Ukuphelelwa ngamanzi emzimbeni yigesi yendalo: Imigaqo, iindlela, kunye nembono

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.

Iindlela:Kusetyenziswa iindlela ezintathu eziphambili:

1. Ukufunxa (Ukuphelelwa ngamanzi emzimbeni yiGlycol - Indlela Ephambili):Igesi emanzi idibana ne-hygroscopic liquid desiccant, edla ngokuba yiTriethylene Glycol (TEG), kwi-contactor (absorber) tower. Umphunga wamanzi unyibilika kwi-glycol. I-glycol etyebileyo emva koko iphinda ivuselelwe ngokufudumeza ukuze ibilise emanzini ize isetyenziswe kwakhona.
2. Ukufunxwa (Ukuphelelwa ngamanzi emzimbeni yiSolid Desiccant):Igesi idlula kwiibhedi zee-desiccant eziqinileyo ezifana ne-silica gel, i-alumina esebenzayo, okanye ii-molecular seeves. Iimolekyuli zamanzi zinamathela kwindawo enkulu yomphezulu we-desiccant. Isetyenziselwa iimfuno ze-dew point eziphantsi kakhulu okanye ukusetyenziswa koxinzelelo oluphezulu. Iibhedi zivuselelwa kusetyenziswa igesi eshushu.
3. Ukufuma:Igesi iyapholiswa (umz., ngokuyibeka efrijini, ukuyikhulisa, okanye xa idibene Ukufunxwa kwe-TEG kwinkqubo ye-"Coldfinger"), nto leyo ebangela ukuba umphunga wamanzi ujike ube ngamathontsi amanzi aze ahlukane.

Iingenelo:Ukuphelelwa ngamanzi emzimbeni ngokufanelekileyo kuneengenelo ezibalulekileyo:

• Ithintela ukwakheka kwe-Hydrate:Iqinisekisa ukuhamba kwegesi ngaphandle kokuphazamiseka kwimibhobho nakwizixhobo zokucubungula.
• Inciphisa ukugqwala:Inciphisa ukugqwala okubangelwa ngamanzi olwelo kunye neegesi ze-asidi, yandisa ubomi bezixhobo kwaye iphucula ukhuseleko.
• Ihlangabezana neenkcukacha zePipeline:Kubalulekile ukuhlangabezana neemfuno zomxholo wamanzi wesivumelwano sokuhambisa nokuthengisa igesi.
• Ikhusela Iinkqubo Ezisezantsi:Ithintela iingxaki kwizityalo ezibangela ukurhawuzelelwa (umz., Imveliso ye-LNG) apho amanzi aqandisa khona.

Amathemba: Ukuphelelwa ngamanzi emzimbeni yiGlycol Ihlala ingumqeshwa onzima ngenxa yokusebenza kwayo kakuhle kunye nokonga iindleko. Uphuhliso lwexesha elizayo lugxile koku:

• Iinkqubo zeGlycol eziphuculweyo:Ukuphucula ukusebenza kakuhle kokuvuselelwa kwe-TEG (umz., i-Drizo, i-Coldfinger) ukuze kufezekiswe amachaphaza aphantsi omthunzi ngamandla amancinci kunye nokulahleka kwe-glycol.
• IiDesiccants eziphambili:Ukuphuhlisa izihluzo zemolekyuli ezihlala ixesha elide, ezinomthamo ophezulu kunye nezihluzo ezivuselelekayo.
• Itekhnoloji yeMembrane:Uphando luyaqhubeka malunga nee-membranes ezinika amandla aphantsi kwizicelo ezithile.
• Ukuthobela iMithetho yokusingqongileyo:Ukunciphisa ukukhutshwa kwezinto ezikhutshwayo (ii-VOC, i-BTEX) ezivela kwiiyunithi ze-glycol kunye nokusebenzisa kakuhle amandla zezona zinto ziphambili eziqhuba oku.
• Ukwenziwa kwedijithali kunye nokuZenzekelayo:Ukusebenzisa iinkqubo zolawulo eziphambili ukuze kusebenze kakuhle kwaye kugcinwe izinto kwangaphambili.

Ukuphelelwa ngamanzi emzimbeni kusaqhubeka njengenyathelo elibalulekileyo nelitshintshayo ekucutshungulweni kwegesi, elibalulekileyo ekuvelisweni nasekuthuthweni kwegesi yendalo ngokukhuselekileyo, ngokufanelekileyo, nangokuthembekileyo kwihlabathi liphela.
