Inprocess is an independent process simulation services and consulting company. As such, we provide the fertilizer producing industry with dynamic simulation studies to validate the operability of newly designed plants, as well as of revamped, or brownfield ones. Other than these studies, we are as well very active in the development and commissioning of high-fidelity Operator Training Simulators for fertilizer plants, combining any type of dynamic process simulator with any type of DCS and SIS provider. Thanks to these OTSs, we not only train production staff (operators and engineers) in the operability of the units but also have been helping in the startup of greenfield plants.
