Process simulation is a technology used in many areas and project phases. Its usage ranges from the design stage of a plant (initial concept and front end engineering) to assistance in daily plant operations, including planning, optimisation and monitoring. To a certain extent, the simulation lifecycle is similar to the lifecycle of a process plant, bringing support and value to multiple stages in the lifetime of a process plant.
Using Simplot Phosphates’ ammonia process plant in Rock Springs, Wyoming, USA, where dynamic process simulation has been used, as an example, this article focuses on the implementation and benefits of an operator training system (OTS) for the plant. It will explain this specific use of the OTS, as well as outline some experiences and results from the point of view of the three parties involved in the project: the licensor and engineering company in charge of the construction, Linde; the plant owner and operator, Simplot Phosphates; and the simulation services provider in charge of developing and deploying the OTS, Inprocess Technology and Consulting Group, S.L.
