Abstract
A method that includes clarifying a thin stillage product in a mechanical processor to produce a fine suspended solids stream and a clarified thin stillage is provided. The method further includes providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, each stream having a reduced amount of suspended solids and a lower viscosity as compared to process streams having a comparable total solids content but containing a higher amount of suspended solids. The method can further included further processing of one or more of the reduced suspended solids streams to produce a bio-oil product.
Claims28
A method comprising:
- clarifying a thin stillage product in a centrifugal device to produce a fine suspended solids stream and a clarified thin stillage;
- and
- providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, wherein the one or more reduced suspended solids streams have a reduced amount of suspended solids of less than about 25% by weight of a total solids content and a lower viscosity as compared to thin stillage having suspended solids of about 25% to about 75% by weight of a total solids content, which contains a higher amount of suspended solids.
A method comprising:
- providing a thin stillage having a suspended solids content of about 25% to about 75% by weight of a total solids content;
- clarifying a thin stillage product in a centrifugal device to produce a fine suspended solids stream and a clarified thin stillage;
- providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce at least two reduced suspended solids streams, wherein the at least two reduced suspended solids streams have a reduced amount of suspended solids of less than 25% by weight of a total solids content compared to the thin stillage, which contains a higher amount of suspended solids;
- and
- subjecting at least one of the at least two reduced suspended solids streams to mechanical processing to produce a bio-oil product.
A method comprising:
- increasing temperature of a thin stillage product, wherein the thin stillage product contains thin stillage and clarified thin stillage;
- and
- clarifying the thin stillage product to produce one or more suspended solids streams, wherein the one or more suspended solids streams have a total solids content between about 30% and about 90% by weight, wherein the total solids content comprises suspended solids and dissolved solids, and the suspended solids comprise less than 25% by weight of the total solids content.
A method for reducing a dryer load in a bio-product production facility comprising:
- providing a thin stillage product having a suspended solids content greater than about 25% of a total solids content;
- clarifying the thin stillage product in a centrifugal device to produce a fine suspended solids stream and a clarified thin stillage;
- providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, wherein the one or more reduced suspended solids streams have a reduced amount of suspended solids of less than about 25% by weight of a total solids content;
- and
- reducing the dryer load as compared to a method performed without a clarifying step of the thin stillage product.
A method for improving bio-product production yield comprising:
- providing a thin stillage product having a suspended solids content of greater than 25% of a total solids content;
- clarifying the thin stillage product in a centrifugal device to produce a fine suspended solids stream and a clarified thin stillage;
- and
- providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, wherein the one or more reduced suspended solids streams have a reduced amount of suspended solids of less than about 25% by weight of a total solids content as compared to the thin stillage product, wherein bio-product production yield is increased as compared to a method performed without a clarifying step of the thin stillage product.
A method of reducing emissions in a bio-product production facility comprising:
- providing a thin stillage product having a suspended solids content of about 25% to about 75% by weight of a total solids content;
- clarifying the thin stillage product in a mechanical processor to produce a fine suspended solids stream and a clarified thin stillage;
- and
- providing the thin stillage product and the clarified thin stillage, in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, wherein the one or more reduced suspended solids streams have a reduced amount of suspended solids of less than about 25% by weight of a total solids content, wherein emissions from the bio-product production facility are reduced as compared to a method performed without a clarifying step of the thin stillage product.
