Process For Clarification Of Oil-Containing Waste

View page
US Patent:
40595153, Nov 22, 1977
Filed:
Mar 18, 1977
Appl. No.:
5/779193
Inventors:
William J. Fowler - Berlin NJ
Richard A. Heberle - Holland PA
Richard G. Tonkyn - Cornwells Heights PA
Norman Vorchheimer - Buckingham PA
Assignee:
Betz Laboratories, Inc. - Trevose PA
International Classification:
B01D 1702
US Classification:
210 51
Abstract:
The present disclosure is directed to a process of separating oil from oil-containing wastewater which comprises treating the wastewater with a water-soluble cationic polymer obtained by the polymerization of an epihalohydrin with an alkylene polyamine having the formula ##STR1## wherein R is a lower alkylene having from 2 to about 6 carbon atoms, and R. sub. 1 and R. sub. 2 are each a lower alkyl of from 1 to about 6 carbon atoms.

US Patent:
39533301, Apr 27, 1976
Filed:
Oct 6, 1975
Appl. No.:
5/619767
Inventors:
Richard G. Tonkyn - Cornwells Heights PA
Norman Vorchheimer - Buckingham PA
William J. Fowler - Berlin NJ
Richard A. Heberle - Holland PA
Assignee:
Betz Laboratories, Inc. - Trevose PA
International Classification:
C02B 120
US Classification:
210 52
Abstract:
The present disclosure is directed to novel water-soluble cationic polymers and their use either alone or in conjunction with coagulant aids to flocculate or coagulate matter suspended in aqueous systems. The novel polymer is prepared by reacting an alkylene polyamine with an epihalohydrin under specific conditions which include the incremental reaction of the epihalohydrin to fully react with the epihalohydrin and attain a polymer of uniform viscosity.

Cationic Chlorine-Resistant Polymeric Flocculants And Their Use

US Patent:
40886131, May 9, 1978
Filed:
Jan 2, 1976
Appl. No.:
5/646298
Inventors:
Richard G. Tonkyn - Cornwells Heights PA
Norman Vorchheimer - Buckingham PA
Assignee:
Betz Laboratories, Inc. - Trevose PA
International Classification:
C08G 2312
C02B 120
US Classification:
260 2BP
Abstract:
Cationic, chlorine-resistant polymeric materials, useful as flocculants, are prepared by reacting an epihalohydrin with a mixture consisting of a lower di-alkylamine and ammonia, where the molar ratio of the amine to ammonia is from about 5:1 to about 2:1, and the ratio of the epihalohydrin to the amine-ammonia mixture is from about 0. 9 up to the functional equivalency of the amine mixture, for a time and at temperature conditions such that the resultant polymeric material has a viscosity of about 50 cps to about 4000 cps (Brookfield, spindle 1, 12 rpm) at about 50% real solids content.

US Patent:
41183550, Oct 3, 1978
Filed:
Apr 17, 1978
Appl. No.:
5/896949
Inventors:
Norman Vorchheimer - Buckingham PA
Assignee:
Betz Laboratories, Inc. - Trevose PA
International Classification:
C08L 3326
US Classification:
260 296PT
Abstract:
A polymer in convenient liquid form is disclosed which comprises a mixture of the polymer with a first solvent in which the polymer is soluble and a second solvent which is co-soluble with the first solvent and in which the polymer is not soluble. A method for forming the polymer in convenient liquid form is also disclosed.
