Appl. No.:

09/813747

Inventors:

Robert P. Mahoney - Newbury MA
Christopher B. Murphy - Clarendon Hills IL
Michael Dugan - Grand Rapids MI

Assignee:

Polymer Ventures, Inc. - Charleston SC

International Classification:

C02F 156

US Classification:

210725, 95152, 134 38, 162189, 210727, 210728, 210734, 210735, 210917, 210928, 210930, 423122

Abstract:

Aqueous suspensions of paints in waste waters can be treated to detackify the paint and facilitate its removal by contacting the paint suspension at a pH of from about 5 to about 14 with a polyarylamine that is produced by reacting an aldehyde with an arylamine in the presence of an acid in an aqueous suspension. The same polyarylamine can also be used for reducing the color content of highly colored liquids. Compositions containing the polyarylamine are also described.

B21F 45/24

US Classification:

428461, 428457, 59 71, 59 77

Abstract:

A thermally activated adhesive for coating and holding a multi-end band wire together through a high volume, high speed banding line which comprises a polyolefin in an amount of 2 to 98% by weight based upon the total weight of the adhesive, an acid in an amount of 1 to 20% by weight based upon the total weight of the adhesive and a rubber polymer in an amount of 1 to 20% by weight based upon the total weight of the adhesive. The adhesive activates in a temperature range of between 200 F. to 500 F. and is characterized in that it has a tensile strength of between 1,500 to 10,000 psi as determined by ASTM D638-96 and a peel strength of between 5 to 10 PLI as determined by ASTM D903-93.

Abstract:

Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a fluid waste stream following mining or ore processing operations.

International Classification:

B01D 21/01
B01D 21/02
B01D 21/26

US Classification:

210726, 210199

Abstract:

Disclosed herein are systems and methods for removing fine particulate matter from a fluid, comprising a separator that separates an inflow fluid stream into an overflow fluid path and an underflow fluid path, where the underflow fluid path is treated with a tethering material that attaches to the coarse particulate matter to form tether-bearing anchor particles and where the overflow fluid path is treated with an activating material so that the activating material interacts with the fine particulate matter to form activated particles. After these treatments, the underflow fluid path containing the tether-bearing anchor particles is comingled with the overflow fluid path containing the activated particles, so that a removable complex is produced that can be removed in a settling facility, thereby removing the fine particulate matter from the fluid. The systems and methods are particularly advantageous for removing particulate matter from a fluid waste stream following mining or ore processing operations, such as oil sands mining or processing.
