Highly effective liquid antifoam formulated for controlling foaming and priming in seawater distillation plants compatible with most antiscalants
New Generation with advanced formulation Antifoam Defoamer AF10 is a highly effective liquid product formulated to control foaming and priming in seawater distillation plants. Antifoam Defoamer AF10 has proven effectiveness during many years use in distillation plants throughout the world.
Antifoam for Seawater Desalination systems or other aqueous systems by RXSOL is a high-performance antifoam formulation based on a synergistic blend of modified alcohols and polymerised glycol ethers, specifically developed to control foam formation in seawater intake, pretreatment, and desalination systems.
The product rapidly collapses existing foam while providing extended foam suppression in seawater streams containing natural organic matter, algae-derived surfactants, hydrocarbons, biological contaminants, and suspended solids. The combination of fast-acting antifoam component and persistent foam-control properties of the polymerised glycol ether delivers both immediate knockdown and long-lasting antifoam performance.
The product is designed for continuous or intermittent injection into seawater make-up lines to minimize operational problems associated with foaming in desalination plants.
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 AF10 is not soluble in water. At use concentrations (0.05 - 0.1 mg/l) Antifoam Defoamer AF10 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.
Where to use ANTIFOAM AF10 for foam knockdown?
- Reverse Osmosis (RO) Plants
- Multi-Stage Flash (MSF) Plants
- Multi-Effect Distillation (MED) Plants
- Hybrid Desalination Facilities
- Intake Channels
- Seawater Make-up Lines
- Pumping Stations
- Equalization Basins
- Clarifiers
- Dissolved Air Flotation (DAF) Units
- Pretreatment Systems
- Power Plant Cooling Water Intakes
- Refinery Seawater Systems
- Petrochemical Facilities
- Offshore Platforms
- LNG Terminals
- Add 50% - 70% of required distillate volume into dosing tank;
- Start the dosing tank agitator/mixer;
- Add the required Antifoam Defoamer AF10 volume into the dosing tank;
- Add the remaining volume of distillate to give the required concentration of Antifoam Defoamer AF10 solution;
- Continue agitation for a further 10 - 15 minutes;
- The resulting emulsion will be stable and will not normally separate
The dose level required will depend on the quality of the seawater feed (e.g. dissolved organics, suspended solids) but is typically found to be in the range 0.05 to 0.1 mg/l and is subject to optimisation as operating experience is gained. Dose level is not dependent on operating temperature of the distillation plant. Recommended injection points are either into the seawater make-up line after any external de-aeration and decarbonation equipment, or into the recycle brine stream at a suitable point after the blowdown and typically into the discharge of the recycle brine pump.
General-purpose antifoams have a wide range of applicability, but not all of them are suitable for use in the treatment. Some foam control agents can aggravate the problem. Foam control in gas scrubbers is only one of the process parameters to be monitored. It is equally important to prevent or slow the fouling of the unit, because dismantling of the gas-scrubbing units is manually intensive. Incorrectly specified antifoams can easily lead to increased fouling and clogging, particularly in the heat exchangers. Momentive Performance Materials RXSOL antifoams are designed to provide foam control with a minimum of such problems.

RXSOL-51-2066-220 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-51-2066-220 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.
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 AF10 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-51-2066-220 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-51-2066-220 Antifoam Defoamer AF10 emulsion and often two to three times more effective than other antifoams used in treating units.
