Applied to:
• Produced Water
• Flowback &
Completion Returns
• Pipeline Fluids
• Membrane Protection
• Chemical EOR
Removal of free,
dispersed,
emulsified,
and soluble
hydrocarbons and
many oilfield
chemicals from
water.
Osorb® Media:
• Organically-Modified Silica
• Porous, Flexible Matrix
• Hydrophobic
• Adsorption & Absorption
• Regenerable & Reusable
Application Methods:
• Bulk Media Vessel
• Injection into Flow Line
Osorb® Media Technology
Lower Molecular Weight Sorbates
1. Gaseous / steam purge to volatilize sorbates from Osorb
Higher Molecular Weight Sorbates
1. Displacement fluid purge to displace high molecular weight sorbates with lower molecular weight displacement fluid
2. Gaseous purge or steam purge to volatilize displacement fluid from Osorb
Other General Mechanisms of Desorption • Pressure Swing • Concentration Reduction • Chemical Changes • Mechanical Force
