Yakakwira Hunhu China Gasi Dehydration Unit Vagadziri - MDEA nzira decarburization skid yeyakasikwa gasi conditioning michina - Rongteng

Tsanangudzo

Natural gasi decarburization (decarbonization) skid, chinhu chakakosha mukuchenesa gasi kana kurapwa.

Izvo zvirimo zvekabhoni dhaidhi mugasi rechisikigo mhando chiyero hachifanirwe kupfuura 3%. Uye carbon dioxide mumvura mushure mokunge simbi yave nekuora kwakasimba zvikuru. Kana iyo pH yakakosha yakafanana, iyo acidity reshiyo yekabhoni dhaikisaidhi yakakwirawo, saka dhigirii yekuora yecarbon dioxide pasimbi zvakare yakakwirira.

Naizvozvo, nekuda kwekudiwa kwegasi decarburization, zvinodikanwa kuve nekupisa kwakasimba kwekuita mukati mekuita decarburization, saka gasi rechisikigo mushure mekunyorovesa kupisa kurapwa harina kukodzera gasi decarburization. Nekudaro, kana isu tisingatarise zvigadzirwa zvegasi decarbonization, asi tora nzira yekudzika kwakadzika tembiricha kuparadzaniswa, inotungamira zvakananga kukubudirira kwegasi decarbonization. Parizvino, kushandiswa kwegasi decarbonization kurapwa kunogona kungoita doro ammonia nzira.

Kuyerera chati

Zvinoenderana nehunhu hweMDEA tekinoroji, chikamu chekuvandudza chikamu chinodiwa kune yakasikwa gasi decarbonization. Pakati pavo, gasi rechisikigo rinonyanya kupinda mumudziyo kubva pasi, uye rinosangana neMDEA mhinduro kubva kumusoro kusvika pasi mumudziyo, asi yakawanda ye carbon dioxide solution mugasi rechisikigo yakasvibiswa. Iyo yakanyorova yakanatswa gasi rechisikigo rinonyanya kuparadzaniswa neshongwe yekunyura uye yakatonhodzwa, uye yobva yapera mvura. Iyo MDEA kubva pasi peiyo shongwe yekunyura inoda simba rekupinda mukurapa kwekushaya mvura, uye chikamu chepamusoro cheshongwe yekunyura inopinda mushongwe. Mushure mekuora, iyo yakanyungudutswa kabhoni dhaikisaidhi inogadziriswa uye inopisa nemhepo pakati peiyo shongwe yekuvandudza. Nenzira iyi chete inogona kuchengetedzwa tembiricha yemhinduro. Mushure mokunge mhinduro yeMDEA kubva pasi peshongwe yakanyoroveswa, mhinduro inopinda pamusoro pekutora, kuitira kuti ipedze kutenderera kwese kwekugadzirisa. Mukuwedzera, kuitira kuti unyatsoona kuti mhinduro yacho inogona kushandiswa zvakare uye kucheneswa zvakare, 15% yemhinduro inodiwa pakubvisa mhinduro. Kuti uchengetedze iyo decarbonization process yegasi rechisikigo, iyo sisitimu ichagadziridzwa kuburikidza nemhinduro.

Zvishandiso zvinoshanda

Kushanda kwe decarbonization neMDEA nzira ndeye 99%.
Kuti ubvise carbon dioxide (CO2) kubva kufeed gas, aqueous solution nedoro amine as solvent inopindirana ne CO2 mufeed gas. Kurasikirwa kwegasi kwakaderera uye kushandiswa kwakanyanya kwesimba. Iyo doro amine nzira inogonawo kushandiswa kubvisa H2S kubva kugasi rekudya.
