1. Summary: Key advantages of LT’s PetroScan NIR technology• Complete integration of predicted properties into your Distributed ControlSystem (DCS) for use in Blend Ration Control and Blend Property Controlpackages• Use of the blend’s recipe from the DCS to control which components will bemeasured in the blend• Prediction of Olefins, Aromatics, Benzene, Octane Numbers (Ron, Mon andRoad), Distillation Points, Oxygenates for Blender’s Output and componentstreams to meet the requirements of the reformulated gasoline complex modelmarket.• Laboratory Unit with identical optics to develop calibration and LT’s uniqueTRANS calibration transfer software to transfer the calibrations to the processanalyser. This is a key factor to speed the calibration development.• The Absolute Reference Cell (ARCell) is LT’s patented dual-flow sampling cellto provide robust self-referenced measurement.• Optical Multiplexer provides multiple measuring points per analyzer, reducingthe cost per individual measurement.• Internal In-line polystyrene wavelength calibration standard providescontinuos wavelength accuracy.• Sample Conditioning of the Blender’s Output and automatic outlier capture inall components streams.• Modem support for instant remote assistance anytime during the project.- 3 -
