Technical Information
1 of 2
The Dow Chemical Company has been at the forefront of gas treating technology for the
past 60 years, attaining a leading position in amines, UCARSOL™ solvents, and
specialized technologies, such as SELEXOL™ solvents and the UCARSEP™ amine
reclamation system. The development of new products, technologies, and services are part
of ongoing programs to provide for the current and future needs of the gas treating
industry.
One of the problems Dow has addressed is the foaming occasionally experienced in gastreating systems. These problems are usually the result of contaminants entering or
forming in the system. Improper operating conditions can also cause foaming. The best
cure is to find the cause and eliminate it. However, antifoams can be an effective interim,
or even long-term, cure if elimination of the cause is not possible.
Although antifoams have a wide range of applications in industry, many formulations are
not suitable for gas treating uses, and can actually aggravate the situation. Based on
extensive experience in commercial applications, Dow has developed a series of high-
performance antifoams specifically designed for gas treating uses. UCARSOL GT 10
antifoam, one of the specialized products in this series, provides foam control in amine
treating and glycol dehydration systems as well as in physical solvent applications.
UCARSOL GT 10 antifoam offers these important advantages:
• Provides foam control across a wider spectrum of contaminants
• Greater durability of foam resistance
• Improved foam control at low concentration
• Excellent mass transfer while controlling foam
• Ease of use
UCARSOL GT 10 antifoam is particularly useful in controlling foam conditions caused by
contamination from liquid hydrocarbons, particulates, or surfactants in general. Bothrefinery and natural gas processing facilities often encounter these types of contamination
and should consider the use of UCARSOL GT 10 antifoam in physical solvent
applications and in amine treating and glycol dehydration systems.
A versatile foam control agent, UCARSOL GT 10 antifoam provides these important
advantages:
• Excellent antifoam durability

• Effective for a broad spectrum of contaminants
• Reduced addition levels for control of severe foaming situations
• Improved product quality and stability for superior foam control
• Quick foam knockdown and rapid restoration of system performance
• Ease of use; easy to disperse with good dilute stability
• Improved overall performance of the system in terms of gas liquid separation and
reduced solvent loss
• Requires only low concentrations for effective foam control (generally 2-20 ppm)
To illustrate how the performance of UCARSOL GT 10 antifoam compares with other
antifoam products, a comparison test was performed using MDEA solvent under
controlled conditions (see Table 1 and Figures 1-4). The MDEA was placed in a 50/50
solution with water and solvent was then added. The solution was placed in a graduated
cylinder equipped with a glass frit sparge tube at a 1085 ml/ml gas rate for 5 minutes.

For answers to technical or support questions, contact your nearest Dow representative at
the numbers listed on the back of this brochure.
On-site plant assistance and quick responses are service benefits that come with the use of
UCARSOL GT-Series antifoams. An Engineering Consultant will provide technical
assistance as to the use level and application procedure.
Dow’s research and development laboratory facility has up-to-date equipment to provide
analytical and foam control troubleshooting capabilities for difficult-to-control systems.
UCARSOL GT 10 antifoam performance is dictated by the activity of the foamant and
system losses.
UCARSOL GT 10 antifoam can be added to the aqueous system before foaming occurs.
In the event of a foaming situation, UCARSOL GT 10 antifoam can be used at moderate
levels as a defoamer to quickly regain system control. It can be injected continuously or
batch-added. If a full-flow carbon filter is present, continuous addition is recommended.For slip stream or no carbon filtration, use either batch or continuous addition.
Generally, concentrations of 2 to 20 ppm UCARSOL GT 10 antifoam are adequate to
control foam in gas treating units. Typical concentrations are shown in Table 2 below.
However, we recommend that you contact Dow for specific recommendations or addition
amounts. With any foaming problem, an attempt should be made to identify and eliminate
the source of the foaming problem. Dow can provide assistance in identifying the cause.
