Kubvisa kabhoni mugasi rechisikigo (kubvisa kabhoni mugasi rechisikigo) skid, chinhu chakakosha mukuchenesa kana kurapa gasi rechisikigo.
Hunhu hwekabhoni dhayokisaidhi mugasi rechisikigo hahufanirwe kupfuura 3%. Uye kabhoni dhayokisaidhi mumvura mushure mesimbi ine ngura yakasimba. Kana pH yakafanana, chiyero cheacidity chekabhoni dhayokisaidhi chakakwirawo, saka mwero wekuora kwekabhoni dhayokisaidhi pasimbi wakakwirawo.
Saka, kuti pave nekushandiswa kwekubvisa kabhoni mugasi rechisikigo, zvakakosha kuti pave nekupisa kwakasimba panguva yekubvisa kabhoni, saka gasi rechisikigo mushure mekunyoroveswa kwekupisa harina kukodzera kubviswa kabhoni mugasi rechisikigo. Zvisinei, kana tikasafunga nezvezvigadzirwa zvekubvisa kabhoni mugasi rechisikigo, asi tikatora nzira yekuparadzanisa tembiricha yakaderera, zvichatungamira zvakananga kukushanda kwekubvisa kabhoni mugasi rechisikigo. Parizvino, kushandiswa kwekubvisa kabhoni mugasi rechisikigo kunogona chete kugadzira nzira yeammonia yedoro.
Chati yekuyerera
Zvichienderana nehunhu hwetekinoroji yeMDEA, nzira yekudzoreredza chikamu inodiwa kuti gasi rechisikigo ribviswe mucarbonization. Pakati pazvo, gasi rechisikigo rinonyanya kupinda mu absorber kubva pasi, uye rinosangana nemhinduro yeMDEA kubva kumusoro kusvika pasi mu absorber, asi mhinduro zhinji yecarbon dioxide mugasi rechisikigo inobviswa kabhoni. Gasi rechisikigo rakanyorova rakacheneswa rinonyanya kuparadzaniswa neshongwe yekunyudza uye rinotonhodzwa, uye rozobviswa mvura. MDEA kubva pasi peshongwe yekunyudza inoda simba kuti ipinde mukurapa kwekushaya mvura, uye chikamu chepamusoro cheshongwe yekunyudza chinopinda mushongwe. Mushure mekubviswa mucompression, kabhoni dioxide inonyudzwa inogadziriswa uye inopiswa nemhepo pakati peshongwe yekunyudza. Nenzira iyi chete ndiyo inogona kuchengetedzwa tembiricha yemhinduro. Mushure mekunge mhinduro yeMDEA kubva pasi peshongwe yatonhodzwa, mhinduro inopinda pamusoro pekunyudzwa, kuitira kuti ipedzise maitiro ese ekutenderera kwemhinduro. Pamusoro pezvo, kuitira kuve nechokwadi chekuti mhinduro inogona kudzokororwa uye kucheneswa zvakare, 15% yemhinduro inodiwa kuti ibviswe mhinduro. Kuti kuchengetedza maitiro ekubvisa kabhoni mugasi rechisikigo, sisitimu ichagadziriswazve kuburikidza nemhinduro.
Zvinhu zvinoshanda
Kushanda kwe decarbonization nenzira yeMDEA ndeye 99%.
Kuti ibvise kabhoni dhayiokisijeni (CO2) kubva mugasi rekudya, mvura ine amine yedoro inosanganiswa neCO2 mugasi rekudya. Kurasikirwa negasi kwakaderera uye kushandiswa kwesimba rakawanda. Nzira ye alcohol amine inogonawo kushandiswa kubvisa H2S kubva mugasi rekudya.
