cov bitumen cov txheej txheem ntau lawm hloov cov roj crude rau hauv cov ntaub ntawv ruaj khov rau txoj kev, lub ru tsev, thiab cov ntaub ntawv tsis muaj dej. Txhua theem ua hauj lwm nyob rau hauv nruj kub thiab siab tswj los xyuas kom meej cov khoom zaum kawg nyob ruaj khov thiab nyab xeeb.
Basekim, ib tug ntseeg bitumen tsum los ntawm Qaib Cov Txwv thiab UAE, ua raws li cov qauv thoob ntiaj teb los tsim thiab xa tawm cov qib zoo tshaj plaws thoob ntiaj teb.

Kauj Ruam 1: Roj Crude Desalting

Cov txheej txheem pib thaum engineers xa cov roj crude rau hauv ib qho desalting unit. Lawv ntxuav cov dej, ntsev, thiab cov khib nyiab me me ua ntej pib cua sov.

Vim tias ntsev tuaj yeem corrode cov kav dej, tshem tawm thaum ntxov tiv thaiv cov cuab yeej thiab txhim kho cov kauj ruam tom ntej. Yog li ntawd, lub feedstock nyob twj ywm huv si thiab npaj rau meej distillation.

Kauj Ruam 2: Atmospheric Distillation

Tom ntej no, cov roj huv nkag mus rau hauv atmospheric distillation unit (ADU). Sab hauv, cov cua sov ua kom kub txog li 370 ° C.

Cov khoom siv lub teeb xws li naphtha, kerosene, thiab roj roj nce mus rau saum toj, thaum cov feem hnyav nyob hauv qab. Qhov dej hnyav no hu ua atmospheric residue, ua lub hauv paus rau kev kho kom zoo ntxiv.

Kauj Ruam 3: Nqus Distillation

Tom qab ntawd lub atmospheric residue ntws mus rau hauv lub Lub tshuab nqus tsev distillation (VDU). Cov kws kho tsheb txo qis kom cia kev sib cais tshwm sim ntawm qhov kub thiab txias.
Vim tias lub kaw lus tsis txhob tawg, cov molecules hnyav tseem muaj zog. Cov khoom uas nyob tom qab yog cov nqus tsev hauv qab, lub ntsiab pub rau bitumen.
Nyob rau theem no, cov kws kho mob saib xyuas t

Qhov kub thiab txias (400 ° C) thiab siab (25-40 mmHg) kom viscosity thiab softness zoo ib yam.

Kauj Ruam 4: Cua tshuab (Oxidation)

Tam sim no lub tshuab nqus tsev hauv qab txav mus rau qhov cua tshuab reactor. Cua kub dhau los ntawm nws nyob ib ncig ntawm 250 ° C, thiab oxygen reacts nrog cov roj.
Cov tshuaj tiv thaiv no nce qhov hnyav molecular thiab nce qhov muag muag. Qhov tshwm sim yog oxidized bitumen, zoo meej rau vov tsev thiab waterproofing.
Cov neeg ua haujlwm taug qab cov viscosity hauv lub sijhawm tiag tiag thiab nres cov tshuaj tiv thaiv raws nraim thaum cov bitumen ncav cuag nws cov hom phiaj qib.

Kauj Ruam 5: Txias thiab lim

Tom qab oxidation, cov khoom kub ntws los ntawm cov cua sov sib hloov kom txias. Ces nws hla dhau zoo lim uas ntes cov pa roj carbon thiab cov khoom seem.
Vim tias cov ntxaij lim dej ntxuav txhua cov khoom, cov bitumen tau txais kev ntxhib los mos, ruaj khov. Cov kauj ruam no ua kom zoo sib xws rau kev cia thiab xa tawm.

Kauj Ruam 6: Cia thiab Blending

Tom ntej no, cov bitumen nkag mus insulated steel tanks nruab nrog cua sov coils thiab qib sensors. Cov tso tsheb hlau luam khaws cov khoom ntawm 150 ° C thiab 180 ° C.
Engineers feem ntau muab sib txawv batch kom phim yuav tsum tau nkag mus los yog viscosity.
Rau kev ua tau zoo dua, lawv tuaj yeem ntxiv SBS lossis EVA polymers, tsim polymer-hloov bitumen (PMB) uas ua tau zoo dua nyob rau hauv tshav kub thiab kev nyuaj siab tsheb.

Kauj Ruam 7: Ntim thiab Export

Thaum kuaj kuaj pom tseeb tias cov bitumen sib ntsib ASTM thiab EN cov qauv, Basekim npaj nws rau kev xa khoom.
Cov kev xaiv ntim khoom muaj xws li:

• Hlau nruas (150 kg)

• Jumbo hnab (1 MT)

• Meltable PE hnab (20-25 kg)

• Cov tankers loj thiab ISO ntim

Vim hais tias Basekim khiav niaj hnub filling thiab tshuaj xyuas tshuab hauv Qaib ntxhw thiab UAE, txhua qhov khoom xa tuaj nyob nyab xeeb, kaw, thiab tsis sib xws.

Bitumen Production Process Flow Diagram

Ntawm no yog ib daim ntawv qhia meej ntawm cov bitumen ntau lawm txheej txheem ntws daim duab:

Txuas nrog Asphalt Production Process

Tom qab kev tsim khoom, bitumen dhau los ua cov khoom tseem ceeb hauv cov khoom asphalt cov txheej txheem ntau lawm.
Ntawm asphalt nroj tsuag, nws sib tov nrog aggregates ntawm 160 ° C los ua asphalt kub. Vim cov ntshiab bitumen muaj zog adhesion, nws xauv pob zeb ua ke thiab ua kom txoj kev du rau xyoo.
Yog li ntawd, kev tswj kom zoo ntawm lub refinery ncaj qha cuam tshuam rau txoj kev ua neej.

Green Technology thiab Innovation

Niaj hnub nimno refineries siv cov hluav taws xob txuag hluav taws xob, fume-capture systems, Thiab recycled cua sov rov qab tiv thaiv ib puag ncig.
Tsis tas li ntawd, engineers tsim bio-based binders thiab Recycled asphalt blends txiav emissions.
Basekim kuj siv tau AI-based viscosity xyuas, uas txo lub zog pov tseg thiab khaws cov khoom sib xws ntawm qib siab tshaj plaws.

Xaus-Bitumen Production Process

cov Cov txheej txheem tsim khoom ntawm bitumen combines chemistry, tshav kub, thiab precision. Txhua kauj ruam tswj tau hloov cov roj crude mus rau hauv ib tug muaj zog thiab saj zawg zog binder.
Nrog cov thev naus laus zis niaj hnub thiab cov qauv zoo thoob ntiaj teb, Basekim - los ntawm Qaib ntxhw thiab UAE - muab cov qib bitumen txhim khu kev qha rau kev tsim kho, waterproofing, thiab industrial tej yaam num nyob ib ncig ntawm lub ntiaj teb no.
