Chemical plant system modeling experience based on the use of largely validated commercial modeling tools such as the Aspen HYSYS is adapted and exploited to develop numeric routines for unitary isotopic operations, including permeation, cold trapping, reversible absorption, and cryogenic distillation, for the ITER tritium plant systems.
For more than a decade, refinery panel operators at Preemraff have been coached on safety and operation excellence by hands-on training with an operator training simulator (OTS). The fluidised catalytic cracker (FCC) at the Lysekil Refinery was the first refinery unit for which an OTS was built.
The authors present the results of the collaboration between Espindesa and Inprocess in order to develop a software tool that acts as a digital twin of a real nitric acid plant.
Inprocess authors discuss the application of dynamic simulation to analyse potential trips of the HIPPS system at the flare header of a central processing facility during trunkline pigging operations.
The associated gas of an oil-producing field in off-shore Brazil is treated to remove water, hydrocarbon condensate, H2S and CO2. For environmental reasons, the CO2-rich permeate stream from the gas treatment process must be re-injected into the reservoir.
Operator Training Simulators (OTS) have become an integral element of the Operator Competency Development Programs of the process industry. The dynamic simulation technology has evolved from the early days, incorporating new training functionalities and communication capabilities.
In a recent FPSO development project offshore West Africa, a lifecycle modeling approach project, ending in a direct-connect Operator Training System with Aspen HYSYS Dynamics, was used for process design and control narrative validation, procedure verification, ICSS check-out, control room operator training and support for FPSO start-up operations.
Producing plants must be safe and reliable. Plant Safety is strongly dependent on how well people responsible for running the facility (control room operators, CRO) are aware of its operation.
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.
The definition of a Control System in Chemical and Petrochemical Plants requires specific know-how with the target of optimizing and improving existing systems and designing new ones. When designing a system, it is necessary to follow some basic steps such as modelling the system, analysing such model, designing the system/controller and finally
