Description

technical field

[0001] The invention belongs to the technical field of the aromatic hydrocarbon industry, and in particular relates to a process method for improving the low-temperature heat utilization efficiency of an aromatic hydrocarbon device and a low-temperature heat utilization system of the aromatic hydrocarbon device. Background technique

[0002] The aromatics unit is one of the core raw material units in the chemical fiber industry. It uses straight-run, hydrocracked naphtha or ethylene pyrolysis gasoline as raw materials to produce at least one aromatic hydrocarbon in benzene, p-xylene, m-xylene and ortho-xylene product.

[0003] A lot of low-grade heat energy in aromatics plants cannot be utilized. Therefore, low-temperature heat utilization in aromatics plants has become an important means of energy saving and consumption reduction in aromatics plants. At present, the low-temperature heat generated by the aromatics plant is mostly used to generate hot water o...
