The MOD-8000 online process analyzer is designed to analyze the composition of process fluids. Using Magnetic Resonance (MR) spectroscopic techniques, it can detect the presence and the concentration of chemical constituents in a process stream. By utilizing exclusive software, it provides closed loop supervisory control of a process unit. It has an extensive range of applications from light Naphtha streams to heavy Crude oil. Typical user benefits comprise increased throughput, better process control, timely detection of off-spec product, and lower operating costs.

Highlights of the New System

  • New magnet design (enhanced long and short term stability; less sensitive to temperature)
  • State of the Art electronics (smaller foot-print; complete integrated PCB for Shim & Heater control; digital RF & Acquisition – improve SNR)
  • New concept of Process Probe (the entire pipe goes through without contact with the system; much better temperature insulation; higher Q i.e. better sensitivity)
  • New software (includes new algorithm for standard and global models; fully automated process capacity; extensive remote diagnostic capabilities)

System Key Advantages

  • Real time, continuous flow-through stream analysis
  • Chemical and physical analysis in dense and opaque materials
  • Multi-variable analysis by a single instrument and from a single sample
  • Linear Spectral Response across broad range; models can be extrapolated accurately
  • Stable, homogeneous magnetic field, no fringe field
  • Minimal maintenance achieved by using no-moving parts
  • Built-in reference for measuring chemical shifts of all process components
  • Automatic shim control ensures uniformity of magnetic field during measurement
  • Built-in manifold valves provide convenient purge, drain and vent connections for cleaning sample line
  • Local and remote system display, operation and supervision
