B01J 19/00

US Classification:

508552, 422224

Abstract:

The invention provides for a process for preparing a urea grease including: (a) introducing a first feed component to a first feeding zone; (b) introducing a second feed component to a second feeding zone; (c) first reacting-mixing in a first reacting-mixing zone; and (d) cooling-mixing in a cooling-mixing zone. The invention also provides for a process for preparing a urea grease including: (a) introducing a first feed component to a first feeding zone; (b) introducing a second feed component to a second feeding zone; (c) first reacting-mixing in a first reacting-mixing zone; (d) introducing a third feed component to a third feeding zone; (e) second reacting-mixing in a second reacting-mixing zone; and (f) cooling-mixing in a cooling-mixing zone.

Appl. No.:

8/584555

Inventors:

Ronald B. Harris - Livingston LA

International Classification:

B01D 2905

US Classification:

210804

Abstract:

A suitable liquid-solid separator tank having a bed with a drain, surrounding sides and a dividing wall. A grate overlays the interior of the vessel, bed, and sides, and forms the dividing wall. A filter overlays the grate, extending up the sides and overlapping the side grate and covering the dividing wall. The separator is filled with a sludge which is then separated from the liquid it contains by gravity and hydrostatic pressure which force the liquid through the filter. Liquid is drained out of the bottom of the vessel and the solids are transported within the vessel. The solids are removed through a gate that may be provided in the tank, or by using a hydraulic lift system in much the same manner as a garbage truck empties a municipal dumpster. The filter is removed with the solids and usually discarded.

Appl. No.:

8/451740

Inventors:

Ronald B. Harris - Livingston LA

International Classification:

B01D 2102

US Classification:

210138

Abstract:

The present invention provides an improved solids removal and concentrating unit. The solids removal and concentrating unit comprises a tank, an inlet line, an outlet line, and a sludge removal line communicating with the tank. The solids removal unit further has a plurality of linear baffles positioned in the tank forming a baffle row, with the baffles being positioned in a substantially vertical orientation. Finally, the tank further has a plurality of baffle rows. The baffles operate to reduce the velocity of a carrier liquid behind the baffles. The baffles also operate to form slight vortexes in the carrier liquid behind the baffles and thereby facilitate the downward movement of solids.

Assignee:

Shell Oil Company - Houston TX

International Classification:

B29B 0906

US Classification:

425 67

Abstract:

An improved underwater pelletizer adapted to prevent extruded material from agglomerating in an pelletizing assembly, which pelletizer includes a cutting assembly having (1) a shroud fixedly mounted to the surface of the recess in the center of the die ring thereby preventing pellets from being trapped between the die face and the cutting assembly; and (2) novel knives contoured to conform in their angular positions to the curvature of the shroud.

International Classification:

B01D 2400

US Classification:

210241

Abstract:

A portable liquid-solid separator tank having a bed with a drain, surrounding sides and a dividing wall. A grate overlays the interior of the vessel, bed, and sides, and forms the dividing wall. A filter overlays the grate, extending up the sides and covering the top and the dividing wall. The separator, which may be vacuum loadable, is filled with a sludge which is then separated from the liquid it contains by gravity and hydrostatic pressure which force the liquid through the filter. Liquid is drained out of the bottom of the vessel and the solids are transported within the vessel. The solids are removed through a gate that may be provided in the tank, or by using a hydraulic lift system in much the same manner as a garbage truck empties a municipal dumpster. The filter is removed with the solids and usually discarded.

Filed:

Feb 6, 1989

Appl. No.:

7/306700

Inventors:

Ronald B. Harris - Livingston LA

International Classification:

B01D 3530

US Classification:

210237

Abstract:

A portable liquid-solid separator for handling sludge in bulk with an upright vessel having a bed with a drain and surrounding sides. A grate overlays the interior of the vessel, bed and sides. A filter overlays the grate, extending up the sides and overlapping the side grate. The separator is filled with a sludge which is then separated by gravity filtration and the wicking action of the filter. Liquid is drained out the bottom of the vessel and the solids are transported within the vessel. In a preferred embodiment, the vessel is a bath tub style trailer with dumping capabilities.
