Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the more dense liquid of the mixture behind. An incomplete separation is witnessed during the separation of two immiscible liquids.
Reaction product separation device and separation method
PendingCN122076047AOrganic compound preparationDistillation regulation/controlDistillationIndustrial scale
The invention discloses a reaction product separation device and a separation method. The reaction product separation device comprises a circulating tower, a pressure pump, a cooler, a water removal tank, a dehydration tower, a feeding pump and a product tower which are connected in sequence, the product tower is connected with the circulating tower; the circulating tower is also connected with the raw material water separation tank; by adopting an operation method of coupling decantation non-sharp separation rectification and variable pressure crushing azeotropy, the separation device can be used for continuously separating reaction products of a process for preparing methyl acrylate from methyl acetate-formaldehyde in industry, and is simple in process, small in equipment number, simple and convenient to operate and suitable for industrial large-scale separation.

PROCESS FOR THE REMOVAL OF IMPURITIES FROM HARD WATER AND THE FORMULATION IT EMPLOYS
The present invention consists of a process for removing impurities from hard water. Using chemical agents, it removes impurities by mixing a chemical preparation and employing decantation in the first stage of impurity removal. Subsequent validation of the results allows for the removal of other types of impurities present in the water, such as arsenic, cadmium, cyanide, copper, chromium, mercury, nickel, lead, and zinc. Finally, it removes contaminants and microorganisms from the following group: fats and oils, suspended solids, organic carbon, total nitrogen, total phosphorus, worm eggs, E. coli, and fecal enterococci. The resulting sediments are used as biofertilizers, and the treated water can be discharged into conventional municipal sewer systems or, if necessary, treated with ozone (O3) for human consumption.
