Ukususwa kwegesi yendalo kunye nokuphela kwamanzi emzimbeni kwigesi yendalo kuqhuba i-Wave elandelayo yokukhula kwiNkqubo yeGesi yendalo yehlabathi
Njengoko ishishini lamandla lehlabathi liqhubeka nokulinganisela ukhuseleko lwamandla, ukufikeleleka, kunye nokuzinza, imfuno yokusebenza ngokufanelekileyo ukucubungula igesi yendalo ubuchwepheshe bukhula ngokukhawuleza. Uphuhliso lwakutshanje kulo lonke elaseAsia, eMbindi Mpuma, naseMntla Melika lubonisa ukuba utyalo-mali kwi Ukususwa kwe-sulfurization yegesi yendalo, Ukuphelelwa ngamanzi kwigesi yendalo, kwaye idityanisiwe unyango lwegesi yendalo Izakhiwo ziyakhawuleza, nto leyo edala amathuba abalulekileyo kubaboneleli ngetekhnoloji kunye nabakhi be-EPC.
Kwiinyanga zakutshanje, iiprojekthi ezininzi ezinkulu zophuhliso lwegesi zibhengeze izicwangciso zokwandisa izakhiwo zokucubungula igesi ezisezantsi, kuquka nezitsha Isityalo se-LNG utyalo-mali kunye nokuphuculwa kweziseko zophuhliso zonyango lwegesi ezikhoyo. Ezi projekthi zibonisa ukugxila okukhulayo kushishino ekuphuculeni umgangatho wegesi, ukunciphisa ukukhutshwa komoya, kunye nokwandisa ixabiso lemithombo ye-hydrocarbon.
Enye yezona ndlela zibalulekileyo ezibumba imarike kukwanda kwemfuneko yegesi yendalo ecocekileyo. Imijelo yegesi yendalo idla ngokuba ne-hydrogen sulfide (H₂S), i-carbon dioxide (CO₂), umphunga wamanzi, kunye nezinye izinto ezingcolisayo ekufuneka zisuswe ngaphambi kokuba zithuthwe okanye zinyibilike.
Ukususwa kwe-sulfurization yegesi yendalo idlala indima ebalulekileyo ekususeni iikhompawundi zesalfure ezinokubangela ukugqwala, imiba yokuthobela imiqathango yokusingqongileyo, kunye nokungasebenzi kakuhle kokusebenza. Kwangaxeshanye, Ukuphelelwa ngamanzi kwigesi yendalo iqinisekisa ukuba iinkcukacha zemibhobho ziyafezekiswa ngelixa ithintela ukwakheka kwamanzi ngexesha lokuthuthwa nokugcinwa.
Njengoko imfuno ye-LNG yehlabathi iqhubeka ikhula, abaqhubi bagxininisa ngakumbi kwiinkqubo zangaphambi konyango ezithembekileyo. Nokuba zibonelela ngenethiwekhi yegesi yasekhaya okanye zondla inkampani ejolise ekuthumeleni ngaphandle igesi. Isityalo se-LNG, ukucocwa kwegesi ngokufanelekileyo kube yinto ephambili kwimpumelelo yeprojekthi.
Izibhengezo zakutshanje zoshishino zibonise ukuqhubela phambili okukhulu kutyalo-mali kwiziseko zophuhliso lwegesi yendalo. Amazwe aliqela andisa amandla okuthumela ngaphandle i-LNG ngelixa ngaxeshanye ephuhlisa iinkqubo ezintsha zokuqokelela nokucubungula igesi. Abahlalutyi beli shishini baphawule ukwanda kwenkcitho kwi-integrated unyango lwegesi yendalo izakhiwo ezikwaziyo ukudibanisa ukususwa kwegesi ye-asidi, ukuphelelwa ngamanzi emzimbeni, ukubuyiswa kwesalfure, kunye nokubuyiswa kwe-hydrocarbon kwikhonkco elinye lokucubungula.
Enye indlela ephawulekayo kukwamkelwa okwandayo kweenkqubo eziphambili Isityalo sokubuyisela i-NGL ubuchwepheshe. Ulwelo lweGesi yendalo (ii-NGL), kuquka i-ethane, i-propane, i-butane, kunye nepetroli yendalo, zimele imithombo yengeniso exabisekileyo enokuphucula kakhulu uqoqosho lweprojekthi. Njengoko iinkampani zamandla zifuna ukwandisa inzuzo yeeasethi, utyalo-mali kwiinkqubo zokukhupha i-NGL ezisebenzayo luyaqhubeka nokukhula.
Okwangoku, ukubuyiselwa kweoyile ekhanyayo ubuchwepheshe bufumana ingqalelo kwiiprojekthi ezinxulumene nokucubungula igesi. Ngokufumana ii-condensates kunye nee-hydrocarbons ezixabisekileyo kwimithombo yegesi, abaqhubi banokuphucula ukusetyenziswa kwezixhobo ngokubanzi ngelixa bevelisa ixabiso elongezelelweyo lemveliso.
Sijonge phambili, sikholelwa ukuba ikamva leshishini liza kuchazwa zizisombululo zokucubungula ezidibeneyo nezikrelekrele. Indlela yendabuko yokunyanga igesi ngeeyunithi ezahlukeneyo itshintsha kancinci kancinci iye kwizixhobo eziphucukileyo ezidibanisa Ukususwa kwe-sulfurization yegesi yendalo, Ukuphelelwa ngamanzi kwigesi yendalo, Isityalo sokubuyisela i-NGL imisebenzi, kunye neenkqubo zokuzinzisa i-condensate.
Ukubeka esweni ngedijithali, ukwenza izinto ngokuzenzekelayo, kunye nezixhobo ezisebenzisa amandla ngendlela eyongayo kulindeleke ukuba zibe ziimpawu eziqhelekileyo zezityalo zokucubungula igesi zesizukulwana esilandelayo. Iinkampani ezinokubonelela ngeenkonzo ezipheleleyo ukucubungula igesi yendalo Izisombululo ezineendleko zokusebenza eziphantsi kunye namazinga aphezulu okubuyisela ziya kuba kwindawo engcono yokufumana isabelo semarike.
Ngaphezu koko, njengoko uqoqosho olusakhulayo luqhubeka nokwandisa iziseko zalo zamandla, imfuno yezixhobo ezisetyenziswa ngeendlela ezahlukeneyo nezinokwandiswa unyango lwegesi yendalo iinkqubo kulindeleke ukuba zinyuke kakhulu. Le ndlela ibonakala ngakumbi kwimimandla ephuhlisa iiprojekthi ezintsha zokuthumela ngaphandle i-LNG kunye nothungelwano lokuthuthwa kwegesi oluwela imida.
