Liquid-Liquid Contacting System

View page
US Patent:
42475210, Jan 27, 1981
Filed:
Aug 15, 1979
Appl. No.:
6/066853
Inventors:
Paulino Forte - Yonkers NY
George S. Somekh - New Rochelle NY
Assignee:
Union Carbide Corporation - New York NY
International Classification:
B01D 1200
US Classification:
422256
Abstract:
A liquid-liquid contacting tray comprising a perforated deck providing a major portion of the tray surface area and continuous phase liquid transfer means comprising a settling section extending outwardly from the tray deck on one side of the tray and joined in closed flow communication with a smaller cross-sectioned pressure drop section extending outwardly from the tray deck on the other side of the tray to provide a sudden contraction in cross-sectional area from the settling section to said pressure drop section substantially in the plane of the perforated deck for reduction of pressure in the liquid flowed therethrough.

Separation Of Aromatic Hydrocarbons From Petroleum Fractions

US Patent:
42604761, Apr 7, 1981
Filed:
Jan 31, 1980
Appl. No.:
6/117295
Inventors:
Jose A. Vidueira - White Plains NY
Paulino Forte - Yonkers NY
George S. Somekh - New Rochelle NY
Assignee:
Union Carbide Corporation - New York NY
International Classification:
C10G 2128
US Classification:
208321
Abstract:
An improvement to a continuous solvent extraction-steam-distillation process for the recovery of aromatic hydrocarbons in the range of C. sub. 6 -C. sub. 16 from a feed stream containing such aromatics and aliphatic hydrocarbons in the range of C. sub. 5 -C. sub. 16 which resides in using two extractive distillation zones thermally linked to recover heat and solvent, thereby resulting in a heat savings.

US Patent:
43460151, Aug 24, 1982
Filed:
Aug 14, 1980
Appl. No.:
6/177909
Inventors:
George S. Somekh - New Rochelle NY
Robert A. Cupper - Ridgefield CT
Assignee:
Union Carbide Corporation - Danbury CT
International Classification:
C10M 132
US Classification:
252 50
Abstract:
The lubricating characteristics of high temperature fluids used in Rankine Cycle and heat pump systems has been enhanced by incorporating therein heterocyclic arenes containing 8 to about 18 ring carbon atoms and an average of 1 to 2 ring nitrogen or S atoms per arene, and optionally 1 to 2 ring O atoms with substituents such as alkyl, amino, keto oxygen or hydroxyl groups.

Process For The Recovery Of Amides

View page
US Patent:
40136400, Mar 22, 1977
Filed:
Apr 11, 1974
Appl. No.:
5/459968
Inventors:
George S. Somekh - New Rochelle NY
Assignee:
Union Carbide Corporation - New York NY
International Classification:
C07D20116
US Classification:
2602393A
Abstract:
A solvent extraction-distillation process for the recovery of a water-soluble aliphatic amide having 1 to 8 carbon atoms or mixtures thereof from an aqueous solution wherein the concentration of the amide is in the range of about 0. 25 percent by weight to about 25 percent by weight, based on the weight of the solution, and the solvent is a compound having the following structural formula: ##STR1## wherein M is OH or CH. sub. 2 OH, R is hydrogen or an alkyl radical, there being at least one alkyl radical, and the total number of carbon atoms in all of said alkyl radicals taken together is 3 to 12, or a mixture of isomers thereof, Said compound or mixture of isomers having a boiling point higher than the amide and less than about 350. degree. C. and being non-azeotropic with the amide, Comprising the following steps: (a) contacting the solution in an extraction zone with the solvent to provide an extract comprising solvent, amide, and no more than about 5 percent by weight of water based on the weight of the solution and a raffinate comprising at least about 95 percent by weight of water based on the weight of the solution and less than about 5 percent by weight of solvent based on the weight of the solvent; (b) introducing the extract from step (a) into a distillation zone wherein the pressure is less than about 500 millimeters of mercury and the temperature is less than the decomposition temperatures of the amide and the solvent at said pressure, to separate the solvent from a mixture of amide and water; and (c) recovering the mixture of amide and water.

Separation Of Alkanols From Aqueous Reaction Solutions

US Patent:
44827687, Nov 13, 1984
Filed:
Mar 31, 1983
Appl. No.:
6/480702
Inventors:
George S. Somekh - New Rochelle NY
Assignee:
Union Carbide Corporation - Danbury CT
International Classification:
C07C 2980
C07C 2986
C07C 2976
US Classification:
568918
Abstract:
Purified isopropanol is obtained from a crude reaction mixture by removing high boiling oils with activated carbon, extraction with a high boiling solvent and distillation with energy saving use of distillation vapors to heat successive distillation steps. Recyle of components also improves the overall economics of the process.

Process For The Separation Of Aromatic Hydrocarbons From A Mixed Hydrocarbon Feedstock

View page
US Patent:
39665895, Jun 29, 1976
Filed:
Mar 17, 1975
Appl. No.:
5/559077
Inventors:
George Solomon Somekh - New Rochelle NY
Assignee:
Union Carbide Corporation - New York NY
International Classification:
C10G 2128
US Classification:
208321
Abstract:
A continuous solvent extraction-steam distillation process for the recovery of aromatic hydrocarbons having boiling points in the range of about 80. degree. C. to about 175. degree. C. from a feedstock containing aliphatic hydrocarbons and said aromatic hydrocarbons comprising the following steps: A. introducing the feedstock into an extraction zone at about the midpoint thereof; B. introducing a mixture of water and solvent into the extraction zone at about the top of said extraction zone, said solvent being a water-miscible organic liquid having a boiling point of at least about 200. degree. C. ; c. introducing reflux hydrocarbons into the extraction zone at about the bottom thereof; D. contacting the feedstock in the extraction zone with the mixture of water and a solvent, the water phase of step (j), and the reflux hydrocarbons to provide an extract comprising aromatic hydrocarbons, reflux aliphatic hydrocarbons, solvent, and water and a raffinate comprising essentially aliphatic hydrocarbons; E. contacting the extract with steam in a distillation zone to provide an overhead distillate comprising a reflux hydrocarbons phase and a water phase, a side cut distillate comprising an aromatic hydrocarbons phase and a water phase, and bottom comprising a mixture of solvent and water; F.
