Currently, the solvent swap step is a time and cost-intensive process. These processes tend to be time-intensive, slow, require a lot of operator involvement and consume a lot of solvent.  Here the Digital Processs Twin can enable the operator to make the right decision concerning the trade-off between high energy cost and increasing pressure.  Additionally, the Digital Process Twin should also be used for scaling up production.

The POC is an Online Model Deployment optimization of a solvent swap process. It involves a closed-loop control, where optimal set-points can be automatically returned to the DCS to achieve closed-loop non-linear model predictive control.
