Vim li cas tus nqi roj nce, thiab ces tus nqi ntawm cov tshuaj fibers kuj nce?

Muaj ob peb qhov laj thawj sib cuam tshuam vim li cas cov nqi roj nce thiab tom qab ntawd cov khoom lag luam qis xws li cov tshuaj fiber ntau ua raws cov nqi siab dua. Nov yog lub ntsiab lus luv luv uas koj tuaj yeem siv los nkag siab cov saw:

Roj raws li lub hauv paus ntsiab lus

Roj yog cov khoom noj thiab lub zog rau ntau cov txheej txheem tshuaj. Cov nqi roj av siab dua ua rau tus nqi tsim cov khoom siv petrochemical (ethylene, propylene, thiab lwm yam), uas yog lub tsev thaiv rau cov khoom siv hluavtaws.

Thaum cov nqi roj nce ntxiv, cov chaw tsim khoom thiab cov chaw tsim tshuaj lom neeg ua rau cov nqi hluav taws xob ntau dua thiab cov khoom siv raw, uas tau dhau los ntawm tus nqi ntawm cov khoom tiav.

Ntiaj teb no supply/xav tau dynamics

Kev cuam tshuam kev xa khoom lossis kev tsis sib haum xeeb ntawm thaj chaw (xws li, kev tsis sib haum xeeb, kev rau txim, kev txiav txim siab ntau lawm OPEC) tuaj yeem thawb cov nqi roj av.

Kev thov hauv kev lag luam loj hlob (Tuam Tshoj, Is Nrias teb, thiab lwm yam) rau lub zog thiab petrochemicals tuaj yeem thawb tus nqi siab dua, tshwj xeeb tshaj yog tias cov khoom tsis tuaj yeem ntsuas tau sai.

Kev sib txuas ntawm roj av thiab petrochemicals

Ntau cov khoom siv petrochemical tau muab los ntawm naphtha lossis cov kua roj nkev, uas yog tus nqi txheeb ze rau roj. Kev nce hauv cov roj crude feem ntau txhais ua cov nqi siab dua rau naphtha-raws li cov khoom siv.

Tus nqi ntawm polymers thiab fibers (xws li polyester, ib qho hluavtaws fiber ntau) nyob ntawm ethylene thiab terephthalic acid, ob qho tib si txuas rau cov roj crude ntawm feedstocks thiab cov nqi zog.

Kev xa mus rau fibers

Synthetic fibers (piv txwv li, polyester, nylon) cia siab rau petrochemical intermediates. Yog tias tus nqi ntawm ethylene lossis benzene nce, cov nqi tsim khoom rau cov fibers no nce.

Airlines, textiles, thiab ntim xav tau tuaj yeem cuam tshuam tus nqi rau cov khoom siv polymer. Yog tias qhov kev thov rau cov fibers muaj zog (lub caij zam, kev thov rau cov khoom ruaj khov), cov tuam txhab yuav dhau cov nqi nkag siab dua rau cov neeg siv khoom.

Cov khoom muag thiab cov qauv kev lag luam cuam tshuam

Cov tub lag luam khaws cov roj av lossis cov khoom noj khoom haus thaum yav tom ntej nkhaus qhia cov nqi siab dua yav tom ntej, uas tuaj yeem thawb cov nqi nce.

Kev ua lag luam nruj hauv cov khoom siv polymer (tseem muaj peev xwm, kev tswj xyuas kaw, lossis txwv kev xa tawm) tuaj yeem ua rau tus nqi nce ntxiv rau fibers.

Lag thiab dhau - dhau

Kev hla- los ntawm cov roj mus rau fibers tsis yog ib txwm tam sim ntawd. Yuav muaj kev lag luam raws li cov ntawv cog lus, cov khoom muag, thiab kev tiv thaiv kev cuam tshuam tus nqi txav. Thaum cov neeg tsim khoom kho tus nqi, cov khw muag khoom thiab textile manufacturers yuav nce nqi fiber ntau los tiv thaiv cov npoo.

Lwm yam kev pab cuam (contextual)

Tus nqi pauv: Ib qho txiaj ntsig hauv zos tsis muaj zog tuaj yeem ua duas duas - cov roj thiab petrochemicals kim dua hauv zos.

Kev thauj mus los thiab cov nqi thauj khoom: Cov nqi thauj khoom siab dua tuaj yeem nce nqi ntshuam rau fibers thiab fabrics.

Environmental thiab txoj cai yam tseem ceeb: Cov kev cai lossis cov nqi carbon tuaj yeem nce nqi hluav taws xob, cuam tshuam rau cov khoom siv roj av thiab tshuaj lom neeg.
