Abstract

The invention relates to the technical field of chemical industry, and specifically relates to an arene device with improved structure, and an arene technology. The device is provided with a tee joint between an isomerization charge pump outlet pipeline and an isomerization feeding / separation tank bottom heat exchange tube stream inlet, wherein the tee joint is connected with a reflux pump outlet pipeline through a pipeline. Tower reflux is realized by change of the device structure, meanwhile, the emergency repair time for the faulted pump is obtained, and the device can be in normal operation all the time without stopping; and surcharge and energy consumption caused by shut down are lowered, times of unscheduled shut down is reduced, energy consumption increased in the starting up and shutting down process is lowered, increase of downtime cost of enterprises is avoided, and sequentially, the enterprise revenue is increased.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an aromatic hydrocarbon device and process with improved structure. Background technique [0002] In the aromatics production process, the materials need to be heated to enter the next step, but making good use of mechanical equipment is a prerequisite for realizing material heating. However, when the equipment is in use, there will always be pump failures. In order to ensure the safe operation of the production device for a long time and reduce the failure rate of the equipment, two machine pumps are usually set up at the same position, one of which is the operating pump and the other is the standby pump. If when one operating pump fails, another standby pump that switches to the operating pump continues to work, and when the standby pump also fails, the device cannot operate normally and needs to be shut down for processing. Thereby affecting the whole process eff...
