Abstract

A method for clarifying a process fluid is disclosed. The process fluid is provided to a transport device. The process fluid comprises a process liquid that entrains a first solid of a first average particle size. A second solid of a second average particle size is provided to the transport device. The second average particle size is larger than the first average particle size. The process fluid passes through the second solid. The first solid adsorbs to, deposits on, fuses with, or is trapped by the second solid, producing a first solid-depleted process fluid and a first solid-loaded second solid. The first solid-loaded second solid is removed from the transport device continuously. The second solid is reconstituted from a portion of the first solid-loaded second solid. The second solid is recycled to the transport device. In this manner, the process fluid is clarified.

Description

This invention was made with government support under DE-FE0028697 awarded by The Department of Energy. The government has certain rights in the invention.

FIELD OF THE INVENTION

This invention relates generally to solid/liquid separation. More particularly, we are interested in removing solids from liquids continuously.

BACKGROUND

Removing solids from liquids is a unit operation common to almost all heavy industries. Whether the process requires the removal of biomass and dirt from water, solid carbon dioxide from a cryogenic liquid, or dust from oil, solid/liquid separation is a constant. Filter presses, thickeners, clarifiers, and other devices all separate solids. A common technique for removing fine solids is sedimentation filtration. The filtering media is exclusively sand or similar granular bulk materials.
U.S. Pat. No. 6,143,186, to Van Unen, teaches a device for continuous filtration of liquids. A liquid with dirt to remove is fed through one wall of a vertical sedimentation filter using bulk material as a filter media, and is removed from the opposite wall of the sedimentation filter. The bulk material, now with dirt entrained on it, is suctioned into a separations device which recycles the bulk material into the chamber and discharges the dirt. The present disclosure differs from this disclosure in that the chamber is required to be rectangular, inlets and outlet are required to be in the walls, a portion of the liquid being filtered is used to remove the bulk material and dirt during the suction step, and the entire process is limited to ambient conditions. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.
U.S. patent Ser. No. 13/409,856, to Self, et al., teaches various methods for lowering levels of carbon dioxide and other atmospheric pollutants. Gravity separation of carbonates or bicarbonates is conducted gravity separation, mechanical separation, and thermal evaporation. Optionally, flocculation and other methods of crystal growth are utilized. The present disclosure differs from this disclosure in that no sedimentation filtration or similar utilized. Further, there is no process to separate the larger carbonates and bicarbonates from their flocculants or similar, to reuse them for further separation. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.
U.S. Pat. No. 6,942,807, to Meng, et al., teaches a water filtration device and method for removing heavy metals and organic compounds from water. An iron filter is provided for precipitating the heavy metals and a sand filter for removing the heavy metals and organic compounds. The iron filter is vibrated or otherwise agitated to cause the precipitates to be removed from the iron. The present disclosure differs from this disclosure in that two stages of filtration are required, the sand filter is not continually recycled for reuse, and vibration is required. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.
In Microfiltration (Martin, J. F. et al. 1991. J. Air Waste Manage. Assoc. 41:1653-1657) and adsorption and magnetic filtration (Chen, W. Y. et al. 1991. Res. J. Water Pollut. Control Fed. 63:958-964), an adsorption and magnetic filtration process is disclosed. Heavy metals are adsorbed onto fine magnetic particles coated with ferrihydrite. The magnetic particles are then collected using a magnetic filter. Finally, the magnetic particles are regenerated by metal desorption and then reused. The present disclosure differs from this disclosure in that magnetic filtration and metal desorption are required in order to accomplish the filtration and recycling. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.
U.S. Pat. No. 7,247,245, to Proulx, et al., teaches a filtration cartridge and process for filtering a slurry. A filter cartridge is used for filtering solids from a slurry. The present disclosure differs from this disclosure in that the filter cartridge has to be replaced when full. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.
U.S. Pat. No. 5,900,159, to Engel, et al., teaches a method for separating a liquid from a slurry in the presence of a gas. The slurry is degasified and then separated through a cross-flow filter. The present disclosure differs from this disclosure in that a cross-flow filter is required. This disclosure is pertinent and may benefit from the methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.

SUMMARY

A method for clarifying a process fluid is disclosed. The process fluid is provided to a transport device. The process fluid comprises a process liquid that entrains a first solid of a first average particle size. A second solid of a second average particle size is provided to the transport device. The second average particle size is larger than the first average particle size. The process fluid passes through the second solid. The first solid adsorbs to, deposits on, fuses with, or is trapped by the second solid, producing a first solid-depleted process fluid and a first solid-loaded second solid. The first solid-loaded second solid is removed from the transport device continuously. The second solid is reconstituted from a portion of the first solid-loaded second solid. The second solid is recycled to the transport device. In this manner, the process fluid is clarified.

The frozen condensable or absorbed gas may comprise carbon dioxide, nitrogen oxide, sulfur dioxide, nitrogen dioxide, sulfur trioxide, hydrogen sulfide, hydrogen cyanide, or combinations thereof. The frozen condensable or absorbed gas or gases derive from vitiated flows, producer gases, or other industrial flows, wherein the vitiated flows are produced from coal, biomass, natural gas, oil, and other common fuels. The first solid may further comprise particulates, mercury, other heavy metals, condensed organics, soot, inorganic ash components, other impurities common to the vitiated flows, the producer gases, or the other industrial flows, or combinations thereof
The transport device may comprise a conveyor belt, bucket elevator, circulating fluidized-bed, hail tower, screw conveyor, leach tank, flow channel, tube, porous filter, screen filter, or channel.
