Questions about the liquid separation tank
Thread Content
In my equipment for producing devices, there are vertical liquid separation tanks and horizontal liquid separation tanks. Could an expert please explain under what circumstances each type of tank should be used? Thank you

In a horizontal container, the direction of liquid movement is perpendicular to the direction of gravity, which facilitates sedimentation and separation, and ensures good stability of the liquid surface； However, it has a small gas-liquid separation space, occupies a large area, and is not convenient to install at a high elevation. Horizontal tanks are recommended for the tower top reflux tank, gasoline-kerosene washing and sedimentation tank, liquid intermediate buffer tank, and oil-water separation tank. Vertical containers have a large gas-liquid separation volume, which facilitates the continuous separation of the intermediate mixing layer; they require less space and can be easily installed at a high height ； However, its liquid surface stability is inferior to that of horizontal containers. Gas buffer tanks, gas washing tanks, gas liquid separation tanks, and diesel washing and sedimentation tanks are recommended to use this type of container.
2.1.3 When the amount of liquid is large and the residence time between high and low liquid levels is 6^-9 minutes, a horizontal gravity separator should be used. 2.1.4 When the amount of liquid is small, the liquid level height is not determined by the residence time, but is restricted by the minimum distance l00mm between various adjustment points; in such cases, a vertical gravity separator should be used.
