Summary on Grant Application Form |

Two problems encountered in the separation of gas-oil-water mixtures are the occurrence of foams and emulsions. Both heterogeneous mixtures result in increased cross entrainment and a significant reduction in plant capacity. Chemical additives are widely used to promote breakdown of both foams and emulsions. Due to cost implications, problems of contamination in downstream processing and environmental pollution implications it is necessary to minimise use of these additives. The current method of addition into upstream lines in not optimal and usually results in overusage. It is proposed to develop a novel addition/mixing system directly into the active zones in separator vessel. The method proposed is to predissolve the materials into a supercritical fluid. This will be added through a dispersion system into the active zone in the vessel. Flashing of this fluid will act as a propellant for the additive into foam as an intense spray. Candidate fluids are LPG and, for some cases, CO2. A critical feature of such a system will be sensor devices fitted along the vessel which detect the presence of the phases. Technology developed into a present project will provide these. A control strategy for the system will be developed.
