LIBPF™ (LIBrary for Process Flowsheeting) is a flexible technology to model continuous industrial processes at steady state. For more information please visit the library website.

This is the automatically-generated documentation to the full, low-level LIBPF™ C++ API used to develop process models of continuous industrial processes.

This API provides over 300 classes:

Quantities with physical units of measurement
Pure components, food components, biomasses and custom components
Physical, Chemical and Transport properties
Material streams with unlimited phases (vapors, liquids, solids)
Vapor-liquid equilibria according to ideal laws, equation of state of Kwong, Redlich and Soave or Peng and Robinson, or activity coefficient method NRTL
Reactions and equilibrium reactions
Concentrated parameters unit operations:
- Mixer
- flow Divider (tee)
- flow Multiplier
- fixed-yield Separator
- ideal phase separation (Splitter)
- Flash drums
- Fixed-yield or equilibrium stoichiometric reactors
- Isentropic Compressor/expander
Hybrid-unit operations:
- Reactive two-flow heat exchanger
- Reactive multi-flow heat exchanger
- Fuel cells: molten carbonate, solid oxide (protonic / oxygen conducting and combinations)
- gas separation membranes
Multi-stage combinations of the above to represent distributed unit operations:
- MultiStage: 1-D combinations of concentrated parameter unit operation, co-current or counter-current
- MultiStage2D: 2-D combinations of concentrated parameter unit operation, with spiral, co-flow, counter-flow, cross-flow and arbitary flow patterns
Flowsheets where unit operations are connected with streams and controlled with feed-back or feed-forward process specifications.
