
On-Line Refinery Caustic
Industry: Petrochemical
NEXTChem Process Analyzers provides the first complete, chemical analysis and process
control on-line analyzer. The automation of these analyses and process control improves product
quality and lowers production costs.
Sample Filtration is eliminated, in samples with high solids. For
samples requiring dilution <2mm particles can easily be handled. For
non-dilution samples <6mm particles pose no problem. No other
system can match this rugged design.
The OMNIChem Series Analyzers can provide accuracy only matched
by the most precise laboratory equipment. Our reagent precision
pumps deliver titrants with + 0.001 mL reproducibility. Potentiometric
analyses are utilized thus eliminating errors caused by electrode drift.
Analysis of Refinery Caustic
Refinery Caustic is determined by an acid / base titration. The endpoint is found with a glass pH
electrode.
