Sealing nruab nrab solidification, polymerization, coking, crystallization, thiab lwm yam.
Rau petrochemical tshuab twj tso kua mis seals, kuj yuav tsum tau them nyiaj mloog kom tsis txhob deterioration ntawm lub sealing nruab nrab vim yog kub hloov.
1. Kho
Rau qhov nruab nrab sealing nrog siab khov taw tes, yuav tsum tau them nyiaj rau qhov teeb meem ntawm cov kua solidification, xws li paraffin, wax roj, residual roj, asphalt, urea, molten sulfur, thee tar, phenolic resin, plasticizer, thiab lwm yam. tiv thaiv kom tsis txhob muaj zog, ua kom rov qab ua kom txias tuaj yeem siv tau, thiab kev ntxuav thiab kev txuag hluav taws xob yuav tsum tau ua kom tsis txhob muaj qhov kub thiab txias kom poob qis hauv qhov chaw khov.
2. Kev sib sau ua ke
Rau kev sib khi ntawm cov xov xwm uas yuav ua rau polymerization vim qhov kub thiab txias, ua kom sov thiab tsis tshaj qhov kub ntawm polymerization, xws li furfural, formaldehyde, styrene, vinyl chloride, acrolein, vinyl acetate, formaldehyde, raffinate, thiab lwm yam. , cascade sealing tuaj yeem siv los ua kom muaj cua txias txaus los tiv thaiv qhov kub thiab txias.
3. Crystallization
Rau kev yooj yim crystallization media, xws li ammonium sulfate, ammonium phosphate, caustic soda, calcium hydroxide, phosphoric acid, amine, ntsuab cawv, thermal conductivity, butanol, thiab lwm yam, nws yog ib qho yooj yim mus crystallize nyob rau hauv chav tsev kub, thiab cov teeb meem yaj yuav yog. precipitated vim kev hloov ntawm solute. Rau kev sib khi ntawm hom nruab nrab no, yuav tsum tau siv ib qho kev sib txhuam nyuaj rau kev sib txhuam, thiab yuav tsum tau muab cov cua txias txaus los yog kev txuag hluav taws xob.
4. Ua kua
Rau isopropanol, sulfonated roj, alum, sodium sulfate, poov tshuaj sulfate (rau dej), pentane (rau roj), roj hmab (rau kua ammonia, benzene, ammonia, thiab lwm yam) nrog siab solubility (rau dej, roj los yog ethanol, thiab lwm yam. ) thiab lwm yam) thiab glycerol (rau ethanol) thiab lwm yam xov xwm, yuav tsum xyuam xim rau kev siv xov xwm thiab kev sib cais ntawm cov khoom siv.
5. Cov teeb meem xws li coking, corrosion, abrasion, thiab lwm yam yog tsim los yog exacerbated ntawm qhov kub thiab txias, thiab qhov kub thiab txias yuav tsum tau tiv thaiv kom zoo.
