Catalytic reactor design and analysis
Careful design of catalytic reactors, the workhorses of the chemicals industry, can reduce both the cost and risk associated with new designs, as well as reduce ownership costs significantly through better catalyst performance. This webinar shows how it is now possible to perform detailed design of multitubular reactors taking into account multi-scale effects - from catalyst pore to industrial reactor scale - within a flowsheeting simulator environment.

Easy design and operational analysis of pressure swing adsorption systems
Adsorption process development is typically a slow, iterative procedure where the goal is restricted to confidence rather than optimisation. Engineers must rely on pilot plant testing and design heuristics because legacy simulation software is unsuited to the flow reversals, fast transients and discontinuities inherent to cyclic separations. Equation-oriented dynamic modelling can solve cyclic separation systems rapidly and robustly, allowing engineers to answer design and operational questions based on accurate predictions.

Modelling distillation process dynamics in gPROMS ProcessBuilder
Typically, distillation columns are designed and operated based on time-invariant (steady state) analysis. In reality however, distillation processes are continuously subject to disturbances, caused by variations in feedstock, changes in product requirements, the availability of utilities, and so on. Dynamic modelling is a key technology for optimising column design and operation. It can be used to understand the effects of feed and product quality changes, periodic feed upsets and abnormal operation, and then to design and tune control schemes capable of dealing with such disturbances.

Optimising styrene plant operations
The performance of styrene plants is highly dependent on chosen operating conditions, the availability of utilities and current market price of ethylbenzene, styrene, toluene and benzene. Styrene production plants are typically integrated facilities, with complex reactors, significant material re-cycles and heat integration, which poses considerable challenges for process optimisation. This webinar explains how a rigorous approach based on advanced process models, now available off-the-shelf in the gPROMS ProcessBuilder advanced process flowsheeting environment, can help identify real additional value in operation.

gPROMS Utilities: Advanced utilities optimisation for process plants
Plants consume fuels, electricity and steam in time-varying quantities, and via multiple routes. The process plants themselves can generate steam and fuels, electricity can be sold to the grid and the prices of the various components can change hourly. Added to this complexity are day-to-day changes in major equipment availability. PSE’s gPROMS Utilities suite helps find a way through the maze by applying rigorous optimisation technology to process models of the utility system, taking into account demands, prices and availability, to find the economically optimal operating profile for any situation.

Whole plant optimisation for chemical plants
In the production of propylene oxide and styrene monomer, a large part of the cost of the process (and hence its profitability) is influenced by the capital cost of the reactor and separation equipment, and the energy requirements for large distillation columns, which may be required to operate at high reflux for close-boiling mixtures. This webinar describes two process design case studies aimed at improving process economics, in one case leading to identified savings of 10s of millions of euros per year.

Advanced applications: Cyclic separation
Periodic adsorption processes, such as PSA or TSA, are widely used in industry as energy-efficient alternatives to cryogenic or absorptive separation technologies - for example in the production of high-purity hydrogen, the upgrading of bio-based gases and the separation of close-boiling mixtures. Until now, the tools and methodologies for rigorous design of these processes have been limited, and this has posed challenges for the effective design of adsorption systems themselves and the integration of adsorption operations with the rest of the process. In this webinar, PSE will present how new tools for integrated design of periodic adsorption processes can help save time and money.

Design & Scale-up of Multitubular Reactors
Multitubular reactors are widely used for fixed-bed catalytic reactions, but good design and operation are challenging. A good design eliminates danger areas where hot spots can occur. This is achieved by adjusting reactor specifications to provide optimal heat control. Detailed modelling is the only reliable way to accurately predict heat transfer at all points throughout the reactor. This webinar describes a hybrid modelling approach, which simultaneously considers the fluid dynamics on the shell side and the catalytic reactions occurring in the tubes.

Integration of downstream unit operations in crystallization process design
In the first part of this work, we examine a continuous cooling crystallization cascade process and explore its optimization, while maintaining the content uniformity of the final solid oral dosage form. A number of optimization objectives are then posed, which include increasing throughput of the API and impact of continuous seeding. In the second portion, a model-based workflow for the scale-up of filtration is presented. The workflow begins with the estimation of the filtration properties from small scale pressure filter experiments. The cake properties were subsequently employed within a centrifuge model to predict the filtration behavior of the system at plant scale and to optimize the process schedule.

Precipitation of poorly soluble drugs: Experimental investigation using the Artificial Stomach Duodenum System and kinetics modelling using the gCOAS oral absorption model
In vivo drug precipitation has been a major issue facing poorly soluble drugs, especially weak bases. This work aims to provide a framework on how to use the Artificial Stomach Duodenum (ASD) System to assess the extent of precipitation of poorly soluble compounds under biorelevant conditions. The concentration profiles measured in the ASD System are used as inputs in the gCOAS® ASD model to estimate the nucleation and growth kinetic parameters. These crystallization kinetic parameters are then used in the gCOAS GI tract model to simulate in vivo precipitation under human fasted conditions and to calculate the fraction absorbed as a function of dose.

Biopharmaceutics risk assessment via gastrointestinal modelling
The biopharmaceutics performance of drug products can depend on multiple factors, including drug substance physicochemical properties, particle size distribution, patient physiology and dosage form composition. Even to the most experienced investigators, the interplay of these factors is not intuitive. In silico modelling allows for the low cost, rapid identification of risk factors affecting drug absorption. Formulators can then develop risk mitigation strategies before clinical trials, allowing them to design clinical studies to understand, confirm and mitigate the predicted risks.

Global System Analysis: Rapid and effective exploration of the process decision space
The main use of process simulation and modelling tools is to analyse "what-if" scenarios in order to improve process design and operation. Currently this is done manually as a point activity, using repeated simulation runs. Global system analysis (GSA) allows the comprehensive exploration of the behaviour of a system over domains of any user-selected subset of its input variables ('factors'), and output variables ('responses'). This provides a quick, easy and systematic way to explore the complex process design and operational decision space using high-fidelity models.
