A horizontal drum or accumulator is a drum located in horizontal position with usually no internals. Horizontal vessels are used to collect the overhead product from a fractionating tower. The overhead product is condensed and is transmitted back to the fractionation tower from which the fraction came. This liquid is referred to as the reflux.

Type any number into the fields, the other field will be calculated automatically.

Horizontal Elliptical Vessel - Case-1 (DH < DW):

Case-1 (DH < DW). Change case to Case-2 (DH > DW)?

Height of Ellipse = DH
Width of Ellipse = DW
Inside Diameter = D = 2R = DH
Length (TT) = L
Height = h

Volume (V) of Cylinder between TT-TT =

\small \bold{\color{blue} \left [ \left ( \frac{D}{2} \right )^2 \arccos \left ( \frac{\frac{D}{2} \ - \ h}{\frac{D}{2}} \right ) \ - \ \left ( \frac{D}{2} \ - \ h \right ) \sqrt[2]{Dh \ - \ h^2} \right ] \left( \frac{D_H}{D_W} \right) L }

Enter the variable values in below input boxes. Negative value of a means concave bottom.

 Height of Ellipse (DH): unit Width of Ellipse (DW): unit Length (TT) (L) : unit Height (h) : unit Depth of Head (a) : unit

RESULTS. Negative value or NaN means imaginer vessel. Check again your input.
