Reacting Flows

Steam Methane Reformer for Syngas

Adding heat and steam to methane (CH4) results in syngas: a mixture of carbon monoxide (CO) and hydrogen (H2). This process can be used to create hydrogen for use in fuel cells. Alternatively, the syngas can be used as feedstock for the production of liquid fuels using the Fischer-Tropsch or Mobil processes. These pathways are important for development of biofuels (ethanol and bio-diesel from biomass) and other fuels and fuel oils as part of coal-to-liquid (CTL) and natural gas to liquid (GTL) refining.

SINDA/FLUINT (via Thermal Desktop® with FloCAD®) offers important functionality for the design and simulation of such systems, including:

  • Equilibrium reactions, finite-rate kinetics (“reacting flows”), or both within one system
  • Detailed analysis of heat transfer and heat exchange equipment for concurrent design of realistic reformer geometries
  • Inclusion of the entire process (e.g., steam generation)
  • Ability to resolve fast time scales for stability investigations and evaluations of control strategies
  • Orders of magnitude faster solutions than CFD, enabling sizing and sensitivity studies

A set of thermohydraulic models is available that focus on a plug-flow reactor (PFR) arrangement for a simplified methane steam reformer. The models are available in FloCAD format, and include:

  • Validation against other tools and methods
  • Demonstration of finite-rate kinetics (reacting flows) using Arrhenius-type coefficients
  • Demonstration of equilibrium chemistry co-solved with thermal/fluid equations
  • Demonstration of steady-state and fast transient solutions (e.g., control time scales)
  • Use of chemical equilibrium software for generation of fluid properties, including “equilibrium fluids”
  • Discussion of methods for including coke (carbon) formation

FloCAD online training

Class times: May 2 & 4 from 10am to 2pm MT

Cost: $425

This online class will provide an introduction to fluid modeling components within FloCAD. The class will be held over a 2-day period, with daily sessions running approximately 4 hours each. The class uses a mixture of lecture, demonstrations, and self-paced tutorials to allow attendees to practice building fluid system models and interpreting results. The presentations will comprise 2 - 3 hours of each session, and the instructor will be available during the remainder of the time for questions during tutorials. Attendees must have basic working knowledge of SINDA and Thermal Desktop as these topics will not be covered but their usage is required for FloCAD.

Using Sinaps? It is not too soon to get started with TD/FloCAD!

This webinar describes the process for converting from Sinaps to Thermal Desktop (TD) and FloCAD. This process includes using an exporter which works with Version 6.0 of the CRTech tool suite (expected to be released in May of 2017).

Come learn about the basics of TD/FloCAD, including many compelling features not available in Sinaps. The webinar will also cover how to manage the transition period, during which you may be using both programs simultaneously. This is also a chance to ask questions.
