Chidzitiro chekurapa negasi remuswe

Tsananguro

Gasi rechisikigo rinoshandiswa pakurapa gasi rechisikigo rinoshandiswa zvakanyanya kubata gasi remuswe remuchina wekudzoreredza sarufa, pamwe negasi remvura remudziva wesarufa uye gasi reTEG remvura rinobvisa mvura mumuviri wemudziyo wekudzoreredza sarufa.
Kugona kwekugadzira nekugona kwekugadzirisa skid kunoenderana nemudziyo wekudzoreredza sarufa nemudziyo wekubvisa mvura mumuviri.

Gasi rechisikigo rinobvisa gasi rinogona kukamurwa muzvikamu zvina.

1. Maitiro ekuderedza uye kunyudza
Nheyo yekudzikisa nekunyudza mweya ndeyekuti gasi remuswe rive nehydrogenated, zvikamu zvine sarufa mugasi remuswe zvinoderedzwa kuita H2S, H2S inogadzirwa inonyudzwa nenzira yekusarudza nenzira yeamine, uye pakupedzisira gasi rinoburitswa kuti ripinde muClaus unit yekuparadzira mhinduro. Maitiro ehydrogenation ane mari yakawanda yekudyara uye mutengo wakakwira wekushanda, asi anoshandiswa zvakanyanya munyika nenzvimbo dzine zvinodiwa zvakanyanya zvekuchengetedza zvakatipoteredza nekuti anogona kuwana goho resarufa rakawanda, senge anopfuura 99.8%.

2. Maitiro ekunyudza okisijeni
Nzira yekunyudza oxidation inzira inotanga yaita oxidize sulfide mugasi remuswe kuita SO2, yozonyudza SO2 nemushonga (kana solvent), yozopedzisira yaiwana muchimiro che sulfate, sulfide neSO2.
Kune nzira dzakawanda dzerudzi urwu, dzakawanda dzacho dzinoshandiswa pakubvisa sulfur mumhepo kana kugadzirisa gasi remuswe kubva muzvicherwa zvesimbi nemiti yesulfuric acid, uye nzira yeWellman Lord inoshandiswa pakurapa gasi remuswe reClaus.

3. Maitiro eClaus tembiricha yakaderera
Tekinoroji yeClaus inodziya tembiricha yakaderera inozivikanwa neClaus reaction iri pasi pedova resulfur, saka inonziwo sub dew point sulfur recovery process. Claus reaction inzira yakasimba ye exothermic reaction. Naizvozvo, tembiricha yakaderera inobatsira kuti pave nekuenzana kwe equilibrium kuenda kunzira yekuumbwa kwesarufa, izvo zvinogona kuvandudza kudzorerwa kwesarufa. Zvichienderana nehukama huripo pakati peClaus reaction neyuniti, nzira yeClaus inodziya tembiricha yakaderera inogona kukamurwa kuita nzira yakazvimirira yeClaus inodziya tembiricha yakaderera uye nzira yakabatanidzwa yeClaus inodziya tembiricha yakaderera.

4. Maitiro ekuoxidation zvakananga muchikamu chemvura
Maitiro ekuoxidation zvakananga echikamu chemvura (liquid phase direct oxidation process) imhando yetekinoroji yemaitiro inooxidation zvakananga H2S kuita elemental salfa. Chinangwa chemaitiro aya ndechekupinza H2S mugasi rekumashure ne desulfurization solution, wozoioxidation kuti igadzire elemental salfa.

Magadzirirwo ehunyanzvi

1. SO2 ≤ 400mg/Nm3 (yakaoma hwaro, 3vol% O2)
2, Nguva yekugadzira yegore negore maawa 8000
3, Kuchinjika kwekushanda 50% ~ 120%
