[0002] In the continuous reforming process of petroleum chemical industry, the process condensate is an important by-product in the production process, and its treatment process is crucial to the stable operation of the whole system. After these condensates are collected, they are directly cooled and treated in the condensate water air cooler because they contain gas-liquid two-phase; in the air cooler, the temperature of the condensate is gradually reduced to 90 DEG C through heat exchange.
