Caustic Systems

Leveraging four decades of electrolytic modeling experience, ProMax® provides extremely accurate and easy-to-use capabilities for fast, robust caustic system modeling. Almost any configuration or system can be modeled, including acid gas removal from ethylene washes, mercaptans removal from hydrocarbon liquids, selective SO 2 scrubbing, and more!

Regenerative Caustic Systems for Mercaptans Removal

Calculate Mercaptans Absorption from vapor-liquid or liquid-liquid columns

Perform Oxidative or Thermal Regeneration of the Rich Caustic
Have confidence in advanced thermodynamics for accurate distribution of mercaptans, disulfide oils, and water in three-phase systems
Scrub regenerated caustic with hydrocarbon liquid for further disulfide oil removal
Determine minimum air flow requirements to oxidative regenerator
Calculate spent caustic rates due to H 2 S and CO 2 ingress into the system

Caustic Scrubbing of Ethylene

Mass+Heat Transfer Model for High Accuracy
Easily set pumparound loops for multi-stage designs
Ionic Info Analysis provides simple tracking of spent vs. free caustic in the solvent loops
Integrated water wash loop for clean model appearance
Optimize pumparound rates and caustic addition/removal to minimize costs
Determine correct number of trays required to meet tight product specification

Selective SO 2 Scrubbing from Flue Gas

Mass+Heat Transfer Model for High Accuracy
Easily set pumparound loop for balanced L/G
Ionic Info Analysis provides simple tracking of spent vs. free caustic in the solvent loop
Optimize pumparound rate and caustic addition/removal to minimize costs
Determine correct number of trays required to meet desired SO2 selectivity
Estimate cost of flue gas scrubbing to meet MARPOL requirements on use of high sulfur bunker fuel
