[Also in Division G6] Carbon dioxide which is used as a coolant in a graphite-moderated nuclear reactor and to which a small proportion of methane has been added to inhibit corrosion of the graphite, is purified by converting the water content to H 2  by reaction with CO, eliminating H 2  by diffusion, and oxidizing CO to C0 2  with oxygen. The reaction between H 2 O and CO may employ a Cu-Zn catalyst, and the oxidation of CO to C0 2  a Pt, Pd, Cu, or copper oxide catalyst. Diffusion of the H 2  takes place through tubes made of Pd alloy into another circuit containing C0 2  in which the H 2  is catalytically oxidized to H 2 0 which is removed by condensation. Reference, has been directed by the Comptroller to Specification 1,108,512.

Abstract: 1434379 Alkylating isoparaffins TEXACO DEVELOPMENT CORP 19 Dec 1973 [17 Jan 1973] 58869/73 Heading C5E [Also in Division G3] In an alkylation unit in which olefin and isoparaffin is contacted at 4 with acid (e.g. sulphuric) which is then separated in a settler 12 from the hydrocarbon product, which includes alkylate, the acid being recycled via 16, 20, 21, 7, the hydrocarbon content of the recycled acid is kept at a desired value by controlling the flow rate of fresh acid and/or the discharge of acid at 26 in response to the difference between the interface level in the settler and a reference value, the desired value for the hydrocarbon content being automatically determined in response to measurements of characteristics and flow of the olefins-isoparaffin input, the fresh acid, the recycle acid and the actual hydrocarbon content and to a calculation of economic values related to octane rating of the alkylate and to the cost of fresh acid. The object is to maximize the earnings of the unit. The system periodically postulates a step increase or a step decrease in the hydrocarbon content of the recycled acid and the resulting effect on the earnings is calculated at 130, 130A for each case, using measurements of olefin content of the input and its flow (from devices 55, 60 and 40), the flow of acid discharged (from 26), the flow of acid supplied to the contactor 7 (from 40A), the alkylate content of the output (from 55A, 105) and its flow (from 40B), and the present hydrocarbon content of the recycled acid, calculated at 45 from measurements of the density of the recycle acid, the fresh acid and the hydrocarbon product (at 43, 43A and 43B respectively). Constants for the prices are added within the computers 130, 130A. The computers determine whether a step increase, or decrease, or no change would be most desirable and passes a signal to means 251, 270 for adjusting the reference for interface level in settler 12. Limit circuits are provided so that no change is made if a step change would result in upper or lower limiting values for the hydrocarbon content of the acid being exceeded. As shown, the flow of acid discharged is kept constant by a closed loop 24, 25, 26 and the interface level is kept at the reference value by controlling the addition of fresh acid, by loop 30, 34, 36. The calculations are made periodically under the control of a programmer 58. Details of analogue versions of the computers are given in terms of assemblages of logic elements and it is stated that a general purpose digital computer could be used instead.

Title: Hydrogen Compression by Centrifugal Compressors
Inventor: JACKSON STEVEN B
IPC: C10G47/00
Filed: 1967-12-28
Abstract: 1,190,450. Hydrocracking; hydrodesulphurization. FLUOR CORP. Ltd. 28 Dec., 1967, No. 58966/67. Heading C5E. [Also in Division F1] The hydrogen compression of a gaseous stream comprising a predominant proportion by volume of hydrogen is increased by adding to the stream, prior to compression, hydrocarbon in the 30 to 80 molecular weight range so that the stream contains about 1% to 12% by volume of the hydrocarbon, and compressing the stream by passage through a multi-stage centrifugal conpressor, the added hydrocarbon acting to increase the hydrogen compression above the level otherwise attainable under the same operating conditions but in the absence of the added hydrocarbon. An oil feed, such as gas oil in the boiling range of diesel oil needing reduction in sulphur content or increase in cetane number, is introduced through a line 10 and pumped through a heater 11 to a hydrocracking or hydrotreating unit comprising one or more reactors 13, where it is converted at high pressure (500 to 4000 lb. per square inch) and temperatures of 500 to 900 F., the hydrogen required for the conversion being compressed to the high pressure in a multi-stage centrifugal compressor 15. After conversion, the resultant liquid and gaseous, or entirely gaseous mixture is cooled in a heat exchanger 19 and an air cooler 20 and, after removal of excess hydrogen in a separator 21, passes to a fractionation stage 27, in which a fraction having an average molecular weight in the 30 to 80 range and desirably largely butane is produced. The product hydrocarbon leaves at 28, while separated butane or equivalent is taken via a line 29 to a contactor 31 in which it is added to hydrogen (which may be by-product hydrogen containing hydrocarbons in the range methane to butane) from a line 30. The resultant gaseous mixture, containing up to 12% by volume of butane or equivalent, is used as impure hydrogen input to the compressor 15. Because the butane or equivalent increases the density, the required compression is obtained with three stages instead of the six which would be required if pure hydrogen were used. Unvaporized material from the contactor 31 may be returned via line 32 to the fractionation stage 27. Surplus hydrogen is returned from the separator 21 via a compressor 23. Instead of being introduced into the cycle at a point upstream of the heater 11, the compressed hydrogen may be introduced via line 25 at, say, the suction side of the compressor 23.

As shown in Fig. 2, the web joining device comprises a carriage 20 mounting upper rollers 24 which guide the running web in a path 17 for processing in an "outside" mode. The carriage 20 also supports a driven roller 21 for accelerating a standby reel 14 up to the speed of the running web, a pasting roller 28 carried by arms 27 angularly movable by means of a pneumatic ram 33, and a cutter 30 carried by arms 29 angularly movable by means of a pneumatic ram 31. When the running reel 15 is almost exhausted the rams 31, 33 are actuated to effect the splicing operation. When the inside face of the web, as wound on the reel, has to be presented for processing then the cradle 10 carrying the reels 14, 15 is positioned so that the running reel 15 is located above the standby reel 14 and the running web passes over lower guide rollers 24 on the carriage 20. The roller 28 and cutter 30 are moved to the position required to effect the splice in this "inside" mode of operation by swinging the arms 27 downwardly and the arms 29 upwardly, and a driven roller 22 is provided to accelerate the standby reel 14 (Fig. 3, not shown).
