Kuchotsa Mafuta a Gasi Wachilengedwe: Kuyeretsa Mafuta a Mlatho

Mpweya wachilengedwe, womwe ndi "mafuta ofunikira kwambiri," nthawi zambiri umakhala ndi hydrogen sulfide (H₂S) ndi mankhwala a organic sulfure (mercaptans, COS), omwe ndi oopsa, owononga, ndipo amapanga SOx yoopsa ikayaka. Chifukwa chake, kutsekemera (kutsekemera) ndikofunikira.

Mfundo yaikulu:Mfundo yaikulu ikuphatikizapo kulekanitsa mankhwala a sulfure ndi mpweya wochuluka wa methane pogwiritsa ntchito mankhwala kapena zochitika zakuthupi. Izi zimayang'ana milingo ya H₂S mpaka kufika pa specifications za mapaipi (nthawi zambiri ≤ 4 ppmv) ndi sulfure yonse kuti ikwaniritse miyezo ya chilengedwe/yokonza.

Njira Zofunika:

1. Kumwa kwa Amine (Zosungunulira Mankhwala):Njira yodziwika kwambiri. Alkanolamines (monga, MDEA) amachita zinthu mobwerera m'mbuyo ndi H₂S ndi CO₂ mu absorber. Amine wolemera amapangidwanso mu stripper (pogwiritsa ntchito kutentha), kutulutsa mpweya wa asidi wambiri kuti ugwiritsidwenso ntchito (monga Claus unit) ndikubwezeretsanso amine woonda.
2. Kumwa kwa Zosungunulira Zakuthupi (monga Selexol, Rectisol):Gwiritsani ntchito zosungunulira (monga ma glycols) zomwe zimasungunula sulfure m'thupi pamene pali kupanikizika kwakukulu. Kusinthika kumachitika makamaka mwa kuchepetsa kupanikizika (kubwezeretsa kuwala kwa dzuwa), zomwe zimapereka mphamvu zabwino pakudya kwa sulfure yokhala ndi kupanikizika kwakukulu.
3. Kuthira madzi kolimba (monga, Maselo Ozungulira, Zinc oxide):Amagwiritsidwa ntchito popukuta mozama mpaka kufika pamlingo wotsika kwambiri wa ppm/ppb kapena kuchotsa zinthu zambiri nthawi zina. Ma adsorbents amasunga mankhwala a sulfure pamwamba pake; kukonzanso kumafuna kutentha kapena kusinthidwa.
4. Ndondomeko ya Claus:Sikuti kutsekemera mwachindunji, koma ndikofunikira kwambiri pochiza mpweya wa asidizopangidwandi mayunitsi a amine. Amasintha H₂S kukhala sulfure yoyambira kudzera mu kuyaka pang'ono ndi kuchitapo kanthu (2H₂S + O₂ → S₂ + 2H₂O).

Ubwino:

• Chitetezo:Amachotsa zoopsa za poizoni wa H₂S.
• Chitetezo cha Katundu:Zimaletsa dzimbiri m'mapaipi, ma valve, ndi zida zokonzera.
• Kutsatira Malamulo Okhudza Zachilengedwe:Zimathandiza kuyaka bwino, kuchepetsa kutulutsa kwa SOx ndi mvula ya asidi.
• Ubwino wa Zamalonda:Zimakwaniritsa zofunikira za mapaipi ndi LNG; zimaletsa poizoni wa catalyst kwa ogwiritsa ntchito omwe ali pansi pa mtsinje.
• Kubwezeretsa Sulfure:Amapanga sulfure wofunika kwambiri.

Ziyembekezo za M'tsogolo:Chifukwa cha malamulo okhwima okhudza chilengedwe komanso kukula kwa LNG, kufunika kwa desulfurization yogwira ntchito bwino kumawonjezeka. Zolinga zamtsogolo zikuphatikizapo:

• Zosungunulira Zapamwamba:Zosungunulira zosakanikirana zomwe zimaphatikiza zinthu za mankhwala ndi zakuthupi kuti zisankhe bwino komanso kuti zichepetse kugwiritsa ntchito mphamvu.
• Ukadaulo wa Nembanemba:Kulonjeza kulekanitsa magetsi modular komanso kogwiritsa ntchito mphamvu zochepa, makamaka pochotsa magetsi ambiri kapena mitsinje inayake.
• Kukulitsa Njira:Kukonza bwino mgwirizano pakati pa mayunitsi obwezeretsa, kubwezeretsa, ndi sulfure.
• Njira Zaukadaulo Wachilengedwe:Kufufuza za kuchotsedwa kwa sulfur m'thupi kuti zigwiritsidwe ntchito pa niche.

Kuchotsa mpweya wachilengedwe m'nthaka kudakali ukadaulo wofunikira, kuonetsetsa kuti mphamvu yofunikayi ikugwiritsidwa ntchito bwino, mosawononga chilengedwe, komanso moyenera, komanso kupanga zinthu zatsopano zomwe zimasintha tsogolo lake.
