Problems solved by technology

Although the utilization efficiency of the coil is high, the consumption of steam and cooling water is large
It leads to the increase of coal consumption of non-renewable energy and the waste of heat taken away by cooling water, and the heated cooling water will also cause serious waste of water resources when it is cooled by air cooling

Abstract

The invention discloses a heat energy synergy method of a hydration reactor. The method is characterized by comprising the following steps: a cooling medium of the hydration reactor is changed into raw material cyclohexene (HE), the cyclohexene moves through an upper coil of the reactor, and water vapor or cooling water moves through a lower coil. The self reaction heat release of the material is used in the hydration reactor, the heat exchange of the coil in the hydration reactor is used for supplying heat energy for the raw material cyclohexene, and meanwhile, the amount of the cooling water consumed for cooling the hydration reactor is reduced, the aims of utilizing the resource and saving energy and reducing consumption are achieved. The method is used for directly supplying heat energy for the raw material cyclohexene, the cooling water dosage is greatly reduced, and the water vapor for warming is saved. Based on the current aim of energy saving and consumption reducing, the cooling medium and equipment for the 120000-ton hydration reactor are technically improved, and energy-saving effect of the patent can achieve 45% or more.

Description

technical field [0001] The invention relates to a method for increasing thermal efficiency of cyclohexanol hydration reactor equipment. Background technique [0002] Adipic acid, also known as fatty acid (AA for short), is the most important aliphatic dibasic acid, which can undergo condensation reaction with multifunctional compounds, such as hexamethylenediamine. It can undergo salt-forming reaction, esterification reaction, amidation reaction, etc., and can polycondensate with diamine or diol to form high molecular polymer. [0003] The generation of adipic acid mainly depends on the oxidation method of alcohol and ketone, and the production of alcohol and ketone by oxidation method has high energy consumption and low yield, and cyclohexane needs to take explosion-proof measures in contact with air, and the waste contains a large amount of organic acids that need to be treated. At the same time, the low conversion rate needs to solve the recovery and reuse of a large amo...
