Water Treatment, Oil & Gas

BRB Akasil® defoamers are widely used by the water treatment and oil & gas industries. They provide effective foam control solutions in water and wastewater treatment and assist in the hydrocarbon extraction process, oil and gas production and in a host of refinery operations in the oil & gas industry.

BRB manufactures defoaming agents to eliminate foam generated by both industrial and municipal water treatment processes. BRB range of Silicone based defoamers have the following advantages:-
  • Silicone defoamers have greater defoaming efficacy than organic defoamers due to its lower surface tension
  • Silicone defoamers have long lasting effects than other defoaming agents and also effective in preventing foam formation
  • Silicone defoamers have good heat and chemical resistance and thus effective with all types of foams
  • Silicone is chemically inert thus extremely stable and does not react with other substances
BRB Akasil® TG range of antifoams is specially designed for water treatment to minimise their impact on the environment and present a low chemical oxygen demand.

Foam often occurs in oil & gas production processes. High injection pressures and process aids contribute to air entrainment in drilling fluids and cementing well-bore linings. BRB Akasil® Antifoam RE 20 offers the appropriate chemical resistance to prevent the formation of troublesome foam in these activities. Crude oil contains significant volumes of dissolved gases, stabilised by high subterranean pressures. At production, where the crude oil passes through gas-oil separators, under normal atmospheric conditions, these are coalesced resulting in high levels of unwanted foam. A range of water-free defoamers based on high viscosity BRB silicone oils are used to great effect.

Foam also appears in other petrochemical operations such as cracking, delayed coking and asphalt processing. BRB Akasil® range of solvent based antifoam has been successfully formulated as a refinery antifoam to ensure swiftest hydrocarbon process rates.
