Investigation of material cost of an ethane-ethylene rectification column
Kulcsszavak:reflux ratio, material cost, ethane-ethylene rectification column
In this study with the tray-by-tray method an ethane-ethylene rectification column was studied. Therefore, the effect of reflux ratio on the material cost of ethane-ethylene rectification column was investigated. In case of the modification of reflux ratio the diameter of the column and the number of trays will modify. Not only these parameters, but also the required wall thickness for strength was determined. In case of the investigated column between the reflux ratio and the diameter of the column there is second degree polynomial relationship. There is a minimum point of the material cost function, which belongs to the optimal reflux ratio.
