Spherical high pressure multiple phase reactor

Abstract

The spherical high-pressure multiple phase reactor is one chemical apparatus for gas-liquid or gas-liquid-solid slurry reaction. The reactor consists of two or more spherical reactors connected serially. It has gas distributor fixed in the bottom of the lower spherical container, separating baffles supported inside the spherical container, and laminated inner members fixed inside the separating baffles for realizing the homogeneous phase distribution of the gas phase in different spherical parts of different cross section areas to promote the homogeneous distribution and raised contact efficiency of different phases. The inner members have functions of guiding flow, re-distributing and inhibiting bubble growth. Compared with cylindrical reactor, the present invention has one half reduced wall thickness, easy construction and reduced investment, and is suitable for large high pressure reaction process.

Description

technical field [0001] The invention belongs to the scope of chemical equipment, in particular to a spherical high-pressure multiphase reactor. Background technique [0002] Chemical and petrochemical processes involve a large number of high-pressure multiphase reaction processes, such as petroleum hydrocracking, methanol synthesis, Fischer-Tropsch synthesis, dimethyl ether synthesis and other energy-related industrial processes. These processes are related to the national energy strategy. Feasibility depends on the scale of production. If it is necessary to build a single device with a production capacity of hundreds of thousands of tons of reactors, due to the requirements of high-pressure processes and industrial scale-up, the traditional cylindrical reactors face design difficulties. At present, the more advanced reactors in these industrial processes generally adopt the gas-liquid-solid three-phase slurry operating system. The slurry bed reactor has the characteristics...

AI Technical Summary

Problems solved by technology

At present, the more advanced reactors in these industrial processes generally adopt the gas-liquid-solid three-phase slurry operating system. The slurry bed reactor has the characteristics of excellent heat transfer performance, but the mass transfer efficiency between phases is relatively low, resulting in industrially designed reactions. The volume of the reactor is relatively large, and to achieve economically profitable large-scale design, the volume of the reactor will also be larger

The high-pressure operation of the system has very strict requirements on the wall thickness and material selection of the reactor, especially for large-scale high-pressure reactors such as cylindrical vessels with a diameter of about 10 meters.
