Highly effective liquid antifoam formulated for controlling foaming and priming in seawater distillation plants compatible with most antiscalants

Product Description: 

Antifoam Defoamer Elite M8 is a highly effective liquid product formulated to control foaming and priming in seawater distillation plants. Antifoam Defoamer Elite M8 has proven effectiveness during many years use in distillation plants throughout the world.

Product Application: 

The foaming tendency of seawater in distillation plants is unpredictable. It is generally thought that foam is formed when organic compounds are concentrated in the brine, giving rise to surface active effects which increase the liquid film strength at phase interfaces. Antifoam Defoamer Elite M8 is not soluble in water. At use concentrations (0.05 - 0.1 mg/l) Antifoam Defoamer Elite M8 forms a micro-emulsion and during evaporation is incorporated into the surface liquid film of bubbles where it acts as a surfactant and reduces the film strength. The result is that the film readily ruptures and a stable foam does not form. In this way a uniform boiling or flashing action is achieved and carry-over is minimised.

Product Procedure: 
Antifoam Defoamer Elite M8 can be used to control foaming in all types of seawater distillation plant and is particularly suitable for use in multi-stage flash plants. Antifoam Defoamer Elite M8 is a formulated product containing ethylene oxide / propylene oxide block copolymer. As such it is not soluble in water but readily forms a stable emulsion at concentrations up to 1% w/w in distillate. Antifoam Defoamer Elite M8 is typically dosed as a 1% w/w emulsion in distillate prepared as follows:
  • Add 50% - 70% of required distillate volume into dosing tank;
  • Start the dosing tank agitator/mixer;
  • Add the required Antifoam Defoamer Elite M8 volume into the dosing tank;
  • Add the remaining volume of distillate to give the required concentration of Antifoam Defoamer Elite M8 solution;
  • Continue agitation for a further 10 - 15 minutes;
  • The resulting emulsion will be stable and will not normally separate

Key Features and Benefits

  • Quick foam knockdown - particularly useful when foam suddenly builds up in the absorber and rapid control is needed.
  • Excellent stability at high temperatures - because of their excellent dispersibility. Antifoam Defoamer Elite M8 do not show a propensity to deposit on heat exchangers as many other antifoams tend to. Instead, they remain finely dispersed in the amine or glycol solution and are eventually filtered out.
  • Easy dilution and use - simple addition of water and minimum agitation is sufficient to dilute RXSOL-16-2066-200 antifoam emulsion to required concentrations. Pumping of the diluted emulsions is easy, due to their low viscosity.
  • Reduced clogging or scaling in the heat exchangers - potentially resulting in less service maintenance.
  • Low concentrations can provide effective foam control - RXSOL-16-2066-200 Antifoam Defoamer Elite M8 emulsion and often two to three times more effective than other antifoams used in treating units.

Product Safety, Handling and Storage

Customers should review the latest Material Safety Data Sheet (MSDS) and label for product safety information, safe handling instructions, personal protective equipment if necessary, and any special storage conditions required for safety.

<p> BELITE M-8 AntiFoam for SeaWater Distillation ANTISPUMIN DS ANTI FOAM, Antifoam for Seawater 210 Ltr</p>
Remarks: 

Low dose levels, typically in the range 0.05 to 0.1 mg/l in the seawater feed stream, depending on feed water quality. Activity is not dependent on temperature. No need to alter dose level if top brine temperature (TBT) changes. Negligible steam volatility and carry over into the distillate.

RXSOL-16-2066-200 is antifoam emulsion and its more concentrated antifoam emulsion. It has excellent candidates for controlling foam in amine and glycol dehydration units. This is suitable products for gas plants and have excellent stability in the presence of salts, resulting in reduced deposits on the plant’s equipment. RXSOL-16-2066-210  help preserves foam control under the severe conditions of a dehydrating unit. These conditions can remove water from other antifoam emulsions, rendering them immediately inactive.
