Flash evaporation is a process in which saturated water at high pressure enters a relatively low-pressure vessel and becomes part of the saturated water vapor and saturated water at the pressure of the vessel due to a sudden drop in pressure. In the chemical production process, the flash column can realize the rough gas-liquid separation of materials. The flash column can be roughly separated before entering the atmospheric furnace, which can reduce the load of the atmospheric furnace.
Classification of Flash column: Hawach’s flash column has three main series as follows: StarFlash Series: This series only has silica gel columns. It can be divided into two categories: standard and advanced. The high-grade silica gel flash column has higher purity and better quality.
Flash Series: This series corresponds to silica gel construction and phase column, C18 (spherical import and irregular homemade), C4, C8, NH2, CN, HILIC, alumina, etc. They have all imported fillers, corresponding to the high-end market.
DepuFlash Series: This series corresponds to silica gel construction and phase columns, C18 (spherical and irregular), C8, NH2, CN, Phenyl, SAX, SCX, Diol. They are all domestic fillers, corresponding to the low-end market.
