Process Simulation Application Example

LPG recovery unit using propane refrigeration. Simulation of BPFHE with ProSec unit operation

This example shows a process of LPG recovery in a natural gas with a propane refrigeration loop. This process is particularly inter-connected and includes several recycling loops.
Additionally, beside the implementation of the absorber module and of the refrigeration loop, this process uses a brazed plate-fin heat exchanger. This heat exchanger is modeled using ProSec, ProSim’s CAPE-OPEN compliant unit operation dedicated to the simulation of brazed plate-fin heat exchangers. ProSec allows taking into account the effect of the stacking and of the pressure drop on the enthalpy curves.
