Filed: 2002-10-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a distillation column which is used in a chemical plant, e.g. an ethylene plant, and inhibits the generation of a polymerizate therein.  <P>SOLUTION: In the column 1, shelves 10 are installed at a suitable interval. A steam-mixed feed (a) after naphtha pyrolysis is fed from a decomposition furnace into the lower part of the column 1. From its upper part, a distilled component (b) is sent out to a quenching tower, and from the lower part, a fuel oil (c) is discharged. At a suitable hole 14a of a tray 14 of a shelf 10, a guide 16 for causing steam to flow along the peripheral wall of the tower is set and prevents a liquid from staying in the vicinity of the peripheral wall. A steam flow is caused also over the tray face of a beam 13 to inhibit the liquid from staying on the upper surface, making polymerization due to staying hardly possible. For example, the guide 16 comprises the peripheral wall 17 surrounding the periphery of the hole 14a of the tray 14 and a lid wall 18 blocking the upper side of the peripheral wall 17, this wall 17 having an opening 19 formed therein so as to look toward a staying section.  <P>COPYRIGHT: (C)2004,JPO
