Kugadzirwa kwehydrogen muHengzhong negesi yechisikigo kana jenareta yegesi yehydrogen

1. Main parameters emudziyo

1.1 Mamiriro ekugadzira
Zita rezvinhu zvisina kugadzirwa: gasi rechisikigo
Kumanikidzwa kwezvinhu zvisina kubikwa: 0.02mpag (geji yekumanikidza)
Tembiricha yezvinhu zvisina kugadzirwa: tembiricha yekunze
Kuumbwa kwezvinhu zvisina kugadzirwa (Kwenguva pfupi)

1.2 Zvinodiwa zvehunyanzvi zvehydrogen yechigadzirwa
Kukwanisa kugadzira: 235 Nm3 / h (500kg / D)
Kuchena kwehydrogen: H2 ≥ 99.9%
Kushandiswa kwegasi rechisikigo: 110m3 / h (LHV inopfuura 8500Kcal / m3)
Kumanikidzwa kwehydrogen kubuda: ≥ 1.6Mpa
Tembiricha yekubuditsa: ≤ 40 ℃

1.3 Vimbiso yekushanda zvakanaka
Nguva yepakati pakati pekukundikana kwemidziyo yemagetsi maawa 8000
Kuchinjika kwekushanda kwemudziyo: 30 ~ 110%
Hupenyu hwekugadzira michina isingachinji makore gumi nemashanu

1.4 Marongerwo akajairika
Nzvimbo yekurongeka kwemidziyo yekunze ndeye 26mx10m = 260m2

2. Chikamu chekugadzirisa

2.1 Maitiro etekinoroji
Kudzvanywa uye kushandurwa kwegasi rechisikigo
Gasi rechisikigo riri kunze kwemuganho webhatiri rinotanga ramanikidzwa kusvika pa1.6Mpa necompressor, rozodziiswa kusvika pa380 ℃ negasi rekudya preheater muchikamu che convection chefurnace reformer, robva rapinda mu desulfurizer kuti ribvise sarufa mugasi rekudya riri pasi pe0.1ppm. Gasi rekudya rakabviswa sulfuri uye process steam (3.0mpaa) Gadzirisa preheater yegasi rakasanganiswa zvichienderana ne automatic value yeH2O / ∑ C = 3 ~ 4, wobva wapisa zvakare kusvika pa510 ℃, wobva wapinda zvakaenzana mu conversion pipe kubva pa upper gas gathering main pipe ne upper pigtail pip pigtail pip pigtail. Mu catalyst layer, methane inosangana ne steam kuti igadzire CO neH2. Kupisa kunodiwa pakushandura methane kunopihwa nemusanganiswa wemafuta unopiswa pa below burner. Tembiricha yegasi rinoshandurwa kubva mu reformer furnace i850 ℃, uye tembiricha yakakwira inoshandurwa kuita high tembiricha. Gasi remakemikari rinopinda mu tube side ye waste heat boiler kuti rigadzire 3.0mpaa saturated steam. Tembiricha yegasi rekuchinja kubva muboiler yekupisa marara inoderera kusvika 300 ℃, uye gasi rekushandura rinopinda muboiler feed water preheater, conversion gas water cooler uye conversion gas water separator kuti iparadzanise condensate kubva muprocess condensate, uye process gas inotumirwa kuPSA.
Gasi rechisikigo rinosanganiswa negasi rekubvisa kudzvanywa kwesimba rinoita kuti mafuta anyunguduke, uye huwandu hwegasi rinopinda mugasi remafuta rinogadziriswa zvichienderana nekupisa kwegasi panobuda gasi remafuta. Mushure mekugadzirisa kuyerera kwemvura, gasi remafuta rinopinda muchoto chepamusoro kuti ripiswe kuti ripise gasi remafuta.
Mvura yakabviswa munyu inopiswa ne preheater yemvura yakabviswa munyu uye boiler feed water preheater uye inopinda mumhepo inobuda mu flue gas waste boiler uye reforming gas waste boiler.
Kuti mvura yemuboiler iite zvinodiwa, phosphate solution shoma ne deoxidizer zvinofanira kuwedzerwa kuti mvura yemuboiler iwedzere kukura uye ngura. Drum inofanira kuramba ichiburitsa chikamu chemvura yemuboiler kuti idzore huwandu hwese hwemvura yemuboiler yakanyungudika mudrum.

Kudzvanywa kwemhepo inodzvanywa
PSA ine nhare shanu dzekudyisa. Imwe nhare yekudyisa inenge iri mumamiriro ekudyisa chero nguva. Zvinhu zvakaita semethane, kabhoni dioxide uye kabhoni monoxide mugasi rekuchinja zvinogara pamusoro pemudyisa. Hydrogen inounganidzwa kubva pamusoro penhare yekudyisa sezvinhu zvisingadyiwi uye inotumirwa kunze kwemuganhu. Mudyisa wakazadzwa nezvinhu zvisina kuchena unobviswa kubva mumudyisa kuburikidza nedanho rekugadzirisa. Mushure mekuunganidzwa, inotumirwa kuchoto chekugadzirisa semafuta. Matanho ekugadzirisa enhare yekudyisa ane matanho gumi nemaviri: kutanga kudonha kwakafanana, kwechipiri kudonha kwakafanana, kwechitatu kudonha kwakafanana, kuburitsa mberi, kuburitsa shure, kupukuta, kwechitatu kukwira kwakafanana, kwechipiri kukwira kwakafanana, kwekutanga kukwira kwakafanana uye kwekupedzisira kukwira. Mushure mekuvandudzwa, nhare yekudyisa inokwanisa zvakare kurapa gasi rakashandurwa uye kugadzira hydrogen. Nhare shanu dzekudyisa dzinotora nguva yekuita matanho ari pamusoro apa kuti ive nechokwadi chekuti inorapwa nguva dzose. Chinangwa chekushandura gasi uye kuramba uchigadzira hydrogen panguva imwe chete.
