Embodiment 1

[0036] According to the accompanying drawings 1 and 2, the toluene disproportionation micro-reactor has been set up to run smoothly for more than two years. Even if the microcomputer breaks down (or shuts down the microcomputer), it will not affect the normal production of the device except that the data recording and some alarms are affected; if a certain intelligent instrument is damaged or does not work normally, the system can detect and alarm in time, and can be replaced in time .

Abstract

This invention relates to toluene dismutation micro automatic control system, which solves the problem for not weighting and metering pump data bus through dynamic data exchange technique and for not sending tested data to relative database program for second process. This invention comprises micro computer, temperature control measurement, pressure measurement, flow control measurement and weighting measurement part.

Description

technical field [0001] The invention relates to a toluene disproportionation micro-reaction automatic control system. Background technique [0002] Toluene disproportionation microreactor is an important evaluation method for toluene disproportionation to xylene catalyst. Improving the level of automation as much as possible and reducing the labor intensity of operators are the main ideas in the design of this set of equipment. Document Chinese patent 01126968.5 introduces a reaction method and device for xylene isomerization and toluene disproportionation. This document discloses the process equipment required for the reaction, but does not relate to the control system. Document Chinese patent 00119767.3 introduces a method for disproportionation of toluene and transalkylation of heavy aromatic hydrocarbons. This document mainly solves the problems in the previous literature that the utilization rate of heavy aromatics in the aromatics complex is not high, the yield of C...
