Breakthrough Analyzer for Studying Single- and Multicomponent Gas Adsorption

The dynaSorb BT® series provides exceptional capabilities to investigate complex dynamic gas adsorption processes in a uniquely safe and easy-to-use bench-top instrument. Industrial adsorbents used in gas separation and gas purification applications, such as zeolites, active carbons, silica gels, etc., can be investigated under real process conditions within broad temperature (-20 °C to 400 °C) and pressure (up to 10 bar) ranges, using adjustable gas flow rates (up to 40 L/min) of well-defined multicomponent gas mixtures employing a fixed bed breakthrough analyzer capable of measuring competitive gas adsorption.

Dynamic Gas Sorption Capabilities

The gas mixing and analysis features of the dynaSorb BT® make it ideal for determining a wide range of adsorption and absorption characteristics such as:

  • Gas separation effectiveness
  • Gas purification efficiency
  • Breakthrough analysis
  • Determination of sorption selectivity
  • Competitive adsorption behavior
  • Multicomponent adsorption isotherms
  • Water and organic vapor sorption
  • Dynamic gas adsorption kinetics
  • Maximum absorber regeneration cycles
  • Demo mode for operator training and education
  • Historical data trending
  • User account management (hierarchy of user levels)
  • Definition of analysis conditions and intelligent start/stop criteria
  • Configuration of complex analysis sequences
  • Fully automated execution of analysis sequences
  • Well-structured data files to capture the experimental conditions and analysis data
  • Auto save function to protect data integrity
The status of all sensors and valves, the path and direction of gas flow, and all relevant system information for safe and convenient operation can be viewed at a glance on the controlling PC.

The data reduction and simulation software dynaSim provides sophisticated results calculation and modelling of competitive adsorption data, including:

  • Integration of breakthrough curves
  • Simulation and prediction of breakthrough behavior and heat profiles
  • Parametric studies of gas separation and gas purification processes
  • Calculation of single- and multicomponent adsorption data
  • Prediction of mixture equilibria using a variety of theories (IAST with Langmuir, IAST with Toth, Multicomponent Langmuir, Multicomponent Sips)
  • Determination of selectivity, affinity, and mass transfer coefficients
  • Fitting isotherms to mathematical models (Henry, Langmuir, Toth, Sips, Freundlich)
Ideally suited for both in-depth technical calculations and basic research, dynaSim™ accommodates it all, making it a powerful tool for both industry and academia.
