** Taw qhia
LPG thiab propane feem ntau yog siv los ua roj hauv ntau daim ntawv thov, suav nrog thaj chaw nyob, kev lag luam, thiab chaw tsim khoom. Txawm li cas los xij, feem ntau tsis meej pem txog seb ob lo lus no hais txog tib yam lossis tsis yog. Hauv tsab xov xwm no, peb yuav tshuaj xyuas qhov sib txawv thiab qhov sib xws ntawm LPG thiab propane, suav nrog lawv cov tshuaj lom neeg, khoom, ntau lawm, thiab kev siv.
** LPG yog dab tsi?
LPG stands rau liquefied petroleum gas, uas yog ib tug sib tov ntawm hydrocarbon gases uas yog tsim thaum lub sij hawm refining ntawm cov roj crude thiab natural gas. Lub ntsiab Cheebtsam ntawm LPG yog propane thiab butane, txawm hais tias lwm yam gases, xws li ethane thiab propylene, kuj tseem muaj nyob rau hauv me me.
** propane yog dab tsi?
Propane yog cov roj tsis muaj xim, tsis muaj ntxhiab tsw uas muaj nyob hauv tsev neeg alkane ntawm hydrocarbons. Nws cov qauv tshuaj yog C3H8, uas txhais tau hais tias nws muaj peb carbon atoms thiab yim hydrogen atoms. Propane yog ib qho khoom siv los ntawm kev ua cov pa roj carbon monoxide thiab cov roj crude refining. Nws feem ntau yog siv los ua roj rau cua sov thiab ua noj, nrog rau hauv kev lag luam xws li vuam, soldering, thiab brazing.
** Tshuaj muaj pes tsawg leeg
LPG thiab propane tsis zoo ib yam, tab sis propane yog ib qho tseem ceeb ntawm LPG. Qhov tseeb, propane ua txog li 60% ntawm LPG, thaum butane tso nyiaj rau 40%. LPG kuj tseem muaj cov roj me me, xws li ethane thiab propylene.
Cov tshuaj muaj pes tsawg leeg ntawm propane yog qhov yooj yim, muaj peb cov pa roj carbon atoms thiab yim hydrogen atoms. Nws qhov hnyav molecular yog 44.097 g / mol, thiab nws cov ntsiab lus kub yog -42.1 degrees Celsius (-43.8 degrees Fahrenheit). Propane yog ib qho hluav taws xob hluav taws xob uas tuaj yeem ignite yooj yim nyob rau hauv lub xub ntiag ntawm lub txim taws los yog nplaim taws.
** Khoom
LPG thiab propane muaj cov khoom zoo sib xws tab sis kuj muaj qee qhov sib txawv. Nov yog qee qhov tseem ceeb ntawm LPG thiab propane:
- LPG thiab propane yog ob qho tib si hluav taws kub heev thiab tuaj yeem ignite yooj yim nyob rau hauv lub xub ntiag ntawm nplaim taws los yog spark.
- LPG thiab propane tsis muaj ntxhiab tsw hauv lawv lub xeev ntuj, tab sis cov ntxhiab tsw phem hu ua mercaptan tau ntxiv rau lawv txhawm rau txhawm rau kuaj pom los ntawm tsw.
- LPG thiab propane yog ob qho tib si hnyav dua li huab cua thiab tuaj yeem khaws cia hauv qhov chaw qis, xws li hauv qab daus lossis cellars.
- LPG thiab propane muaj lub zog ntau dua li cov pa roj carbon monoxide thiab yog li ua tau zoo dua rau cua sov thiab ua noj.
- LPG thiab propane yog ob qho tib si khaws cia hauv cov thawv ntim, xws li cov tso tsheb hlau luam lossis lub tog raj kheej, kom lawv nyob hauv lawv cov kua dej.
** Ntau lawm
LPG yog tsim los ntawm cov txheej txheem hu ua refining, uas koom nrog kev sib cais ntawm cov roj crude rau hauv ntau yam khoom, xws li roj av, diesel, kerosene, thiab LPG. Natural gas processing yog lwm txoj hauv kev tsim LPG, uas cov roj ntuj tau muab rho tawm los ntawm cov dej hauv av thiab tom qab ntawd muab cais rau hauv nws cov khoom siv ntau yam kev siv.
Propane yog tsim los ntawm cov khoom lag luam ntawm ob qho tib si roj av refining thiab natural gas processing. Nyob rau hauv cov roj crude refining, propane yog cais los ntawm lwm cov hydrocarbons los ntawm fractional distillation. Hauv kev ua cov pa roj carbon monoxide, propane raug cais tawm ntawm methane, ethane, thiab lwm yam gases los ntawm cov txheej txheem hu ua absorption.
** Siv
LPG thiab propane yog siv rau ntau lub hom phiaj, nrog rau cov cua sov hauv tsev, ua noj ua haus, kev thauj mus los, thiab kev lag luam. Nov yog qee qhov kev siv tseem ceeb ntawm LPG thiab propane:
- Cov cua sov hauv tsev: LPG thiab propane feem ntau yog siv los ua roj rau boilers, furnaces, thiab dej rhaub hauv cov chaw nyob.
- Ua noj ua haus: LPG thiab propane feem ntau yog siv los ua noj rau hauv qhov cub thiab qhov cub hauv tsev thiab khw noj mov.
- Kev thauj mus los: LPG thiab propane tuaj yeem siv los ua lwm yam roj rau tsheb, suav nrog tsheb, tsheb thauj khoom, thiab tsheb npav.
- Cov txheej txheem kev lag luam: LPG thiab propane yog siv rau ntau yam kev lag luam, xws li hlau fabrication, iav ntau lawm, thiab kev tsim khoom yas.
** Kev ceev faj txog kev nyab xeeb
Ib yam li cov roj lossis tshuaj lom neeg, LPG thiab propane ua rau muaj kev pheej hmoo ntawm kev nyab xeeb yog tias tsis ua haujlwm raug. Nov yog qee qhov kev ceev faj txog kev nyab xeeb uas yuav tsum tau ua raws thaum siv LPG thiab propane:
- Nco ntsoov khaws LPG thiab propane tso tsheb hlau luam rau hauv qhov chaw muaj cua zoo kom tsis txhob muaj cov pa paug.
- Tsuas yog siv LPG thiab propane cov khoom siv uas tsim thiab sim rau cov roj ntawd.
- Tsis txhob cuam tshuam nrog LPG thiab propane tso tsheb hlau luam lossis cov khoom siv hauv txhua txoj kev, vim qhov no tuaj yeem ua rau tawg lossis tawg.
- Ib txwm ua raws li cov lus qhia rau kev siv thiab khaws cia los ntawm cov chaw tsim khoom.
- Muaj LPG thiab propane tanks thiab cov khoom siv tshuaj xyuas tsis tu ncua los ntawm tus kws tshaj lij.
** Lus xaus
Hauv kev xaus, thaum LPG thiab propane tsis zoo ib yam, propane yog ib qho tseem ceeb ntawm LPG. Ob lub roj muaj cov khoom zoo sib xws thiab kev siv, tab sis lawv kuj tuaj yeem pom qee qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, kev tsim khoom, thiab kev ceev faj txog kev nyab xeeb. Los ntawm kev nkag siab txog qhov sib txawv no, cov neeg siv ntawm LPG thiab propane tuaj yeem ua kom ntseeg tau tias lawv siv cov roj no kom nyab xeeb thiab ua tau zoo.
