Soo saarista Haydaroojin ee Ammonia Cracking

Buskudka ammonia waxa loo isticmaalaa in lagu dhaliyo gaaska dilaaca kaas oo ka kooban nitrogen qudhaanjada hydrogen marka loo eego saamiga mole ee 3:1.Nuuggu wuxuu ka nadiifiyaa gaaska samaysanaya ammonia iyo qoyaan haray.Kadibna cutubka PSA ayaa lagu dabaqayaa si loo kala saaro hydrogen iyo nitrogen sida ikhtiyaari ah.

NH3 waxay ka imanaysaa dhalooyinka ama haanta ammonia.Gaaska ammonia waxaa horay loogu sii kululeeyay kulayl-bedeliyaha iyo uumiga ka dibna dildilaaca qaybta foornada weyn.Foornada waxaa lagu kululeeyaa koronto.

Kala-soocidda gaaska ammonia NH3 waxay ku dhacdaa heerkul ah 800 ° C iyadoo ay jirto kicinta nikel-ku-saleysan foornada kuleylka korontada ku jirta.
2 NH₃ → N₂+ 3 H₂
Kuleyliyaha kuleyliyaha waxaa loo isticmaalaa sida dhaqaaleeye: halka gaaska dilaaca kulul la qaboojiyo, gaaska ammonia waa la sii kululeeyay.

Ikhtiyaar ahaan iyo si loo yareeyo barta sayaxa ee gaaska samaysmaya, gaas-sifeeye gaar ah ayaa diyaar ah.Isticmaalka tignoolajiyada shaandhada molecular, barta sayaxa ee gaasta la dhaliyo waxa lagu dhimi karaa -70°C.Laba qaybood oo adsorber ah ayaa si is barbar socda u shaqaynaya.Mid ayaa qoyaanka iyo ammonia-ka aan dillaacin ka keenaysa gaasta samaynaysa halka kan kalena loo kululeeyo dib-u-soo-noolaynta.Socodka gaaska si joogto ah iyo si toos ah ayaa loo dami doonaa.

Unugga PSA waxaa loo isticmaalaa in laga saaro nitrogen oo sidaas darteed lagu nadiifiyo hydrogen, haddii loo baahdo.Tani waxay ku salaysan tahay hab jidheed kaas oo ka dhigaya isticmaalka sifooyinka kala duwan ee gaasaska kala duwan si loo kala saaro hydrogen iyo nitrogen.Sida caadiga ah dhowr sariirood ayaa la geeyaa si loo xaqiijiyo hawlgalka sii socda.

Awoodda gaaska dillaacsan: 10 ~ 250 Nm3 / saac
Awoodda hydrogen: 5 ~ 150 Nm3 / saac
