4. Normal Operation Condition
Feedstock: synthesis gasi, gasi remunda wemafuta, gasi rechisikigo, gasi remarasha. Inogona kubata gasi rukova neinorganic sulfur yakakwira
se23g/m3 ine dhigirii rekuchenesa rinogutsa. Inogona zvakare kuchenesa gasi rukova neinosvika 20mg/m3 yezvakareruka zvakadaro
organic sulfur seCOS kusvika pasi pe0.1ppm.
5.Loading
Kutakura kudzika: Yakakwirira L / D (min3) inokurudzirwa. Kugadziriswa kwemaactor maviri munhevedzano kunogona kuvandudza kushandiswa
kunyatsoshanda kweiyo adsorbent.
Loading process:
(1) Chenesa reactor isati yarodha;
(2) Isa magidhi maviri asina tsvina ane diki mesh size pane adsorbent;
(3)Takura 100mm layer ye Φ10—20mm refractory spheres pamagetsi asina tsvina;
(4)Ona adsorbent kubvisa huruva;
(5)Shandisa chishandiso chakakosha kuve nechokwadi chekugovera adsorbent pamubhedha;
(6)Ongorora kufanana kwemubhedha panguva yekurodha. Kana mukati-reactor oparesheni ichidikanwa, ndiro yehuni inofanira kuiswa pane adsorbent kuti mushandisi amire pairi.
(7)Isa Grid isina tsvina ine diki mesh size pane adsorbent uye 100mm layer ye Φ20-30mm refractory spheres pamusoro pemubhedha we adsorbent kudzivirira kupinda kweiyo adsorbent uye kuve nechokwadi.
kunyange kugovera gasi rwizi.
6.Kutanga-up
(1) Tsiva hurongwa ne nitrogen kana mamwe magasi anert kusvikira okisijeni mugasi iri pasi pe0.5%;
(2) Preheat rukova rwekudya nenitrogen kana gasi rekudyisa pasi penzvimbo kana kumanikidzwa kwakakwirira;
(3)Kupisa kumhanya: 50°C/h kubva mukamuri tembiricha kusvika 150°C (nenitrogen); 150°C kwe2 h (kana kudziyisa svikiro iri
inochinjirwa kune gasi rekudyisa), 30°C/h pamusoro pe150°C kusvikira tembiricha inodiwa yawanikwa.
(4) Gadzirisa kudzvinyirira zvishoma nezvishoma kusvikira kumanikidzwa kwekushanda kwawanikwa.
(5) Mushure mekutanga-kupisa uye kukwidziridzwa kukwidziridzwa, sisitimu inofanira kutanga yashandiswa pahafu yemutoro ye8h. Wobva wasimudza iyo
takura zvakadzikama kana oparesheni yadzikama kusvika yakazara-chiyero kushanda.
7.Shut-down
(1) Emergent yekuvhara-pasi gasi (oiri) kupa.
Vhara mavharuvhu ekupinda nekubuda. Chengeta tembiricha uye kudzvanywa. Kana zvichidikanwa, shandisa nitrogen kana hydrogen-nitrogen
gasi kuchengetedza kudzvinyirira kudzivirira kudzvinyirira kwakashata.
(2) Shanduko-pamusoro pe desulfurization adsorbent
Vhara mavharuvhu ekupinda nekubuda. Dzikisa tembiricha zvishoma nezvishoma uye kumanikidza kune ambient mamiriro. Zvadaro sarudza
desulfurization reactor kubva kuhurongwa hwekugadzira. Tsiva reactor nemhepo kusvika oxygen inosvika> 20% yawanikwa. Vhura reactor uye uturure iyo adsorbent.
(3) Equipment kugadzirisa (kugadziridza)
Tarisa maitiro akafanana sezvaratidzwa pamusoro kunze kwekunge kudzvanywa kunofanirwa kudzikiswa pane 0.5MPa/10min uye tembiricha.
zvakadzikiswa zvakasikwa.
Iyo adsorbent isina kutakurwa ichachengetwa muzvikamu zvakasiyana. Ongorora sampuli dzakatorwa kubva pane yega yega kuti uone
chimiro uye hupenyu hwebasa hwe adsorbent.
8.Kufambisa uye kuchengetedza
(1)Iyo adsorbent chigadzirwa chakazara mupurasitiki kana simbi mbiya dzine epurasitiki lining kudzivirira hunyoro nemakemikari.
kusvibiswa.
(2) Kudonha, kudhumhana uye kuzununguka kwechisimba kunofanirwa kudzivirirwa panguva yekufambisa kudzivirira kuputika kwemhepo.
adsorbent.
(3) Iyo adsorbent chigadzirwa chinofanira kudzivirirwa kubva pakusangana nemakemikari panguva yekufambisa uye kuchengetedza.
(4) Chigadzirwa chacho chinogona kuchengetwa kwemakore 3-5 pasina kuora kwezvivakwa zvayo kana zvakasimbiswa zvakakodzera.
Kuti uwane rumwe ruzivo nezve zvigadzirwa zvedu, ndapota usazeza kundibata.
