brprocess joined its industrial expertise with the technology of Buchi and Digitrol / OPTEK to create the most efficient automatic analytical control project, helping to choose the best technology and application site, actively participating in calibration and interconnection to supervisory systems.


NIR-Online® BUCHI solutions enable continuous monitoring of key parameters such as acidity, humidity, color (red / yellow), phosphorus or iodine content at each stage of the process. Innovative Multipoint heads provide the most economical and efficient way to monitor strategic points in the process.

Technical specifications

  • Measurements in the near infrared range, which allows the quantification of components of interest through chemometrics, such as phosphorus, metals, soaps, acidity and peroxide, among others.
  • Unique with sensor embedded in the visible range, allowing chlorophyll and color measurement in the same equipment.
  • Data acquisition and intelligent calibration software.
  • Comprehensive diagnosis by simultaneously measuring all variables of bleaching interest.    
  • Interconnection with all PLCs and industrial network standards.


brprocess participates in the calibration startup, for five days, the most critical period for data acquisition.
Brprocess’s process engineers can even perform simpler analyzes such as acidity, humidity, soaps, etc., accelerating the filling of the calibration curve without overloading the laboratory. The calibration sequence is performed remotely via software with the support of Buchi technicians in Valinhos-SP.


It is a highly accurate color sensor used for color measurement and color changes in various industries. The sensor is designed for in-line operation and provides outstanding reproducibility, linearity, resolution and accurate concentration measurement values.
The modular design offers a high degree of adaptability to the various requirements of the process. Options include electropolished sensor bodies, hazardous locations (explosion proof), and chemical resistant materials (windows of sapphire, titanium, Hastelloy, etc.) as well as models for high temperatures and high pressures .

Technical specifications

  • Dedicated sensor for chlorophyll measurement in the bleaching outlet, in various ranges and easy calibration.   
  • Possibility of extra sensors for color, chlorophyll at the entrance of the bleaching, and turbidity (detection of earth in the oil).    
  • Simple installation and 4-20 mA outputs.



NIR 01: Crude oil (or degummed)
Measurement: FFA, P, Ca, Mg, moisture, chlorophyll
Objectives: Long-term control and reduction of acid and soda dosages; reduction of losses by incorrect dosages; pre-calculation of soil dosage, reduction of the number of analyzes and operator attention

NIR 02: Neutral oil (1st centrifuge output)
Measurement: FFA, soaps, P, Ca, Mg, humidity, chlorophyll
Objectives: Feedback for the centrifuge (through the control of soaps); feedback for the original dosages; loss control;

NIR 03: Gumming
Measurement: moisture, oil in the sludge
Objectives: Feedback for the centrifuge (interface adjustment, counterpressure, fine adjustment) to reduce losses (oil in the slurry)


NIR or visible 01: Neutral oil (or enzymatically degummed)
Measurement: FFA, soaps, moisture, P, Ca, Mg (NIR only), chlorophyll, DOBI
Objectives: Moisture control (influence on soil dosage), anticipation of soil dosage (active control of chlorophyll)

NIR 02: Neutral oil (1st centrifuge output)
Measurement: FFA, soaps, P, Ca, M, moisture only NIR), chlorophyll, color
Objectives: Automatic feedback and control of soil dosage (passive control of chlorophyll and color), phosphorus adjustment, anticipation of the deodorization profile

 Aqueous Degumming

  • Systems can be installed to control the phosphorus at the exit of refined oil, or loss of oil in the gums.
  • Every 5% oil in the gums unless it can be controlled by automatic adjustment of the centrifuge interface (insoluble in acetone) equals 0.1% of additional losses that can be saved.
  • Each 50 ppm of phosphorus delivered “free” to the customer equals 0.15% of losses (+ 33% of drag) = 0.2% of additional losses that can be saved by keeping the oil always within specification limit, eg , 200 ppm.
  • Enzymatic degumming processes with PLC – possibility of enzyme control from measurement of variation of diglycerides.
