Foam
is a problem.
Silicone foam control is the solution.
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 for the Oil and Gas
Industry
Below are short descriptions of a few applications where silicone antifoams
are commonly used today.
Gas-Oil Separation – Certain crudes tend to foam while undergoing
depressurization to release entrapped gas. This tendency can severely 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.
There are many different options of Dow Corning® Silicone
Antifoams that can be used in gas/oil separators. Most of these neat antifoams
are of quite high viscosity and can be supplied as a concentrate for ease of
handling. We can customize a blend of selected silicone based fluids and
solvents to meet your needs, exactly. Save costs and time by choosing the right
blend.
Gas Scrubbing – Gas scrubbers used to remove CO2 and
H2S from gases are prone to foam. Such processes are commonly used
for natural gas, 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, well-head 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, as well as
loss of expensive absorbent by carry-over. The foam can be controlled by
feeding Dow Corning® silicone antifoam into the absorber/contactor
and regenerator columns.
