摘要： The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

摘要： The present invention discloses an integrated composite overload injection system and a working method thereof. The feeding mechanism preliminarily mixes water with a main agent and an auxiliary agent of an intelligent energy-gathered oil-displacing agent according to the ratio, the outlet of the feeding mechanism is communicated with the input port of the composite overload mechanism through a pipeline, the composite overload mechanism stirs, mixes, dissolves and overload ripens the preliminarily mixed solution to form mother solution, the mother solution is input from the output port of the composite overload mechanism to the inlet of the booster pump through a pipeline, the booster pump injects the boosted mother solution into the mixer, the mixer mixes the mother solution and the diluted high-pressure water and injects it into an oil-water well, and the power shafts of the composite overload mechanism and the booster pump are both driven by the driving mechanism.

摘要： The invention relates to a method for manufacturing a liquid acid concentrate for hemodialysis machines, with the following steps. In a preliminary step a water source (120), an acid source (130), an electrolyte tank (140) containing a mixture of electrolytes in exactly the quantity needed for the manufacture of the liquid acid concentrate, and a sodium chloride source (150) are connected to a mixing tank (110). During Step a), the quantity of water needed for the manufacture of the batch of liquid acid concentrate is introduced into the mixing tank (110). At Step b), the quantity of acid needed for manufacture the liquid acid concentrate is introduced into the mixing tank (110), the solution is stirred until a homogeneous solution is obtained. Step c) is to repeat Sub-steps c1) and c2) until the electrolyte mixture contained in the electrolyte tank is completely dissolved. At Sub-step c1) part of the solution contained in the mixing tank (110) is transferred into the electrolyte tank (140) containing the electrolyte mixture, then at Sub-step c2) the solution contained in the electrolyte tank (140) is transferred into the mixing tank, leaving the still solid constituents in the electrolyte tank. At Step d) the quantity of sodium chloride needed to manufacture the liquid acid concentrate is introduced into the mixing tank (110). Finally, at Step e), the solution is stirred and recirculated by taking it from the bottom the mixing tank (110) and reintroducing it at the top of the mixing tank until a homogeneous liquid acid concentrate is obtained. Steps a) to d) can be performed in any order, Step a) preceding always Step c).

摘要： An apparatus for accelerated dissolution of carbonates with buffered pH. The apparatus includes a mixer, a dissolution reactor and a pH correction reactor. The mixer includes: a chamber; a water supply; a carbonic gas supply; and a carbonate supply. Water, carbonic gas and carbonate are provided to the chamber in predetermined continuous flow rates to obtain a design flow rate of lean mixture at the outlet. The dissolution reactor includes a duct connected to the chamber receiving the lean mixture and allowing at least partial dissolution of the carbonate which transforms the lean mixture into an ionic mixture according to the reaction CaCO3+CO2+H2O□ Ca(HCO3)2. The pH correction reactor comprises a duct and a hydroxide supply. The mixture is then released into the sea. Embodiments also relate to a method for the accelerated dissolution of carbonates with buffered pH for the permanent sequestration of CO2 in the sea in the form of bicarbonates.

摘要： There is provided a gas solution supply apparatus capable of preventing bubbles from being generated in use at a point-of-use even if gas solution to be provided to a point-of-use has a high concentration. The gas solution supply apparatus 1 includes: a gas dissolving unit 4 that dissolves a source gas in a source liquid to produce a first gas solution; a first gas-liquid separator 10 that stores the first gas solution produced and produces a second gas solution through gas-liquid separation of the first gas solution; a pressure reducer 17 that depressurizes the second gas solution produced in the first gas-liquid separator 10; and a second gas-liquid separator 12 that stores the depressurized second gas solution and produces a third gas solution through gas-liquid separation of the second gas solution. The third gas solution is supplied to a point-of-use.
