BRE 235: Physical Solvents


The Physical Solvents course is a detailed discussion of gas sweetening units that utilize physical solvents and hot potassium carbonate. The operating principles of these units are presented and modeled in ProMax®, as well an exploration of the rationale for common variations seen in these process units.

In this one (1) day course ProMax users are given opportunities to explore and gain understanding of physical solvent and hot potassium carbonate systems through extensive, hands-on use of the Scenario Tool® and ProMax models. The course demonstrates how to use these tools for plant design and process optimization.

Attendees will learn:

  • Specific applications of ProMax and its features with regards to physical solvent and hot potassium carbonate processes
  • Capabilities and features of ProMax simulation software
  • Plant modeling techniques and methods


  • Any 100 level course or equivalent experience
  • Understanding of ProMax specifiers, solvers, and Scenario Tool


  • Instructor-led demonstrations
  • Hands-on simulation
  • Question-Answer
  • Open floor discussion


Installation of ProMax

The first step in all courses is to verify that ProMax is properly installed on each attendee’s computer.

Section 1: Physical Solvents
  • Exercise 1: Basic DEPG Facility – Demonstrates specifying a model containing the basic unit operations found in a physical solvent facility. Begins with a simple model and gradually adds unit operations to showcase their purpose. Reviews various simulation tools like short monikers, solvers, specifiers, and user value sets. Ends with how to use Mass + Heat Transfer columns.
  • Exercise 2: Solvent Circulation Rate – Utilizes the Scenario Tool to perform a case study on how the high pressure (HP) separator pressure and lean solvent temperature impact utility consumption, column size, and solvent flow rate in a DEPG facility. Additionally, introduces the concepts of lean and rich approach and how they can be used to determine facility performance.
  • Exercise 3: Propylene Carbonate (PC) vs. DEPG – Compares the performance of PC to DEPG for both CO2 and H2S absorption.
  • Exercise 4: Advanced DEPG Absorption – Demonstrates how thermal regeneration is modeled in ProMax and compares the two-absorber DEPG system to the single-absorber system.
Section 2: Hot Potassium Carbonate
  • Exercise 5: Hot Potassium Carbonate – Introduces the concept of chemical absorption by explaining the hot potassium carbonate facility. Also demonstrates how to use the salt example stencil and the splitter/mixer configuration for makeup/blowdown. Ends by demonstrating the UOP Benfield™ HiPure process, which utilizes hot potassium carbonate and alkanolamines to treat sour gas.
