Ukuguqula Ukwelashwa Kwegesi: Indlela I-MDEA Desulphurization Skids Eguqula Ngayo Ukususwa Kwe-H2S Ezitshalweni Ze-LNG
Izixazululo ezintsha ze-modular zihlangabezana nesidingo esikhulayo samandla ahlanzekile phakathi kwemithetho eqinile yezemvelo

Imboni yokucubungula igesi yemvelo ibona intuthuko ebalulekile kubuchwepheshe bokususa i-sulphurization yesihlungo sama-molecule kanye nokuphelelwa amanzi emzimbeni, okuqhutshwa ukwanda kwezidingo zemininingwane kaphethiloli ehlanzekile kakhulu kanye nokusebenza kahle. Izinto ezintsha zakamuva zigxile ekuthuthukiseni ukuzinza kwe-catalyst kanye namakhono okuvuselela imishini yokuphelelwa amanzi emzimbeni wegesi yemvelo, ikakhulukazi izitshalo ze-LNG kanye nokululama kwe-NGL ekusetshenzisweni kwegesi yemvelo.

Izixazululo ze-LNG Zomhlaba Wonke iqalise isitshalo se-LNG esisezingeni eliphezulu eNtshonalanga Australia, esihlanganiswe negesi yemvelo kanye nezinhlelo ezibalulekile zokwelashwa kwangaphambi kwesikhathi.

Isimiso:Igesi yemvelo isuka ngqo emthonjeni iqukethe umhwamuko wamanzi omningi. Uma ingasuswa, la manzi angajiya emipayipini, akhe ama-hydrate (izinto eziqinile ezifana neqhwa) ezivimba ukugeleza, noma zibangele ukugqwala uma zihlanganiswa namagesi e-asidi (njenge-CO₂ noma i-H₂S). Ukuphelelwa amanzi emzimbeni kuhlose ukunciphisa iphuzu lamazolo amanzi ngaphansi kwezinga lokushisa eliphansi kakhulu lomzila wepayipi ukuze kuvinjelwe lezi zinkinga.

Igesi yemvelo, "uphethiloli webhuloho" obalulekile, ivame ukuqukatha i-hydrogen sulfide (H₂S) kanye nama-organic sulfur compounds (mercaptans, COS), anobuthi, agqwala, futhi akhiqiza i-SOx eyingozi lapho isha. Ngakho-ke kubalulekile ukususa i-sulfurization (ukwenza kube mnandi).

Isimo sokuhlanzwa kwegesi yemvelo siyashesha njengoba abaqhubi bephendukela ezixazululweni ze-modular skid, eziqhutshwa yisidingo esiphuthumayo semisebenzi egcina ikhabhoni kahle.

Izimakethe ze-LNG zomhlaba wonke zidlula emanzini anolaka. Naphezu kokuphakama kwamazinga okushisa ehlobo okudala isidingo sokupholisa esiqopha umlando, idatha ye-Kpler yembula iqiniso elimangazayo: Ukukhula kokuthunyelwa kwe-LNG ngo-2024 kwehle kwaya ku-0.4% kuphela—isivinini esihamba kancane kusukela ngo-2015.

Inqubo yonke yokuqoqa uwoyela, igesi yemvelo ehlobene nayo, neminye imikhiqizo ekhiqizwa yimithombo kawoyela ehlakazekile, kanye nokuthumela uwoyela negesi yemvelo efanelekile ezindaweni zokuhluza kanye nabasebenzisi begesi yemvelo ngokusebenzisa ukucubungula okudingekayo kanye nokucubungula kokuqala ibizwa ngokuthi ukuqoqa nokuthutha uwoyela negesi

Uma sibheka phambili, imakethe yokubuyisa igesi evuthayo izoletha amathuba nezinselele ezengeziwe.
