Title: Method for separating solids suspended or entrained in a liquid

Abstract

A method of separating solids from a slurry or suspension is disclosed. The method includes: providing a slurry or suspension containing solids and liquid to an input port of a first side of a filter, the filter providing a filtering size between 2 microns and 70 microns; providing a liquid discharge port on a second side of the filter which receives the liquid that passes through the filter; and separating the solids from the liquid by pressing the solids into a pressure regulating solids discharge port on the first side of the filter, thereby compacting solids on the first side of the filter, forcing at least some of the liquid of the slurry or suspension through the first side of the filter to the second side of the filter causing pressure regulated solids to be discharged through a pressure regulating solids discharge port into a pressurized chamber.

Methods for separating non-fibrous solids from liquids using a double-roller

Patent Baxter, Larry; Davis, Nathan

A method for separating solids from liquids is disclosed. A double-roller system is provided. A process fluid is provided to the double-roller system. The process fluid comprises a suspended solid and a process liquid. The suspended solid comprises non-fibrous solid particles. A portion of the process fluid is compressed through the double-roller system to produce a compressed portion of the suspended solid. A product stream and a dilute fluid stream are separated. The product stream comprises a compressed portion of the suspended solid and a first portion of the process liquid. The dilute fluid stream comprises a second portion ofmore » « less

Method for separating liquid and solid products of liquefaction of coal or like carbonaceous materials

Patent Malek, John M [P.O. Box 71, Lomita, CA 90717]

A method of improving the quality of slurry products taken from coal liquefaction reactors comprising subjecting the slurry to treatment with an alkaline compound such as caustic soda in the presence of steam in order to decompose the phenolic and acidic materials present in the slurry, and to also lower the slurry viscosity to allow separation of solid particles by sedimentation.

Method for solid-liquid separations

Patent Baxter, Larry; Frankman, David; Chamberlain, Skyler; ...

Devices, systems, and methods are disclosed to separate solids from liquids. A vessel includes a screw, an inlet, a first outlet, and a second outlet. The inlet receives a first slurry having an incoming solids concentration. The first slurry consists of solids and a contact liquid. The first outlet is disposed toward the first end of the vessel. The second outlet is disposed toward a second end of the vessel. The screw preferentially conveys the solids over the contact liquid towards the second end of the vessel, the solids displacing at least a portion of the contact liquid, causing thatmore » « less

Method and apparatus for acoustically monitoring the flow of suspended solid particulate matter

Patent Roach, Paul D [Darien, IL]; Raptis, Apostolos C [Downers Grove, IL]

A method and apparatus for monitoring char flow in a coal gasifier system cludes flow monitor circuits which measure acoustic attenuation caused by the presence of char in a char line and provide a char flow/no flow indication and an indication of relative char density. The flow monitor circuits compute the ratio of signals in two frequency bands, a first frequency band representative of background noise, and a second higher frequency band in which background noise is attenuated by the presence of char. Since the second frequency band contains higher frequencies, the ratio can be used to provide a flow/nomore » « less

Lined sampling vessel including a filter to separate solids from liquids on exit

Patent Shurtliff, Rodney M [Idaho Falls, ID]; Klingler, Kerry M [Idaho Falls, ID]; Turner, Terry D [Ammon, ID]

A filtering apparatus has an open canister with an inlet port. A canister lid is provided which includes an outlet port for the passage of fluids from the canister. Liners are also provided which are shaped to fit the interiors of the canister and the lid, with at least the canister liner preferably being flexible. The sample to be filtered is positioned inside the canister liner, with the lid and lid liner being put in place thereafter. A filter element is located between the sample and the outlet port. Seals are formed between the canister liner and lid liner, andmore » « less
