A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

Described herein is a method and a system for dispersing particles in a fluid. The method includes stirring a fluid including particles in a stirring container using stirring means. During stirring the fluid is recirculated by continuously retrieving an amount of fluid from a retrieving position. Further, the particles are milled, where during each pass through the milling means a size of particles in the retrieved fluid is reduced. The retrieved fluid having passed through the milling means is continuously reintroduced into the stirring container at a reintroduction position. The reintroduced fluid is mixed with the fluid in the stirring container in a mixing region defined by the stirring means, and the retrieving position is determined such that the retrieved fluid includes particles with an average particle size differing from the average particle size of particles in the mixing region.

Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

A nanobubble nozzle includes a body; an inlet for receiving a liquid; an outlet for discharging the liquid with nanobubbles; a forward channel extending through the body from the inlet to the outlet for transmitting the liquid, the forward channel having a venturi throat; a return channel extending from the outlet to recirculate a portion of the liquid and mix it with a gas to form a two-phase mixture; and an inlet port connecting the return channel to the venturi throat. The liquid flow through the throat creates a suction drawing the two-phase mixture into the throat. A cross-sectional area of the forward channel decreases from the inlet to the throat and increases from the throat to the outlet so that an internal pressure lower than an external pressure outside the body and lower than a vapor pressure of the liquid flowing through the throat is provided at the throat.

With a method for heating in particular milk or milk foam, in which the milk or the milk/air mixture is conveyed through a passage opening and hot steam is conveyed through at least one steam line transversely into this passage opening. The passage opening and the at least one inlet opening opening transversely into the steam line, the steam pressure in this and the pressure and the pressure in the passage opening with flowing milk or milk/air mixture are so coordinated that the hot steam at the at least one transverse inlet opening condenses in the passage opening directly on contact with the milk or the milk/air mixture. Consequently the additional energy produced by the phase change from steam to condensate water is transmitted directly as heat to the heat in the milk or the milk/air mixture.

The present invention discloses a preparation process of food-grade potassium dihydrogen phosphate, wherein phosphoric acid prepared from wet-process phosphoric acid is used for the preparation of high-purity potassium dihydrogen phosphate.

In accordance with presently disclosed embodiments, systems and methods for efficiently handling dry additives to be mixed with bulk material in a blender are provided. The systems may include a support structure used to direct bulk material from one or more portable containers on the support structure to a first outlet location, and a combined metering/transferring system for directing dry additives from another portable container to a second outlet location. Specifically, the metering/transferring system may output a metered flow of dry additives to the blender mixer to be combined with bulk material that is released from the portable containers. The metering/transferring system may utilize a gravity feed outlet coupled to a metered screw or other conveying device to move the dry additive from the portable container to the second outlet location.

A respiratory therapy system can have a flow generator adapted to provide gases to a patient. A gas passageway can be located in-line with the flow generator. The gas passageway can have a first portion adapted to receive a first gas and a second portion adapted to receive a second gas. The gas passageway can have a static mixer downstream of the first and second portions.
