Do not know whether everybody follows small like making up, also the extensive sex that experience crosses rectification tower utility, be in especially chemical industry this one domain, can produce synthesis with it a lot of products, contented and different manufacturer the demand to industrial chemicals. Serve as a kind among them, the demand of industrial naphthalene also is bigger, use rectification law production mostly at present, and many what the manufacturing technology of double tower of odd furnace odd tower, odd furnace double tower or double furnace uses.
When make, should have raw material heating first and dormant dehydrate, send to heat exchanger and heat exchange of industrial naphthalene vapour then; Throw gotten result primary tower reaction then. Until hind, industrial naphthalene will be collected from rectification cat head piece, but still naphthalene of one part industry will serve as rectification tower circumfluence to control temperature of vapour of rectification cat head, still have one share industrial naphthalene gets after cooling crystallization piece shape crystallization finished product. In whole preparation process, need detects and automata has a lot of to frontal project, but the key is in temperature respect, include to cat head temperature accuses and be in charge of type furnace to export oily temperature control. Ask according to craft the circumstance of the operation falls strictly only, industrial naphthalene ability is generated smoothly from inside rectification tower, and assure good quality.
