Method of separating olefin oligomerization products using an evaporator
A recently granted patent (Publication Number: US11912658B2) discloses a method for separating olefin oligomerization products. The method involves several steps, including discharging a reaction mass from an oligomerization reactor, contacting the reaction mass with a catalyst system deactivating agent, isolating fractions, directing parts of the reaction product stream into a separation column and an evaporator, and separating the fractions to obtain the target a-olefin and other by-products. The method is particularly characterized by the use of ethylene as the initial olefin and the trimerization of ethylene in the oligomerization reactor.
Furthermore, the method involves specific temperature and pressure ranges for carrying out the separation process, with the evaporator being a thin-film evaporator or a rotary film evaporator. The method also includes steps for isolating the target a-olefin and other fractions, such as hexene-1, from the reaction product stream. The patent claims cover various aspects of the method, including the specific fractions obtained, the equipment used, and the conditions under which the separation process is carried out. Overall, the method provides a detailed and systematic approach to separating olefin oligomerization products, with a focus on obtaining the target a-olefin efficiently and effectively.
