Feed gas, free of CO 2 , enters the system via line 10, is passed through heat exchanger 12 and then to a separator 14 from which condensed water is removed via line 16. The gaseous phase is fed by line 18 to either of two driers 20, cooled in heat exchanger 24, and fed into a benzene scrub column 28 wherein the heavier hydrocarbons are condensed and removed via line 30. The feed gas stream passes from the column via line 34 to exchanger 36, is partially condensed, and fed to a separator 38; the liquid phase is used to supply reflux for column 28 whilst the gas is liquefied and subcooled in tube circuits 48 and 54 of a two zone heat exchanger 50, and stored. Exchangers 12, 24 and 36 are cooled by a single component refrigerant, such as propane or propylene supplied by compressors 60 and 62. The refrigerant is expanded at valve 66 into exchanger 12, vaporized refrigerant is returned to compressor 62 and liquid passed via lines 70, 72 and expansion valve 72 to exchanger 24. Any vapour produced is recycled to the compressor whilst the liquid is used in exchanger 36. The multicomponent refrigerant, consisting of nitrogen, propane, ethane and methane, is compressed at 100 and 102, and passed through heat exchangers 86 and 88 which are cooled by refrigerant liquid from exchanger 12 supplied via lines 70 and 90. The partly liquefied refrigerant is passed to a separator 110 and the liquid phase supplied via lines 112, 114 expansion valve 116, line 118 and spray header 52 to the zone exchanger 50.

Title: Improvements in fuel flow control circuits
IPC: F23Q1/06
Filed: 1968-11-18
Abstract: 1,216,687. Control circuit for burners. CONTROLS CO. OF AMERICA. 18 Nov., 1968 [28 Dec., 1967], No. 54532/68. Heading F4T. An ignition and fuel flow control circuit for burners comprises an igniter requiring a first operating voltage when no flame is present at the burner and a second, lower voltage in the presence of a flame, an electrically controlled fuel-flow valve arrangement requiring a first current to open it and a second, lower current to maintain it open, electrical control means such that the higher and lower voltages at the igniter produce, respectively, the higher and lower currents in the fuel-flow valve, and valve control means which reacts to the continued presence of the higher current in the valve by closing the valve, thereby interrupting fuel flow. As shown, the voltage pulses for arcing electrodes 10, 12 are supplied by a circuit containing capacitor 24, resistors 26, 28, silicon controlled rectifier 20 and primary 18 of transformer 16. Before ignition occurs, the higher voltage required to produce a spark results in a correspondingly high voltage at base 38 of transistor 34 and this base voltage, controllable by rheostat 44, allows sufficient current to flow through the transistor to open the fuel-flow valve which is operated by solenoid 32. In the presence of a flame at the burner, the required sparking voltage is lower, and the resulting lower current through the transistor is sufficient to maintain open the fuelflow valve. If the fuel fails to ignite, the continued higher current raises the temperature of heater 52, thereby causing thermally responsive switch 54 to open, and the resulting open circuit causes the fuel-flow valve to close. The lower current flowing when the burner is ignited is insufficient to open the circuit in this way. In another embodiment, solenoid 32 is replaced by a solenoid 56 (Fig. 2, not shown) wrapped around the closure element of a fuel valve. The valve is maintained open by the lower current, but in the event of ignition failure the resulting higher current increases the temperature in a heater (64) causing expansion of a bimetal which pushes the valve closure element back into its orifice, thereby shutting off the fuel flow. In a further embodiment, Fig. 3, thermal switch 72 is normally closed, so that as soon as the circuit is powered, the valve controlled by solenoid 68 is opened, whereas the valve controlled by solenoid 66, which is in series with valve 68, is only opened by the higher pre-ignition voltage. However, if ignition does not occur, the continued higher voltage causes a temperature rise in heater 70, resulting in the opening of thermal switch 72, thereby closing the valve operated by solenoid 68.

Title: A process for the production of organic esters
IPC: B01J23/40
Filed: 1967-12-01
Abstract: 1,216,499. Unsaturated organic esters. FARBENFABRIKEN BAYER A.G. 1 Dec., 1967 [17 Dec., 1966], No. 54851/67. Heading C2C. In a process for the production of unsaturated esters by reaction of an olefin or alkyl benzene, oxygen and an organic acid at elevated temperature in the presence of a catalyst containing elementary Ru, Rh, Pd, Os, Ir or Pt, the catalyst is prepared by reducing a compound of the metal with a hydrocarbon at an elevated temperature. Reactions are preferably carried out in the gas phase at temperatures within the range 50‹ to 350‹ C. Supported palladium catalysts are preferred, and the palladium compounds may be converted into the oxide before reduction. The catalysts are regenerated by heating in the presence of oxygen and reducing the resulting oxide with a hydrocarbon. Silver or gold and an alkali metal salt may also be included in the catalyst. Examples describe the production of vinyl acetate using catalysts comprising palladium supported on a lithium/aluminium spinel and including sodium acetate, and palladium supported on silica and including gold and potassium acetate.
