Abstract
An improved process for clarifying sugar syrup in the flotation system of a sugar making operation. Neutral phosphate-based compounds are added to the flotation system to aid in clarifying the sugar syrup. The use of the neutral phosphate-based compounds will eliminate the use of phosphoric acid and the commensurate need for neutralizing chemical as well as elimination of the tanks for phosphoric acid and neutralizing chemical mixing at field installations.
Claims17
A process for clarifying sugar syrup during a sugar making operation comprising adding to the syrup an effective clarifying amount of at least one of water soluble tripolyphosphates, pyrophosphates and hexametaphosphates.
A process for clarifying sugar syrup during a sugar making operation comprising adding to the syrup in a flotation system of the sugar making operation an effective clarifying amount of at least one water soluble compound that will not substantially decrease the pH of the syrup, the at least one water soluble compound comprising at least one of tripolyphosphates, pyrophosphates and hexametaphosphates, and adding at least one anionic polymer to the syrup subsequent to addition of the at least one water soluble compound.
