Bayer Liquor Analysis by Infra-Red (BLAIR) is a new technology invented and developed at Central Chemical Consulting. It is a fast and accurate analysis for process control in alumina refineries, and has many advantages over existing titration methods.
Comprehensive analytical information
BLAIR uses spectroscopic measurements to provide a complete Bayer liquor analysis for the following quantities: alumina, total caustic, total alkalinity, carbonate, sulfate, chloride, derived caustic ratios, total organic carbon (TOC), organics breakdown ratio (Borg), oxalate, malonate, formate, acetate, succinate and liquor density. All this information comes from a single BLAIR measurement on one small sample.
Fast and convenient
A complete BLAIR analysis takes less than three minutes for a manual measurement, or five minutes in an automated system. There is no need for dilution or the addition of other reagents. There are no messy titrations, and few moving parts.
Consistent results
BLAIR has industry-standard precision and reliability. Testing results show a typical relative standard deviation (RSD) of 0.5% for repeated measurements of alumina, caustic and soda.
Process control
Specifically designed for alumina refineries, BLAIR provides rapid, rich information on species in Bayer liquors.
BLAIR applications
- Quality control measurements in the alumina process laboratory.
- At-line process control measurements.
- Bayer research requiring fast and comprehensive results.
Value
BLAIR offers the lowest cost method for collecting engineering data on the alumina process, by combining many analytical functions into one streamlined instrument.
