US Patent:
40394999, Aug 2, 1977
Filed:
Jun 25, 1975
Appl. No.:
5/590072
Inventors:
Edward F. Steigelmann - Park Forest IL
Robert D. Hughes - Park Forest IL
Joseph Gabor - Whiting IN
Assignee:
Standard Oil Company - Chicago IL
International Classification:
C08L 7706
US Classification:
260 296NR
Abstract:
Hollow membrane fibers are formed from a mixture of N-alkoxyalkyl polyamide, polyvinyl alcohol, di(lower alkyl) sulfoxide and water. The fibers are useful for separating chemicals, e. g. , aliphatically-unsaturated hydrocarbons, from mixtures containing them.

View page
US Patent:
39516210, Apr 20, 1976
Filed:
May 30, 1973
Appl. No.:
5/365204
Inventors:
Robert D. Hughes - Park Forest IL
Edward F. Steigelmann - Park Forest IL
Assignee:
Standard Oil Company - Chicago IL
International Classification:
B01D 5322
US Classification:
55 16
Abstract:
Novel separation film membranes are made with cross-linked hydrophilic polyvinyl alcohol and nylon, and the films contain complex-forming metal components which are active in the presence of water. The polyvinyl alcohol is cross-linked by reaction with a polycarboxylic acid. The invention includes the membranes, their method of manufacture, and the method of using them to separate one or more components of a gaseous mixture.

US Patent:
40146650, Mar 29, 1977
Filed:
Oct 7, 1974
Appl. No.:
5/512972
Inventors:
Edward F. Steigelmann - Naperville IL
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
C07C 1112
US Classification:
55 16
Abstract:
There is described an improved membrane-liquid barrier system of the type containing complex-forming, silver-containing ion component in an aqueous solution, and an improved process in which the membrane-liquid barrier combination can be employed to separate olefinically-unsaturated hydrocarbons. The membrane is in contact with an aqueous solution having dissolved therein complex-forming silver-containing ions, and further includes small but effective amounts of hydrogen peroxide to retard reduction of the ionic silver to elemental silver.

Method Of Converting Membrane Separation Units

US Patent:
42375967, Dec 9, 1980
Filed:
Oct 4, 1978
Appl. No.:
5/948339
Inventors:
Robert D. Hughes - Naperville IL
Edward F. Steigelmann - Naperville IL
Kemp R. Bunting - Wheaton IL
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
B22D 1910
B23P 600
US Classification:
294011
Abstract:
Method for the manufacture of membrane separation units suitable for the separation of components from mixtures containing them. These separation units can be made from elongated anisotropic hollow fiber membranes and can be used for the separation of olefinic compounds from saturated materials.

Inventors:
Edward F. Steigelmann - Park Forest IL
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
C10L 700
US Classification:
44 7A
Abstract:

Purification Of Olefin Recycle To Polymerization

View page
US Patent:
42359830, Nov 25, 1980
Filed:
Oct 4, 1978
Appl. No.:
5/948332
Inventors:
Edward F. Steigelmann - Naperville IL
Robert L. Yahnke - Naperville IL
Alistair S. Couper - Wheaton IL
Chand Deepak - Chicago IL
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
C08F 206
C08F 214
C07C 1104
US Classification:
526 68
Abstract:
Disclosed is a process for the polymerization of olefins wherein olefinic compounds are separated from mixtures containing them with resulting improved utilization of olefinic compounds. Such olefinic compounds are separated by use of membrane separation units and can be recycled to a polymerization zone.

Fluid Separation Process And Membrane

View page
US Patent:
40159558, Apr 5, 1977
Filed:
Feb 5, 1975
Appl. No.:
5/547217
Inventors:
Edward F. Steigelmann - Naperville IL
Charles S. Sokol - Cincinnati OH
Assignee:
Standard Oil Company - Chicago IL
International Classification:
C07C 1112
C07C 900
US Classification:
55 16
Abstract:
There is described an improved separation membrane-liquid barrier system of the type containing complex-forming, metal-containing ionic components, and an improved separation process in which the membrane-liquid barrier is employed. The membrane is in contact with an aqueous liquid barrier containing cuprous ions, such as a cuprous salt or a cuprous salt complex, e. g. a CuCl complex, preferably a CuCl--NH. sub. 4 Cl--HCl complex, and the barrier is in contact with a reducing agent that retards the complexing Cu. sup. + ion from being oxidized to Cu. sup. +. sup. 2. The reducing agent is relatively stable when positioned in the membrane and is not unduly oxidized by air nor does it unduly interfere with the essential function of the cuprous ions during the separation process. Elemental copper may function as a reducing agent that retards oxidation of Cu. sup. + ion to Cu. sup. +. sup. 2.

Use Of Aqueous, Non-Sweep Liquid During Membrane Separation

View page
US Patent:
42395062, Dec 16, 1980
Filed:
Jul 9, 1976
Appl. No.:
5/703942
Inventors:
Edward F. Steigelmann - Naperville IL
Robert D. Hughes - Naperville IL
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
B01D 5910
US Classification:
55 16
Abstract:
A material is separated from a fluid mixture by contacting the mixture containing the material with a first side of essentially solid, water-insoluble, hydrophilic, semi-permeable membrane in contact with an aqueous liquid barrier having ions which combine with the material to be separated to form a water-soluble complex. The partial pressure of the material on a second side of the semi-permeable membrane is sufficiently less than the partial pressure of the material in the mixture to provide separated material on the second side of the membrane. The separated material can be removed from the vicinity of the second side of the membrane by a gas stream. The second side of the membrane is contacted with an aqueous liquid medium to reduce the loss of the aqueous liquid barrier from the membrane which may otherwise decrease in separation efficiency during use due to water losses. The gas stream used to remove the separated material may be supersaturated with the aqueous medium, e. g. water, and may contact the membrane with the aqueous medium via condensation.
