PROCESS FOR REMOVING DIOXANE FROM A COMPOSITION |
摘要 |
Apparatus and processes for removing dioxane from a composition, e.g., an ethoxylated fatty alcohol sulfate paste, utilize an evaporator having an inlet chamber and one or more heated channels. The process includes the step of heating the composition at a location upstream of the flow restriction to a temperature above the flashing temperature of water at a pressure of the channel inlet and applying a pressure to the heated composition to avoid such flashing. The process further includes the step of passing the pressurized, heated composition through the evaporator. The process can further include injecting a vapor into the channel. The purified, concentrated product can be diluted with water to a desired concentration. |
