Babban Ingantacciyar Gas ɗin Gas ɗin Sinawa Masu Kayayyakin Gishiri - Rongteng

Gabatarwa

MDEA halitta iskar gas desulphurization (desulfurization) skid, kuma ake kira MDEA sweeting skid da na halitta gas desulfurization naúrar, shi ne wani key na'urar a cikin halitta gas tsarkakewa ko na halitta kwandishan.

MDEA na'ura mai lalata iskar gas koyaushe ana karɓa lokacin da carbon sulfur na iskar gas ya yi girma, kuma lokacin zaɓin cire H₂Ana buƙatar S don samun iskar acid wanda ya dace da sarrafa shukar Claus, da sauran yanayi waɗanda za a iya zaɓa don cire H₂S; Lokacin cire H₂S da kuma cire babban adadin CO₂, Ana iya amfani da MDEA azaman hanyar amine mai gauraye;

A halin yanzu, babban desulfurization fasahar amfani da masana'antu samar a gida da kuma kasashen waje ne: bushe (jiki) desulfurization, nazarin halittu desulfurization da rigar desulfurization.

Rigar desulfurization ya haɗa da hanyar sha da hanyar iskar shaka ruwa. Hanyar shan sinadarai, wanda aka wakilta ta hanyar sha amine, an yi amfani da shi sosai a masana'antu. Ana canza hydrogen sulfide a cikin iskar gas zuwa lokacin ruwa don tsarkake gas.

Fasaha na desulfurization

Fasahar desulfurization na halitta, a cikin yanayin micro oxygen, na iya canza hydrogen sulfide zuwa sulfur na asali, amma fasahar lalatawar halitta ba ta girma a halin yanzu.

Dry desulfurization fasaha hada da baƙin ƙarfe oxide Hanyar, kunna carbon Hanyar, kwayoyin sieve Hanyar, ion musayar hanya, membrane rabuwa Hanyar, biochemical Hanyar, da dai sauransu a halin yanzu, bushe PSA fasaha ne mafi yadu amfani da kananan-sikelin halitta gas desulfurization jiyya a masana'antu, wanda yake shi ne cikakken kwamfuta-sarrafawa, atomatik aiki, da atomatik kau da laifi hasumiya, don haka kamar yadda aiki da aminci dogon lokaci.

desulfurization hanyoyin

Amorphous iron hydroxide (tsari bushe). Features: yana da halaye na high desulfurization daidaici, high sulfur iya aiki, mai kyau ƙarfi da rashin kula. An yi amfani da shi sosai wajen kawar da hydrogen sulfide a cikin iskar gas, gas ɗin roba, gas na biogas, iskar gas, methane mai coalbed da nau'o'in sulfur na sinadarai daban-daban; A amorphous hydroxyl hadawan abu da iskar shaka desulfurization ne dauki desulfurization, wanda ba zai iya sarrafa desulfurization zurfin. Yana da kyau desulfurization tsari. Tare da jikewa na desulfurizer da shigar da hasumiya na desulfurization, da desulfurization sakamako zai ragu sosai, da kuma abun ciki na hydrogen sulfide a tsarkake halitta gas zai tashi da sauri, don haka ya zama dole don maye gurbin desulfurizer a cikin lokaci.
