Ukuguqula Unyango lweGesi: Indlela i-MDEA Desulphurization Skids ezitshintsha ngayo ukususwa kwe-H2S kwizityalo ze-LNG
Izisombululo ezintsha zemodyuli ziyahlangabezana nemfuno ekhulayo yamandla acocekileyo phakathi kwemithetho engqongqo yokusingqongileyo

Ishishini lokucubungula igesi yendalo libona inkqubela phambili ebalulekileyo kwi-molecular sieve desulphurization kunye netekhnoloji yokuphelisa ukungcola, eqhutywa kukwanda kweemfuno zeenkcukacha zamafutha ezicocekileyo kakhulu kunye nokusebenza kakuhle. Izinto ezintsha zakutshanje zigxile ekuphuculeni uzinzo lwe-catalyst kunye nokukwazi ukuhlaziya izixhobo zokuphelisa ukungcola kwegesi yendalo, ngakumbi kwizityalo ze-LNG kunye nokubuyiselwa kwe-NGL kwizicelo zegesi yendalo.

Izisombululo ze-LNG zehlabathi iqalise isityalo se-LNG esisemgangathweni ophezulu eNtshona Ostreliya, esidityaniswe negesi yendalo kunye neenkqubo zonyango oluphambili.

Umgaqo:Igesi yendalo esuka ngqo emthonjeni iqulethe umphunga wamanzi omninzi. Ukuba ayisuswanga, la manzi anokujiya kwimibhobho, enze ii-hydrate (izinto eziqinileyo ezifana nomkhenkce) ezithintela ukuhamba kwamanzi, okanye zibangele ukugqwala xa zidityaniswe neegesi ze-asidi (ezifana ne-CO₂ okanye i-H₂S). Ukuphelelwa ngamanzi emzimbeni kujoliswe ekunciphiseni inqanaba lomphunga wamanzi ngaphantsi kobushushu obuphantsi obulindelweyo bombhobho ukuthintela ezi ngxaki.

Igesi yendalo, "i-bridge fuel" ebalulekileyo, idla ngokuba ne-hydrogen sulfide (H₂S) kunye nee-organic sulfur compounds (mercaptans, COS), ezinobungozi, zirhabaxa, kwaye zivelisa i-SOx eyingozi xa itsha. Ngoko ke kubalulekile ukuba i-desulfurization (i-sweetening).

Indlela yokucocwa kwegesi yendalo iyanda njengoko abaqhubi bejika besiya kwizisombululo ze-modular skid, eziqhutywa yimfuno engxamisekileyo yokusebenza ngendlela eyonga ikhabhoni.

Iimarike ze-LNG zehlabathi ziqhuba amanzi anzima. Nangona amaqondo obushushu ehlobo enyuka kakhulu nto leyo ebangela imfuneko yokupholisa, idatha ye-Kpler ityhila inyani eyoyikisayo: Ukukhula kokuthunyelwa kwe-LNG kwamanye amazwe ngo-2024 kwehle ukuya kwi-0.4% kuphela—isantya esicothayo ukusukela ngo-2015.

Inkqubo yonke yokuqokelela ioyile, igesi yendalo enxulumene nayo, kunye nezinye iimveliso eziveliswa yimithombo yeoyile esasazekileyo, kunye nokuthumela ioyile kunye negesi yendalo esemgangathweni kwiindawo zokucocisa kunye nabasebenzisi begesi yendalo ngokusebenzisa inkqubo efunekayo kunye nokucubungula kokuqala kubizwa ngokuba kukuqokelela kunye nokuthuthwa kweoyile kunye negesi.

Ukujonga phambili, imakethi yokubuyisela igesi evuthayo iya kuzisa amathuba kunye nemingeni engaphezulu.
