Advanced : Advanced Reactor Design for CSTR (1-day)

Generally, a successful small-scale (lab or pilot) reactor cannot be directly scaled-up to a large commercial-scale reactor due to different hydrodynamic characteristics between the two scales. Modelling techniques combined with experiments are very effective upon the scale-up design of a commercial-scale reactor in terms of reducing time, effort, and cost. For this purpose, modelling techniques should be able to effectively capture 3D hydrodynamics happening inside a commercial-scale reactor together with non-flow phenomena.

SPSE’s hybrid gPROMS-CFD modelling technologies engage CFD to reactor modelling in a cost-efficient way. "Non-flow" phenomena (reaction, multicomponent mass transfer, etc.) from gPROMS and "flow" phenomena (mixing, turbulence, etc.) from CFD are considered simultaneously using hybrid gPROMS-CFD interfaces. These interfaces make it possible to solve complex reaction systems in a reasonable time but can capture the right level of detail of physics necessary for predicting reactor performance. As a result, engineers can do a successful scale-up from small-scale to comer-scale with reduced time, cost, and risk.

There are various products in SPSE’s hybrid gPROMS-CFD modelling interfaces. This course covers the “hybrid gPROMS-CFD Multizonal interface” developed for the detailed modelling of general-purpose reactors. This interface is suitable to capture both non-flow phenomena and flow phenomena in crystallizers, polymerization reactors, and gas-liquid reactors.


This course is aimed at chemical and process engineers who wish to develop a commercial-scale reactor using hybrid gPROMS/CFD modelling technology with the minimum experiments (to identify reaction kinetics) done in the lab-scale or pilot-scale reactor.


This one-day course helps attendees to apply effectively advanced reactor design techniques to the design or scale-up of chemical CSTRs (continuously stirred tank reactors). It combines tutorials and hands-on sessions. By the end of this course, attendees will:

  • Understand why considering non-ideal mixing is important upon the scale-up design of a commercial-scale reactor from a small-scale (lab or pilot) reactor
  • Understand the concept and usage of hybrid gPROMS-CFD Multizonal simulation
  • Know how to set up optimization problems to find the best operating condition of the reactor
  • Know how to export hybrid Multizonal simulation results from gPROMS to CFD


The course assumes that attendees have both knowledge of gPROMS to the level covered by the courses "Introduction: gPROMS Process" and "Advanced: Custom Modelling and Model Publishing," and usage experience of commercial CFD software, ANSYS Fluent.
