A method of manufacturing pulp using corn stalks may include cutting the corn stalks into pieces having a length of 10 to 60 mm, separating and discharging the cut corn stalks into rind and pith using a separation unit while crushing the cut corn stalks, pretreating the corn stalks by filtering the rind and pith of the corn stalks and flakes of the rind, removing a portion of hemicellulose of the rind, and cooking the rind from which the portion of hemicellulose has been removed, using caustic soda and sodium carbonate.

A rotor core is provided that includes a rotor length defined along an axis of rotation and a plurality of separation channels. The plurality of separation channels having a channel length extending along the axis of rotation a distance that is less than the rotor length. A rotor assembly is also provided that includes such a rotor core removably disposed in an outer housing.

Provided is a rotating assembly. The rotating assembly is for forming a microstructure, and comprises: a rotating body rotatable about a rotary shaft; a first support member installed on the rotating body so as to be spaced apart from the rotational shaft and having a predetermined viscous composition disposed on an outer surface thereof; and a fluid communicating portion for communicating the inside and the outside of the rotating body, wherein when the rotating body rotates, the viscous composition is pulled in a radially outward direction of the rotary shaft, and the pulled viscous composition is cured through the fluid communicating portion, thereby forming a microstructure.

A centrifuge separator device for use in mining gold ore receives bulk quantities of gold bearing materials through a port in a central vertical pipe, diverting the materials through a series of rotating baffles into a multi-tiered bowl, with a variable speed bowl drive system turning the bowl and the baffles at a selected speed while framework, including a channeled bin, gussets and a plurality of blades extending a plurality of upper and lower cutters, remains stationary, forcing the materials to separate by density, forcing the lighter materials up and over the rotating bowl into a channeled bin for further disposal through an exit port in the channeled bin, leaving the heavier gold bearing ores in the lower part of the bowl for collection and further classification.

A solid-liquid separator for separating a solid phase from a liquid phase in a solid-liquid mixture is provided. The solid-liquid separator includes a basket and filter assembly housed coaxially within a tank such that when the basket and filter assembly rotates the liquid phase moves through the filter of the basket and filter assembly into the tank and is discharged from the solid-liquid separator. The solid phase is retained on the filter of the basket and filter assembly and travels vertically up the filter of the basket and filter assembly where it is discharged from the solid-liquid separator.

Seawater is deaerated using a rotating packed bed device having one or more rotatable packing rings within a housing, a liquid inlet for infusing seawater into an interior region defined by the packing rings, a gas outlet for accepting gas which has passed radially inwardly through the packing rings and removing the gas from the interior region, and a liquid outlet for removing a deaerated seawater stream from the housing. A shaft coupled to a motor drives the packing rings causing the packing rings to rotate. The feed seawater stream passes radially outwardly through each of the packing rings thereby forming the deaerated seawater stream having a lower concentration of oxygen, air and/or carbon dioxide therein than the feed seawater stream and a gas stream having been removed from the feed seawater stream. The deaerated seawater stream is then injected into a hydrocarbon producing reservoir in an EOR process.

A centrifuge (1) for separating intermixed particulate material of different specific gravity. The centrifuge (1) comprising a centrifuge bowl (10) having a plurality of annular recesses (19), a housing (30), an inlet (17), and means for rotating the centrifuge bowl (10) about the central axis (15). An annular cavity (31) is defined between the housing (30) and the centrifuge bowl (10). The annular cavity (31) is fluidly connected to the plurality of annular recesses (19) on the inner surface of the centrifuge bowl by a number of perforations in the centrifuge bowl wall (12). The annular cavity (19) has a fluid inlet to provide fluid into the annular cavity. The annular cavity (19) has an accumulated cross-sectional flow area (A.sub.flow) at two different heights in the annular cavity that differs by at least a factor 10.

Cell separation systems and methods of separating cells are disclosed. In an embodiment, a cell separation system is described that comprises a non-transitory storage device that executes a centrifugation program to separate cell volume from biologic material volume; a heating mechanism; a containment mechanism; and an assembly comprised of a single-walled centrifugation bowl. In an embodiment, methods of separating cells are disclosed whereby cells are separated by agitating a volume of biologic material and a volume digestion media to form a digested volume of biologic material; centrifuging the digested volume of biologic material; removing a portion of a resulting waste via at least one fluid outlet; isolating a different portion of the waste, and removing the concentrated cell volumes from the reservoir.
