100MMSCFD gasi rechisikigo desulphurization skid ine MDEA mhinduro maitiro
Sichuan Hengzhong Clean Energy Equipment Co., Ltd., yakazvarwa muna 2012 uye tinogona kupa mhinduro nemidziyo yekushandisa package yemidziyo yekurapa wellhead. michina yekutonhodza gasi rechisikigo, pasuru yekudzoreredza sarufa, Kubvisa LPG uye NGL recovery unit, Chirimwa chemvura inonyungudutsa LNG, chikamu chekugadzira hydrogen, paki yekuburitsa helium, seti dzejenareta yegesi.
Chidzitiro chekubvisa sulphurization chakazara chinosanganisira masisitimu matatu: sisitimu yekugadzira, sisitimu yekudzora zvishandiso uye sisitimu yemagetsi. Zvichienderana nemhepo dzakasiyana, inogona kuchinjwa.
Zvichienderana nemamiriro chaiwo egasi, tinoshandisa nzira yakanakisisa uye hurongwa husingadhuri zvakanyanya kuti tisangane nezvinodiwa nevatengi. Midziyo inosungirirwa paskid inoita kuti kutakurwa nekuiswa zvive nyore.
- Maitiro makuru ekushandisa mhinduro yeMDEA kubvisa CO2 neH2S:
Chisikwa chinobva kumusoro chinopinda muchikamu chekubvisa acid, icho chinoshandisa mhinduro yeMDEA kubvisa magasi ane acid akadai seCO2\H2S kubva mugasi risina kubikwa.
Gasi rechisikigo rinopinda mu absorber richibva pasi royerera richikwira. Mhinduro yeMDEA yakadzorerwa zvizere (mhinduro isina kusimba) inopinda mu absorber richibva kumusoro royerera richidzika. Ma countercurrents emhinduro yeMDEA negasi rechisikigo anobata absorber zvizere, achitora CO2 neH2S mugasi uye achizviendesa ku liquid phase. Zvikamu zvisina kunyudzwa zvinotorwa kubva pamusoro pe absorber zvopinda mu deacidification gas cooler uye separator. Gasi rinobuda mu deacidification gas separator rinopinda mu feed gas pre-cooling unit, uye condensate inotumirwa ku flash tank.
Thuwandu hweCO2 mugasi rechisikigo rakagadziriswa huri pasi pe50 PPM, uye huwandu hweH2S huri pasi pe4 PPM.
Mhinduro yeMDEA inonwisa CO2 neH2S, inonzi mvura yakapfuma, inotumirwa kuflash tower, uko kumanikidzwa kunoderedzwa uye gasi rechisikigo rinobuda rinotumirwa kusystem yekuburitsa mweya. Mvura yakapfuma inozochinjana kupisa nemhinduro (mvura yakakora) inoyerera kubva pasi petower yekudzoreredza. Tembiricha inozokwidzwa kusvika ~203 °F yotumirwa kuchikamu chepamusoro chetower yekudzoreredza, uko inobviswa nekudzoreredzwa kusvika mvura yakakora yasvika pahuwandu hwayo.
Mvura isina kusimba inobva mushongwe yekudzoreredza inopfuura nemuchinochinja-chinja kupisa kwemvura ine mvura yakawanda uye muchinotonhodza mvura isina kusimba, inotonhodzwa kusvika 113 °F, uye inomanikidzwa nepombi yemvura isina kusimba isati yapinda muchikamu chepamusoro cheshongwe yekunyudza.
Gasi rinobuda kubva pamusoro peshongwe yekuvandudza rinodarika nemuchitonhodza chegasi rine acid uye rinopinda muchitokisi chegasi rine acid. Gasi rinobuda muchitokisi chegasi rine acid rinotumirwa kusystem yekuburitsa gasi rine acid, uye condensate inodzokera kutangi reMDEA buffer.
Nzvimbo inodziya ye reboiler ye regeneration tower inodziiswa nemafuta anodziya.
Midziyo mikuru yemuchina uyu ishongwe yekunyudza uye shongwe yekudzoreredza.
Magadzirirwo ezviyero：
Kugona kugadzira: 100MMSCFD
Dhizaini yehuwandu hweCO2 mugasi risina kubikwa: 5% (mol%)
H2S yakawanda mugasi risina kubikwa ndeye 8ppmv
Kumanikidzwa kwekushanda kweshongwe yekunyorova: 986.1psig
Tembiricha yekushanda kweshongwe yekunyorova: 104 ℉ ~ 140 ℉
Kumanikidzwa kwekushanda kweshongwe yekuvandudza: 4.351psig ~ 7.252psig
Tembiricha yekushanda kweshongwe yekuvandudza: 203 ℉ ~257 ℉
Kupisa kunodzoreredza: Kupisa mafuta anodziya
CO2 yakawanda mugasi risina acid ≤50PPM
huwandu hwegasi mugasi risina acid ≤4PPM
3) Mashandisirwo ekushandisa
50% ~ 110%
- Sisitimu yekudzora midziyo
Kuti tinyatso tarisa maitiro ekugadzira michina yese, uye kuve nechokwadi chekuti mashandiro akavimbika uye mashandiro ari nyore uye kugadzirisa, sisitimu yekudzora michina inonyanya kusanganisira:
Sisitimu yekudzora yakaparadzirwa (DCS)
Sisitimu yeZvishandiso Zvekuchengetedza (SIS)
Sisitimu yeAlarm yeMoto neGasi (FGS)
Terevhizheni yeClosed-circuit (CCTV)
Sisitimu yekuongorora
- Sisitimu yekushandisa
Sisitimu iyi inonyanya kusanganisira: mudziyo wemhepo, nitrogen unit, heat transfer oil unit, desalted water unit uye cooling circulating water unit.
