186 rectify operation is exercise of a chemical industry, its main executive facility is rectification tower, no matter be,be being returned to craft is equipment, should have an objective opinion, serve as equipment and the basis that craft popularizes with this. Finish the rectify of relevant material to operate through rectification tower, how does whole process quality have a lot of index to be able to be measured, for instance of the purity of the product, constituent reclaim rate and manufacturing cost are waited a moment.
1, the purity of product of the earning after rectification tower finishs rectification to operate
As one of main index that measure craft and equipment stand or fall, the purity of the product and very much element are concerned forest, the affiliation of fluid of the height of layer of the tray number that included rectification tower, filling, makings the position, circumfluence comparing is waited a moment, the adjusting control that passes pair of this a few respects so can achieve the improvement of pair of rectification product purity.
2, the constituent that rectification tower produces a product reclaims rate
So called constituent reclaims rate, what basically point to is the ratio of content of the constituent in content of the constituent in the product and makings fluid, reclaim rate is higher, the effect that shows rectification tower is better.
3, the total manufacturing cost in rectification process
The content that rectification cost includes basically has two much, the devoted cost that is rectification tower partly and depreciation cost are used, still have the cost of specific power consumption that is rectification process partly, for instance again boil implement heat the charge, cooling charge of condenser is waited a moment.
If say former it is fixed word, change the circumfluence comparing, boiling temperature, condensing temperature, setting that operates the parameter such as pressure matters when latter and operation, must install ability reasonably to reduce the generation of charge so.
4, rectification tower is long need not hind the premise condition that uses again
To long tower of unused unused rectify, as long as can if each field requirement can be satisfied, still organic meeting is applied again. But premise is to should make sure its can be used normally, and accord with use requirement, it is right very after equipment undertakes school nucleus, redo decides.
If want reuse, the circle is strengthened outside be necessary to be installed for rectification tower; And the solution that the mouth that is put possibly below negative pressure circumstance fills to be not inscribed by force through asking. If ask the problem is solved and if satisfying rated condition, rectification tower will be thrown to use again.
