Octane monitoring systems

March 2007 Analytical Instrumentation & Environmental Monitoring

Complete Octane Monitoring Systems (COMS) from LT Industries (LTI), combine near infraRed (NIR) technology with the power of microprocessing for reliable, precise and virtually maintenance-free composition determination of petroleum refining processes on-line, in realtime.

Using a fibre-optic probe inserted into a selected test point, COMS determines multiconstituent concentrations and properties without sample extraction and mechanical preparation required by other sensor technologies.

The unique, fibre-optic based probe meets intrinsically safe guidelines. COMS is connected to the probe by fibre-optic cables, and the entire system is rugged and environmentally safe. The non-destructive sampling technique is designed for Class 1, Div.1, Groups C through G hazardous environments in accordance with NEC and NFPA 496 codes. COMS outputs can be used for closing the loop to control the process unit.

Based on LTI's industrialised Quantum 2000 Process Analyser Series, COMS helps increase operating unit efficiency through rapid analysis and data output - one full report in less than 30 s. This is achieved with a highly customised, integrated systems package with high uptime and no solvents or operator dependency.

Octane Analysis Systems are calibrated to monitor, measure and provide realtime data output of octane number (RON and MON), oxygenates (MTBE), RVP, % saturates, % aromatics and benzene.

Installations include measurement for control of the FCC, MTBE, Blender, Aromatics Olefinics and Reformer units. Other applications include Cetane Number in diesel fuels and blending of lube oils. COM's fast scan multiplexer option can support up to 10 stations with complete analysis for all channels.
