Low grade fugal pressurised feed system design and

The low grade fugals at Racecourse have always suffered from limited head pressure from the crystallisers due to the factory layout. In the past, to enable reasonable feeding of massecuite to the low grade fugal stage, excessive molasses dilution was always required. To overcome this problem, a pressurised feed system was proposed and installed. The upgrade of the LGF station at Racecourse involved the installation of a common dedicated reheater, massecuite transfer pump and associated distribution manifold to supply pressurised massecuite to the low grade fugals on the stage. This paper outlines the design, installation and operational experiences of this capital project.
