Devices and methods for the high-pressure treatment of bulk material by extraction and/or impregnation. The bulk material is arranged in the interior volume of a pressure vessel device and is treated at a high pressure while sealed off from the surroundings. The high-pressure treatment is performed batchwise in a closed system in the pressure vessel device in a pressure-tight fashion. The bulk material is fed batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level and, after the high-pressure treatment has occurred, being discharged batchwise from the interior volume with the pressure vessel device closed. The invention furthermore relates to the use of a supporting tray module with at least one treatment level for the high-pressure treatment in a closed system.

Two inline tower gas wet scrubbers having a moving bed of solids for scrubbing exhaust gas

Two inline tower gas wet scrubbers wherein each scrubber has a moving bed of solids 0010 that is conveyed from the top to the bottom of the towers via a plurality of perforated moving floors 003 arranged one above the other. Wherein the moving floors are mounted on plenums 004 that extend from the internal walls of the towers. A liquid 008 is sprayed from the top of each tower, wherein the liquid washes the exhaust gas, capturing particle matter and absorbing acidic gases and heat. As the liquid falls under gravity, the liquid is filtered through the solids. Exhaust gas e.g. containing CO.sub.2 enters the first scrubber 001 above the bottom plenum and travels upwards over the moving bed towards the outlet at the top of the scrubber, whilst being washed by the falling liquid. The warm carbonated solids and liquid that exit the first reactor are fed into the top of the second reactor 002, whilst the gas exiting the first reactor enters the second reactor via the plenums/ducts that support the moving floors thereby distributing the gas throughout the reactor.

The present invention relates to a process for the polymerization of olefin monomers in the presence of a catalyst system, using a tubular pre-polymerization reactor, wherein the tubular pre-polymerization reactor has a length L and the flow of a catalyst system is introduced in the tubular pre-polymerization reactor in the middle (30-70% of L) or the end (70-95% of L) of the tubular pre-polymerization reactor.

A method of heat-treating a waste cathode material to recover lithium carbonate from the waste cathode material, and a lithium carbonate recovery method using the waste cathode material heat treatment method are provided. The method of heat-treating the waste cathode material includes heating an interior of a heat treatment furnace by burning a hydrocarbon fluid in the heat treatment furnace and producing lithium carbonate (Li.sub.2CO.sub.3) and residual metal oxide by reacting a waste cathode material in the heat treatment furnace with CO.sub.2 generated during burning of the hydrocarbon fluid.

A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.
