Natural gas ọdụ gas ọgwụgwọ skid bụ tumadi na-emeso skid ọdụ nke sọlfọ ngwaọrụ mgbake, nakwa dị ka n'efu gas nke mmiri mmiri sọlfọ ọdọ mmiri na TEG n'efu gas nke akpịrị ịkpọ nkụ ngwaọrụ nke sọlfọ ngwaọrụ mgbake.
Nhazi na ikike nhazi nke skid dabara na ngwaọrụ mgbake sọlfọ na ngwaọrụ nkụda mmụọ.
Natural gas ọdụ gas ọgwụgwọ skid nwere ike kewaa anọ edemede

1. Mbelata na ntinye usoro
Ụkpụrụ nke mbelata na usoro absorption bụ na ọdụ gas bụ hydrogenated, sọlfọ-nwere ihe ndị dị na ọdụ ọdụ na-ebelata ka H2S, emepụtara H2S na-ahọrọ na-etinye obi gị dum site amine usoro, na n'ikpeazụ a na-amịpụta ọhụrụ ma ọ bụ gas na-abanye na Claus unit maka ikesa mmeghachi omume. Usoro Hydrogenation nwere nnukwu ego na ụgwọ ọrụ dị elu, mana a na-eji ya na mba na mpaghara nwere oke nchekwa gburugburu ebe obibi chọrọ n'ihi na ọ nwere ike nweta mkpụrụ sọlfọ dị elu, dị ka ihe karịrị 99.8%.

2 Usoro nnabata oxidation
Usoro nnabata oxidation bụ usoro nke mbụ na-ebunye sulfide na gas ọdụ na SO2, wee banye SO2 na ngwọta (ma ọ bụ ihe mgbaze), ma mesịa nwetaghachi ya n'ụdị sulfate, sulfide na SO2.
E nwere ọtụtụ ụzọ nke ụdị a, ọtụtụ n'ime ha na-eji maka flue gas desulfurization ma ọ bụ ọgwụgwọ nke ọdụ gas si smelters na sulfuric acid osisi, na Wellman Lord na-eji usoro Claus ọdụ gas ọgwụgwọ.

3. Usoro Claus dị ala
Nkà na ụzụ Claus dị ala dị ala bụ mmeghachi omume Claus n'okpuru ebe igirigi sọlfọ, ya mere a na-akpọkwa ya usoro mgbake sọlfọ sub ntụpọ. Mmeghachi omume Claus bụ usoro mmeghachi omume exothermic siri ike. Ya mere, obere okpomọkụ na-enyere aka ngbanwe nke nha nha na ntụziaka nke ọgbọ sọlfọ, nke nwere ike imeziwanye mgbake sọlfọ. Dị ka mmekọrịta dị n'etiti Claus mmeghachi omume na unit, ala okpomọkụ Claus usoro nwere ike kewaa n'ime onwe obere okpomọkụ Claus usoro na jikọtara obere okpomọkụ Claus usoro.

4. Usoro mmiri ozuzo kpọmkwem usoro oxidation
Usoro oxidation na-aga n'ihu nke mmiri mmiri bụ ụdị nkà na ụzụ usoro na-eme ka H2S oxidize ozugbo na sọlfọ elemental. Ụkpụrụ nke usoro a bụ ịmịnye H2S na ọdụ gas na ngwọta desulfurization, wee oxidize ya iji mepụta sọlfọ elemental.

Usoro nka

1 SO2 ≤ 400mg/Nm3 (ndabere akọrọ, 3vol% O2)
2 kwa afọ mmepụta oge 8000 awa
3 Mgbanwe na-arụ ọrụ 50% ~ 120%
