Kuenzanisa uye kusarudzwa kwetekinoroji yemaitiro
Maitiro ekunyungudutsa gasi rechisikigo anosanganisira kucheneswa kwegasi risina kubikwa, kunyungudutsa (kana kuti LNG liquefaction plant), kudzvanywa kwekutenderera kwemufiriji, kuchengetwa kwezvigadzirwa, kurodha uye sisitimu yekubatsira, nezvimwewo. Maitiro makuru anosanganisira kucheneswa kwegasi risina kubikwa uye kunyungudutsa gasi rakacheneswa.
Kusarudzwa kwemaitiro ekuchenesa gasi rechisikigo
Segasi risina kubikwa, gasi rechisikigo rinofanira kucheneswa zvakakwana risati ranyungudutswa. Izvi zvinoreva kubvisa gasi rine acid, mvura netsvina mugasi rine chikafu, zvakaita seH2S, CO2, H2O, Hg uye aromatic hydrocarbons, kuitira kudzivirira kuvharika nekuora kwemidziyo nemapaipi nekuda kwechando patembiricha yakaderera. Tafura 5.1-1 inonyora mwero wekugadzirisa usati watanga uye huwandu hwakanyanya hwetsvina yegasi rine chikafu mufekitori yeLNG.
Hunhu hwakanyanya hwekusvibiswa hunobvumidzwa hwegasi reLNG feed
| Kusachena | Muganho wezviri mukati | Hwaro |
| H2O | 1ppmV | A (zvinotenderwa kudarika muganho wekunyungudika pasina kuganhurira goho) |
| CO2 | 50～100ppmV | B (muganho wekunyungudika) |
| H2S | ＜4ppmV | C (zvinodiwa zvehunyanzvi zvechigadzirwa) |
| Zvose zviri mu sarufa | 10～50mg/Nm3 | C |
| Hg | ＜0.01μg/Nm3 | A |
| Mahydrocarbon anonhuhwirira | ≤10ppmV | A kana B |
| Huwandu hwehydrocarbon ye naphthenic | ≤10ppmV | A kana B |
Zvichienderana nedata regasi rekudyisa, huwandu hwemvura mugasi rekudyisa hunodarika mwero uye hunofanira kucheneswa.
A) Kusarudzwa kwemaitiro ekubvisa acidity
H2S neCO2 zviri mugasi rechisikigo zvinonzi gasi rine acid. Kuvapo kwadzo kuchakonzera ngura yesimbi uye kusvibisa nharaunda. Pamusoro pezvo, kana huwandu hweCO2 hwakawandisa, kukosha kwe calorific yegasi rechisikigo kuchaderedzwa. Nokudaro, huwandu hwe acid mugasi rechisikigo hunofanirwa kudzorwa zvakasimba kuti husangane nezvinodiwa zvekugadzirwa uye mhando yechigadzirwa.
Kune nzira yekunyudza solvent, nzira yekunyudza physical, nzira yekuderedza oxidation uye nzira yekubvisa acid gasi kubva mugasi rechisikigo nenzira ye molecular sieve. Parizvino, nzira yekunyudza solvent inozivikanwa zvikuru uye inoshandiswa zvakanyanya. Inzira yekubvisa acid kubva mu solvent yakavakirwa pa reversible chemical reaction uye kushandisa alkaline solvent semushonga unonyudza. Iyo solvent inobatana ne acid components (kunyanya CO2) mu feed gas kuti igadzire makemikari. Gasi re acid rinonyudza mvura yakawanda rinogona kuora nekuburitsa acid gasi kana tembiricha yakwira uye kudzvanywa kwadzikira, kuitira kuti solvent ikwanise kugadziriswa uye kushandiswa.
Panyaya yekushandiswa kwesimba, chiyero chekurapa, mari yekudyara uye mari yekushandisa, nzira yeMDEA amine liquid ndiyo nzira yakakodzera, saka nzira yeMDEA amine liquid inosarudzwa kuti ibvise acid muchirongwa ichi.
B) Kusarudzwa kwemaitiro ekupera mvura mumuviri
Maitiro ekubvisa mvura kubva mugasi rechisikigo anowanzo sanganisira kupera mvura kubva mugasi rechisikigo patembiricha yakaderera, kunyudzwa kwe desiccant yakasimba uye kunyudzwa kwe solvent. Kupatsanurwa kwechando kunonyanya kushandiswa kudzivirira hydrate yegasi rechisikigo kana tembiricha yakaderera, asi tembiricha yakaderera inobvumirwa ishoma, iyo isingakwanise kusangana nezvinodiwa zve liquefaction yegasi rechisikigo; kunyudzwa kwe solvent kunowanzo sanganisira concentrated acid (kazhinji concentrated phosphoric acid nedzimwe organic acids), glycol (inowanzo shandiswa triethylene glycol), nezvimwewo, asi nzira idzi dzine kudzika kwakaderera kwemvura, iyo isingagone kushandiswa mu cryogenic unit; nzira dze desiccant dzakasimba dzemvura dzinosanganisira silica gel method, molecular sieve method kana musanganiswa wenzira mbiri idzi.
Kunyungudika kwegasi rechisikigo uye kushaya mvura mumuviri kunofanirwa kushandisa nzira yakasimba yekunyungudika. Nekuti molecular seeve ine adsorption yakasarudzika, ine hunhu hwakawanda hwekunyungudika pasi pekumanikidzwa kwakaderera kweutsi hwemvura, uye inogona kubvisa zvakare gasi reasidhi rakasara panguva imwe chete, 4A molecular seeve inoshandiswa seadsorbent yekubvisa mvura mumuviri muchirongwa ichi.
C) Kusarudzwa kwenzira yekubvisa mercury
Parizvino, kune mhando mbiri dzekubvisa mercury: nzira yeHGSIV molecular sieve adsorption yekambani yeUOP muUnited States uye maitiro emakemikari pakati pemercury nesarufa nekushandisa sarufa impregnated activated carbon kugadzira mercury sulfide, iyo inonyungudutswa pa activated carbon. Yekutanga inodhura zvakanyanya uye yakakodzera chiitiko chine mercury yakawanda; yekupedzisira inodhura zvishoma uye yakakodzera chiitiko chine mercury shoma.
Kune rumwe rutivi, mari yekushandisa HGSIV molecular sieve yakakwira zvikuru; kune rumwe rutivi, huwandu hwemercury mugasi rekudyisa reyuniti iyi hwakaderera. Saka, kushandiswa kwesulfuri yakanyudzwa mu activated carbon mercury removal process, kambani iyi yakabudirira zvikuru.
Tinoramba tichienderera mberi nepfungwa yedu yebhizinesi rekuti "Hunhu, Kushanda, Kugadzira Zvinhu Zvitsva uye Kuvimbika". Chinangwa chedu ndechekugadzira kukosha kwakanyanya kune vatengi vedu nemidziyo yedu yakapfuma, michina yemazuva ano, vashandi vane ruzivo uye vanopa masevhisi akanaka ekutengesa maCylinders eChina Aluminium Aluminum ari kutengeswa. Chinangwa chebhizinesi redu ndechekupa mhinduro dzemhando yepamusoro, sevhisi yehunyanzvi, uye kutaurirana kwechokwadi. Tinokugamuchirai shamwari dzese kuti muedze kutenga kuti muve nerudo rwebhizinesi diki kwenguva refu.
Mutengo wakaderedzwa mutengo MaSilinda eAluminium eGasi reChina, Masirinda eGasi eIndasitiri, Tichapa zvinhu zviri nani zvikuru nemagadzirirwo akasiyana-siyana uye masevhisi akakodzera. Panguva imwe chete, gamuchirai maodha eOEM, ODM, kokai shamwari dziri kumba nekune dzimwe nyika pamwe chete mubudiriro yakajairika uye muwane hunyanzvi hwese, kuvimbika, uye wedzerai mikana yebhizinesi! Kana muine chero mubvunzo kana muchida rumwe ruzivo yeukai kutibata nesu. Tave tichitarisira kugamuchira mibvunzo yenyu munguva pfupi iri kutevera.
