Title: Vacuum distn. of liquids without external heat - partic. useful for desalination of sea-water
IPC: C02F1/04
Filed: 1974-03-25
Abstract: In a process for vacuum distn. without using external heat, the distilland and the distillate are under vacuum at temperatures which are equal or slightly different. The satd. vapour from the distilland is partly compressed to displace the vapour-liquid equilibrium toward the formation of liq. The heat of condensn. is exchanges with the heat of evapn. The compressor is a vaned turbine or pump or a Rootes type compressor and the heat transfer is carried out in exchangers of the fluid circulation type. The temperatures of the distilland and the distillate are kept uniform by mechanical agitation. The process is partic. useful for distilling sea water. It uses considerably less energy than distillations in which heat is supplied to raise the temp. to the boiling point and to vaporise the liquid, and energy is used to condense the vapour.

Title: Process and installation for vehicle remote control - uses magnetic field to control on horizontal plane
IPC: G05D1/02
Filed: 1974-12-20

Title: Dehydrogenation of satd. hydrocarbons - in a fluidised bed of catalyst from which catalyst is drawn off, regenerated and recycled
Inventor: JUGUIN BERNARD
IPC: C07C5/333
Filed: 1975-05-07
Abstract: The process is effected using at least one moving catalyst bed, at 300-600 degrees C, 0.1-20 bar, and with an LHSV of 0.1-30 and an H2/feed molar ratio of 0.1-30. The catalyst flows downwards through the reaction zone and is progressively withdrawn from the bottom and passed to a regenerator.

Used esp. for converting 3-40C n-paraffins into olefins for use in the prodn. of biodegradable alkylaromatic sulphonate or sulphate detergents or for use as OXO process feeds. Use of the moving beds avoids the loss of catalyst activity and selectivity associated with fixed-bed operations.
