Ubushinwa Bwiza Bwinshi Ubunini bwa LNG bwohereza ibicuruzwa hanze - 67 ~ 134 TPD skid yashizwe mumashanyarazi ya gaze gasanzwe - Rongteng

Incamake ya sisitemu

Kugaburira gaze gasanzwe yinjira muri sisitemu yo guteganya gaze nyuma yo kuyungurura, gutandukana, kugenzura umuvuduko no gupima. Nyuma ya CO₂, Hg na H.₂O ikuweho, yinjira mu isanduku ikonje ya liquefaction, ikonjeshwa, ikungururwa na azote ikurwa muri plaque fin ubushyuhe, hanyuma igasubira mu isanduku ikonje kugirango ikomeze gukonja, gukonjesha, gutereta no kumurika kuri flash tank. Icyiciro cyamazi gitandukanijwe cyinjira mububiko bwa LNG nkibicuruzwa bya LNG.

Inzira nyamukuru nuburyo bwa tekinike yikigo ni:

Koresha MDEA kugirango ukureho karubone;

Icyuma cya molekulari gikoreshwa mugukuraho amazi yumurongo;

Kurandura mercure na sulfure yatewe na karubone ikora;

Koresha muyunguruzi neza kugirango ushungure molekile ya elegitoronike kandi ivumbi rya karubone

Gukuraho azote ukoresheje ubushyuhe buke;

Inzira yo gukonjesha ya MRC (ivanze na firigo) ikoreshwa kugirango isukure gaze gasanzwe isukuye

Sisitemu y'ibikorwa ikubiyemo:

Gupima no gutandukanya gaze mbisi;

Sisitemu yo kubanziriza (harimo decarburisation, gukuraho mercure, umwuma no gukuramo ivumbi);

Sisitemu yo kugereranya MR na sisitemu yo gukwirakwiza MR;

Sisitemu ya LNG;

Sisitemu yo kubika no gupakira.

Sisitemu yo kugarura bog

Kugaburira gazi yo kuyungurura no kugabanya ingufu

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.
