Investigation of material cost of an ethane-ethylene rectification column

Multidiszciplináris tudományok, 2022
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.

Investigation of material cost of a propane-propylene rectification column

Multidiszciplináris Tudományok
In this study a propane-propylene rectification column was investigated in terms of diameter of the column, number of trays, reflux ratio and the construction material costs of the column. During the calculations the reflux ratio was modified between 8 and 30. The chosen material of the column and trays was 1.4404 grade austenitic steel.

REALIZABILITY FIELD AND AUTOMATIC OPTIMIZATION OF BINARY RECTIFICATION COLUMN

IZVESTIYA VYSSHIKH UCHEBNYKH ZAVEDENIY KHIMIYA KHIMICHESKAYA TEKHNOLOGIYA, 2018
It was shown that the dependence of maximal productivity of binary rectification column on heat consumption taking into account the irreversibility of heat and mass transfer can be charaterized with two generalized parameters. The system of automatic supporting of column regime corresponding to its maximum productivety was proposed.
