With ProMax, you can accurately model a variety of fractionation columns in refineries, including crude fractionators (atmospheric and vacuum), saturated gas plants, coker fractionators, and many others. Need to convert assay data into a mixture of compound and pure species? Our Oil Speciation Tool® allows you to do so with ease!

Crude Preheat Networks

With accurate thermodynamics, heat exchanger rating capabilities, and calculators for fine-tuning and optimization available in the software, you have the ability to properly model heat exchanger networks, track fouling, schedule maintenance, and improve energy integration.

AutoKinetic® Reactors

ProMax AutoKinetic® reactors provide you with a suite of rigorous reactor models to effectively simulate petroleum refining processes. These include hydrotreaters, hydrocrackers, catalytic reforming, and other hydro-processing systems.


With our powerful set of reactors, you have the ability to model a wide range of chemical reactions. You can choose from over 2100 pure components, supply rigorous kinetic rates, and model a variety of reactor types including plug flow, CSTR, and others.

Sulfur Recovery

With ProMax’s complete suite of reactor models, you can easily set up an accurate model of sulfur recovery unit operations. You are able to model real world behavior using a theoretical approach with empirical modifications based on decades of experience with these systems.

Acid Gas Removal

For over 40 years, BR&E has been known as the industry leader for simulating acid gas removal systems. ProMax continues this legacy and is the most versatile and complete package available for a variety of acid gas removal systems, all of which can be directly integrated with your other hydrocarbon processing systems in one simulation file!

Sour Water Stripping

Bryan Research & Engineering's custom electrolytic property package allows you to rigorously model any sour water stripper configuration, not only for NH3 and H2S, but for trace contaminants as well such as HCN and phenols. The robust electrolytic model easily accounts for pH and the addition of acids or bases to enhance stripping.
