Typical Amine System
Before entering the absorber, the gas is
passed through an inlet separator where
entrained droplets or slugs of liquid are
removed from the gas stream by
impaction devices (to the right >>>>>)
Inlet Gas Knockout
Baffles remove a portion of the liquids. Mist eliminator pads, located
near the gas outlet of the tank, trap the rest. Typical contaminants in
natural gas streams may be liquid hydrocarbons, salt water, sands, well
treating compounds, pipeline treating chemicals, and compressor oils.
18. WWW.GBHENTERPRISES.COM
Typical Amine System
The sour gas, freed of entrained
liquids by the inlet separator, enters
the bottom of the absorber. Usually
the absorber is a tray column;
although packed columns are also
used. In either case, the objective is
to provide intimate contact between
the gas and the amine solvent so that
the H2S and C02 molecules can
transfer from the gas phase to the
solvent liquid phase. In tray columns,
a liquid level is maintained on each
tray by a weir usually 2 or 3 inches
high (Figure >>>>>).
Tray Tower Absorber
19. WWW.GBHENTERPRISES.COM
Typical Amine System
Three Phase Flash Tank
In many units the rich amine solution is
sent from the absorber to a flash
skimmer tank to recover hydrocarbons
that may have dissolved or condensed
in the amine solution in the absorber.
The pressure of the solution is dropped
as it enters the tank, allowing the
lightest of the hydrocarbons to flash.
The heavier hydrocarbons remain as a
liquid, but separate from the aqueous
amine, forming a separate liquid layer.
20. WWW.GBHENTERPRISES.COM
Typical Amine System
Lean/Rich Heat Exchanger
The rich solvent is preheated before entering
the stripper. Because the lean amine exiting the
reboiler must be cooled before entering the
absorber, there is an opportunity to exchange
heat from the lean to the rich stream, thereby
reducing the heat load on the reboiler.
This is usually done in a shell and tube
lean/rich heat exchanger with the rich solvent
passed through the tubes, which are usually
made of stainless steel.
Note: Recommended maximum velocity to minimize corrosion
in the tubes is 3 or 3.5 feet/sec.
21. WWW.GBHENTERPRISES.COM
Typical Amine System
Regenerator
Like the absorber, the stripper is either
a tray or packed column with
approximately 20 trays or the equivalent
height in packing. To minimize amine
vaporization loss, there may be a water
wash section at the top of the column
with an additional four to six trays.
The preheated rich amine enters near
the top of the column and flows down
countercurrent to a gas stream of
steam, H2S, and C02. The steam is
generated in the reboiler, lowering the
partial pressure of H2S and C02 in the
gas stream, enhancing driving force of
the acid gases from the amine solution.
22. WWW.GBHENTERPRISES.COM
Typical Amine System
Filtration
A filtration scheme of mechanical and
activated carbon filters is important in
maintaining good solution control.
Mechanical filters such as, cartridge
filters or precoat filters remove
particulate material while call filters
remove chemical contaminants such
as entrained hydrocarbons and
surface-active compounds.
Filters are located in the rich line in some plants, and in the line in
others. One manufacturer recommends filters in both rich and lean
lines. Locating the filters in the rich line upstream of the lean rich
heat exchanger will protect both the heat exchanger and the
stripper from plugging, and reduce the erosion/corrosion rate in
the heat exchanger.
23. WWW.GBHENTERPRISES.COM
Typical Amine System
Filtration
A 10 to 20 micron mechanical filter
should be adequate for particulate
removal. If cotton filters are used, the
cotton should be virgin cot ton rather
than recycled. Recycled cottons
may contain fibers with coatings which
may be the source of amine solution
foaming problems.
Circulation rates through mechanical filters range from 5% of the
circulating system to full fl depending on the degree of contamination.
Recommendations for flow to carbon filters range from less than I
percent to 5 to 10 percent and some units have been built with full flow.
24. WWW.GBHENTERPRISES.COM
Criteria In determining when a carbon bed should be changed
The following can be used as a guide:
1) a high pressure drop across the bed, caused by solids plugging
the voids;
2) a color comparison between a sample taken from the outlet
of the filter and a plant sample run through fresh carbon in the lab.
Active carbon will remove color;
3) an increase in foaming tendency in the plant, or the start of
a foaming problem.

Operating Difficulties
Amine gas sweetening plants can experience operating
difficulties including foaming, failure to meet sweet gas
specification, high solvent losses, corrosion, fouling of
equipment, and contamination of the amine solution.
Often one operating difficulty is the cause of another.
Not all plants experience the same problems to the same degree,
and what may be a continual problem in one plant may occur
only rarely in another.
Typical Amine System
31. WWW.GBHENTERPRISES.COM
Operating Difficulties: Foaming I
Typical Amine System
Pure aqueous amine solutions do not foam. It is only in the presence of
contaminants such as condensed hydrocarbons, small suspended
particulate matter, or other surface active agents such as some pipeline
corrosion inhibitors or compressor oils, that a foaming problem may
develop.
Foaming usually occurs in the absorber or the stripping tower, and is
accompanied by a sudden noticeable increase in the differential
pressure across the column.
Other indications of a foaming condition may be a high solvent
carryover, a drop in liquid levels, and the detection of off-specification
gas.
32. WWW.GBHENTERPRISES.COM
Operating Difficulties: Foaming II
Typical Amine System
An immediate method to control a foaming problem is the addition of
an antifoam at a location just upstream of the foam.
Effective foam inhibitors for amine sweetening systems are silicone
antifoams and polyalkylene glycols. Also widely used are high-boiling
alcohols such as oleyl aIcohol and octylphenoxyethanol.
It is advisable to test the antifoam on a plant sample in the laboratory
before applying it in the field to verify that it will break the foam.
In the event that one antifoam is ineffective, switching to another
antifoam may solve the problem.
33. WWW.GBHENTERPRISES.COM
Operating Difficulties: Foaming III
Typical Amine System
The silicone antifoams have proven to be quick and effective in
controlling foaming problems in the gas treating industry. When using
a silicone antifoam, the antifoam should be added downstream of the
carbon filters because carbon filters will adsorb the silicone.
Care should be exercised with respect to the amount of silicone
antifoam added to a system.
The silicone antifoams should be used only in small quantities, as
recommended by the manufacturer.
It is important to be aware that silicone antifoams used in excessive
quantities have the potential to promote the formation of foam.
34. WWW.GBHENTERPRISES.COM
Operating Difficulties: Foaming IV
Typical Amine System
The use of an antifoam may only be a temporary solution to a
continuing problem. The objective in controlling foaming should be to
minimize the level of contaminants in the amine solution.
Of critical importance is the prevention of entrained contaminants in
the feed gas from entering the amine system.
The inlet separator, equipped with a demister pad and possibly filters,
is instrumental in trapping most contaminants, and should be
monitored to insure that it is operating efficiently and not being
overloaded.
Mechanical and carbon filters are necessary in maintaining a clean
solution. In order to prevent hydrocarbons from condensing in the
absorber, the lean amine feed temperature should be held between 10'F
and 20'F above the temperature of the feed gas.
37. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification I
Difficulty in meeting the sweet gas specification may be the result of
poor contact between the gas and the amine solvent, which may in turn
be caused by foaming or mechanical problems in the contacting
equipment.
In the case of foaming, the gas remains trapped in bubbles, unable to
contact the rest of the solvent, resulting in poor mass transfer of acid
gas from the gas to the amine solution.
In terms of mechanical damage, if trays are broken or have fallen, there
may not be enough contact zones (trays) for adequate sweetening. If the
trays are plugged, there is less contact between the gas and liquid on
each tray, resulting in poorer sweetening.
38. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification II
Other explanations for off-specification gas may be related to the amine
solution:
The circulation rate may be too low,
The amine concentration too low,
The lean solution temperature may be too high,
The acid gas loading in the lean solution may be too high.
Monoethanolamine systems usually run with solution concentrations
between 10 and 20 weight percent MEA, and a lean loading of 0.1 moles
acid gas/mole of MEA.
39. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification III
Diethanolamine systems are between 20 and 30 weight percent DEA,
with lean loadings of 0.02 to 0.05 moles acid gas/mole DEA.
In order to reach these lean loadings, regeneration resulting in a steam-
to-acid gas ratio ranging from 1:1 to 3:1 (moles steam: moles acid gas)
in the stripper overhead gas is usually required (1). In some cases, even
higher ratios may be necessary to bring the loading down, as in low-
pressure treating applications.
40. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification IV
One way to estimate the overhead steam-to-acid gas ratio, knowing the
stripper overhead temperature and pressure, is to use steam table data
and Raoult's law:
PP H2O = x H2O psat
where: PP H2O = partial pressure of water in the overhead gas;
X H2O = mole fraction of water in the amine solvent;
psat = vapor pressure of pure water at the temperature
of the overhead gas.
41. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification V
Approximating the overhead gas as an ideal gas containing water, H2S
and C02, the partial pressure of the acid gases can be obtained by
subtracting the partial pressure of water, calculated from Raoult's law,
from the stripper overhead pressure:
PPacid gas = Poverhead – PP H2O
The ratio of water partial pressure to acid gas partial pressure is equal to
the mole ratio of steam to acid gas.
42. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Failure to Meet Gas Specification VI
As an example calculation of the steam-to-acid gas ratio, a stripper with
an overhead temperature and pressure of 200'F and 20 psia, carrying a
27 weight percent (6 mole percent) DEA solvent, has a corresponding
water vapor pressure of 11.5 psia as obtained from the steam tables.
From Raoult's law, the partial pressure of water is 10.8 psia:
PPH2 0 = (0.94) (11.5) = 10.8 psia
The partial pressure of acid gas would be 20 psia less 10.3 psia or 9.19
psia, and the overhead steam-to-acid gas ratio would be 1.2 moles
steam/mole acid gas (10.8 -t 9.19).
44. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Solvent Losses
Amine losses are largely through entrainment, caused by
foaming or excessive gas velocities, and by leakage due to
spills or corrosion. In MEA units the reclaimer bottoms
disposal significantly adds to the makeup requirement.
On a much smaller scale are vaporization losses from the
absorber, the overhead condenser, and the flash tank, and
degradation losses by chemical and thermal degradation
47. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Corrosion I
Corrosion is a problem experienced by many alkanolamine gas
sweetening plants.
When loaded with C02 and H2S, aqueous amine solutions can
become corrosive to carbon steel.
Corrosion rates are increased by high amine concentration, high
acid gas loading, high temperatures, degradation products, and
foaming.
Also corrosive are acid gases flashed from solution.
48. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Corrosion II
Monoethanolamine is more reactive than diethanolamine and similarly more
corrosive. As a result, the concentration of MEA is restricted to 10 to 20
weight percent, while DEA strengths range from 20 to 30 weight percent.
Rich solution loadings are normally limited to the range of 0.25 to 0.45
moles acid gas/mole MEA, while in DEA systems loadings may range from
0.5 to 0.6 moles acid gas/mole DEA.
The corrosiveness of a loaded amine solution is strongly influenced by the
relative proportion Of C02 to H2S in the feed gas. C02 is more corrosive to
carbon steel than is H2S in aqueous systems.
49. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Corrosion III
Thus, for gases containing a higher ratio Of C02 to H2S, the rich
acid gas loading should be maintained at the lower end of the
recommended loading range.
In cases where the feed gas is predominantly H2S, loadings at
the higher end of the loading range may be acceptable.
In terms of design, a number of measures can be taken to
minimize corrosion. Solution velocities should not exceed 3 or
3.5 ft/sec.
50. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Corrosion IV
The rich solution should be on the tube side of the lean/rich heat
exchanger, and pressure should be maintained on the exchanger to
prevent acid gases from flashing, creating an erosion/corrosion cycle.
A low temperature heating medium should be used in the reboiler,
thereby preventing accelerated corrosion rates and thermal degradation
of the amine.
All equipment should be stress relieved.
51. WWW.GBHENTERPRISES.COM
Operating Difficulties
Typical Amine System
Corrosion V
There are certain areas of amine sweetening plants which are more
susceptible to corrosion than others, and, as a result, are often
constructed of corrosion-resistant materials such as Type 304 stainless
steel.
These areas include:
1) the lean/rich heat exchanger tube bundle,
2) the reboiler tube bundle,
3) the stripping column, particularly the upper section and
overhead gas line,
4) the reflux condenser, and
5) the rich solvent let-down valve and subsequent piping to the
stripper.
