Abstract

The invention discloses a dispersion plate for a purification tower, which comprises: a support plate; at least one first fluid pipe passing through the support plate; and a plurality of second fluid pipes arranged spaced apart from and surrounding the first fluid tube, wherein at least one of the second fluid tubes has a length greater than the length of the other second fluid tubes and less than or equal to the length of the first fluid tube The length of the fluid tube.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2017-0086529 filed with the Korean Intellectual Property Office on July 7, 2017, the entire contents of which are incorporated herein by reference. [0003] The invention relates to a dispersion plate, in particular to a dispersion plate used in a butadiene purification tower. Background technique [0004] Butadiene has been used as an intermediate in many petrochemical products such as synthetic rubber and electronic materials, and it is one of the most important base oils in the petrochemical market, and its demand and value are gradually increasing. [0005] Butadiene can be obtained by purifying butadiene in C4 mixtures. For purification, a first extraction system, a second extraction system and a purification system are included. [0006] Here, in the purification system, a process of removing impurities is perfo...
