Knock out foam with silicone
solutions for optimized process performance
From the wellhead through refining, processing and even shipment of the
finished product, foam can cause major problems in the production and refining
of oil. Silicone foam control agents from Dow Corning eliminate process
foam in production, refinery and gas-processing plants. Eliminating process
foam can increase your productivity, reduce your production costs and,
consequently, save you money.
Silicone foam control expertise
for the oil and gas industry
Count on Dow Corning for the expertise you need to provide solutions to
your foam control challenges, in applications including:
Gas-oil separation – Certain crudes tend to foam while undergoing
depressurization to release entrapped gas. This tendency can substantially
limit output and is especially severe on offshore rigs where vessel size is
limited and special foaming problems can occur. Using as little as 1 to 5 parts
per million silicone antifoam from Dow Corning can help you maintain
maximum separator capacity and well output.

Many Dow Corning® brand silicone antifoams are available for use
in gas/oil separators - save costs and time by choosing the right blend. Select from high-viscosity neat
antifoams that can be supplied as a concentrate for ease of handling - or let
us customize a blend of
selected silicone-based fluids and solvents to meet your specific needs.
Gas scrubbing – Gas scrubbers used to remove CO2 and H2S from gases
are prone to foam. Such processes are commonly used for natural gas and
refinery gas, in gas treatment as a part of reforming, in ethylene production
(steam cracking), and in the production of ethylene oxide. Trace impurities
such as liquid hydrocarbons, wellhead inhibitors, corrosion solids and valve
greases in the incoming gas can cause foam regardless of which absorbent (MDEA,
DEA, TEA and DGA or carbonate solution) is used.
Foaming can cause poor separation efficiency, reduced throughput and loss of
expensive absorbent by carry-over. Control harmful foam by feeding
Dow Corning® silicone antifoam into the absorber/contactor and
Product recommendations for gas scrubbing:
Delayed cokers – Foam typically occurs during the process of coking
heavy oil and asphalt fractions. The addition of 10 ppm of a silicone antifoam
dispersed in kerosene, either directly to the drum or before the furnace,
generally controls the foam. Increased drum runs and reduced coke deposits in
overhead vapor lines can be realized.
