Ikhwalithi ephezulu yaseChina Fuel Gas Conditioning Skid Exporters - Ukushushuluza kwegesi yomsila - Rongteng

Incazelo

I-skid yokwelapha igesi yomsila wegesi yemvelo isetshenziswa ikakhulukazi ukubhekana negesi yomsila wensimbi yokutakula isulfure, kanye negesi engcolile ye-liquid sulfur pool kanye ne-TEG yegesi yemfucuza yomshini wokukhipha amanzi emzimbeni wethuluzi lokubuyisela isibabule.
Umthamo wokuklama nokucubungula we-skid ufaniswe nedivayisi yokubuyisela isibabule kanye nedivayisi yokukhipha amanzi emzimbeni.
I-skid yokwelapha igesi yomsila wemvelo ingahlukaniswa izigaba ezine

1. Ukunciphisa kanye nenqubo yokumuncwa
Isimiso sokunciphisa kanye nenqubo yokumuncwa ukuthi igesi yomsila i-hydrogenated, izingxenye ezinesulfure egesi yomsila zincishiswa zibe yi-H2S, i-H2S ekhiqizwayo imuncwa ngokukhetha indlela ye-amine, futhi ekugcineni ukuvuselelwa kabusha noma igesi ikhishwa ukuze kufakwe iyunithi ye-Claus yokusabela okujikelezayo. Inqubo ye-Hydrogenation inokutshalwa kwezimali okuphezulu kanye nezindleko eziphezulu zokusebenza, kodwa isetshenziswa kakhulu emazweni nasezifundeni ezinezidingo eziphakeme zokuvikelwa kwemvelo ngoba ingathola isivuno esiphezulu sesibabule, esingaphezu kuka-99.8%.

2 Inqubo yokumuncwa kwe-oxidation
Indlela yokumunca i-oxidation iyindlela eqala ngokukhipha i-sulfide kugesi yomsila iye ku-SO2, bese imunca i-SO2 ngesisombululo (noma i-solvent), futhi ekugcineni iyibuyisele esimweni se-sulfate, i-sulfide ne-SO2.
Kunezindlela eziningi zalolu hlobo, iningi lazo ezisetshenziselwa ukukhishwa kwegesi e-flue noma ekwelapheni igesi yomsila evela ku-smelters nezitshalo ze-sulfuric acid, futhi indlela ka-Wellman Lord isetshenziselwa ukwelashwa kwe-Claus tail gas.

3. Inqubo yokushisa ephansi yeClaus
Izinga lokushisa eliphansi likaClaus ubuchwepheshe libonakala ngokusabela kukaClaus ngaphansi kwephuzu lamazolo esibabule, ngakho-ke kubizwa nangokuthi inqubo yokutholwa kwesulfure. Ukusabela kukaClaus kuyinqubo eqinile yokusabela kwe-exothermic. Ngakho-ke, izinga lokushisa eliphansi livumela ukushintsha kokulingana kuya ekuqondisweni kwesizukulwane sesulfure, okungathuthukisa ukubuyiswa kwesibabule. Ngokobudlelwano phakathi kokusabela kukaClaus neyunithi, inqubo yezinga lokushisa eliphansi likaClaus ingahlukaniswa ngenqubo ezimele yokushisa ephansi kaClaus kanye nenqubo ehlanganisa izinga lokushisa eliphansi likaClaus.

4. Inqubo ye-oxidation yesigaba samanzi
Inqubo ye-oxidation eqondile yesigaba soketshezi iwuhlobo lobuchwepheshe benqubo obuxilisa i-H2S ku-elemental sulphur. Umgomo wale nqubo ukumunca i-H2S egesini yomsila ngesisombululo se-desulfurization, bese uyi-oxidize ukuze kukhiqizwe isulfure eyisisekelo.

Imingcele yezobuchwepheshe

1 SO2 ≤ 400mg/Nm3 (isisekelo esomile, 3vol% O2)
2 Isikhathi sokukhiqiza sonyaka amahora angama-8000
3 Ukusebenza okuvumelana nezimo 50%~120%
