Instead of conventional system:
- Higher mass transfer rate
- Smaller, modular system design
- Higher equilibrium efficiency for each stage (Murphee efficiency 90-95%)
- Reduced solvent usage
- Fewer extraction stages to achieve desired extraction
- Specialized Pentair Media to minimize solvent carry-over (removal of sub-micron size droplets)
- High turndown ratio
- Reduced CAPEX and OPEX
- Fewer operational issues (i.e. flooding, etc.)
Conventional Systems
Trayed Columns & Packed Columns are conventional approaches to remove dissolved contaminants that utilize washing the hydrocarbon with water.
Disadvantages
- High solvent losses
- Low operating window
- Low stage efficiencies
- Bigger equipment size
- Higher solvent re-circulation rates
- Higher capital cost
- Poor separations of process and solvent streams
- Caustic recovery
- Amine recovery from Liquefied petroleum gas (LPG)
- Amine treating Natural Gas Liquids (NGL)
- Methanol removal
- Chloride salt removal from Butane
