To ensure rectification tower is whole the stability of rectification process, a lot of essential conditions need to have, among them one of it is circumfluence. Also be to say, circumfluence has important sense to rectification tower, if that is complete circumfluence? The result with different what can you bring again?
When rectification tower moves, after the steam that its produce coagulates via super-cooling in cat head, will all circumfluence arrives in rectification tower, such word, arise without cat head not only, also do not have feed in raw material normally, go out without tower boiler, also cannot get rectification product. Because this is opposite,any meanings are less than since normal production. But if rectification tower is applied in, did not satisfy craft to set a requirement because of chroma of stock of boiler of cat head, tower and cannot collect piece send downward working procedure when, can carry complete circumfluence operation, make chroma of stock of boiler of cat head, tower OK quality requirement is achieved in short time. Be in at the same time proper when remove complete circumfluence, fill add stock, the moving condition that rectification tower can return to normal again.
