VRTech, working together with optimization team from REFA, performed the modeling, simulation and validation of a depropanizer column using dynamic rigorous models of the industrial process. After the modelling the simulation was integrated with REFAP's SCADA system through the EMSO-OPC module, publishing the simulation data at the SCADA system. VRTech also presented a training course at EMSO simulator for the REFAP's team.
