Our extensive experience with gravity separators employs physical scaled models & computational simulation techniques to develop, test, and optimize designs for our clients’ applications regardless of which type of vessel geometry they use:
• Deep-cone vessel design / optimization
• Shallow-cone vessels with rotating rakes
• Flotation cells
• Inclined plate separators
By combining computational simulation and physical modelling, it is possible to study a wide range of scenarios. For example, an approach to physical modelling of solid-liquid separation we often employ is using scaled laboratory models with carefully selected analog solids & liquids to match the important physics obtained from a dimensional analysis of the problem. In the lab, solid phases can be modelled with solid glass beads, hollow glass spheres, or polymer particles with the sizes tuned to match the scaled test vessel. Water, hydrocarbons, or silicone oils can be used as the liquid phase. Temperature, surfactant & additives can be used to obtain a wide range of viscosity, density & surface tension properties.
The solutions Coanda has developed have allowed our customers to improve their gravity separation process performance, reduce costs, de-bottleneck & adapt to changes.
