Tsananguro pfupi:
Chinhu chinobatsira pakuchinja tembiricha zvishoma:
Kushandiswa
CB-5 neCB-10 zvinoshandiswa pakushandura mukugadzira uye kugadzira hydrogen
Kushandisa marasha, naphtha, gasi rechisikigo uye gasi remunda wemafuta senzvimbo dzekudya, kunyanya kune vashanduri vekuchinja tembiricha yakaderera yeaxial-radial.
Hunhu
Chinobatidza chine zvakanakira zvekushanda patembiricha yakaderera.
Kuwanda kwehuwandu hwakaderera, pamusoro peCopper neZinc zvakakwirira uye simba remainjiniya riri nani.

ZnO desulfurization Catalyst ine mhando yepamusoro uye mutengo wemakwikwi
HL-306 inoshanda pakubvisa magasi anopwanya kana kuti syngas uye kucheneswa kwemagasi ekudya kwemhuka.
Maitiro ekugadzira organic. Yakakodzera kushandiswa pakupisa kwepamusoro (350–408°C) uye pasi (150–210°c).
Inogona kushandura sarufa iri nyore asi ichitora sarufa isingasanganisike mumhepo.
Maitiro ekubvisa sulfurization ndeaya anotevera:
(1) Kuita kwe zinc oxide ne hydrogen sulfide H2S+ZnO=ZnS+H2O
(2) Kuita kwe zinc oxide nemamwe macompounds ari nyore e sarufa nenzira mbiri dzinogoneka.

| Kubudirira kwesarufa kugona, huwandu% | ≥28(350°C)≥15(220°C)≥10(200°C) |
4. Mamiriro Ekushanda Akajairika
Zvekudya: gasi rekugadzira, gasi remumunda wemafuta, gasi rechisikigo, gasi remarasha. Rinogona kurapa rwizi rwegasi nesarufa isina organic yakawanda
ine 23g/m3 ine mwero wekucheneswa unogutsa. Inogona zvakare kuchenesa rwizi rwegasi nemafuta anosvika 20mg/m3 ari nyore kudaro.
sarufa yeorganic seCOS kusvika pasi pe0.1ppm.
5.Kurodha
Kudzika kwekuisa zvinhu: Kukura kweL/D (min3) kunokurudzirwa. Kugadziriswa kwema reactor maviri akatevedzana kunogona kuvandudza mashandisirwo awo
kushanda zvakanaka kwe adsorbent.
Maitiro ekurodha:
(1) Chenesa reactor usati waisa zvinhu;
(2) Isa magridi maviri asina ngura ane saizi diki pane adsorbent;
(3) Isa 100mm layer ye Φ10—20mm refractory spheres pamusoro pe grids dzisina ngura;
(4) Vhara chinodzivirira kuti chibvise guruva;
(5) Shandisa chishandiso chakakosha kuti uve nechokwadi chekuti adsorbent iri pamubhedha inopararira zvakaenzana;
(6) Ongorora kufanana kwemubhedha panguva yekurodha. Kana zvichidikanwa kushanda mukati me reactor, ndiro yehuni inofanira kuiswa pa adsorbent kuti mushandisi amire pairi.
(7) Isa grid isina tsvina ine saizi diki yemesh pane adsorbent uye 100mm layer ye Φ20—30mm refractory spheres pamusoro pemubhedha we adsorbent kuitira kudzivirira kuvharwa kwe adsorbent uye chengetedza
kugoverwa kwemvura inoyerera negasi zvakaenzana.
6. Kutanga-kambani
(1) Tsiva sisitimu nenitrogen kana mamwe magasi asina simba kusvika huwandu hweokisijeni mugasi hwava pasi pe0.5%;
(2) Pisai rwizi rwekudya nenitrogen kana gasi rekudyisa kana muchimanikidzwa kana muchina wakakwira;
(3) Kumhanya kwekupisa: 50°C/awa kubva patembiricha yemumba kusvika 150°C (ine nitrogen); 150°C kwemaawa maviri (kana nzvimbo yekupisa iri
yakachinjirwa kugasi rekudyisa), 30°C/awa pamusoro pe150°C kusvika tembiricha inodiwa yasvika.
(4) Gadzirisa kumanikidzwa zvishoma nezvishoma kusvika kumanikidzwa kwekushanda kwasvika.
(5) Mushure mekudziya uye kukwidziridzwa kwesimba, sisitimu inofanira kutanga yatanga kushanda nehafu yemutoro kwemaawa masere. Wobva wasimudza
mutoro unorema zvishoma nezvishoma kana basa rava kugadzikana kusvika rapera.
7. Kudzima
(1) Kuwanikwa kwegasi (mafuta) rinodzima nekukurumidza.
Vhara mavharuvhu ekupinda nekubuditsa. Chengetedza tembiricha nekumanikidzwa. Kana zvichidikanwa, shandisa nitrogen kana hydrogen-nitrogen
gasi kuti rirambe richimanikidza kudzivirira kumanikidzwa kusina kunaka.
(2) Kuchinja kwe desulfurization absorbent
Vhara mavharuvhu ekupinda nekubuditsa. Deredza tembiricha nekumanikidzwa zvishoma nezvishoma kuti zvienderane nemamiriro ekunze. Wobva wabvisa
reactor yekubvisa sulfurization kubva mugadziriro yekugadzira. Tsiva reactor nemhepo kusvika huwandu hweokisijeni hunosvika >20%. Vhura reactor woburitsa adsorbent.
(3) Kugadzirisa michina (kugadzirisa)
Tevedzera maitiro akafanana neakaratidzwa pamusoro apa kunze kwekuti kumanikidzwa kunofanira kudzikiswa pa 0.5MPa/10min uye tembiricha.
kudzikiswa zvakasikwa.
Chinhu chinosimudzira mvura chisina kusunganidzwa chinofanira kuchengetwa muzvikamu zvakasiyana. Ongorora mienzaniso inotorwa kubva muchikamu chimwe nechimwe kuti uone
chinzvimbo uye hupenyu hwebasa remubatsiri.
8. Kutakura nekuchengetedza
(1) Chigadzirwa chinonyungudutsa mvura chinoiswa mupurasitiki kana simbi ine purasitiki kudzivirira hunyoro nemakemikari.
kusvibiswa.
(2) Kudonha, kuroverana uye kudedera zvine simba zvinofanirwa kudzivirirwa panguva yekufambisa kudzivirira kupwanyika kwemvura.
adsorbent.
(3) Chigadzirwa chinonyungudutsa chinofanira kudzivirirwa kuti chisabatane nemakemikari panguva yekutakura nekuchengetera.
(4) Chigadzirwa ichi chinogona kuchengetwa kwemakore 3-5 pasina kuora kwehunhu hwacho kana chakavharwa zvakanaka.
Kuti muwane rumwe ruzivo nezvezvigadzirwa zvedu, musazeza kundibata.
