Abstract:
The invention is directed to a process for carrying out a chemical reaction in an ionic liquid as solvent and CO2 as cosolvent, in which process reactants are reacted in a homogeneous phase at selected pressure and temperature to generate a reaction product at least containing an end-product of the reaction, and upon completion of the reaction a multiphase system is obtained by change of conditions, wherein at least one of the phases is the ionic liquid and at least one other phase is a carbon dioxide phase at least containing the end-product, which carbon dioxide phase is substantially free of ionic liquid, separating the carbon and recovering the end-product.
Abstract:
A spring-containing device comprises a housing including a removable end plate (2). A plurality of screw-threaded tie rods (7) have nuts (10) holding the end plate (2) in assembly with the housing. A safety plate (13) is disposed within the housing against the end plate (2) and clear of a movable spring-retaining plate (8) at its closest approach to the end plate (2). The safety plate (13) is fast on a shaft (15) rotatable in the end plate (2) and adapted (at 18) to be turned from outside. The safety plate (13) has recesses (15) in its peripheral edge (14) through which recesses (15) respective tie rods (7) can pass. The tie rods (7) have recesses (19) which can receive the unrelieved edge (14) of the safety plate (13) when in a certain angular position and thus prevent longitudinal relative movement between the safety plate (13) and the tie rods (7).
Abstract:
Technologies are presented for reducing corrosion in supercritical water gasification through seeded sacrificial metal particles. The metal particles may be seeded into one or more material input streams through high pressure injection. Once distributed in the SCWG reactor, the metal particles may corrode preferentially to the metal SCWG reactor walls and convert into metal oxides that precipitate out above the supercritical point of water. The precipitated metal oxides may then be collected downstream of the SCWG reactor to be reprocessed back into seed metal at a smelter. The seeded metal particles may complete a process material cycle with limited net additional waste.
Abstract:
The present invention relates to a vacuum chamber in which metallic vapours are deposited, said vacuum chamber comprising at least one reflector and a tube, where a first end of said tube is arranged inside said vacuum chamber and provided for receiving electromagnetic radiation, a second end of said tube is extending inside said vacuum chamber and a central axis of said tube is slanted with respect to a surface of a substrate surface which is generating metallic vapour. Said reflector is arranged inside said vacuum chamber to reflect electromagnetic radiation which is exiting from said second end of said tube onto said substrate surface which is generating metallic vapour.
Abstract:
The invention relates to a method for debindering and/or purifying granules or material suitable for use in High Pressure High Temperatures diamond or cubic boron nitride synthesis, the method comprising the steps of passing the granules or material through a zone having controlled atmosphere and temperature in a continuous manner, the zone having a maximum temperature within the zone of greater than approximately 600°C, wherein the time spent by each granule within the zone is less than 30 minutes.
Abstract:
A control system of a surgery autoclave is described, which is capable of establishing a sterilisation cycle which comprises at least a first evacuation step of a sterilisation chamber and of heating of a load and a final drying step. The autoclave comprises a device capable of detecting a parameter proportional to the energy used up in a step of the cycle preceding the drying step and the control system establishes at least a reduction of said drying step upon determining that, the parameter of used up energy lies below a preset threshold.
Abstract:
The invention relates to devices for carrying out chemical processes in a gas-liquid medium and can be used, in particular in reactors for synthesising carbamide from ammoniac and carbon dioxide at high temperatures and pressures. The internal structural design of a reactor comprises contact units whose ends are fixed to a supporting array and each of which consists of vertically lowerable and liftable tubular elements which are connected to each other by an U-shaped tubular element having the same diameter. Said contact units are arranged above the supporting array. The liftable element is provided with an opening embodied in the supporting array for a liquid and gas input. The end of the lowerable element is sealed with a plug and is provided with output holes for the gas-liquid mixture embodied on the side surface on the lower part thereof. Said invention ensures the flowrate stability, provides with a developed phase contact surface, reduces the hydraulic resistance of the contact units and increases the efficiency of a reaction process.
Abstract:
A reaction vessel (1) for conducting a reaction involving one or more reactants. The reaction vessel comprises a pressure resistant outer vessel (2), said outer vessel having an inner wall, and a liner (3) which is removable contained within the outer vessel and which lines the inner wall of the outer vessel and thereby avoids contact between the inner wall of the outer vessel and the one or more reactants. A space is present between the outer vessel and the liner. The liner is chemically inert and resistant to the one or more reactants to be contained inside the liner and the liner has at least one opening in communication with the inside of the liner. The reaction vessel further comprises a sealing means (5) arranged near the opening (4) of the liner and sealing the space between the outer vessel and the liner from the inside of the liner at least as the pressure difference across the sealing means is below a threshold pressure difference.
Abstract:
An autoclave for sterilising packed fluid products, in particular baby food products, comprises a boiler (1), having two access doors (3, 4) that can be hermetically sealed, and a sterilisation vessel (2), arranged such that it is able to rotate inside the boiler, and means for rotating the sterilisation vessel. A conveyor is arranged in the sterilisation vessel. During rotation cages containing filled packs which have been introduced via the conveyor are pressed onto the conveyor by means of pneumatic or hydraulic pressure means (11). Compressed air or hydraulic medium can be fed to the pressure means (11) and removed therefrom via a connector (17). The connector (17) is fitted at the end of a swinging arm (12), which by means of a control means (27, 28) is able to swing between an operating position in line with the axis of rotation of the sterilisation vessel (2) and a position in which the connector (17) does not block the access of the cages (9) to the sterilisation vessel.
Abstract:
A multi-channel fluid dispenser includes a reservoir (106) with multiple internal chambers (844) with ports (850) to fill each chamber (844), a multi-channel liquid dispensing head, a plurality of fluid-delivery conduits, and support and positioning elements.
