    Foaming could be a physical incorporation of a gas during a liquid. Foam is stable by solids, hydrocarbons, heat stable salts and different contaminants. method chemicals with wetter properties stabilise the froth too. Corrosion inhibitors, dispersants and emulsion breakers have wetter characteristics. Foam formation could cause health and questions of safety. Excessive foaming could result in pump cavitation, pump failure and loss of method management.

    The liquid film surrounds the gas making a bubble. The bubble wall or film could be a dynamic system, perpetually stretching and acquiring. once stretching is incorporates a high physical phenomenon. The dilutant film section contains less liquid. Immediate action is needed to stop or destabilise the froth. supported definition defoamer agents stop foam formation. Defoamers break existing foam.

    The liquid film surrounds the gas making a bubble. The bubble wall or film could be a dynamic system, perpetually stretching and acquiring. once stretching is incorporates a high physical phenomenon. The dilutant film section contains less liquid. Immediate action is needed to stop or destabilise the froth. supported definition defoamer agents stop foam formation. Defoamers break existing foam.

    Powerful defoamer agent additives ar meant to act with defoaming and defoamer agent properties. Antifoaming agent programmes increase the physical property of the shaped film layer. The defoamer agent provides a wetter diffusion. It creates a movie with a inbuilt weakness to become unstable. The defoaming agent properties destroy the froth formation straightaway and forestall a brand new formation of froth.

    Typical defoamer agenting agent applications are:

    Crude distillation tower and vacuum tower

    Delayed coker and visbreaker

    thermal cracker and hydrocarbon (asphalt) plants

    fill up oil extraction and fuel deasphalting

    Caustic scrubber, bitter water strippers and methane series units


    Delayed cokers and methane series units ar method units, wherever defoamer agent ar steady used. Foam carry-over from the coke drum should be avoided. Otherwise, that would ends up in Associate in Nursing sudden closure. PDMS based mostly defoamer agents ar primarily used at delayed cokers. they're the well-liked product due to the high thermal stability. an acceptable PDMS defoamer agent thermally decomposes, however the fragments still have defoamer agent properties. silicone polymer could be a catalyst poison, why the dosing should be done fastidiously.


    Foaming in methane series units is Associate in Nursing ubiquitous threat. The addition of liquid hydrocarbons to methane series solutions could be a primary cause for foaming. Foam carry-over within the absorbent material ought to be avoided. In methane series units, PDMS defoamer agents show superb foam management results. Polyol based mostly defoamer agents ar usually used likewise.


    Zilibon provides extremely economical defoamer agenting agent programmes. Defoaming agents straightaway displace the froth stabilizer and domestically burst bubbles. This reduces the wall consistence and lowers the electricity surface potential. Defoaming agent characteristics ar, that they're non-toxic and not harmful to product. with chemicals non-reactive properties ar needed. The defoamer agent ought to be straightforward to feed with non-volatile characteristics.

    Types of defoamer agent ar supported hydrocarbons, silicone polymer or chemical science. Organic defoamer agents ar polyols, fatty alcohols and esters. silicone polymer defoamer agent ar terribly economical defoamer agenting agent varieties. many sorts of silicone polymers ar offered like silicone fluids, emulsions, hydrophobised or substituted fluids.

    Zilibon defoaming agent formulations contain:

    Oil-free elements

    Natural oils or Mineral oils

    silicone polymer containing or silicone-free active substances

    Polydimethylsiloxane (PDMS)
