Ubuziranenge Bwiza Ubushinwa LNG Abatanga uruganda rwa gazi - Yabigenewe 50 × 104m3 / D uruganda rwamazi ya gazi - Rongteng

Intangiriro

Kubaka umushinga 50 × 10⁴m³/ D umushinga wa gazi isanzwe hamwe nibikoresho bifasha hamwe na 10000 m3 LNG yuzuye. Ibice nyamukuru bitunganyirizwamo ibiryo byokugaburira gazi, ishami rya decarbonisation, ishami rya dehidrasi, mercure hamwe nogukuraho hydrocarubone iremereye, ishami ryamazi, ububiko bwa firigo, igitutu cya flash, igitutu cya LNG nibikoresho byo gupakira.

Nigute uburyo bwo kuvura gaze mbere yo gutemba bukora?

Iriba ryibiryo byibimera biza muburyo bwa gaze na pipe. Gazi isanzwe ikurwa mubutaka irimo umwanda, amazi nandi mazi ajyanye nayo, kuburyo mbere yuko amazi ashobora kubaho, gaze igomba kunyura muburyo bwo kuvura kugirango ikureho ibintu bitifuzwa. Gazi inyura murukurikirane rwamato, compressor hamwe nu miyoboro aho gaze itandukanijwe buhoro buhoro n'amazi aremereye hamwe n’umwanda.

Ubwa mbere, amazi na kondensate bivanwaho, bigakurikirwagukuraho gaze ya aside(Dioxyde de carbone, CO2), hydrogen sulfide (H2S) na mercure (Hg). Ibi bintu ntibikenewe, kuko bishobora gutera urubura mugihe cyo kuyungurura no kwangirika mumiyoboro hamwe no guhanahana ubushyuhe bwa LNG. Ibivangavanze bisigaye byateguwe mbere, nibindi, biremereye, amazi ya gaze karemano noneho bitandukanijwe nuruvange mbere yuko amazi abaho. Hydrocarbone yakuweho irashobora kubikwa no kugurishwa ukwayo. Gazi isigaye ahanini igizwe na metani na Ethane zimwe na zimwe, zizanwa mumazi.

Nigute amazi ya LNG akora?

Gutwara gaze isunitswe intera ndende ukoresheje umuyoboro birashobora kubahenze kandi bigatwara igihe, ariko mugukonjesha gaze karemano kugeza kuri -162 ° C, ihinduka ibintu byamazi, kandi ingano yayo igabanuka inshuro 600. Ibi bituma bishoboka gutwara gaze mubwato, kandi iyi nzira irashoboka muruganda rwa LNG. Uburyo bwo gukonjesha no gukonjesha LNG bishingiye ku kuzenguruka kwa firigo ya termodinamike, kandi bibera mu guhanahana ubushyuhe bwa kirogenike, bikurura ubushyuhe buturuka kuri gaze gasanzwe. Gazi ya Flash na BOG birashobora gukoreshwa nkibicanwa bya turbine zikoreshwa mumashanyarazi.

Dutandukanya cyane cyane muburyo bubiri bwingenzi bwo gutembagaza: inzira ya kasike ya classique ya classique aho hakoreshwa firigo zitandukanye ziva mubushyuhe butandukanye, hamwe na cycle ya firigo ivanze aho ikomeza, imwe ivanze ya firigo. Ibyo ari byo byose, ibicuruzwa byanyuma ni LNG, ibikwa mu bigega bya kirogenike ku rubuga mbere yo koherezwa.
