Systems and methods for operating a water recovery system are disclosed and include activating a condenser of the water recovery system. The method includes measuring a temperature associated with the condenser based on data obtained from a condenser temperature sensor. The method includes comparing the temperature associated with the condenser to a maximum threshold temperature. The method includes activating an auxiliary condenser of the water recovery system in response to the temperature associated with the condenser being greater than the maximum threshold temperature.

A process that produces a non-alcohol cereal beverage (NACB) includes separating an input fermented malt beverage (FMB) into an output FMB and the NACB, wherein the separating includes multiple stages; and adding water during the separating so that the output FMB has the same alcohol by volume (ABV) as the input FMB during each stage of the separating.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid. The fluid vapor distillation apparatus also includes a control system.

A purification system can provide for efficient heating of liquid via film heating, which, rather than heating a large volume of liquid, can heat a thin layer of liquid thus reducing the amount of energy required to evaporate the liquid. Film heating can enable evaporation of liquids using less energy than other methods. In addition, when liquids (e.g., seawater) having dissolved solids (e.g., salts) are heated, both the liquid and the solids must be heated. As evaporation occurs, the concentration of solids increases and more energy must be supplied to the liquid in order to cause evaporation. Because purification system can heat only a layer of liquid, less energy is required to heat the solids, which can allow for higher energy efficiencies in purifying liquids. These efficiencies can lead to decreased cost of potable water. Related apparatus, systems, techniques, and articles are also described.

The invention relates to a cleaning device for separating an organic isocyanate produced by the reaction of an organic amine with a stoichiometric excess of phosgene in the gas phase from the gaseous raw product obtained in the reaction, said device comprising a first separating body comprising at least one raw product supply line for a gaseous raw product flow containing at least the isocyanate, hydrogen chloride and non-reacted phosgene, a first liquid supply line for a liquid flow containing at least one quench liquid, and a first liquid discharge line for a liquid flow containing at least part of the quench liquid and part of the isocyanate, a first gas line for transporting a gas flow containing at least hydrogen chloride, evaporated quench liquid and phosgene leading away from the first separating body. The invention is characterized in that at least one addition body for directly introducing at least one cooling fluid for an at least partial condensation and/or absorption of the gas flow that can be guided via the first gas line is associated with the first gas line.

In an improved method of distilling fluids, some or all of the fluid is recovered as distillate and the fluid is situated in the shell side of a first shell and tube heat exchanger. The fluid to be recovered as distillate is successively boiled, demisted, compressed and then introduced into upper ends of the tubes. A second shell and tube heat exchanger is located below the first heat exchanger, and distillate from upper ends of the tubes in the second heat exchanger are arranged to receive distillate liquid and/or vapor from the lower ends of tubes of the first heat exchanger. The fluid is located in the shell of the second heat exchanger and that fluid is heated but is not boiled. A mechanism is provided to supply at least some of the heated fluid to the shell of the first heat exchanger.

The present invention generally relates to a system for treating effluent water. More particularly, it provides a robust apparatus for treating waste liquid by optimizing solar and wind energy to maximize the evaporation rate as compare to natural evaporation rate. The main object of the present invention is to provide a system for evaporating RO reject and other effluent liquid and other liquids, by optimizing system to solar and wind energy to maximize vaporization rate and recovery rate at marginal operational cost.

An electronically or mechanically controlled system is devised, such that the outlet control system in a flow path delivers a desired flow rate of pre-mixed ratio and quantity of gases based on inlet and outlet pressure conditions. The desired flow rate from the system/device does not depend on type of gas/fluid being mixed such that system will always deliver a mixed gas and also do a real-time measurement of actual flow of the mixture.

A wastewater collection tank feeds a vaporizing unit through an inlet near the unit's top. A burner produces heat, which a blower blows through a blower tube that passes through the upper portion of the unit to the bottom portion of the unit. A substrate through which heated air can pass extends across the unit between the bottom of the blower tube and the wastewater inlet, and pall rings rest on the substrate. The heated air moving upward through the unit heats the pall rings and the falling wastewater, a substantial portion of which is vaporized at approximately atmospheric pressure. The vapor is vented from the top of the unit. Un-vaporized wastewater collects at the bottom of the unit and is recycled through the system with raw wastewater in the collection tank.
