Uburyo bwo kugarura hydrocarbons zoroheje zivuye muri gaze ifitanye isano mu mirima ya peteroli (1)
Itsinda kugarura hydrocarbons zoroheje kuva kuri gaze ifitanye isano n’ibikomoka kuri peteroli ni inzira y’ingenzi mu nganda za peteroli na gaze. Gaze ifitanye isano n’ibikomoka kuri peteroli, ikunze kuboneka hamwe na peteroli, irimo ibintu by’agaciro nka gaze karemano (NGL) na gaze ya peteroli ivanze n’amazi (LPG). Kugarura izi hydrocarbons zoroheje ntabwo bitanga agaciro k’umuyoboro wa gaze gusa ahubwo binafasha mu kugabanya imyuka ihumanya ikirere. Muri iyi nkuru, turasuzuma akamaro ko kugarura gaze ifitanye isano na NGL na LPG hamwe n’ikoranabuhanga riri muri iyi nzira.
Gukura kwa NGL muri gaze ifitanye isano bikubiyemo gutandukanya no gukuramo ibinyabutabire bya gaze karemano nka ethane, propane, na butane. Ibi bice bifite agaciro gakomeye mu bucuruzi kandi bikoreshwa nk'ibiribwa by'inganda zikora peteroli, ndetse no mu gukora plastiki, kawurute y'ubukorikori, n'ibindi bicuruzwa by'inganda. NGL ikomoka kuri gaze ifitanye isano ni ingenzi mu kongera ubushobozi bw'ubukungu bw'umuyoboro wa gaze no kugabanya gusesagura umutungo w'agaciro.
Ibisobanuro bigufi by'iyi gahunda ni ibi bikurikira:
1) Sisitemu yo kuvanga no kongera ingufu za gaze karemano
1) Ibisobanuro by'inzira
Imyuka ishyirwamo umuvuduko ugera kuri 0.3 MPaG hanyuma ikavangwa n'umuvuduko muke hanyuma ikavangwa na 3.9 MPaG. Hanyuma umuvuduko uvanze uvangwa n'umuvuduko muke hanyuma ukinjira mu gikoresho cyo hepfo.
2) Ibipimo by'igishushanyo
Ubushobozi bwo gutunganya gazi:
Umuvuduko Ukabije: 12500 Nm3/h;
Umuvuduko muke: 16166.7 Nm3/h;
2) Sisitemu yo kugabanya amazi mu mwuka usanzwe
1) Ibisobanuro by'inzira
Kuba hari ubushuhe muri gaze karemano bikunze gutera ingaruka zikomeye: ubushuhe na gaze karemano bishobora gukora ubushyuhe cyangwa urubura kugira ngo bizibe imiyoboro y'amazi mu bihe bimwe na bimwe.
Gukuraho amazi mu mwuka karemano bikoresha uburyo bwo kuyungurura amazi mu buryo bwa molekile. Kubera ko urushundura rufite ubushobozi bwo guhitamo uburyo bwo kuyungurura amazi mu buryo bukomeye kandi rufite ubushobozi bwo kuyungurura amazi mu gihe cy'umwuka muke w'amazi, iki gikoresho gikoresha urushundura rwa molekile rwa 4A nk'urushundura rwo kuyungurura amazi mu buryo bwa molekile.
Iki gice gikoresha inzira y’iminara ibiri kugira ngo gikurure ubushuhe, gikoresha uburyo bwa TSA kugira ngo gisesengure ubushuhe bwinjijwe mu ruziga rwa molekile, kandi gikoresha uburyo bwo guhumeka kugira ngo gikure ubushuhe buvanywe mu ruziga ruvanze n’ubushuhe.
2) Ibipimo by'igishushanyo
Ubushobozi bwo gutunganya gazi ku biryo 70 × 104 Nm3/d
Umuvuduko w'amazi 3.5MPaG
Ubushyuhe bwo kwinjiza amazi 35 ℃
Umuvuduko wo kuvugurura 3.5MPaG
Ubushyuhe bwo kongera kuvugurura ~ 260 ℃
Amavuta ashyushye akomoka ku bushyuhe busubira
Ibikubiye muri H2O mu mwuka usukuye ＜ 5 ppm
