Ibisobanuro bya buri sisitemu

Kugaburira gazi yo kuyungurura no kugabanya ingufu

1） Ibisobanuro

Kugaburira gazi karemano iva mumigezi itembera mu muyoboro ku muvuduko wa 5.0 ~ 6.0MpaG yinjira mu byokurya bya gaz inlet filter itandukanya nyuma yumuvuduko ukabije, kandi ikinjira muri sisitemu yo hasi nyuma yo gutandukana no gupima.

Ibikoresho nyamukuru bitunganyirizwa ni kugaburira gazi ya filteri itandukanya, fluxmeter, kugenzura igitutu, nibindi.

2） Gushushanya ibipimo

Ubushobozi bwo gutunganya: 20 × 10⁴Nm³/ umunsi

Urwego rwo guhindura: 50% ~ 110%

Sisitemu yo kubanziriza

Kugaburira ishami rya deacidification

1） Ibisobanuro

Gazi yo kugaburira ivuye hejuru yinjira mumashanyarazi ya deacidification, ikoresha igisubizo cya MDEA mugukuraho imyuka ya aside nka CO₂na H.₂S muri gaze yo kugaburira.

Gazi isanzwe yinjira mu gice cyo hepfo yikurura （ikurura umunara） ikanyura mu cyuma kiva hasi kikajya hejuru; Igisubizo cya MDEA cyuzuye (igisubizo cyoroshye) cyinjira kiva mugice cyo hejuru cyikurura kandi kinyura mumashanyarazi kuva hejuru kugeza hasi. Igisubizo cyinyuma MDEA igisubizo hamwe na gaze gasanzwe ihura neza mumashanyarazi, CO₂muri gaze irashiramo kandi ikinjira mucyiciro cyamazi, kandi ibice bitabujijwe gusohoka biva hejuru yikuramo hanyuma bikinjira muri gaz ya decarbonisation ikonjesha. Gazi ivuye muri gaze ya gaze ya decarbonisation yinjira murwego rwo gukuraho gaze ya gazi ya mercure, hanyuma kondensate ikajya mumashanyarazi.

Ibiri muri CO₂muri gaze karemano yatunganijwe iri munsi ya 50ppmv.

Igisubizo cya MDEA gikurura CO₂yitwa igisubizo gikungahaye, cyoherejwe kuri flash umunara, na gaze karemano yakawe na depression ikoherezwa muri sisitemu ya lisansi. Nyuma yo guhanahana ubushyuhe hagati ya flash ikungahaye cyane hamwe nigisubizo (fluid lean) gisohoka kiva munsi yumunara wububyutse, uzamure ubushyuhe bugere kuri ~ 98 ℃ kugeza hejuru yumunara wivugurura, hanyuma ukore ibyamburwa bishya muminara mishya kugeza igihe urwego rwamazi rwamazi ruteye rugera kumurongo.

Amazi yinini ava muminara yubuzima bushya anyura mumashanyarazi akungahaye kandi akennye kandi akonjesha. Amazi yinanutse akonjeshwa kugeza ~ 40 ℃, akandamijwe na pompe yamazi yoroheje kandi yinjira kuva mugice cyo hejuru cyumunara.

Gazi isohoka hejuru yumunara wububyutse yinjira muri gaze ya acide ikoresheje icyuma gikonjesha aside, gaze ivuye muri gaze ya acide yoherejwe muri sisitemu yo gusohora gaze, hanyuma kondensate ikoherezwa mumashanyarazi nyuma yo kotswa igitutu na pompe yo kugarura.

Inkomoko yubushyuhe bwa reboiler yumunara mushya ushyutswe namavuta yohereza ubushyuhe. Ibikoresho byingenzi byo gutunganya iki gice ni umunara winjiza n'umunara wo kuvugurura.
