Abstract: The present invention discloses a pump-type autoclave system and a providing method for steam and pressure thereof, wherein the pump-type autoclave system comprises an autoclave, a steam providing device and a compressor, said steam providing device comprises a water storage container and a heating device used for heating said water storage container, said water storage container, the compressor and the autoclave are connected through a pipeline to form a closed loop, an inlet of the compressor is connected with a steam output port of the water storage container, an outlet of the compressor is connected to a steam input port of the autoclave, and a condensate water drain outlet of the autoclave is connected to the water storage container. The present invention uses the compressor to depressurize an intermediate-low temperature water source to obtain steam, and the steam is pumped into the autoclave and condensed to release heat to obtain corresponding temperature and pressure. Since the present invention fully utilizes a great amount of low-cost intermediate-low temperature heat sources obtained from natural, industrial or living waste heat to provide needed high temperature, steam and pressure to the autoclave system, the energy is saved.

Abstract: A mixing reactor for precipitating nanoparticles by mixing a precursor fluid with a second fluid at a higher temperature than the precursor fluid. The reactor comprises: a first fluid conduit with an inlet region configured to receive a flow of the precursor fluid, and an outlet region configured to output a mixed flow; and a second fluid conduit configured to receive a flow of the second fluid. The second fluid conduit extends into the first fluid conduit in a direction substantially perpendicular to the flow within the first fluid conduit, and has an opening for introducing the second fluid into the first fluid conduit. Related processes for producing nanoparticles are disclosed.

Abstract: The present invention provides an automated experiment apparatus and an automated experiment method using the same for putting a sample into a pressure vessel and automatically performing a chemical and/or physical reaction of the sample under a predetermined temperature and pressure. According to the embodiments of the present disclosure, it is possible to automatically perform an experiment from the beginning to the end without intervention of an user. As a result, it is possible to prevent a risk of gas leakage and human exposure to a harmful gas due to a manual operation. The apparatus comprises a controller which is configured to automatically perform a reaction process under a predetermined temperature and pressure in a state in which a sample holding member is air-tightly fixed to a pressure vessel and the sample is accommodated in a sample receiving chamber of the pressure vessel.

Abstract: Large-scale manufacturing of gallium nitride boules using m-plane or wedge-shaped seed crystals can be accomplished using ammonothermal growth methods. Large-area single crystal seed plates are suspended in a rack, placed in a large diameter autoclave or internally-heated high pressure apparatus along with ammonia and a mineralizer, and crystals are grown ammonothermally. The orientation of the m-plane or wedge-shaped seed crystals are chosen to provide efficient utilization of the seed plates and of the volume inside the autoclave or high pressure apparatus.

Abstract: The present invention relates to a method and an arrangement for pressure and temperature let down of autoclave discharge slurry, in particular in pressure oxidation or high pressure acid leach of metal containing ore. The method of the invention comprises a step of providing autoclave vent gas obtained from the autoclave to the top-entry flash vessel for inducing overpressure to the top-entry flash vessel and preventing boiling of the slurry during the transfer to next top-entry flash vessel. The invention further relates to an autoclave and pressure let-down arrangement adapted for providing autoclave vent gas to one or more top-entry flash vessels.
