2/3 PHASE SEPARATOR

AI Energy Solutions can provide two-phase (gas/liquid) or three-phase

(gas/oil/water) separators depending

on the client’s particular needs.

Generally separator sizing is based on

gas quality performance, neither ad-

dressing oil nor water quality.

FREE WATER

KNOCKOUTS (FWKO’S)

AI Energy Solutions FWKO designs are based on empirical data developed over

50 years of practical experience. AI

Energy Solutions provides two-phase

(oil/water) and three-phase (oil/gas/

water) FWKO designs.

The primary focus of a FWKO is to re-

move free water from the production

inlet stream.

DESALTER

The presence of salt in the crude oil

poses a risk to downstream oil pro-

cesses. High salt content causes in-

creased corrosion, increased fouling of

equipment, and will hinder certain

chemical & physical reactions.

AI Energy Solutions can provider 1st

stage to 3rd stage desalters to suit the

clients requirements.

Crude Oil & Condensate Treating & Stabilization

Stabilizer Systems

With the high value of hydrocarbon liquids makes it essential that you

install reliable, high-performing systems for treating the liquids, max-

imizing recovery, and transporting and storing them safely.

FEATURES

Outlet gas ambient heat exchang-

er

STABILIZERS

Stabilizer plants are used to reduce the

volatility of stored crude oil and con-

densate. These novel process units also

maximize recovery of hydrocarbon

liquids that might otherwise be lost to

the natural gas stream. AI Energy Solu-

tions designs are field-proven to be

reliable and easy to operate, ensuring

maximum liquid recovery.

C5 RECOVERY PLANTS

AI Energy Solutions C5 recovery plants

are optional extensions of the AIES

stabilizer plant, and often provide in-

creased recovery of natural gas liq-

uids.

Gas Dewpointing

Joule—Thompson

Natural gas contains a wide range of hydrocarbon compounds, some of

which can condense and form liquids that can cause problems with

pipelines and downstream equipment. Refrigerating the gas lowers the

hydrocarbon dewpoint, thereby condensing and removing these hydro-

carbon liquids.

JT VALVE

JT plants use the Joule-Thompson ef-

fect to cool natural gas by expanding it

across a pressure-reducing valve. The

expanded gas cools rapidly, causing gas

liquids to condense for separation in a

gravity separator.

HOW IT WORKS

High-pressure gas enters through the

gas/gas exchanger and chiller for pre-

cooling. Methanol is injected to help

prevent formation of hydrates, and the

raw natural gas passes through a JT

valve. The resulting Joule-Thomson

effect causes a pressure drop that expands the gas and significantly re-

duces temperature. The cooled gas is

routed to the cold separator, which

removes condensed NGL. Outlet gas

from the cold separator is routed

through the gas/gas exchanger for0 inlet cooling. The NGL from the cold

separator is routed through the inlet

NGL/gas exchanger and then to a pres-

surized NGL storage tank.

Gas Sweetening

Produced natural gas often contains too much carbon dioxide (CO2) and

hydrogen sulfide (H2S) gasses to allow safe production and sale.

AI Energy Solutions offer advanced amine and scavenger plants to re-

move CO2 and H2S from natural gas production at the wellhead.

AMINE PLANTS

AI Energy Solutions Amine System re-

moves contaminants such as carbon

dioxide and hydrogen sulfide from natu-

ral gas streams in order to meet pipe-

line or pretreatment specifications.

With expertise in engineering state-of-

the-art plant designs and bringing them

online quickly. So you can see produc-

tion profits faster.

SCAVENGER PLANTS

AI Energy Solution scavenger plants are

also modular and self-contained, and

are used to remove up to 2,000 ppm of

H2S from natural gas using chemical

scavengers.

The scavenger plant maximizes the

efficient use of the chemical, and the

resulting spent chemical is safe for

disposal with produced water.

Gas Dehydration

TEG Dehydration Package

Natural gas contains water vapor that cannot be removed with separa-

tors or filters. This water vapor can condense and turn to liquid water,

which can corrode or block downstream pipelines and equipment.

HOW IT WORKS

Wet gas enters the bottom of the

absorber tower. As the gas rises

through the tower’s packing or bub-

ble cap trays, water is absorbed by

descending lean glycol (water re-

moved through regeneration pro-

cess),. Drier gas exits the top of the

tower and passes through the gly-

col/gas heat exchanger to the gas

outlet. The rich glycol collects in the

hat tray at the bottom of the tower

and flows to the power side of the

glycol pump. From the pump, the rich

glycol flows through a reflux coil,

heat exchanger and flash gas sepa-

rator, which divides gas and en-

trained hydrocarbons from the gly-

col. The gas then flows to the fuel gas

scrubber and the lean glycol flows

through a filter into the reboiler. The

hot, reconcentrated glycol flows

from the reboiler to the sparger box

to remove additional water vapor.

The lean glycol flows to the storage

compartment and then to the heat

exchanger for cooling. The cooled,

lean glycol then flows through a gly-col sock filter before passing to the

glycol pump. Lean glycol and gas

from the absorber together power

the glycol pump, which pumps the

glycol through a glycol/gas heat

exchanger to minimize glycol loss

and then to the absorber tower to

continue the dehydration process

cycle.

GLYCOL REGENERATORS

Glycol regenerators: Regenerators are

used to reconcentrate or regenerate TEG by heating and driving off absorbed

water so that the TEG can be reused for

natural gas dehydration. AI Energy So-

lutions offers standard designs with

heat rates ranging from 125,000 btu/

hr.

ABSORBERS

AI Energy Solutions offers a wide range

of absorbers (contactors) that are

used to contact natural gas with TEG to

remove water vapor from the gas.
