Title: Integrated controlled freeze zone (CFZ) tower and dividing wall (DWC) for enhanced hydrocarbon recovery
Inventor: SINGH VIKRAM
IPC: B01D3/14
Filed: 2007-11-20
Abstract: The present invention relates to methods and apparatuses for the operation of a distillation tower containing a controlled freezing zone and at least one distillation section. The process and tower design are utilized for the additional recovery of hydrocarbons from an acid gas. In this process, a separation process is utilized in which a multi-component feedstream is introduced into an apparatus that operates under solids forming conditions for at least one of the feedstream components. The freezable component, although typically CO2, H2S, or another acid gas, can be any component that has the potential for forming solids in the separation system. A dividing wall is added to at least a portion of the lower distillation section of the apparatus to effect the separation of at least some fraction of the hydrocarbons in that portion of the tower.

Abstract: 418,979. Electric speedometers. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. April 4, 1933, No. 10083. Convention date, April 5, 1932. [Class 106 (iii).] A disc or vane forming the indicating member is rotated against a spring control by a magnetic field energized by polyphase current supplied from a generator driven by a member, the speed of which is to be observed. The generator, Figs. 1, 4 and 5, includes a rotor driven by multiplying gear 16 from the spindle 17 and consisting of a non-magnetic block 19 carrying bar magnets 22 and I-shaped compensators 34 made of metal the permeability of which varies with temperature differently from the magnet steel. Polyphase current, the frequency of which is proportional to the speed, is generated in stationary field windings 26 connected by three wires 13 to the indicator instrument 12, shown also in Figs. 8 and 10. A non-conducting casing 38 with a metal magnetic shield 39 encloses a pair of substantially rectangular laminated cores 44, 44<a> carrying windings 45 supplied with the polyphase current, the windings being energized to the saturation point to eliminate the effect of change of voltage so that the indicator is responsive to frequency only. A thin disc 49 preferably of aluminium is mounted within gaps 47, 48 in the core on a spindle 50 carrying a pointer 56 the magnetic drag being opposed by a hair spring 54<a>. The movements of the disc are damped by a permanent horse shoe magnet 58. The disc rotates between the poles of the magnet and the keeper 59. To compensate for permeability changes in the cores 44, 44<a> resulting from temperature changes, magnetic shunts 61 are supported by spacing sleeves 62 across the gaps of the magnetic circuit. Coils 63 of fine wire may be wound on the compensators.

Abstract: 541,029. Valve generating circuits. CALVERT, R. June 14, 1940, No. 10395. [Class 40 (v)] A crystal controlled oscillator has a crystal connected in a feed-back circuit between the cathode of a cathode follower and the grid. In Fig. 3 the triode V1 is arranged as a cathode follower by the provision of resistance R1. A controlling crystal K is connected to the grid of V1, through amplifiers V2, V3 the function of which is to make up the voltage loss in the crystal and valve VI, without introducing substantial phase shift. In Fig. 4 to prevent intermodulation of harmonics produced by the limiting action of the circuit, an A.V.C. is supplied by applying the output from V3 to an amplifier V4 and diode V5 which applies an A.V.C. potential to V2. V4 acts as a separator valve and the output of the oscillator is taken from O, E. The phase lag due to V2, V3 may be corrected by a condenser connected across resistance R5 and the frequency may be adjusted by condensers C1, C2.

Title: Aminodiazaboranes and their preparation
Inventor: BROWN MICHAEL PETER
IPC: C07F5/02
Filed: 1962-03-20
Abstract: The invention comprises aminoboranes having one or other of the formulae <FORM:0975841/C1/1> <FORM:0975841/C1/2> and <FORM:0975841/C1/3> wherein R is an alkyl group of 1-8 carbon atoms, R1 is an alkyl group of 1-5 carbon atoms, R11 is an alkyl group of 1-5 carbon atoms, and n is 2 or 3. Specified aminoboranes are 2-dimethylamino-1,3-dimethyl-1,3,2-diazaborinane; N,N1-dimethyl-N,N1-bis (1, 3-dimethyl-1, 3, 2-diazaborinyl)-trimethylenediamine; 2-dimethylamino-1, 3-diisopropyl-1, 3, 2-diazaborolidine, N,N1-diisopropyl-N,N1-bis (1, 3-diisopropyl-1, 3, 2-diazaborolo) ethylenediamine; 2-dimethylamino-1, 3-di-t-butyl-1, 3, 2-diazaborolidine.  The aminoboranes may be made by the transamination of a tris (dialkylamino) borane in which the alkyl groups contain 1-5 carbon atoms by heating to a temperature of 100-210 DEG C. in the absence of water and free oxygen, with a disecondary ethylenediamine or trimethylenediamine in which the nitrogen atoms each carry an alkyl group of 1-8 carbon atoms.  The reaction may take place in an atmosphere of a dry inert gas, e.g. dry nitrogen or argon.  If substantially equimolar proportions are used the main product is I; if the diamine is in excess, formation of II is favoured, with III as an intermediate.  A compound of type I is also favoured by cooling the reactants at an early stage to interrupt the process, and also by use of a bulky, e.g. secondary or tertiary alkyl, or cyclic, group R. The presence of a catalyst will favour type II, a suitable catalyst being an amine salt of a strong acid, which may be made in situ from hydrogen chloride or sulphuric acid. Detailed examples are given. The compounds are useful as additives to leaded motor fuels and lubricating oils.
