The invention relates to an intelligent reaction system and process for strengthening benzene and ethylene to prepare ethylbenzene, comprising: an alkylation reaction unit, a vapor recovery unit, a sedimentation unit, a water washing unit, a rectification unit, a micro-interface generator and an intelligent control unit. The invention processes ethylene by adding a micro-interface generator, crushes the ethylene to form micron-sized bubbles, and mixes the ethylene micron-sized bubbles with benzene to form a gas-liquid emulsion, so as to increase the phase interface area of the gas-liquid two phases , improve the reaction efficiency of ethylene and benzene, improve the utilization rate of benzene, and reduce the production cost of ethylbenzene. Through the intelligent control unit, the staff can know the real-time situation of the various data returned by the intelligent sensing module at any time through the mobile device, and can Accurate control of the temperature and pressure in the entire reactor can be achieved by changing the preset values, further improving the reaction efficiency. |
