Abstract: 1396940 Gas separation and sulphur production INSTITUT FRANCAIS DU PETROLE 22 Sept 1972 [27 Sept 1971] 44021/72 Heading C1A The removal of hydrogen sulphide from gases containing it in low concentration is effected by a method involving the intermediate production of an alkali metal hydroxide from a sulphide thereof by: (a) contacting an aqueous alkali metal sulphide solution (preferably sodium or potassium sulphide) with an ammonium salt of strong inorganic acid (suitably ammonium chloride or sulphate) or a strong organic acid of 2 to 20 carbon atoms, said strong acid having a pKa lower than 5, at such a temperature that hydrogen sulphide and ammonia evolve, and to obtain an aqueous solution of an alkali metal salt of the strong acid, (b) reacting the hydrogen sulphide and ammonia with a gas containing sulphur dioxide or with ammonium sulphite to obtain elemental sulphur and ammonia and water vapour, (c) subjecting the salt solution produced in step (a) to anion exchange to retain the anion of the strong acid in the anion exchange medium and to evolve a solution of alkali metal hydroxide, (d) periodically regenerating the anion exchange medium by treatment with ammonia from step (b) to evolve a solution of an ammonium salt of the strong acid, and using this solution in step (a). The aqueous solution of alkali metal sulphide may result from contacting a hydrogen sulphide-containing gas with an aqueous solution of an alkali metal hydroxide, suitably of 0À1 to 8 moles/l. concentration, while the aqueous solution of ammonium salt in step (a) may have a concentration of 0À5 to 5 moles/l. Stage (b) may be effected in a liquid phase containing a higher alcohol having from 8 to 20 carbon atoms per molecule, a polyol, a mono- or poly-alkylene glycol or an ether or ester of these compounds, and ammonia and water vapour produced in this step may be condensed to form an ammonia aqueous solution before being used in step (d). An example illustrates the application of the process to the removal of hydrogen sulphide from a residual refinery gas, using a 2M sodium hydroxide solution.

Title: Elevator Controls.

Filed: 1966-10-04
Abstract: 1,163,727. Lift control systems. RELIANCE ELECTRIC CO. 4 Oct., 1966 [8 Oct., 1965], No. 44202/66. Heading B8L. In a multi-car lift system, landing calls are stored in a memory while being assigned to the most available car, the call being cancelled in the memory when service has been provided, and the assignment being cancelled if predetermined conditions arise, in which case the call is retained in the memory and is re-assigned. Operation of any up or down call button 47 is retained in memory 31 and starts a single call finder selector 32 comprising a ring counter which stops when coincident with the call, which is thus " found ". This positioned information is passed to an allotter 33 in which the state of each car is received and the call is assigned to the " best " car (as described below), the call then being retained in the " demand register" 43 of that car until the call is served. Allocation of the call releases the apparatus to deal with the next call. The call is also retained in the call memory 31 until the call is served, and if this is not achieved within a time set by a timer 76 the call is re-allocated as if it were a new one. Calls are also re-allocated if a car becomes fully loaded or is unduly delayed, e.g. by doors held open. Car motion, door operation, and hall lanterns are controlled by a car logic circuit 42 in response to the demand register 43, and also to a command memory 44 which responds to car push-buttons. The system employs solid state logic devices, such as AND gates and the like, and is fully described for a four car, ten floor installation. Two forms of allotter are described. In one (Fig. 1a, not shown) the cars are considered sequentially, in the order of spacing of cars from the call, and allocation is made to the first car whose criteria fall within prescribed limits. If none do, the limits are released and the search repeated. If no suitable car is found after a third search the apparatus deals with the next call. In the alternative form (Fig. 1b not shown) the condition of all cars are considered simultaneously. Anologue voltages are developed which represent (i) distance of car from call, (ii) number of stops between current position and call, (iii) total number of stops, (iv) load on the car; any of these factors may be exceptionally weighted. The voltages are summed for each car and all are scanned and stored. At the completion of the scan an increasing ramp voltage is generated with which the car voltages are simultaneously compared; when the ramp voltage becomes equal to one of the car voltages (the lowest), that car is assigned the call. If all the car voltages are too high the cycle is repeated. The call finding and allotting process is by-passed if a car travelling in the right direction is already required to stop at the calling landing.

Abstract: 1,164,118. Controlling feed water supply. BABCOCK & WILCOX Ltd. 26 Oct., 1966 [29 Oct., 1965], No. 46001/65. Heading F4A. A forced flow steam generating plant includes a feed pump 10, economizer 1, evaporator 2, separator vessel 3 and superheaters 5, 6 and 7 connected in series. A recirculation line containing a recirculating pump 9 leads from the base of separator vessel 3 to the economizer inlet 1. During start up and under low load conditions, with switch contact 20A closed and contacts 20B and 20C opened, level responsive device 21 and level controller 22, act on valve 23 to control the liquid recirculation rate to maintain a minimum liquid level in separator vessel 3. The maximum desired opening of valve 23 is set by device 24 and compared with the signal from flow meter 12, the resulting signal being sent to controller 25, also to operate the valve. Should liquid level in separator vessel 3 rise too high, blow down controller 29 opens a blow down valve 30 to reduce it. Flow meter 13 detects the flow to the economizer inlet, made up of the recirculation flow and the feed flow, and its signal is compared with the desired value signal from device 27, the resultant signal actuating controller 26 to regulate the feed flow from pump 10, as determined by flow meter 11, to the desired value. At loads above 36: 5% full load, switch contacts 20B and 20C are closed, and contact 20A opened. Feed flow rate controller 26 is now actuated by flow meter 11 and the difference between the signal from flow meter 13 and the desired value signal from device 27 as before, and by the feed/steam flow ratio controller 40. This in turn may be varied by temperature-responsive device 35 at the outlet of superheater 6 to ensure that the water-steam transition zone does not extend downstream of superheater 6. If this device 35 is not sufficiently effective, device 36 may actuate blow down valve 30 to exhaust liquid from the system. If the feed flow to the economizer is insufficient for cooling purposes, it may be augmented by recirculation flow. The feed flow signal 11 is compared with a desired safe value signal 24, the resultant signal actuating controller 42 to suitably regulate recirculation control valve 23. Should this result in a separator water level falling below a minimum value, switch 20 is again activated to restore the low load mode of operation until a sufficient water level is obtained for the system to return to the full load control mode of operation. When no recirculation is occurring under full load control (once through boiler operation) switch contacts 32A are actuated to prevent the level control circuit having any effect.
