Multitubular slurry bed reactor and reaction system

Abstract

The invention relates to a tubular slurry bed reactor and a reaction system. The tubular slurry bed reactor is a reactor for producing ethylene from high-concentration acetylene, which includes an inlet section, a tubular distribution section and an expansion section arranged in sequence, and also includes an upper section connected to the tubular distribution section Connecting area with the lower section of tubes, wherein, the gas inlet section is provided with a gas inlet for passing the reaction gas into the tube-and-tube slurry bed reactor; the tube distribution section is provided with a plurality of tubes for the reaction The gas reacts in the distribution section of the tubes to produce ethylene. Multiple tubes are provided with an upper tube communication area and a lower tube communication area. Filters are installed at both ends of the upper tube communication area, and the top of the expansion section is set. There is a gas outlet. The design of the tube-tube communication area in the tube-tube slurry bed reactor of the present invention can ensure that the liquid level in each tube is uniform and avoid gas short circuit, and the setting of the filter in the upper section of the communication area can ensure the replacement of the solvent and regeneration.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to the field of preparing ethylene by using high-concentration acetylene, in particular to a tubular slurry bed reactor and a reaction system using the slurry bed reactor. Background technique [0002] Ethylene is an important basic raw material in modern industry and one of the world's largest output chemicals. Its products are widely used in national economy, people's life, national defense and other fields. It is the "mother of organic synthesis". Facing the shortage of oil resources and rising international oil prices, the source of raw materials has become a bottleneck in the development of the ethylene industry, and it is also a problem that must be solved before people. Therefore, the research and development of a new source and process method to prepare ethylene to replace petroleum as a new process and new technology can alleviate the dependence on petroleum.

AI Technical Summary

Problems solved by technology

However, when the traditional slurry bed reactor produces ethylene from acetylene, the gas-liquid-solid three-phase mixing is uneven, the contact time of the reaction raw materials is short, and the temperature of the bed layer in the reactor is uniform, and the temperature is not easy to control.
