A system and a method for separating water and salt by sequential evaporation of multiple groups of heat collecting devices. The system comprises heat collectors, a light-gathering heat collector, a heating chamber, an evaporation chamber, a condenser, a buffer chamber and a vacuum pump; a saline water stock solution is rapidly heated by multiple series-connected-multiple groups of parallel solar heat collecting devices and series-connected light-gathering heat collectors with decreasing water levels, and the water levels control water inlet and the temperature controls water outlet; several groups are started up in turn to perform micro-negative pressure evaporation, while other groups provide phase change heat energy, and the buffer chamber collects concentrated saline water; natural convection heat exchange occurs between the saline water stock solution and a vapor manifold, vapor heat energy is recovered and condensed fresh water is produced.

The present invention relates to evaporation apparatus (100) comprising manifolds provided with at least one nozzle (102), a tank unit (103) for a liquid, and a sample holder configured to be inserted into the tank unit. The sample holder is configured to hold at least sample in a defined position relative the at least one nozzle a control unit (104) an inlet port (105) configured to be connected to a gas supply, a pressure regulator (106) arranged downstream the inlet port (105). A set value of the pressure regulator (106) is controlled by the control unit (104), a control valve (107) arranged downstream the pressure regulator (106), wherein each of the at least one manifold (101a-d) is connected to a corresponding output port of the control valve. The control valve is controlled by the control unit (104), and the control unit is configured to set the set value of the pressure regulator to a value that causes a predetermined gas flow from each of the at least one nozzle.

The invention relates to a rotary evaporator (1) which is designed for the automatic execution of decompression steps during an overall process, in particular during distillation. With the decompression steps (III) to (VI), a complete removal of residual portions of condensed distillate at the inlet connection (71) of the intermediate valve (7) and in the condenser (5) of the rotary evaporator (1) can be accomplished. The rotary evaporator (1) has an electronic control module (9) which is designed and programmed to automatically carry out the decompression steps and other process steps with the rotary evaporator (1).

Systems, apparatuses, and methods for cleaning brine solution are provided. In particular, one or more embodiments comprise a brine cleaning system that includes a brine cooker, a brine filter, and a brine storage unit. The brine cooker heats a dirty brine solution to separate the dirty brine solution into a liquid portion and a solids portion. The brine filter is coupled to the brine cooker to receive the liquid portion and the solids portion from the brine cooker and then substantially remove the solids portion. The brine storage unit is coupled to the brine filter to accumulate the liquid portion once the solids portion have been substantially removed by the brine filter. This allows for more efficient and environmentally friendly use of brine solution in the curing of animal.

The present disclosure relates a system for the treatment of water. The water treatment system may be linked an aquatic protection system or a water filtration system.

The present application relates to a method for removing an unreacted vinyl chloride monomer (VCM) in polyvinyl chloride (PVC). According to an illustrative stripping apparatus and a stripping method using the stripping apparatus of the present application, in a stripping process using steam, a temperature difference between a raw material including a target substance to be removed and steam is minimized to suppress foam generation in the stripping process, thereby increasing efficiency of removing the target substance to be removed, particularly, an unreacted VCM in PVC. In addition, a cleansing cycle to remove foams generated in the stripping apparatus can be reduced, thereby not only securing economic feasibility of the process, but also preventing degradation in quality of a final product that may occur when an antifoamer to remove the foams is used.
