Abstract / Summary
The use of dynamic process simulation has been established in the last few years as a reliable and effective tool to analyse transient behaviour of process systems. The transient analysis of these operations is critical to evaluate the dynamic behaviour of the compressor system and the associated control and safety systems. Modern dynamic process simulation software tools are capable to represent complex compressor systems with sufficient degree of detail to support the different type of analyses. In addition, it is usually possible to customise the model in order to allow for any application specific needs.

Abstract / Summary
During a flare release, the temperature of the flare network has a strong dependence on the relief source and on ambient conditions. During a relief of hot gases, contraction of the gases could occur due to the cool-down to ambient conditions. The rate of contraction velocity is accelerated if cooling leads to condensation of the contained gas components. The risk associated with this contraction is the depression of the header below atmospheric pressure, allowing outside air to enter into the flare system. Infiltration of air can lead to flame burn back, which in turn could initiate a destruction detonation in the system. The most common method for the prevention of air infiltration through the stack exit is to introduce purge gas. The amount of purge gas required depends on the released gas and on the gas purge composition, as well as the size and design of the flare.

Abstract / Summary
For more than a decade, refinery panel operators at Preemraff have been coached on safety and operation excellence through 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. In 2016, it was decided to extend the use of this training tool to two other existing units: the hydrogen production unit (HPU) and the Isocracker unit (ICR). In addition, the existing FCC OTS also had to be updated with recent plant changes. The authors also examine modern training methods for operators and look at how these have been successfully rolled out.

Abstract / Summary
Cryogenic distillation is the best candidate for hydrogen isotopic separation in fusion power plants. The design of the ITER’s Isotope Separation System can still undergo major changes due to its close contact with the Water Detritiation System and this will be decisive in the design of future DEMO detritiation facilities. Dynamic simulation tools are key in the analysis and design of tritium processing systems and the use of commercial simulators can be especially valuable to this end and may add capabilities in terms of standardization of industrial-scale fusion plant modeling and conjunction of operator training systems, human-machine interface and process monitoring and control. The present work proposes the use of a commercial dynamic process simulator such as Aspen HYSYS given its abilities to overcome the challenges described. This document presents the implementation of a cryogenic distillation column in Aspen HYSYS by setting the thermodynamic principles upon which the simulation is founded and verifying isotopic separation models with experimental data available in the literature.

Abstract / Summary
The realization of nuclear fusion energy is nowadays based on the concept of tritium breeding and the success of the ITER experiment. The latter relies today on a static monitoring approach to fulfill the emission limits imposed by the regulatory institutions. Artificial intelligence applications for fault diagnosis and process monitoring anticipate potential for the dynamic management of tritium in complex plant systems. This paper explores the dynamic tritium inventory management issue in complex systems, reviews the diverse artificial intelligence techniques and discusses the most promising approaches for ITER-like plant system match balance monitoring.

Abstract / Summary
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. Several compression systems boost the pressure of the permeate stream (2.5 bara) to a pressure in the range of 450–550 bara, pressure level suitable for reinjection. Many blowdown valves are installed along the compression systems, the associated pipelines and equipment. Hazard analysis did identify the potentiality for solid CO2 (dry ice) formation during depressurization (blowdown) in, basically, any section of the different process units. The formation of dry ice during depressurization constitutes a threat to the safety integrity of the system. Several simulation studies have been carried out to determine if in current process conditions the depressurization of the process sections could lead to the formation of dry ice. VMGSim, from Virtual Materials Group (VMG), was the dynamic process simulator of choice due to the availability of the APR-SolidCO2 property package, which allowed for the quantitative determination of the dry-ice formation. The dynamic analysis performed with the simulator allowed to determine the amount of dry ice formed, the time when the CO2 started to appear, and the time when CO2 melted back and disappeared. Once the formation of dry ice was confirmed by the different dynamic analysis, several mitigation techniques were planned and tested with additional dynamic simulation runs that helped to diminish the dry-ice appearance and its impact on plant performance.

Abstract / Summary
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, implementing and testing it. In order to bridge the gap between the industry’s in-depth knowledge of classical control techniques and the new process simulation features, Inprocess proposes a simulation-based course, targeting process control engineers, where the right combination of theory and practical exercises allows the meeting of such professional needs. Training could be extended to Multivariable model predictive control (MPC) topics

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.

Abstract / Summary
Operator Training Simulators (OTS) have become an integral element in 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. On the other hand, modern Integrated Control and Safety Systems (ICSS) include independent soft-controller tools to allow an exhaustive check-out of the ICSS and the OTS development. This has enabled flexible and customizable OTS architectures, which significantly reduce the development costs and maximizes the value of the OTS investment. The main focus of this article is to provide recommendations and advice to Operating Companies (OpCo) and Engineering Procurement & Construction (EPC) Companies when they embark on a tender process to procure an OTS.

Abstract / Summary
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) is aware of its operation. Improving the understanding and awareness is the goal of any training to CROs, hence, their trainings must be carried out in an environment as similar as possible to the one they will find in their work, like airplane pilots do with flight simulators, in order to be minimally qualified to carry out their job tasks. And this is the objective of the Operator Training Systems (OTS): deliver training to CROs in a replica of their working environment, maximizing its effectiveness. Matching the availability of the training facilities (comprising instructor) with the one of the CRO can be crucial in easing to achieve an on-time learning activity. That's why, in the traditional approach to the OTS, these training systems live in a training room, typically close to the actual control room they emulate. The universalization of internet connections, even in the most remote locations, and the evolution of the software technologies to support and enable mobility bring new opportunities to training systems. Those OTS systems that had to be physically deployed at every site where operators were trained can now be remote by combining some of the latest developments: e-learning standards (like the well-established SCORM or AICC), sound software applications used to develop and deploy OTS (dynamic process simulators, control system emulators...) and the latest technologies on virtualization. This distributed framework does not only facilitate scalability of the training sessions or overall system maintenance, but it also grants access to comprehensive training to more people in many different conditions, even to people in the same company that are in charge of similar processes. The return of investment in training and education is then maximized by easing the access to many more people.

Abstract / Summary
Inprocess’ experts detailed in this Oral Contribution how it is possible to save OpEx by minimizing the amount of hydrogen that is sent to the fuel network. An advisory tool, based on an optimizer put on top of a simulation model, is used by operating companies to send the correct amount of hydrogen, at the correct purity, to refinery consumers while benefiting from the one generated by producers. Simultaneously, the required external hydrogen is reduced and the one discarded to fuel network is as well minimized. The advisory tool is connected online with the plant real time database in order to regularly update the simulation model with operating data before every optimization step is launched.

In this day and age it has become necessary to seek maximum efficiency and speed in executing any process, obtaining the desired results with a minimum investment and the highest quality. For this reason, control systems have become very important, and considerable time and resources have been dedicated to studying them to ensure their efficient start‐up and operation. Thus, for a process to function within the required margins, an adequate control system must be implemented, regulated in accordance with the parameters that govern it. Within this context, a distinction is established between different types of controllers:

• Proportional (P) controllers.
• Proportional‐integral (PI) controllers.
• Proportional‐derivative (PD) controllers.
• Proportional‐integral‐derivative (PID) controllers.

Abstract / Summary
The paper describes the steps that should be taken during a flare network capacity assessment, using both a conventional approach and dynamic simulation.

The absorption process is based on the transfer of a pollutant from a gaseous current in which it is present in a high concentration, to a liquid with a low vapour pressure and a lower concentration of the compound, in which it is highly soluble. So the driving force that generates the separation will be the difference in the concentrations. Absorption may be physical if the separation is by dissolution or chemical, if the compound to be eliminated reacts to the selected solvent.

To achieve maximum efficiency, it is necessary to find the maximum contact surface between the residual gas and the eliminator liquid. In addition, the materials used to build the equipment must be resistant to corrosion, due to the acidity of the pollutants. There is a wide range of equipment designed for this purpose, including tray columns, packed columns, aspersion boxes, Venturi separators, etc. In this particular case, the study is conducted in a packed column fitted with a plate at the bottom of the column (sump) that acts like a hydraulic seal and allows the liquid level to be controlled.

Abstract / Summary
An Operator Training System (OTS) is one of the best methods to train staff in operations before a producing plant start-up. Carrying out this training before plant commissioning ensures a fast learning curve of the new process and control and instrumentation systems. Moreover, the operators can be exposed to emergency situations or process upsets that are not part of the daily operation. This will facilitate the operator response to normal and abnormal process conditions.

Abstract / Summary
Safety and productivity in processing plants depend greatly on the accurate performance of the control and safety systems, normally centralized in control rooms, through the distributed control systems and safety instrumented systems (DCS, SIS). In order to ensure the plant production, it is key to have staff well trained in the operation of such automated systems.

Abstract / Summary
Over the past 10 years the use of dynamic process simulation has been established as a reliable and effective tool to analyse transient behaviour of process systems.

Centrifugal compressor systems show performance characteristics that mainly depend on the operating point imposed on them by the process units and the connection piping around the compressor.

Large compression systems often have several compressors operating in parallel, with some of them in standby. Therefore, even in normal operation there are frquent start up and shut down operations while switching between compressors: to accommodate throughput changes, for example. The transient analysis of these operations is critical in the evaluation of the dynamic behaviour of the compressor system and the associated control and safety systems.

Abstract / Summary
Flare and relief systems commonly found in processing plants in the oil, gas and petrochemical industries are constantly under examination.

New constructions, the extension of existing plants or changes in safety regulations all require a detailed analysis of several aspects of the flare and relief system. In many cases, steady state analysis will suffice; but, more often than not, complex or marginal problems require dynamic analysis to resolve an apparently bottlenecked flare system.

This approach has recently been successfully applied to analyse and improve the blow down strategy for an existing gas utilisation plant (GUP) owned and operated by Wintershall in Libya.

Aspentech’s Industry White Paper (2011 - The content of this paper originally appeared in Oil & Gas Journal, October 4, 2010)

Abstract / Summary
The European Union 10-ppm sulfur fuel regulations present various challenges for operating and controlling refinery desulfurization units. Repsol has been using simulation to mitigate some of these challenges.

In a joint project with AspenTech, the two companies developed a rigorous steady-state and dynamic Aspen HYSYS® model of Repsol’s Puertollano refinery’s hydrodesulfurization (HDS) unit. This model was further integrated with the unit multivariable predictive controller (MPC), Aspen DMCplus®, which helped investigations of reactor conditions and operations to establish better control strategies. This paper presents an account of the project and some lessons learned.

Abstract / Summary
There are different situations in which it is necessary to re-evaluate the capacity of a site's existing flare system. In general, this is necessary following a potential increase in flare load, e.g. when:

• Relief Valves that currently blow to air and that need to be connected to the flare header,
• Changes in regulation that redefine the scenarios for which the flare system has to be designed,
• New plants that are connected to the existing flare header, or
• Throughput increase / revamps of existing plants that might increase the flare load through higher hold-up or higher heat load.

In this article, the authors give an overview of the advantages of the approach of using dynamic simulation to calculate flare loads following API 521, give guidance on when and where to apply it, and describe a case study of a recent study at BP’s Lingen refinery in Germany.

Abstract / Summary
La estimación de los caudales de alivio de presión en la cabeza de las columnas de destilación resulta de cálculo complicado debido a la naturaleza de estas unidades, donde la composición cambia a lo largo de la columna y del tiempo. En el presente artículo se compara la aplicación del método convencional y del basado en simulación dinámica para la estimación en una unidad atmosférica de destilación de crudo.
