Abstract
A process is disclosed which includes separating selected solids from a process stream with a selected solids mechanical processor containing a filter to produce a filtrate substantially free of selected solids and a retentate containing recovered selected solids. In one embodiment, the process stream contains an increased amount of liquid is provided to a downstream mechanical processor as compared to a process stream having no selected solids mechanical processor upstream. The selected solids mechanical processor can be a dynamic filtration device or a static separation device. Bio-oil recovery efficiency, quantity, and quality can be improved as a result.
Claims13
A process used in an ethanol production facility, the process comprising:
- separating selected solids from a process stream in the ethanol production facility to yield a liquid substantially free of the selected solids, wherein the selected solids comprises suspended particles having a buoyancy wherein the suspended particles accumulate at an interface between light/oil and aqueous/heavy phases;
- and
- then passing the process stream through a selected solids mechanical processor to produce a filtrate substantially free of the selected solids and a retentate containing recovered selected solids, wherein the mechanical processor includes a dynamic filtration device which compresses the process stream by structure movable relative to a filter surface against a filter for a time sufficient to further decrease an amount of liquid retained in the retentate.
