Abstract
The present invention is applicable to the process for preparing acetylene by cracking natural gas (methane). Said invention utilizes the partial carbon black by-product formed in the course of the above-mentioned process, and makes it undergo the processes of floating, washing, drying, detecting and packaging so as to obtain natural gas carbon black product. Then said invention can make the by-product carbon black undergo the processes of medicinal floatation, separating high-quality carbon black from impurity organic matter, washing, dewatering, spray-drying so as to obtain the medicinal preparation whose temp. can be controlled at about 200 deg.C.
Description
The invention belongs to Sweet natural gas (methane) system acetylene and produce part carbon black process, by product carbon is carried out flotation, washing, drying, thereby form qualified Sweet natural gas (methane) cracking black carbon, its quality level is similar to the Sweet natural gas thermally oxidized black.
Present method is applicable to the big production of the industry of Sweet natural gas (methane) preparing ethyne by cracking.
The tradition natural gas pyrolysis is produced carbon black, consumption Sweet natural gas height, annual this method output of China is also picked up more than ten thousand tons at number, calculate according to every T consumption gas 8000m2, just have number and pick up hundred million valuable gas consumptions, and the recovery of the natural gas pyrolysis system of utilization acetylene by product carbon, utilize, just can economize in raw materials greatly, turn waste into wealth, form benefit.Calculate with cracking 5% by-product, the olefin plant of one 10 ton, (as vinylon, vinyl acetate between to for plastic) just has number and does the recycling of ton carbon black, saves Sweet natural gas (methane) with ten million cube of calculating.Use the benefit that present method reached, its price advantage obviously is obvious and huge!
Present method process is:
One, flotation
A, irregular by product carbon input is furnished with in molten Ji (water) pond of flotation reagent, its water and material ratio are water 3, thing 1, add to stir to allow it fully be uniformly dispersed, and flotation medicine master contains polymerization iron aluminium flocculating agent for suitable, has the throwing out that machine suspends.
B, adjustment pH value are about inclined to one side subacidity 6-5, and silt in the carbon black and heavy metal thing are deposited earlier, and the organic suspension thing also pursues portion's flocculation sinking, thereby impurity and material branch are come.
Two, washing:
Settling is removed in discharging, washs carbon black with clear water, still with stirring it is uniformly dispersed to suitable, water and material ratio be 1: 1 be to fit, water can surpass material.
Three, drying
The carbon black of washes clean is stirred drying down at 200-300 ℃, be preferably spraying drying and form product.
Four, detect, pack, put in storage.
Example 1
A, with 500Kg by product carbon material, drop in the agitated pool, add water 1.5T-2T, drop into flotation medicine 0.2Kg, this medicine for poly-iron-based for suitable, adjusting PH is 6, fully stirs quiet putting 1 hour 1 hour.Impurity separates with sooty in the formation raw material.
B, removing deposition impurity wash quiet putting 1 hour again in stirring with clear water.
C, take out with compressor and to press the carbon black be suspended in the clear water, enter drying after, temperature control is below 200-300 ℃, spraying drying.
D, inspection, drying products, qualified back packing, warehouse-in.
Example 2
A, fortune 3m
3Nature pulpous state by product carbon material drops into 12m
3In the pond, adding soil release agent is the floating medicine 0.5Kg (as iron trichloride) of base-material, adjusts pH value and is 5.5 ∽ 6 and fully stirred after 1 hour quiet 1 hour, allows contaminant filter separate from mixture, to deposit.
B, remove sedimentary impurity, add clear water agitator treating in the pond, the water yield is 1: 1 of material, quiet putting 1 hour.
C, with material filtering, bleed off washing water.
D, again will filter carbon black add in the dry charcoal that stirs of band, tumble dried, temperature control about 200 ℃, 1 hour.
E, its relevant index of inspection product moisture content, qualified back packing, warehouse-in.
Example 3
A, with the carbon black feed stock 1000Kg that cleans out in the natural gas pyrolysis system acetylene, drop in the agitated pool on the clean water basin 3m3, add about iron aluminium polymerization coagulating agent 0.3Kg, transfer pH value 6, fully stirred 1 hour, static 1 hour, impurity in the carbon black feed stock is separated to come out clearly.
B, arrange throw out and excessive moisture clearly, add 100% flushing with clean water again.
C, with the carbon black of rinsing well, the dehydration of vacuum or speed reducing centrifugal.
D, the carbon black material after will dewatering be selected into about 200 ℃, stir down in the moisture eliminator dry.
E, inspection moisture content and other index, qualified back packing, warehouse-in.
Claims (5)
- The recycling way of Sweet natural gas (methane) system Shawinigan black, its content and feature are divided following several aspect:1, the carbon black of by-product is the recycling object in Sweet natural gas (methane) cracking.
- 2, the carbon black with by-product carries out flotation, wherein uses iron aluminium coagulating agent pharmacy effect the best as base-material, PH be 6-5 be suitable water addition ratio example water is greater than raw material more than 3 times in principle, fully dispersed with stirring is for suitable.
- 3, with the surplus water and the deposition of flotation separation, throw out is removed and is drained, and carries out the clear water washing again, and it is better to repeat quadratic response.
- 4, drying is carried out in the carbon black of washes clean was dewatered leakage, and temperature is controlled between the 150-250 to suitable, eliminates moisturely, uses spraying drying can a step carbon black dry materials of washes clean to be finished, temperature control about 200 ℃ for suitable.
- 5, detect moisture content and other corresponding index, be packaged into product after up to standard.
