Environmental awareness is leading to the development of greener defoamer chemistries that have minimal impact upon the environment but still perform as expected in providing high efficiency and persistency during the extraction process. The industrial area covers scrubbing, dehydration, separation, deliquefaction, and drilling in the gas, oil, and coal industries. The extraction of oil and gas requires the separation/purification of the hydrocarbon from water as an emulsion. The emulsion is extremely foamy, so to provide optimal running efficiency in the separator or dehydration units, the AGITAN® or FOAM BAN® products can be used in an environmentally responsible manner.
