摘要： The invention relates to a method of and an apparatus for fluidised bed regeneration of a catalyst containing coke.The catalyst and some of the regeneration fumes are drawn off from the dense bed of a regenerator (1) and are introduced by gravity into an external exchanger at a junction point below the level of the dense bed of the regenerator. Heat exchange is carried out in the lower part of the exchanger (7) below the junction point. From the bottom end of the exchanger up to above the junction point a dense bed zone is created the level of which is established substantially at the height of the dense bed in the regenerator and a zone (15) of suitable size for the escape of regeneration gases and fluidisation gas. The gases and fumes are drawn off into the dilute fluidised phase (18) of the regenerator through a duct (17) while the catalyst is recycled to the dense bed of the regenerator through a different duct (25) from that in which the fluidisation air is circulating.Application to the regeneration of fluid bed cracking catalysts.

摘要： A method and device for producing effluent contained in a submarine geological formation which enables a submarine transfer of a petroleum output over short and medium distances between, for example, a hydrocarbon deposit and a hydrocarbon processing platform located over a larger deposit developed previously. At least one wellhead of the wells in the geological formation is connected to a production line feeding into the processing platform, with a pumping module being provided in the form of a jet pump connecting the wellheads to the production line whereby the hydrocarbons are pumped from the outlets of the well heads to the processing zone by the jet pump.

摘要： A device for positioning a tool or instrument in a duct and recovering the tool or instrument therefrom by causing a vector fluid to flow through the device. The device includes a tubular element adapted to be connected to the tool or instrument and an annular sealing arrangement mounted on the tubular element for sealing the tubular element in the duct. The tubular element includes an arrangement for selecting a direction of movement of the tool or instrument which includes a closing device for cooperating with a resilient conjugate piece and a device for reversing a direction of movement of the closing device. The cooperation of the closing device with the resilient conjugate piece occurs in at least three states. In the first state, the fluid flows through the tubular element in a first direction; in the second state, the fluid flow is stopped in a direction opposite to the first direction of fluid flow; and, in the third state, the fluid is stopped in the first direction. The reversal device is adapted for holding the closure device either in the first and second state while excluding the third state, or in the third state.
