  • Patent number: 4904347
    Abstract: A liquid product (4) leaving a furnace (2) is introduced into a series of cyclone separators (5, 6, 7). The liquid product to be vaporized is introduced tangentially into the top portion (5a, 6a, 7a) of each cyclone to place the product into contact with a side wall (5b, 6b, 7b) of the cyclone. A gaseous phase (11, 12, 13) formed in each cyclone is collected in the central zone (8, 9, 10) of the cyclone and is then introduced into a vacuum distillation column (3). The liquid phase obtained in each cyclone is collected at the bottom (5c, 6c, 7c) of the cyclone and then is introduced tangentially into the top (6a, 7a) of the following cyclone or, in the case of the last cyclone, is introduced directly into the vacuum distillation column (3). The side wall (5b, 6b, 7b) of each cyclone (5, 6, 7) is heated to a temperature near the maximum temperature allowable for avoiding all thermal deterioration of the product.

  • Patent number: 4777607
    Abstract: The electronic interface device permits remote control and monitoring of a power distribution panelboard coupled with a management system. In respect of each outgoing power line, a local control unit is connected to a remote control unit while a central unit is assigned to each local control unit to the remote control unit which then converts the data delivered by the local control unit into data which are compatible with the central unit. Exchange of data between each remote control unit and the management system is achieved by at least one microprocessor-based control circuit located in the central unit, through a series link or current loop.

  • Patent number: 4577093
    Abstract: The high-power electric heating device is capable of heating gas mixtures such as a mixture of hydrocarbons and hydrogen to temperatures and pressures attaining C. and 60 bar respectively. A central duct connects the gas mixture inlet to the outlet and is constituted by a plurality of superposed independently removable modules. Each module comprises a plurality of electric resistance elements formed by banks of adjacent metallic strips. A peripheral zone of the device contains power supply conductors connected to the modules. By means of passages in the form of slits between the central duct and the peripheral zone, a small fraction of the gas stream is permitted to flow within the peripheral zone.

  • Patent number: 4514245
    Abstract: According to the method of the invention there is wound, around a hollow body (1) and in substantially contiguous turns, a flexible strip (2), the latter strip being fixed onto the hollow body. The strip is of a material, the tensile limit of which is in excess of that of the material of which the hollow body (1) is made, and when wound around the hollow body, a tension is applied thereto which is sufficient for the stresses which may develop within the body and the winding of the strip (2) to reach their permissible maximum limits at substantially the same time, when the hollow body is used under pressure.

    Abstract: A method for heating crude oil to be processed in a petrochemical installation, comprises successive heat exchangers disposed in series, each heat exchanger using pressurized steam as the heating fluid. Each exchanger has a lower exchange chamber, a liquid product supply line and a tube bundle, the steam transferring heat to liquid product flowing through the tube bundle. Each heat exchanger comprises an upper separation chamber disposed above the lower exchange chamber, the separation chamber having a gas phase outlet and a liquid phase outlet, the liquid phase outlet being disposed lower than the level at which the tube bundle extends into the separation chamber. Successive heat exchangers are connected together by a pipe communicating between the liquid phase outlet of the upper separation chamber of one of the heat exchangers and the liquid product supply line of the next heat exchanger.

  • Patent number: 4149092
    Abstract: Emitters and rotary hydraulic displacement pumps are associated with one or a number of propeller-type transducers and connected to receivers each having a rotary hydraulic displacement motor coupled to an alternator. The emitters are connected to the receivers by means of a hydraulic circuit for an auxiliary fluid which is admitted into at least one shunt-connected energy dissipator and the flow of which is regulated as a function of the random energy variations of the natural fluid. The energy-conversion system is primarily applicable to hydroelectric power plants of the stream or river type, to wind-driven power plants and to ship propulsion.

  • Patent number: 3968030
    Abstract: In a chemical processing plant such as a petroleum refinery, provision is made for steam boilers and heating furnaces in which the energy consumed by the boilers for generating steam exceeds the energy consumed by the heating furnaces. The steam is produced at a pressure level which is sufficient to operate at least one back-pressure turbo-alternator, then to heat the chemical process stream to a sufficiently high temperature by heat exchange with the steam recovered at the outlet of the turbo-alternator.
