Apparatus for preparing oligomers

Abstract

The present invention relates to an apparatus for preparing an oligomer, and more particularly, to an apparatus for preparing an oligomer, comprising: a reactor comprising a gas region provided at the lower part with a first gas reactant inlet, and a reaction region comprising a reaction medium in contact with a gas reactant above the gas region; a second gas reactant inlet and a third gas reactant inlet, the second gas reactant inlet being disposed on the inner wall of the reactor in the gas region, the third gas reactant inlet being disposed on the inner wall of the reactor facing the second gas reactant inlet; the first injection nozzle is connected with the second gas reactant inlet, and the second injection nozzle is connected with the third gas reactant inlet.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2020-0121969 filed on September 22, 2020, the entire contents of which are incorporated herein as a part of this specification. technical field [0003] The present invention relates to an apparatus for preparing oligomers, and more particularly, to an apparatus for preparing oligomers, which makes the process unstable by making the process unstable in a short time when a dripping phenomenon occurs in the reactor. Minimize variability and ensure stable run times without shutting down process operation. Background technique [0004] Alpha-olefins are important materials used in comonomers, detergents, lubricants, plasticizers, etc., and are widely used commercially. Among them, 1-hexene and 1-octene have been widely used as comonomers for adjusting the density of polyethylene in the preparation of linear low densi...

AI Technical Summary

Problems solved by technology

However, at the initial stabilization stage where mixing is performed, a problem occurs that, in addition to the expected oligomer according to the reaction, the dispersion flow of the gaseous reactant is hindered by polymer, which is a by-product generated in the catalytic reaction, or due to Momentary reduction in the supply flow of gaseous reactants due to operator error when operating the flow control device

[0008] Therefore, dripping occurs, which is a phenomenon in which a part of the liquid reaction medium in the reaction zone falls into the gas zone in the lower part of the reactor, in this case, the liquid reaction medium falling into the gas zone blocks the gaseous reactants inlet, thereby continuously obstructing the injection and flow of gas

As a result, the mixing efficiency in the reaction zone is significantly reduced, leading to problems shutting down the entire process run
