Gas Deliquification Conference 2013Mike Smith – Managing Director, PWA Europe

14 – 16th October

Who We Are

Incorporated: 2011

Venture capital funding:

• Energy Ventures

• Harris & Harris Group

Osorb® Media - a

regenerable media which

removes, free, dispersed &

soluble hydrocarbons &

toxic contaminants from

oilfield water & gas streams.

PWA is to be the

internationally recognized

produced water treatment

solution provider of choice

within the oil and gas

industry.

The primary market for

Osorb is the treatment of

produced water to meet

discharge and reinjection

specifications.

Hydrocarbon Dew

Point Reduction

(HDPR) in natural gas

at client well site.

Capture of the liquid

and vapor-phase

heavier hydrocarbons in

the gas stream

HDP reduced from

58°F to -92°F @ 80 psi

and 80°F

Regeneration of

Osorb with heat and
