2.3 Chigadziko Chekuomesa Gasi Rekudya
1) Tsananguro yemaitiro
Gasi rechisikigo rakabviswa acid rinopinda mu chikamu chekuomesa gasi rekudya. Mudziyo uyu unoshandisa tekinoroji yekudzikisa gasi kuti uparadzanise nekuchenesa gasi. Tekinoroji yekudzikisa gasi kuti riparadzise gasi iri. Tekinoroji yekudzikisa gasi kuti riparadzise gasi iri inobva pakudhonza mamorekuru egasi ari pamusoro pechinhu chinodhonza (chinhu chine porous solid), uye kudzikisa gasi nechinhu chinodhonza gasi kunoshandiswa. Hunhu hwekuti simba rinosiyana zvichienderana nekupisa nekumanikidzwa kwemudziyo. Kana chinhu chinodhonza gasi chikasarudza kudhonza zvikamu zvakasiyana zvegasi, zvimwe zvikamu zviri mugasi rakasanganiswa zvinodhonza pakupisa kwakaderera uye kumanikidzwa kwakanyanya, uye zvikamu zvisina kudhonza zvinobuda nepachikamu chinodhonza., zvikamu zvinodhonza zvinodhonza pakupisa kwakakwirira uye kumanikidzwa kwakaderera kune tembiricha yakaderera uye kudhonza kwakanyanya, uye nhare dzakawanda dzinodhonza gasi dzinogona kushandiswa kuzadzisa chinangwa chekuparadzanisa gasi nguva dzose.
Chigadziko chekuomesa gasi rekudyisa uye chekubvisa mahydrocarbon akawanda chine ma adsorber matatu ekushandura, rimwe rekushandisa adsorption, rimwe rekushandisa kutonhora, uye rimwe rekushandisa pakugadzirisa kupisa.
Gasi rinobuda kubva muchikamu chekubvisa acid rinopinda pamusoro pe adsorber, uye mushure mekunge hunyoro hwabviswa ne molecular sieve adsorption, rinobuda pasi pe adsorber. Mushure mekupera mvura, gasi rechisikigo rinopinda mu tower removal mercury.
Chigadziko chekuomesa gasi rinodyisa chinoshandisa gasi diki rekudyisa senzira yekufemesa nekugadzirazve zvinhu zvinotonhora. Kana gasi rekudyisa rabuda mushongwe yekudyisa, rinotonhodzwa roparadzaniswa rodzorerwa kunzvimbo inopinzwa gasi rekuomesa riri mumamiriro ekudyisa.
Gasi rekugadzirisa rinotanga rapfuura nemu adsorber inotonhorera kubva kumusoro kusvika pasi, uye gasi rekugadzirisa rinodziiswa kusvika patembiricha yekuvandudza ye180-260 ℃ neheater yekuvandudza, uye rozopinda kubva pasi pe adsorber kuti ritore mvura inonyudzwa ne adsorbent. Gasi rekugadzirisa rinobuda pamusoro pe dryer, uye mushure mekutonhodzwa ne regeneration cooler, rinopinda mu regeneration gas separator, uye mvura iri mairi inoparadzaniswa yodzorerwa kumberi kwe adsorber.
Mushure mekupfuura nepakati pechinhu ichi, mvura iri mugasi rechisikigo rakaoma inosvika ≤1ppm.
Midziyo mikuru ishongwe yekunyungudutsa mvura, hita yekudzoreredza, cooler yegesi yekudzoreredza uye gasi rekuparadzanisa regeneration.
2) Magadzirirwo edhizaini
Feed gasi kugadzira kugona:10×10 4 Nm 3 /d
Kumanikidzwa kwekushanda: 5.2 Mpa.G
Kupisa kweAdsorption: 40 ℃
Kupisa kwekuvandudzwa: 180 ℃ ~260 ℃
Kupisa kunodzoreredza: kupisa mafuta ekutamisa kupisa
Zviri muH2O mugasi rakacheneswa i ≤ 1ppm
2.4 Chigadzirwa chekubvisa mercury negesi inodyisa
1) Tsananguro yemaitiro
Gasi rechisikigo mushure mehydrocarbons isina simba rinotanga kupinda mu adsorber yakasanganiswa nesulfur. Mercury inosangana nesarufa iri pa activated carbon yakasanganiswa nesulfur kuti igadzire mercury sulfide, iyo inonyudzwa pa activated carbon kuti ibudise chinangwa chekubvisa mercury. Huremu hwemercury mugasi rechisikigo rinobuda mu mercury remover hushoma pane 0.01μg/Nm3.
Chinobvisa mercury chinogadziriswa, uye kabhoni yakanyudzwa nesarufa inotsiviwa zvichienderana nemamiriro ekuona.
Gasi rechisikigo risina mercury rinopinda muchikamu chekusefa.
2) Magadzirirwo edhizaini
Feed gasi kugadzira kugona:10×10 4 Nm 3 /d
Kumanikidzwa kwekushanda: 5.0Mpa.G
Kupisa kweAdsorption: 40 ℃
Huremu hweHg mugasi rakacheneswa hunosvika ≤ 0.01μg/Nm 3
3) Kuwanda kwekugadzirisa: 50% ~ 110%.
2.5 Chigadziko cheKusefa kweGasi reKudyisa
1) Tsananguro yemaitiro
Chipenga ichi chine firita, iyo inogona kuchinjwa uye kushandiswa zvichienderana nedata rekudzivirira kuti zvizadzise chinangwa chekusefa molecular sieve ne activated carbon dust.
Mushure mekubviswa kweguruva, zvidimbu zveguruva mugasi rekudya zvinosvika pasi pe10 μm.
Midziyo mikuru iguruva rinopfapfaidza.
Feed gasi kugadzira kugona:10×10 4 Nm 3 /d
2) Magadzirirwo edhizaini
Kumanikidzwa kwekushanda: 5Mpa.G
Huremu hweguruva mugasi rakacheneswa hunosvika ≤ 5μm
