Reactor Design

Because they represent the heart of a chemical plant — in which high-value products are produced through chemical transformation — reactors are a crucial component, and their high performance must be ensured. Reaction engineers are concerned with each reactor’s specific yield, selectivity, safety, environment, quality and purity — as well as the degree to which reactors support overall plant economic viability and optimal operational conditions.

Engineering simulation software from ANSYS is a powerful, reliable tool that complements conventional reactor engineering practices. By bringing comprehensive multiphysics capabilities to reaction engineering, ANSYS has created a simulation platform that encompasses fluid mechanics, structural mechanics, impact and safety analyses, customized mixing tools, pressure vessel analysis, electromagnetic and control systems, and heat and mass transfer analyses. ANSYS solutions can model a diverse range of reactions, including gaseous and liquid, single-phase and multiphase, and homogenous and heterogeneous.

ANSYS simulation tools enable reaction engineers to answer what-if questions as they design and enhance chemical reactors. Users can optimize reactor performance by better understanding the effects and impacts of feed locations, vessel geometries and internals, vibrations, failures, dead spots, shear rates, resident time distributions, hot spots, and particle size distributions.

ANSYS software helps a wide range of customers to simulate and improve a wide variety of reactors and reaction types.
