Abstract: A liquid-vapor separating drum has a screen dryer mounted in the upper portion between the primary separators and the vapor outlet. The screen dryer is constructed and mounted in such a way that only minimal access is required in the space above the screen dryer whereby the space can be minimized. A central pair of dryer rows is installed first when there is easy access. The two outside rows are then merely clipped in place which does not require any access. The bottoms of the rows are joined by drain panels which form a flow barrier and which serve to collect the liquid extracted by the screens. Hanging rods are used to support these drain panels and thereby indirectly support the bottoms of the rows. Vortex breakers in drain apertures of the drain panels improve the drainage rate.
