NIRSPEC UAN ANALYZER ON-LINE ANALYSIS OF UREA AMMONIUM NITRATE COMPOSITION - INCLUDING BIURET -

NIRSPEC UAN PROCESS ANALYZER The state of the art solution for on-line analysis of the composition of Urea Ammonium Nitrate. NIRSpec UAN analyzer can measure not only the concentrations of the main UAN components: Urea, Ammonium Nitrate and Water, but also the concentration of the unwanted by-product Biuret, which is becoming an increasingly important quality parameter of UAN. Accurate continuous/real-time measurements and the unique capability of measuring the concentration of Biuret enable a better control of the quality of the UAN in the production process. The analytical technology is...

SYSTEM OVERVIEW

PRODUCT FLOW SYSTEM OVERVIEW The optical design of the analyzer is such that it has a single linear optical path from the source directly to the detector. The light is collimated, transmitted through a sample and focused/directed straight into the spectrometer.

FEATURES On-line measurement of 4 UAN components: Urea, Ammonium Nitrate, Water and Biuret Durable industrial design Accuracy up to 0.1% wt. Turbidity compensation Compensation for product temperature variation Low sensitivity to optical window fouling Automatic washing/cleaning of optical windows Operating pressure up to 10 bar Operating temperature up to 120 °C RS485 MODBUS interface IP68 rating

BENEFITS Continuous on-line quantitative analysis of UAN for better process (product quality) control. Measurement of 4 UAN components: Urea, Ammonium Nitrate, Water and Biuret. Eliminates time-loss and cost for sampling and laboratory measurements. High accuracy, repeatability and stability. Low operating and maintenance costs. State of the art (proprietary) multivariate calibration with compensation for product temperature variation and for turbidity. Large transillumination area, hence less sensitivity to optical window fouling, better repeatability.
