Abstract
The present disclosure provides an apparatus for preparing oligomer including: a reactor; a gas-liquid separator; a solvent transfer line; a second transfer line; a first spray nozzle unit; and a second spray nozzle unit. The apparatus is capable of improving stability of the entire process by including a first spray nozzle unit and a second spray nozzle unit in a reactor and thus preventing by-products containing polymer substances such as C20+ from being entrained with a desired product during a reaction.
