Phenol water treatment system
Technology application
Phenol water overall treatment in gas plant, phenol water zero release.
Technology introduction
Neutralizing treatment will be done after condensate water is collected and sent to phenol water collection pools. Phenol water will be pumped to cyclone water jacket or gasifier water jacket(if phenol water is excessive) after neutralizing treatment, coarse and precision filtration. Waste heat(approx. 450~500℃) of down stage gas can be used for heat exchange with phenol water in cyclone water jacket. Phenol steam goes into steam drum for steam-water separation after some low boiling point benzene and phenol are vaporized by sensible heat of gas. Steam contains phenol, as gasification agent, will be sent to gasifier to participate chemical reactions. Waste heat can be used for phenol water treatment, and at the same time gas temperature can be decreased. The temperature of oxidation layer in gasifier is generally 1000—1200℃, therefore benzene and phenol can be split into water and carbon dioxide under such temperature, the reaction equation is C6H5OH+7O2=6CO2+3H2O。
Treatment process
Product superiority
The technological process has the advantages of environmental protection and energy saving, phenol water has no external discharge, a good operation environment is guaranteed.
