MONITOR™ Program

The MONITOR computer program determines and analyzes fouling trends in refinery heat exchanger networks.

Heat exchanger fouling has a direct impact on  bottom line profitability. The immediate result is higher operating costs and lower throughput. 

Regular use of the MONITOR program provides reliable and consistent information on fouling trends, identifies the sources of fouling and points to the correct remedial action.

The range of remedies is well known:

  • Optimize cleaning cycles for preheat exchangers
  • Change splitter ratios
  • Add and monitor chemical fouling
  • Control program

Choosing the right  remedy at the right time is the challenge.  The MONITOR program, with its rigorous thermodynamics, industry standard heat transfer correlations and time-line trend analysis, helps you make that choice.
