HEAT EXCHANGERS

Custom and off-the-shelf heat exchangers are used throughout the oil and gas industry.  Sizing or designing the right heat exchanger can have a significant effect on the safety and performance of your systems.  Flownex excels at this type of trade study and design exploration. 

Typical applications include:

  • Calculating heat transfer and pressure drop for
    various geometries: finned tube, shell and tube,
    tube-in-tube, and plate heat exchangers
  • Calculating the heating or cooling requirement
    for various processes: 
    • Evaporation
    • Condensation
    • Temperature control
  • Calculation of natural circulation evaporatorsʼ recirculation rate
  • Simulation of transient behavior for startup, shut-down, or process upset conditions
  • Calculation of temperatures and boiling pressure drop
  • Calculation of metal temperature change rates during transients.

LIQUID HANDLING SYSTEMS

One of Flownex’s sweet spots is simulating complex liquid handling systems, just like the collections of pipes, valves, pumps, and tanks found in oil systems. Add in a viscous liquid and multiple phases, and Flownex shines even more. 

Typical applications include:

  • Calculation of pressure drop
    for gases or liquids
  • Pump and pipeline sizing
  • Pump performance adjustment
    for viscosity
  • Sizing of control valves and orifices
  • Design of liquid distribution systems
  • Flow balancing in branching networks
  • Analysis of transient events like pressure wave (water hammer/ surge) propagation
  • Control philosophy development and testing using the built-in PLC function block diagrams
  • Sizing of pressure safety valves
  • Simulation of a valve failure event
  • Calculation of heating or cooling
    requirements for various processes
  • Heat loss/pickup calculations
  • Insulation sizing.

DRILLING MUD PUMPING SYSTEMS FOR OIL WELLS

Drilling mud is a non-newtonian fluid with unique characteristics that normal simulation tools can’t model.  But Flownex was built from the ground up to handle those corner cases where you are moving something other than water or air.  that is why engineers designing pumping systems for oil wells leverage Flownex to design and optimize their solutions. 

Some typical applications are: 

  • Calculation of Non-Newtonian fluid pressure drop
  • Balancing of flow in branching pipe networks
  • Assessment of pressure pulse transients

FIRE PROTECTION SYSTEMS

A secondary fluid system in many oil and gas applications is fire protection. Regardless of the fire suppressant material you are using, Flownex has the capabilities you need to design a safe and maintainable system that can perform when and where you need it. 

Typical uses include:

  • Pump, pipe, and tank sizing
  • Sizing of nozzles and orifices
  • Flow balancing

Testimonials

“I am not aware of any other tool with which I could have obtained the required results in such a short time span. Part of the success must undoubtedly be attributed to the prompt and high level support provided by Flownex® International almost daily in answering all my questions and offering suggestions throughout this very technically challenging simulation. The support fee has been paid for with this one project!”
