Separation equipment for Fischer-Tropsch slurry bed reactor products

Abstract

The invention discloses separation equipment for Fischer-Tropsch slurry bed reactor products. The separation equipment comprises a casing and a cyclone separator unit, wherein the casing comprises a casing inner cavity, and a mixed solution feed port is formed in the side wall of the casing; the cyclone separator unit comprises a plurality of cyclone separators, feed ports of the cyclone separators are used for receiving the Fischer-Tropsch slurry reactor products input from the mixed solution feed port, and a gas-phase component outlet and a liquid-phase component outlet are formed in the topand the bottom of each cyclone separator respectively; a gas discharge port is formed in the top of the casing; an area, located below the liquid-phase component outlets of the cyclone separators, inthe casing inner cavity is a liquid-phase component accommodating area; an impurity discharge port is formed in the bottom of the casing; a liquid-phase discharge port is formed in the position, corresponding to the liquid-phase component accommodating area, of the side wall of the casing. According to the separation equipment and technology, gas-phase, liquid-phase and solid-phase separation ofslurry bed reaction is realized, internal parts of the separators are prevented from being blocked by the solid-phase particles, and filter products meet the following system production demands.

Description

technical field [0001] The invention relates to the technical field of chemical material separation, in particular to a Fischer-Tropsch reaction gas-liquid mixture separation device. Background technique [0002] Slurry bed reactors are widely used in the fields of coal chemical industry and petrochemical industry. Fischer-Tropsch synthesis reactions use slurry bed reactors. However, in slurry bed reactors, fine catalyst particles, liquid reactants and products Mixing together will cause the problem that the reaction product and the catalyst are difficult to separate. Therefore, how to effectively separate the catalyst fine powder particles and the reaction product is one of the key technologies in the slurry bed process. [0003] In the slurry bed reaction process, with the progress of the reaction, the catalyst is worn and broken. The broken catalyst needs to be discharged out of the reactor along with the slurry through regular discharge, and at the same time, fresh catal...

Problems solved by technology

However, when the reaction product is discharged from the top of the Fischer-Tropsch reactor, it will carry part of the catalyst fine powder and flow out of the reactor at the same time. The catalyst fine powder will cause the gas-liquid phase separation effect in the product to deteriorate. If the reaction product cannot be effectively separated, the catalyst The metal substances in the slurry will directly affect the product quality. Therefore, how to realize the effective separation of the reaction products is an urgent problem to be solved in the slurry bed reaction.

At present, in the existing published technical literature, there is no technical solution to effectively deal with this problem
