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 and XP 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.
