Nhanganyaya

MDEA yakasikwa gasi desulphurization (desulfurization) skid, inonziwo MDEA sweeting skid uye gasi chaiyo desulfurization unit, chinhu chakakosha mukuchenesa gasi rechisikigo kana gasi remusikirwo mamiriro.

MDEA yakasikwa gasi desulfurization unit inogara yakagamuchirwa kana kabhoni sulfur yegasi rekudya yakakwira, uye kana kusarudza kubviswa kweH.₂S inodiwa kuti uwane acid gasi inokodzera Claus plant processing, uye mamwe mamiriro anogona kusarudzwa kubvisa H₂S; Pakubvisa H₂S uye kubvisa huwandu hwakawanda hweCO₂, MDEA inogona kushandiswa seyakasanganiswa amine nzira;

Parizvino, iyo huru desulfurization tekinoroji inoshandiswa mukugadzirwa kwemaindasitiri kumba nekune dzimwe nyika ndeiyi: yakaoma (yemuviri) desulfurization, biological desulfurization uye wet desulfurization.

Wet desulfurization inosanganisira absorption nzira uye wet oxidation nzira. Chemical absorption nzira, inomiririrwa nedoro amine absorption, yakashandiswa zvakanyanya muindasitiri. Hydrogen sulfide mugasi inoendeswa kune yemvura chikamu kuti ichenese gasi.

Desulfurization tekinoroji

Biological desulfurization tekinoroji, mumamiriro eiyo micro oxygen, inogona kushandura hydrogen sulfide kuita elemental sulfur, asi tekinoroji yebiological desulfurization haina kukura parizvino.

Dry desulfurization tekinoroji inosanganisira iron oxide nzira, activated carbon method, molecular sieve method, ion exchange method, membrane separation method, biochemical method, etc. parizvino, yakaoma PSA tekinoroji ndiyo inonyanya kushandiswa mukurapwa kwegasi gasi desulfurization diki-diki muindasitiri, iyo inodzorwa zvizere nekombuta, otomatiki, uye otomatiki kubviswa kwechikanganiso shongwe-yakachengeteka kwenguva yakareba.

desulfurization nzira

Amorphous iron hydroxide (dry process). Zvimiro: ine hunhu hwepamusoro desulfurization chaiyo, yakakwira sarufa kugona, simba rakanaka uye isina kutarisirwa. Inoshandiswa zvakanyanya mukubviswa kwehydrogen sulfide mugasi rechisikigo, gasi rekugadzira, biogas, marasha gasi, coalbed methane uye zvakasiyana-siyana zvemakemikari ane sulfur-ine zvinhu; Iyo amorphous hydroxyl oxidation desulfurization ndeye reaction desulfurization, isingakwanise kudzora kudzika kwedesulfurization. Iyo yakanaka desulfurization maitiro. Nekuzara kwe desulfurizer uye kupinda kwe desulfurization tower, iyo desulfurization mhedzisiro ichaderera zvakanyanya, uye zvirimo muhydrogen sulfide mugasi rakacheneswa rinokwira zvakanyanya, saka zvakakosha kutsiva desulfurizer nenguva.
