Description
Technical field
The present invention relates to a kind of containing phenol fraction of naphthalene oil treatment unit and method for washing and processing, specifically washing tower pretreating device and method for washing and processing.
Background technology
Deeply add industry at coal tar, what in coal tar distillation process, coal tar distillation tower produced contains phenol fraction of naphthalene oil, containing phenol amount, generally in about 4.0-4.5%, the boiling point of such boiling point substance and naphthalene is close, very easily sneaks into NAPTHALENE FLAKES. (INDUSTRIAL GRADE） and affect quality product in the time of rectifying deep processing.For improving the quality of NAPTHALENE FLAKES. (INDUSTRIAL GRADE） and extracting these products, before rectifying deep processing, need to carry out alkali cleaning and pickling containing phenol fraction of naphthalene oil, to be reduced in below 0.5% containing phenol content in phenol fraction of naphthalene oil, and wash fraction of naphthalene oil and can be used as producing that NAPTHALENE FLAKES. (INDUSTRIAL GRADE） rectifying produces enters rectifying tower raw materials for production.Coal tar distillation out containing phenol fraction of naphthalene oil go out to exist in advance temperature be 70～80 DEG C containing in phenol naphtalene oil storage tank, then squeeze in washing tower by containing phenol fraction of naphthalene oil pump containing phenol fraction of naphthalene oil, 30% alkali lye joins in washing tower by lye pump, the fraction of naphthalene oil of washing of scrubber overhead discharge has been washed naphtalene oil groove from flowing into, as NAPTHALENE FLAKES. (INDUSTRIAL GRADE） system raw materials for production oil.Wash tower bottoms is discharged alkaline phenates, and alkaline phenates enters the alkaline phenates groove in medial launder district.
In washing tower, contain after phenol fraction of naphthalene oil fully mixes contact with 30% alkali lye of washing use and separate again, generate alkaline phenates containing aldehydes matter and alkaline reaction in phenol fraction of naphthalene oil.Remove and wash fraction of naphthalene oil through NAPTHALENE FLAKES.
