Sesimba repamusoro-soro, rinoshanda, uye rakachena rakachena uye kemikari raw material, gasi rechisikigo rine mukana mukuru wekushandisa. Pakati pavo, liquefied natural gas (LNG), ine yakakwira dhigirii rekushambadzira, yatangawo kukwezva kutarisa sekuwedzera kune echinyakare gasi masosi.
Sezvo mapaipi eLNG ari mapaipi ekutakura ane tembiricha yakaderera, LNG inotakurwa nemapaipi inowanzova muchimiro chemvura ine tembiricha yakaderera. Kana kupisa kwekunze kwapinda, inopwa nyore nyore, zvichiita kuti kuyerera kwemvura yechikamu chimwe chete kuchinje kuita kuyerera kwemvura ine gasi-liquid ine zvikamu zviviri, kana kutovhara gasi, zvichikonzera kuwedzera kwekumanikidzwa uye kudzikira kwekuyerera kwemvura muzvikamu zvemapaipi emunharaunda, zvichikanganisa zvakanyanya kutakurwa kwemvura yeLNG. Nokudaro, kupwa kwemvura yeLNG kunofanirwa kudzorwa zvakanyanya. Zvisinei, kupwa kwemvura yeLNG kunogona kudzivirira kupinda kwekupisa kwekunze uye kupwa kwemvura yeLNG, uye kushanda kwayo kunonyanya kuenderana nemhando yekudzivirira yemapaipi eLNG. Naizvozvo, mapaipi eLNG anofanira kutora matanho ekudzivirira kupisa , uye kunaka kwawo hakuzongokanganisi chete kushanda kwekufambisa kweLNG, asiwo kuve nemhedzisiro yakakosha pakushanda kwakajairika kwehurongwa hwese.
LNG pombi insulation mhando
Vacuum insulation: Nheyo yacho ndeyekuita kuti chigadziriso chiite chivharo chakavharwa, uye nzvimbo yemukati inoburitswa kune imwe nhanho yevacuum kuderedza kupisa. Mudzimba LNG sisitimu, ine nguva yakareba yekushandiswa, iri pachena kupisa kwemafuta ekudzivirira uye kuderera kwesimba kudiki. Nekudaro, nekuda kwemutengo wakakwira uye nguva yakareba yekugadzira, inonyanya kushandiswa mumapurojekiti akakosha uye haigone kushandiswa pamwero mukuru.
Stacking insulation: Stacking insulation inzira yechinyakare yekumisikidza, kureva kuti, porous insulation zvinhu zvakaiswa kunze kwepombi, uye kuvharirwa kunowanikwa nekuti maseru anozadzwa neyakajairwa mhepo yekumanikidza (kana mamwe magasi). Iyo thermal insulation effect yakadzikira zvishoma pane yevacuum insulation, asi ine chimiro chakareruka, mutengo wakaderera, uye nyore kushanda nekugadzirisa. Parizvino, mapaipi epamba eLNG anonyanya kushandisa nzira iyi yekuvharisa pombi.
Mumusika wazvino, izvo zviripo zvakaturikidzana zvekudzivirira zvinhu zvinonyanya kushandisa polyurethane uye furo girazi zvinhu zvinoenderana neyakasiyana tembiricha yeLNG. Kuenzaniswa neyechinyakare yekupisa yekudzimisa zvinhu senge polyurethane uye furo girazi, melamine foam ine zvimwe zvakanakira. Melamine foam ine huwandu hwakasiyana hwekupikiswa kwemamiriro ekunze (minus 196 degrees Celsius kusvika 200 degrees Celsius), inochengetedza chimiro chakatsiga chemuviri uye chemakemikari pasi pemamiriro ekunze epamusoro uye akaderera tembiricha, uye inopa yakanakisa thermal conductivity (thermal conductivity coefficient, 0.032 W/ (m*K))) uye kurira kunyura kuita (0.95NRC), gadzira iyo inodzivirira kuchengetedzwa kwepombi LNG, inochengetedza huremu hwemamiriro ekunze.
Mukugadzirwa kweinjiniya yeLNG zviteshi zvezvirimwa, mamiriro chaiwo epurojekiti anofanirwa kunyatsoongororwa, uye yakakodzera kupisa kwemafuta uye inotonhora yekuvharisa zvinhu zvinofanirwa kusarudzwa uye kushandiswa. Zvinonyanya kukosha zvinosanganisira:
- Iyo shoma yakachengeteka yakachengeteka tembiricha yeinotonhora yekuvharisa zvinhu inofanira kunge yakaderera pane yakaderera tembiricha yepakati panguva yekushanda kwakajairika;
- Kuitwa kwekudzivirira moto kwezvinhu zvinotonhora zvekudzivirira kunofanira kusangana nezvinodiwa zvemazuva ano enyika zviyero;
- Isa pamberi pekushandiswa kwezvinhu zvinotonhora zvekudzivirira zvine yakanakisa mvura mhute permeability kuramba kuve nechokwadi kugadzikana kwenguva refu kwekuita kwezvinhu;
- Iyo inotonhora yekudzivirira zvinhu inofanirwa kuve yakanaka pa-saiti yekucheka kana kucheka kugadzirisa kuita, kuvaka kuri nyore, uye kurerutswa pa-saiti yekuisa kuoma;
- Ipa zvakakosha kune zvigadzirwa kana zvigadzirwa zvine yakakwira yakazara mabhenefiti ehupfumi;
- Deredza huwandu hwebasa rekugadzirisa zuva nezuva mushure mekunge iyo yekutonhodza yaiswa mukugadzira uye kugadzirisa kushandiswazve kwezvinhu.
Zvichibva pane zvinodiwa pamusoro apa, foam yemelamine inogona kushandiswa sechinodzivirira kupisa uye chinhu chinochengetedza kutonhora kwemapaipi eLNG, uye foam yemelamine inoita basa rakakosha mukudzivirira kupisa uye kuchengetedzwa kutonhora kwemapaipi eLNG. Foam yeMelamine ipurasitiki inochinjika ye elastomer ine chimiro che network chine mativi matatu. Ichiri kuchengetedza chimiro chakazara chemuviri uye chemakemikari pa minus 196 degrees Celsius, saka ichiri nekupisa kwakanaka pakupisa kwakaderera uye inodzivirira convection yenzvimbo dzemukati nedzekunze. Kufambisa kupisa nemwaranzi, kudzivirira kupisa kwakanyanya (B1, UL94 V0 uye HL-1) uye kudzivirira kupisa (hazvigadzire chero chinhu chisingachinji uye chinodzivirira kupisa), kudzivirira acid nealkali, kudzivirira ngura, kudzivirira kukwegura, huremu hushoma uye kuchinjika kwakaderera kwekupisa, nezvimwewo, uye nekuti foam yemelamine resin ipurasitiki asi isiri fiber, haina guruva, haina halogenated uye haina mahydrocarbon, haidziviriri moto uye/kana simbi dzine chepfu, inonyanya kukodzera nzvimbo dzine zvinodiwa zvakanyanya zvekuchengetedza nharaunda, kuchengetera kutonhora (fekitori yekugadzira mishonga, fekitori yekuchengetedza michero nemiriwo, fekitori yekugadzirisa chikafu, fekitori yekugadzirisa nyama nefekitori yezvinwiwa zvinotonhora) kudziya kunotonhora (thermal and acoustic insulation), kudziya kunotonhora mufiriji/mufiriji (thermal and acoustic insulation), LNG liquefied storage tank cold insulation (thermal and acoustic insulation), LNG liquefied transport car kana Ship cold and thermal insulation (thermal and acoustic insulation).
