Abstract: A process for polymerizing ethylene in a high-pressure polymerization system having a continuously operated polymerization reactor and a reactor blow down system having an emergency valve, a reactor blow down vessel containing an aqueous medium and a reactor blow down dump vessel, wherein the process includes the steps of monitoring the polymerization system for a disturbance, opening the emergency valve when a disturbance occurs to allow the content of the polymerization system to expand into the reactor blow down vessel, contacting the content of the polymerization system in the reactor blow down vessel with the aqueous medium to obtain an aqueous polymer slurry, separating the polymer slurry and gaseous components, and transferring the polymer slurry to the reactor blow down dump vessel.

Abstract: The process and apparatus according to the invention allow the production of chemical compounds without the use of catalysts. For this purpose, the reactants necessary for the desired products are fed to compression reactors. In addition, the reaction conditions are controlled by means of an electronic control device. For this purpose, among other things, the compression reactors are combined with an electric motor, thereby influencing the residence time in the reactors. In addition, it is planned to raise the reactant pressures with the help of a compressor. In addition, the operating conditions are recorded with suitable sensors and/or analysers.

Abstract: A system for treatment of a biomass material, said system comprising: a first vessel (3) in which said biomass material is treated under a first pressure; a second vessel (5) in which said biomass material is received and held at a second pressure which is lower than the first pressure; a transporting pipe (7) connecting an outlet (9) of the first vessel (3) with an inlet (11) of the second vessel (5) for transporting the biomass material from the first vessel to the second vessel; and a valve (15; 15′; 15) arranged in said transporting pipe (7), said valve being configured for controlling the flow of biomass material and fluid in the transporting pipe (7), wherein said transporting pipe (7) is asymmetrically connected to an outlet (33′; 33) of said valve (15; 15′; 15) such that a generated jet stream of biomass material delivered out from the outlet (33′; 33) of the valve (15; 15′; 15) is received closer to a transporting pipe longitudinal central axis (A1) than if the outlet (33′; 33) of the valve (15; 15′; 15) and the transporting pipe (7) would have been connected symmetrically.

Abstract: A method for preparing supercritical fluid by deep-sea pressure is provided and belongs to the technical field of supercritical fluid preparation. The method includes the following steps of: placing low-pressure fluid in a closed flexible container, sending the closed flexible container down to a location of a sea at a depth where a seawater pressure meets a requirement by using a powered or unpowered traction device, leaving the flexible container standing still until a volume of the flexible container does not change, wrapping the closed flexible container with a rigid pressure-bearing container, transferring the closed flexible container to the sea surface by the powered or unpowered traction device, and taking out the fluid in the flexible container as supercritical fluid. Then the supercritical fluid is produced. Therefore, the process of preparing supercritical (high pressure) liquid in deep-sea is safer and more stable than the preparation way on land.

Abstract: Technologies are presented for reducing corrosion M supercritical water gasification through seeded sacrificial metal particles. The metal panicles 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: A pressure vessel has a restraint structure for accommodating thermal cycling thereof, including: a body with a cylindrical section; a skirt connected to the body and having a foot; and a plurality of blocks disposed around the skirt adjacent to the foot. Each block: is anchored to a support frame or foundation, and has a base and a flange. Each flange overlaps the foot, thereby vertically linking the blocks and the skirt. A radial clearance is formed between an outer surface of the foot and an inner surface of each base. A vertical clearance is formed between an upper surface of the foot and a lower surface of each flange.
