Abstract
This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by using a mechanical device to separate the solids from the liquids based on a density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.
Claims18
A method for separating components in a fractionated process stream, the method comprising:
- receiving the fractionated process stream from a production facility, where the fractionated process stream comprises a mixture of components of liquids and solids;
- adding a non-condensable media to the mixture of components to increase a density differential between the components,
- separating the solids from the liquids in the mixture of components with a first mechanical separation device, to provide a separated solids stream and a separated liquids stream, wherein the separated solids stream is approximately 10% to approximately 40% total solids, and
- sending the separated liquids stream through a second mechanical separation device, to create a suspended solids concentrate from the separated liquids stream.

A method for processing a stream, the method comprising:
- receiving a process stream from a production facility, the process stream comprising a mixture of one or more liquids and one or more solids;
- adding a non-condensable media to the mixture of the process stream to increase a density differential between the one or more solids and the one or more liquids;
- and
- separating the one or more solids from the one or more liquids in the mixture with a mechanical separation device based on a difference in density between the one or more solids and the one or more liquids, to provide a separated solids stream and a separated liquids stream, wherein the separated solids stream is at least approximately 38% protein.
1 more element
A method comprising:
- receiving a process stream comprising a mixture of one or more liquids and one or more solids:
- adding a non-condensable media to the mixture of the process stream to increase a density differential between the one or more solids and the one or more liquids, and
- separating the one or more liquids from the one or more solids in the process stream using at least one of a sedicanter centrifuge, a decanter centrifuge, a disk stack centrifuge, a hydrocyclone, or a settling tank to create a light emulsion phase and a heavy phase with suspended solids, wherein the light emulsion phase comprises from about 20% to about 55% total solids.
