Heat pump for wax plant

View inside a continuous, hydrocyclone wax melter using water for demonstration purposes.

The central vortex seen here was sucked down into the vortex finder at the tank base. We fixed this by placing a horizontal circular plate just below the air-liquid interface.

The centrifugal force in the melter made larger wax particles circulate at the vessel wall and only liquid wax was drawn into the vortex. The liquid then passed to an external heat exchanger before returning to the same tank as a tangential stream.

Three of the Biox team, James Quinn, Kate MacFarlane and Warren Oakes plus their teacher, do the cryptic crossword in the departure lounge at Adelaide airport, Chemeca 2010. Inveterate problem solvers one and all.
