Petcoke thiab Coal: Kev Sib Piv Kev Ntsuas Kev nkag siab txog qhov sib txawv thiab kev siv Petcoke thiab CoalPetcoke thiab thee yog ob qho tib si carbonaceous cov ntaub ntawv siv hauv ntau daim ntawv thov kev lag luam, tab sis lawv muaj cov khoom sib txawv thiab cov yam ntxwv. Kab lus no tshawb txog qhov sib txawv tseem ceeb ntawm pev coal, lawv cov kev siv, thiab kev xav txog ib puag ncig.

Petcoke yog dab tsi?

Petroleum coke, los yog petcoke ua, yog carbonaceous cov khoom seem uas tshuav tom qab lub refining ntawm hnyav crude roj. Nws feem ntau yog tsim los ntawm carbon, nrog rau me me ntawm hydrogen, sulfur, thiab lwm yam impurities. Cov yam ntxwv ntawm petcoke ua sib txawv nyob ntawm seb hom roj crude ua tiav thiab cov txheej txheem refining siv. Muaj ob hom loj: ntsuab coke (calcined) thiab qeeb coke (uncalcined). Ntsuab coke, feem ntau siv hauv txhuas smelting, yog tsim los ntawm cov txheej txheem calcination uas tshem tawm cov teeb meem tsis zoo thiab txo cov ntsiab lus ntawm cov sulfur. Ncua coke, nrog cov ntsiab lus sulfur siab dua, pom daim ntawv thov hauv ntau qhov kev lag luam, suav nrog cov cement ntau lawm thiab tsim hluav taws xob.

Coal yog dab tsi?

Coal yog ib lub pob zeb uas tshwm sim nyob rau hauv feem ntau ntawm cov pa roj carbon monoxide nrog rau ntau qhov sib txawv ntawm hydrogen, sulfur, oxygen, thiab nitrogen. Nws tsim los ntawm tsub zuj zuj thiab compression ntawm cov nroj tsuag thaum ub ntau lab xyoo. Ntau hom thee muaj nyob, cais raws li lawv cov ntsiab lus carbon thiab qib, suav nrog anthracite, bituminous, sub-bituminous, thiab lignite. Qhov zoo thiab cov khoom ntawm cov thee sib txawv heev nyob ntawm nws qib thiab geological keeb kwm. Cov qib siab coals muaj cov ntsiab lus carbon ntau dua thiab muaj zog dua.

Cov khoom ntawm Coal

Cov ntsiab lus sib txawv ntawm cov pa roj carbon monoxide (nyob ntawm qib) Lub zog tsis sib xws (nyob ntawm qib) Cov ntsiab lus tsis sib xws ntawm sulfur (nyob ntawm qib thiab keeb kwm) Muaj ntau yam kab kawm thiab cov zaub mov muaj txiaj ntsig zoo.

Petcoke vs. Coal: Ib qho piv txwv

Feature	Petcoke	Thee
Keeb kwm	Petroleum refining byproduct	Ntuj tshwm sim sedimentary pob zeb
Cov ntsiab lus carbon	Feem ntau siab (90-95%)	Hloov pauv, nyob ntawm qib (piv txwv li, anthracite> bituminous)
Cov ntsiab lus sulfur	Variable, tuaj yeem ua tau siab hauv qee hom	Hloov pauv, nyob ntawm qib thiab keeb kwm
Zog Ceev	Siab	Hloov pauv, nyob ntawm qib
Daim ntawv thov	Aluminium smelting, cement ntau lawm, tsim hluav taws xob	Kev tsim hluav taws xob, kev tsim steel, kev tsim cov cement, ntau yam kev lag luam

Environmental Considerations

Ob leeg petcoke ua thiab thee combustion ua rau huab cua muaj kuab paug, tso cov pa hauv tsev cog khoom (xws li CO2) thiab lwm cov pa phem (xws li SOx thiab NOx). Qhov kev cuam tshuam ib puag ncig nyob ntawm yam xws li cov ntsiab lus sulfur ntawm cov roj thiab kev ua haujlwm ntawm emission tswj technologies ua haujlwm. Cov kev coj ua ruaj khov, suav nrog kev ntes cov pa roj carbon monoxide thiab khaws cia, yog qhov tseem ceeb los txo qhov cuam tshuam ib puag ncig ntawm kev siv cov roj no.

Xaus

Petcoke thiab thee yog ob qho tib si tseem ceeb ntawm lub zog nrog ntau yam kev siv hauv ntau yam kev lag luam. Kev nkag siab txog lawv cov khoom thiab kev cuam tshuam ib puag ncig yog qhov tseem ceeb rau kev paub txog kev txiav txim siab. Qhov kev xaiv ntawm petcoke ua thiab cov thee feem ntau nyob ntawm cov kev xav tau tshwj xeeb hauv kev lag luam, kev xav txog tus nqi, thiab kev tswj hwm ib puag ncig. Kev tshawb fawb ntxiv thiab kev tsim kho tshiab yog xav tau los tshawb nrhiav kev siv hluav taws xob huv thiab ruaj khov dua.
