Iimpawu zobuchwephesha benkqubo yokuTyalwa kwerhasi ye-Feed kunye ne-Liquefaction kunye nenkqubo yefriji kwinkqubo ye-LNG plant

Inkqubo yokutya irhasi yangaphambili
Indlela yenkqubo ekhethiweyo yenkqubo yokuhamba kweinkqubo yegesi yokutya kwangaphambiliinezi mpawu zilandelayo:
(1) Xa kuthelekiswa nendlela ye-MEA, indlela ye-MDEA ineempawu zokungabi namagwebu amancinci, ukubola okuncinci kunye nokulahleka kwe-amine encinci.
(2) Iyunithi ithatha i-MDEA ye-decarburization emanzi, kwaye akukho kusetyenziswa kwegesi yokuvuselela.
(3) Ipompo ejikelezayo ye-MDEA ithatha i-speed-speed single-stage centrifugal pump, enokuthembeka okuphezulu, ukusetyenziswa kwamandla aphantsi kunye nokugcinwa okuncinci.
(4) I-molecular sieve adsorption ingasetyenziselwa ukuphelelwa ngamanzi emzimbeni, kwaye isenazo iimpawu eziphezulu ze-adsorption naphantsi komphunga ophantsi woxinzelelo oluyinxenye.
(5) Ukusebenzisa i-carbon activated ukususa i-hydrocarbons enzima kunokususa ngokusisiseko i-hydrocarbons enamakha kunye ne-C6 + i-hydrocarbons enzima, ixazulule ngokupheleleyo ingxaki yokushisa okuphantsi kunye nokuthintela, kunye nokuqinisekisa ukusebenza kwexesha elide.
(6) I-Mercury iphendula kunye nesulfure kwi-sulfure efakwe kwikhabhoni esebenzayo ukuvelisa i-mercury sulfide, efakwe kwikhabhoni esebenzayo ukufezekisa injongo yokususwa kwe-mercury.Ukusebenzisa isulfure efakwe kwikhabhoni esebenzayo ukususa imekyuri kunexabiso eliphantsi.
(7) Into yokucoca echanekileyo inokucoca i-molecular sieve kunye nothuli lwekhabhoni olusebenzayo ukuya kwi-5 μm ngaphantsi.

I-Liquefaction kunye nenkqubo yefriji
Indlela yenkqubo ekhethiweyo yei-liquefaction kunye nenkqubo yefrijiyiMRC (i-mixed refrigerant) yomjikelo wefriji yefriji, ebonakala ngoku:
(1) Ukusetyenziswa kwamandla aphantsi.Le ndlela ineyona ndlela iphantsi yokusetyenziswa kwamandla phakathi kweendlela ezisetyenziswa ngokuqhelekileyo zefriji, okwenza ixabiso lemveliso likhuphisane kwiimarike.
(2) Inkqubo yokulinganisa ifriji ixhomekeke ngokuzimeleyo kwinkqubo yoxinzelelo olujikelezayo.Ngethuba lokusebenza, inkqubo yokulinganisa iphinda izalise i-friji kwi-circulating system compression system ukuze kugcinwe imeko ezinzileyo yokusebenza kwenkqubo yoxinzelelo olujikelezayo;Emva kokuba iyunithi ivaliwe, inkqubo yokulinganisa inokugcina ifriji ukusuka kwindawo ephezulu yoxinzelelo lwenkqubo yoxinzelelo ngaphandle kokukhupha ifriji.Injongo yokwenza oku: okokuqala, gcina ifriji, kwaye okwesibini, nciphisa ixesha lokuqalisa okulandelayo.Ixesha lokuqalisa leyunithi ye-liquefaction lingaphantsi kweeyure ezi-5.
(3) Umthamo kunye noxinzelelo lwenkqubo yefriji iya kwenziwa ngokufanelekileyo.Emva kokuba iyunithi ivaliwe, ngokuqwalasela ukuba zonke iifriji ziphinde zifudunyezwe kwiqondo lokushisa eliqhelekileyo kunye noxinzelelo olulungeleleneyo, inkqubo isenokuthi iqulethe zonke iifriji, ziqinisekise ukuba zonke iindawo zenkqubo azigxininisi kwaye zikhupha umoya, kwaye zivumele ifriji ukuba ihlale kwindawo. inkqubo ixesha elide.
(4) Zonke iivalvu zeyunithi yokunyibilikisa okuphantsi kobushushu zibekwe ngaphandle kwebhokisi ebandayo kwaye zidityanisiwe ukuze kuncitshiswe iindawo ezivuzayo kunye nokuququzelela ukugcinwa kwevalve.Akukho ludibaniso lweflange kwibhokisi ebandayo ukunciphisa iindawo ezivuzayo ezinokubakho kwibhokisi ebandayo.Ithemometha yamanqaku amaninzi kunye ne-gas probe zilungiselelwe ukujonga ukuvuza okunokwenzeka kwibhokisi ebandayo ngexesha lokwenyani.
(5) Ubuchwephesha obuphezulu busetyenziswa ngokubanzi kuyilo lwebhokisi ebandayo.Isakhelo esipheleleyo, umbhobho kunye nohlalutyo loxinzelelo lwendawo luya kwenziwa ukuze kuqinisekiswe ukuthembeka kwebhokisi elibandayo ukusuka kumgangatho woyilo.Okokuqala, i-3D Design Software Solidworks yobuchwephesha isetyenziselwa ukuseka imodeli ye-3D yesakhelo sebhokisi ebandayo kunye nezixhobo zombhobho;Emva koko, i-cosmos isetyenziselwa ukuhlalutya uxinzelelo lwesakhelo;Ukuze kuhlangatyezwane noyilo oluguquguqukayo lombhobho wobushushu obuphantsi, isoftware yohlalutyo loxinzelelo lombhobho we-CAESAR II isetyenziselwa uhlalutyo loxinzelelo lwepayipi;Xa uhlangabezana nengxaki yokuvula umbhobho okanye ukuvulwa okukhulu, ukwenzela ukuba kuqinisekiswe ukuba uxinzelelo ekuvuleni luphakathi koluhlu oluvumelekileyo oluchazwe kumgangatho wesizwe, isofthiwe ye-ANSYS iya kusetyenziselwa uhlalutyo loxinzelelo lwendawo.Jonga iSahluko se-14 ngeenkcukacha.
