We are supplier and manufacturer dividing wall columns (DWC). Benefits of Dividing Wall Column 1.Solved the problem of the organization of the fluid flow on the tray. 2.The liquid overflow takes place in the vertical plane without using any specific overflow devices (internal distribution); 3.The uniform arrangement of liquid on the trays; 4.We use any geometric configuration of the trays (segment of a circle, triangle, square, cross-section of the torus).
