Description
What the present invention relates to is a kind of renovation process of decolouring argil, and what the invention particularly relates to is a kind of renovation process of decoloring white clay grains.
Carclazyte is used for decolouring in industrial production widely uses.At present, because the most of oil field of China has entered the exploitation later stage, oil property is variation day by day, so the color of each oil plant production boat coal also becomes worse and worse and instability.For this reason, most of oil plant all adopts granular carclazyte to filter the boat coal, to deviate to navigate coal color and improve the stability of its color.But because the granular carclazyte poor water resistance can't adopt the regeneration of common hot water or steam, thereby cause a large amount of carclazytes discarded, can't handle, not only contaminated environment, and increase production cost.For this reason, the way that the oil plant that has adopts high temperature to cure is handled carclazyte, and in the hope of hot water regeneration carclazyte, but poor effect only can be recovered the active 50%-60% of carclazyte decolouring, and through twice or thrice just being done for after the regeneration.
The object of the present invention is to provide a kind of renovation process of decolouring argil, this method is not only simple for process, and can be at short notice the decolouring activation recovering of this inactivation carclazyte be reached more than 96%, use the carclazyte iterative regenerable of this method regeneration to use, the decolorizer of its use also can be recycled, and the no any murder by poisoning in whole regenerative process of this method is polluted.
For achieving the above object, the present invention is achieved by the following technical solutions: it mainly is to adopt solvent to the inactivation clay regeneration, and used solvent can be an industrial alcohol, also can be absolute ethyl alcohol; At first be colourless with this solvent washing inactivation carclazyte to the solvent that flows out, use this solvent soaking carclazyte then, the last solvent that with this solvent the carclazyte flushing of soaking is extremely flowed out again is colourless; Regenerative process after the carclazyte drying is finished.
In the said method, the time of solvent soaking carclazyte can be 12-24 hour.If the decolorizing effect of carclazyte is undesirable, the carclazyte after soaking for the first time is colourless through flushing to the solvent that flows out, but secondary soak, its soak time still is 12-24 hour.
The regeneration of can decolouring to the deactivated carclazyte of Any shape of this method.But the carclazyte to the decolouring of boat coal is preferably granular carclazyte.
The present invention has solved successfully that carclazyte can not be regenerated and common hot water or the bad problem of steam regeneration effect.Operation is simple for its regeneration technology, only needs to carry out just can finishing with certain flushing, immersion order with the decolouring solvent.The solvent that the present invention adopts is nontoxic, harmless, can not pollute environment, and the solvent of handling also can be recycled after distilling.Carclazyte with this method regeneration need not cure processing, and a large amount of carclazytes had both been saved in the use of also can instead regenerating after the carclazyte after the regeneration uses, and had alleviated the pollution of discarded carclazyte to environment again, had huge economic benefit and social benefit.
For showing that fully two groups of contrasting datas that provide below will further be discussed in detail with the better effects of this method regeneration carclazyte:
Investigate the treating capacity of granular carclazyte boiling water regeneration front and back to variable color boat coal
Under the normal temperature and pressure, adopt 1 gram self-control cure (320 ℃) granular carclazyte and 1 gram Fushun granular carclazyte simultaneously filter colors be No. 23 be mixed (low number boat coal with high number boat coal mixed preparing) boat coal, air speed is at 25h
-1-6h
-1Between, the boat coal color after filtering and raw material boat coal color near or stop to filter the processing that the accumulative total treating capacity of this moment is this carclazyte coal amount of navigating when equating.It the results are shown in shown in the following table 1:
Each granular carclazyte is handled the variation of boat coal amount before and after the regeneration of table 1 boiling water
Add up again to handle from a living amount, restrain the preceding color of 300 620 870 1,107 1,533 1753 granulations, numbers 30 29 27 28 27 24 bakings add up to handle the autochthonal amount of roasting in vain again, restrain 217 426 586 779 989
Back color, numbers 30 30 28 27 24
Add up to handle to comfort the amount of giving birth to again, restrain 344 684 946 along the Cynanchum glaucescens color, number 30 26 23 soil add up to handle grain again and give birth to amount, restrain 198 403 586
Back color, numbers 30 27 23
By table 1 as seen, self-control is cured (320 ℃) granular carclazyte and Fushun granular carclazyte the treating capacity of No. 23 boat coals that are mixed is respectively 1753 times and 989 times before the regeneration, and its treating capacity is respectively 946 times and 586 times after the boiling water regeneration.Boiling water regeneration back granular carclazyte active regeneration rate is about about 50%-60%.Also can find out the treating capacity of the treating capacity of self-control granular carclazyte simultaneously greater than the Fushun granular carclazyte.Low number boat coal component owing to be mixed in the boat coal is through being exposed to the sun, and the chromaticness of the boat that is mixed coal is relatively poor, so the processing of each granular carclazyte boat coal amount is on the low side.
Investigate the treating capacity of the new method regeneration of granular carclazyte front and back to variable color boat coal
Because granular carclazyte boiling water regeneration back activation recovering rate only is 50%-60%, through twice or thrice just being done for after the regeneration, its accumulative total treating capacity is still very low, still can cause a large amount of carclazytes discarded, contaminated environment like this.For this reason, the present invention proposes a kind of new clay regeneration, with two kinds of granular carclazytes of boiling water regeneration back inactivation in this new method regeneration table 1 and make common (not high-temperature process) granular carclazyte by oneself, and compare with the processing boat coal amount of new clothes (for the first time effect) self-control plain particles carclazyte and new clothes Fushun granular carclazyte, investigate of the variation of the amount of its 1 gram, the results are shown in shown in the following table 2 No. 23 expired boat coals and 905 jars of No. 22 boat coal treating capacities.
Each granular carclazyte of the new method regeneration of table 2 back is handled the variation of boat coal amount
| From a granulation Pu Baitong soil | (use) the accumulative total treating capacity before the regeneration for the first time, the gram color, number | 1090 30 | 1280 1460 28 29 | 1730 1920 25 23 |
| New method regeneration back (using for the second time) accumulative total treating capacity, the gram color, number | 1152 30 | 2434 3096 29 27 | 3520 4709 4882 27 26 23 | |
| From the white roasting soil of a granulation baking | New method regeneration back (using for the third time) accumulative total treating capacity, the gram color, number | 1812 30 | 2101 3737 29 28 | 5216 5640 6715 6935 28 27 26 23 |
| White the grogs in Fushun | (use) the accumulative total treating capacity before the regeneration for the first time, the gram color, number | 4449 30 | 5210 5999 29 28 | 7641 9694 10818 27 26 24 |
| New method regeneration back (using for the third time) accumulative total treating capacity, the gram color, number | 3929 30 | 5765 6120 30 29 | 7021 8058 9895 10392 28 27 26 24 |
Annotate: the boat coal is used No. 24 boat coals of true boiling point distillation alkali cleaning instead behind the thick line, and the boat coal is used 905 jars No. 22 boat coals instead behind the fine rule.
By table 2 as seen, though each granular carclazyte through twice use before and after the boiling water regeneration, activity still increases substantially through new method regeneration back, the activation recovering rate reaches 96% (the Fushun granular carclazyte treating capacity first time and treating capacity merchant's percentage) for the third time.Self-control plain particles clay treatment boat coal amount through new method regeneration is added to 4882 times by 1920 multiplications before regenerating; Associative list 1 as can be seen, 586 multiplications after the Fushun granular carclazyte of new method regeneration is handled boat coal amount before by boiling water regeneration 946 times and boiling water regeneration for the second time are added to 10392 times, to handle 10818 times of the coal amounts of navigating suitable with the new clothes granular carclazyte; For the second time cure 989 multiplications that granular carclazyte handles after boat coal amount before by boiling water regeneration 1753 times and the boiling water regeneration and be added to 6935 times through the self-control of new method regeneration.
