Title: Petrol prodn
IPC: C10L1/02
Filed: 1969-09-24
Abstract: Petrol of high octane number and lower reactivity and volatility is prepared by a process in which the first stream of exit gases from the cracker (B.Pt. range -10 degrees to +77 degrees C) consisting predominantly of C4-6 tertiary alkenes, is contacted with a lower alcohol e.g. methanol or ethanol, in the presence of an etherifying catalyst e.g. a sulphonated polystyrene resinous material, to convert most of the alkenes to ethers. The ethers stream is then combined with at least one stream containing hydrocarbons boiling in the range -10 degrees C to + 219 degrees C to give a low volatile petrol. Octane numbers for the C5 alkene fraction of 97.3 are increased to 100.8 after etherification.

Title: Methanol synthesis with improved reboiler heating
IPC: C07C29/151
Filed: 1971-04-02
Abstract: In a catalytic MeOH synthesis where a fluid hydrocarbon is steam reformed to give a high temp. synthesis gas stream (g.s.), this g.s. is cooled in a steam boiler to an intermediate temp. by a first heat exchange (h.e.) with water, and then cooled further to condense the water. The resulting g.s. is compressed and combined with a recycle g.s. to form a synthesis feed g.s. This is heated by a third h.e., passed to a catalytic MeOH-synthesis at elevated temp., and press. cooled by the third h.e. and further cooled by a fourth h.e. to condense the MeOH. The crude MeOH is separated at elevated press. The residual gas is divided into a purge g.s. and the recycle g.s. The MeOH is distilled under reduced press. in distillation columns fitted with lower reboilers. These reboilers are heated by cooling the intermediate temp. g.s. by passing through at least one, passing a liquid through the fourth h.e. which is heated and passed through a second reboiler, and recycling the cooled liquid.

Title: Refrigeration system for drying compressed gas - has expansion valve parallel with main one controlled by separate detector for partial loads
IPC: F25B41/04
Filed: 1976-04-08
Abstract: The refrigeration system has a closed coolant circuit with pump, condenser, expansion valve and vapouriser exchanging heat with the commodity to be refrigerated. The expansion valve is controlled by a temp detector in contact with the coolant downstream of the vapouriser. Means are included for keeping press in the vapouriser to a constant value, and for preventing liquid coolant from penetrating into the pump. There is a second small expansion valve (11) connected in parallel to the first one (6), these together being capable of supplying the quantity of coolant required by the vapouriser at full load. A second detector (12) to control the second valve is mounted downstream of the first one (9). Thus at smaller loads the temp peak in the coolant corresponding to the reaction threshold of the detectors occurs downstream of the first one, so that the second valve operates, under control of the second detector.

Title: Flag waving control system - uses hollow mast with air blowing venturi apertures at top facing flag, and connected by pipe to pressure source
IPC: E04H12/32
Filed: 1979-04-11
Abstract: The installation is for the control of flags used on official, sports and festive occasions, so as to ensure that they are waving fully when required. A hollow flag mast is used inside which is a pressure pipe. At the top end of the mast, the pipe evolves into a number of branches ending in venturi-type outflow apertures. By adjustment of the dia. of these apertures the outflow speed of the emerging air is balanced, and the holes themselves are located on opposite sides of the flag hoisting rope.
