Kugadzirwa kweHydrogen neAmmonia Cracking

Ammonia cracker inoshandiswa kugadzira gasi rinoputika iro rinoumbwa nehydrogen ant nitrogen pa moleshi ye3:1.Iyo inopinza inochenesa gasi rekugadzira kubva pasara ammonia uye unyoro.Zvadaro chikamu chePSA chinoiswa kupatsanura hydrogen kubva kunitrogen sechisarudzo.

Iyo NH3 iri kuuya kubva mumabhodhoro kana kubva mutangi reammonia.Iyo ammonia gasi inofanopiswa mumoto wekupisa uye vaporizer uye yobva yatsemuka muchoto chikuru chevira.Choto chinodziiswa nemagetsi.

Kuparadzaniswa kweammonia gasi NH3 kunoitika pakupisa kwe800 ° C pamberi penickel-based catalyst muchoto chinopisa chemagetsi.
2 NH₃ → N₂+ 3 H₂
Iyo inopisa inopisa inoshandiswa se economizer: nepo gasi rinopisa rinoputika richitonhodzwa pasi, iyo ammonia gasi inotanga kupisa.

Senge sarudzo uye kuitira kudzikisa dova reyakagadzirwa kugadzira gasi mberi, yakakosha yekugadzira gasi yekuchenesa inowanikwa.Uchishandisa tekinoroji yekusefa, dova regasi rinogadzirwa rinogona kudzikiswa kusvika -70 ° C.Maviri adsorber zvikamu zviri kushanda zvakafanana.Imwe iri kushambadza hunyoro uye isina-kutsemuka ammonia kubva pakugadzira gasi nepo imwe yacho ichidziya kuti igadziriswe.Kuyerera kwegasi kunoshandurwa nguva nenguva uye otomatiki.

PSA unit inoshandiswa kubvisa nitrogen uye saka kuchenesa haidrojeni, kana ichidikanwa.Izvi zvinobva pamaitiro emuviri anoita mashandisiro ezvakasiyana adsorption zvimiro zvemagasi akasiyana kupatsanura haidrojeni kubva kunitrogen.Kazhinji mibhedha yakawanda inoiswa kuti ione kuenderera mberi kwekushanda.

Kutsemuka gasi simba: 10 ~ 250 Nm3/h
Hydrogen simba: 5 ~ 150 Nm3/h
