Hydraulic Modeling

A Software Based Representation of a Pipe Network

PCE develops up-to-date hydraulic simulation models that represent the current operating performance of each systerm. We develop multiple scenario models ensuring that recommendations to system deficiencies will result in desired performance. our ability to precisely tune simulation models to represent current day operations sets us apart as the industry leader in simulation analysis.

We develop detailed hydraulic simulation models of any firewater, cooling water, steam, condensate, compressed air, process, etc., and validate these models against field data. With these detailed simulation models, PCE can quantify the root causes of reduced throughput and determine the lowest cost solutions.

Hydraulic Modeling Benefits

  • Identify and correct imbalances within each steam pressure level to avoid any unnecessary steam exhaust or letdown from a higher pressure, saving $7,000,000 at one plant.
  • Developed the additional information needed for more accurate scoping of utility systems to serve the proposed process expansion, resulting in capital cost avoidance of $10,000,000.
  • Cooling Water Systems Balance flows by reducing identified system build-ups, reconfiguring piping and restoring identified pump degradation.
  • Reduce plugging by lowering high exit temperature on the cooling water side of plant heat exchangers.

Models can be used to

  • Determine current system conditions
  • Simulate future improvements and/or expansions
  • Preliminary design
  • Simulate operational changes (pumps on/off, exchangers on/off, valuing changes, etc.)
