Title: Treatment of Sour Hydrocarbon Streams.
IPC: C10G19/04
Filed: 1966-10-31
Abstract: 1,159,926. Desulphurizing hydrocarbons. HOWE-BAKER ENGS. Inc. 31 Oct., 1966 [1 Dec., 1965], No. 48717/66. Heading C5E. A process of treating a sour hydrocarbon stream containing sulphur components including at least 50 p.p.m. mercaptans and at least one other differing sulphur component comprises treating said stream with an aqueous solution of an alkali metal hydroxide containing a substantial amount of a dissolved salt of a fatty acid or phenol under conditions whereby said mercaptans are absorbed in the alkali metal hydroxide solution to form mercaptides, and two layers are formed, one comprising the aqueous solution of an alkali metal hydroxide containing salt and mercaptides and the other consisting of treated hydrocarbon oil, separating said layers, further treating said hydrocarbon stream by intimately and vigorously mixing said acid with said stream, conducting the acid-hydrocarbon mixture into a settling zone, allowing said mixture to remain in said settling zone for a period of time sufficient to bring about formation of reaction products of remaining sulphur components, which reaction products dissolve in the acid, further aiding said reaction and settling by subjecting the mixture to an electrical field which is generated by a direct current of approximately 2000 to 10,000 volts per inch of electrode spacing with the electrode spacing being between 2 and 12 inches, whereby completion of said reaction is ensured as well as rapid coalescence of acid droplets to separate said acid from the treated hydrocarbon, and separating the acid and the desulphurized hydrocarbon stream from the electrical field and from one another. A further electrostatic field may be employed in the mixing and settling zones. The preferred salt is sodium or potassium isobutyrate; many other acids and phenols are listed. Following the treatment with sulphuric acid and the electrostatic precipitation, the oil may be neutralized with caustic alkali. The mixture of oil and caustic alkali may be separated by further electrostatic precipitation. In an example, the feedstock was a naphtha.

Abstract: 1,138,378. Polymer compositions. EASTMAN KODAK CO. 4 Nov., 1966 [5 Nov., 1965], No. 49513/66. Heading C3P. Polymer compositions are prepared by polymerizing an olefin monomer in the presence of excess monomer under superatmospheric pressure and at sufficient temperatures to render the polymer highly fluid and admixed with substantial proportions of monomer, passing the polymer into a reduced pressure zone whereby rapid gasification of the monomer occurs so as strongly to agitate the polymer, and simultaneously with the gasification and agitation, introducing solid, particulate material into the zone whereby the particulate material becomes intimately blended with the polymer. Specified monomers are C 2-10  α-olefins, particularly ethylene, which may be polymerized in the presence of oxygen, peroxides, methoxymethyl hyponitrite or mixtures of tetraethyl tetrazine and lauroyl peroxide. The process may be effected batchwise or continuously. The additive may be a slip or antiblocking agents, and may be introduced in the form of a dispersion in a carrier, e.g. waxes, low molecular weight polyethylenes and mineral oils. In examples ethylene is polymerized under pressure in a continuous process and the product mixed during pressure let-down with (1) silica in an amorphous polypropylene carrier, (2) silica, fatty acid amides and butylated hydroxytoluene in a microcrystalline wax carrier and (3) silica in a white mineral oil carrier. The compositions form non-blocking films.

Abstract: 1361597 Automatic speed control AGFAGEVAERT 19 Oct 1971 [23 Oct 1970] 50498/70 Heading G3R [Also in Division G4] The speed of a roller, which may be a backing roller in a dip coating system for photographic material, is regulated by timing successive pulses received by two fixed detectors from a member synchronized with the roller. In an example, a roller 70 is driven by a motor 71, and is connected to a disc 72 with alternate transparent and opaque regions at its periphery, Fig.4. The regions may be formed photographically or by cut-outs. The disc cooperates with a photo-head 73 including a light source and diaphragm 14 with slots aligned with two photo-transistors 12, 13. The outputs from the photo-transistors passes to a circuit 74, Fig. 9 (not shown), which uses an integrator to derive a value for the time elapsing between corresponding pulse signals from the two phototransistors. The inverse of this value is then computed by an operational amplifier circuit with a pulse width modulated input, Fig. 10 (not shown), and used as a measure of the roller speed for comparison with a set speed signal from a controller 76. The error signal produced is used to adjust the input to motor 71 to maintain the roller speed at the desired value.

In a process for the continuous finishing treatment of webs of textile material, e.g. poplin, at temperatures below 100‹C, for example for bleaching, dyeing with vat dyes, subsequent press treatment or high quality finishing, such as creaseproofing or waterproofing involving heat treatment with the exclusion of atmospheric oxygen, the web is continuously impregnated with a treatment agent and is passed into a heat-treatment chamber which is filled with a uniform mixture of steam and an inert gas, e.g. nitrogen, the proportions of the mixture being such that the particular saturation temperature of the partial pressure of the steam corresponds to the theoretical treatment temperature of the finishing process. A mixture of steam and inert gas is preferably supplied continuously to the heat-treatment chamber, the desired partial pressure of the steam being measured by controlling the content of the inert gas through measurement of the temperature of a wet-bulb thermometer in the vicinity of the point at which the web enters the chamber. A predetermined excess of the mixture of steam and inert gas may be conveyed in counterflow to the web of material over a heating zone at the end of the heat treatment chamber at which the impregnated web enters the chamber, the web being heated in the heating-up zone and the excess of the mixture of steam and inert gas leaving the heat-treatment chamber by way of a very narrow inlet slit so that the particular resistance to flow in the treatment chamber produces a slight excess pressure to prevent the uncontrolled ingress of air.
