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 special foaming problems occur. TERRAFOAM® line antifoam agents help maintain maximum separator capacity and well output. 
Drilling mud
These vital fluids are extremely surface active and prone to foam. Special-purpose TERRAFOAM® line foam control systems effectively suppress that foam. 
Gas dehydration
Stripping water from glycols such as di-, tri- or tetraethylene glycol during drying of gas often causes severe foaming. This leads to high glycol loss and reduction of throughput. TERRAFOAM® line anti-foaming agents added to the make-up glycol stream usually eliminate the problem.
Gas scrubbing 
Gas scrubbers used to removed 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 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 reduced throughput as well as loss of expensive absorbent by carry-over. The foam can be prevented by feeding a silicone antifoam into the absorbent stream or into the top of the absorber. TERRAFOAM® line antifoams are ideal to answer this need.
