Igikoresho cyo koroshya imyuka isanzwe

Intangiriro

Ibikoresho byo kuryoshya imyuka karemano byo mu bwoko bwa molecular sieve (desulfurization), byitwa kandi gukuraho sulfide ya molecular sieve muri gaze karemano, ni igikoresho cy'ingenzi mu gukuraho H2S muri gaze karemano no mu kuvura gaze karemano.

Urugendo rw'ibikorwa

Iyi mashini ikoresha inzira eshatu z'iminara, imwe yo kunyuzamo umunara, imwe yo kuvugurura umunara n'indi yo gukonjesha umunara. Nyuma yo gukuramo amazi ya hydrocarbon yashyizwemo binyuze mu gikoresho cyo gutandukanya icyuma gishyushya, umwuka w'ibiryo winjira mu munara wo gusukura icyuma gishyushya. Amazi na mercaptan biri mu mwuka w'ibiryo byinjizwa mu icyuma gishyushya kugira ngo amazi agere ku mazi n'inzira yo kunyuzamo mercaptan. Gazi isukuye iva mu mazi abira no gukuraho mercaptan yinjira mu ruganda rw'ibiryo kugira ngo ikuremo umukungugu w'icyuma gishyushya, hanyuma yoherezwa mu mahanga nk'umwuka w'ibiryo.

Uduce twa molekile tugomba kuvugururwa nyuma yo guhumeka amazi na mercaptan runaka. Nyuma yo kuyungurura umukungugu wa gaze y’ibicuruzwa, igice cya gaze y’ibicuruzwa gikurwamo nk’umwuka wo kuvugurura. Iyo gaze imaze gushyushywa kugeza kuri 300 ℃ n’itanura rishyushya, umunara ushyushya buhoro buhoro kugeza kuri 272 ℃ binyuze mu munara wa molekile wo gusukura sulfurization warangije inzira yo guhumeka kuva hasi kugera hejuru, kugira ngo amazi na mercaptan byinjijwe ku ruhu rwa molekile bishobore gutandukanywa kandi bibe gaze yo kuvugurura itunganywa kugira ngo birangize inzira yo kuvugurura ivugurura.

Nyuma y'umunara wo kuvugurura, umwuka ukurura cyane winjira muri kondensateri y'umwuka ukurura neza hanyuma ukonje kugeza kuri 50°C, ku buryo amazi menshi akonjeshwa, hanyuma agatandukana n'icyuma gitandukanya, maze umwuka ukurura neza cyane ugatwikwa.

Umunara w’urusyo rwa molekile ugomba gukonjeshwa nyuma yo kongera kuvugururwa. Kugira ngo wongere ugarure neza kandi ukoreshe ingufu z’ubushyuhe, umwuka wo kongera kuvugururwa ubanza gukoreshwa nk’umwuka ukonje uhuha, maze umunara ukonjeshwa kugeza kuri 50°C uhereye hejuru ugana hasi unyuze mu munara w’urusyo rwa molekile uhuha warangije igikorwa cyo kongera kuvugururwa. Muri icyo gihe, ushyushya ubwawo. Umwuka ukonje uhuha woherezwa mu munara ukonje hanyuma ugashyirwa mu itanura rishyushya gaze kugira ngo ushyushye. Nyuma yo gushyushya, umunara w’urusyo rwa molekile uhuha uhuha uhuha nk’umwuka wo kongera kuvugururwa. Igikoresho gihindura buri masaha 8.
