Overview of Osorb® Media Technology – Results from Trials and Gas Deliquification Applications

February 2014

Gregory Scott Hallahan Product Development Manager g.hallahan@pwasystems.com

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
