Etan gaz\u0131n\u0131n tesad\u00fcfi ke\u015ffi<\/h2>

Etan, ilk kez 1834 y\u0131l\u0131nda \u0130ngiliz kimyager Michael Faraday taraf\u0131ndan ke\u015ffedildi. Faraday, \u00e7e\u015fitli hidrokarbon gazlar\u0131n\u0131 incelerken bu gaz\u0131 yeni bir bile\u015fik olarak tan\u0131mlad\u0131. Faraday, gazlar\u0131 s\u0131v\u0131 h\u00e2lde test etmeye ve \u00f6zelliklerini incelemeye \u00e7al\u0131\u015f\u0131yordu. Baz\u0131 organik maddelerin ayr\u0131\u015fmas\u0131ndan elde edilen basit hidrokarbon bile\u015fiklerinden birinin farkl\u0131 kimyasal \u00f6zellikler g\u00f6sterdi\u011fini fark etti. Daha fazla incelemenin ard\u0131ndan bu gaz\u0131 yeni bir doymu\u015f hidrokarbon olarak tan\u0131mlad\u0131. Daha sonra, 19. y\u00fczy\u0131l\u0131n sonlar\u0131nda di\u011fer bilim insanlar\u0131 taraf\u0131ndan etan gaz\u0131n\u0131n kimyasal form\u00fcl\u00fc ke\u015ffedildi.<\/p>

Etan, alkanlar ailesinin ikinci \u00fcyesi<\/h2>

Etan ad\u0131 Yunanca\u2019da \u201cparlamak veya yanmak\u201d anlam\u0131na gelir, \u00e7\u00fcnk\u00fc etan gaz\u0131 kolayca yanar ve parlak bir alev olu\u015fturur. Etan, alkanlar ailesinin ikinci \u00fcyesi olarak C\u2082H\u2086 form\u00fcl\u00fcne sahip doymu\u015f bir gaz hidrokarbondur ve metandan sonra do\u011fal gaz\u0131n ikinci ana bile\u015fenidir. Bu gaz, standart s\u0131cakl\u0131k ve bas\u0131n\u00e7 (STP) ko\u015fullar\u0131nda gaz h\u00e2lindedir ve iki karbon ve alt\u0131 hidrojen atomundan olu\u015fur. Molek\u00fcl\u00fcn kimyasal yap\u0131s\u0131ndaki t\u00fcm ba\u011flar tek ba\u011fd\u0131r.<\/p>

Etan gaz\u0131n\u0131n kullan\u0131m\u0131<\/h2>

Etilen \u00fcretimi: Etan gaz\u0131, petrokimya end\u00fcstrisinde en \u00f6nemli temel bile\u015fiklerden biri olan etilenin \u00fcretimi i\u00e7in hammadde olarak kullan\u0131l\u0131r. Etilen, plastikler, re\u00e7ineler ve sentetik liflerin \u00fcretiminde ana bile\u015fendir.<\/p>

End\u00fcstriyel yak\u0131t: Etan gaz\u0131, baz\u0131 durumlarda farkl\u0131 end\u00fcstrilerde yak\u0131t olarak kullan\u0131l\u0131r. Yanma s\u0131ras\u0131nda y\u00fcksek \u0131s\u0131 enerjisi \u00fcretir ve bu, end\u00fcstriyel s\u00fcre\u00e7lerde kullan\u0131l\u0131r.<\/p>

So\u011futma proseslerinde kullan\u0131m: Etan gaz\u0131 d\u00fc\u015f\u00fck kaynama noktas\u0131 nedeniyle, end\u00fcstriyel so\u011futma sistemlerinde ve do\u011fal gaz\u0131n s\u0131v\u0131la\u015ft\u0131r\u0131lmas\u0131 (LNG) s\u00fcre\u00e7lerinde \u00e7ok d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda so\u011futucu olarak kullan\u0131l\u0131r.<\/p>

Laboratuvar ara\u015ft\u0131rma ve geli\u015ftirme: Etan, kimya ve gaz fizi\u011fi alan\u0131nda deneyler ve bilimsel ara\u015ft\u0131rmalar i\u00e7in standart bir gaz olarak kullan\u0131l\u0131r. Tan\u0131nm\u0131\u015f \u00f6zellikleri sayesinde, ara\u015ft\u0131rmac\u0131lar\u0131n kimyasal reaksiyonlar\u0131 incelemelerine yard\u0131mc\u0131 olur.<\/p>

Ev tipi so\u011futucuda etana kar\u015f\u0131 izob\u00fctan\u0131n \u00fcst\u00fcnl\u00fc\u011f\u00fcne dair d\u00f6rt neden<\/h2>

  1. \u0130zob\u00fctan, ev tipi so\u011futma sistemleri (buzdolab\u0131 ve dondurucular gibi) i\u00e7in ideal olan \u221211,7\u202f\u00b0C kaynama noktas\u0131na sahiptir. Buna kar\u015f\u0131l\u0131k, etan \u221288,5\u202f\u00b0C kaynama noktas\u0131 ile yaln\u0131zca \u00e7ok d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda end\u00fcstriyel so\u011futma uygulamalar\u0131 i\u00e7in uygundur.<\/p><\/li>

  2. \u0130zob\u00fctan daha y\u00fcksek enerji verimlili\u011fine sahiptir ve daha az enerji t\u00fcketerek ev cihazlar\u0131na yeterli so\u011futma sa\u011flar; bu da onu ekonomik h\u00e2le getirir.<\/p><\/li>

  3. Her iki gaz yan\u0131c\u0131 olmas\u0131na ra\u011fmen, izob\u00fctan daha az yan\u0131c\u0131d\u0131r ve d\u00fc\u015f\u00fck i\u015fletme bas\u0131nc\u0131 sayesinde etana k\u0131yasla daha g\u00fcvenlidir.<\/p><\/li>

  4. \u0130zob\u00fctan do\u011fal bir gazd\u0131r ve \u00e7evre dostudur; sera etkisi \u00e7ok d\u00fc\u015f\u00fckt\u00fcr ve ozon tabakas\u0131na zarar vermez. \u00c7evresel standartlar\u0131n s\u0131k\u0131 oldu\u011fu ev tipi sistemler i\u00e7in etana k\u0131yasla daha uygundur.<\/p><\/li><\/ol>

    Etandan etilen \u00fcretim a\u015famalar\u0131<\/h2>

    Etan veya etilen, \u00e7ift ba\u011f i\u00e7erdi\u011fi i\u00e7in y\u00fcksek reaktiviteye sahip doymam\u0131\u015f bir hidrokarbondur ve plastik ile polivinil klor\u00fcr (PVC) \u00fcretiminde kullan\u0131l\u0131r.<\/p>

    Etandan etilen \u00fcretimi d\u00f6rt a\u015famadan olu\u015fur:<\/p>

    Birinci a\u015fama: Hammadde haz\u0131rl\u0131\u011f\u0131<\/h3>

    Etilen \u00fcretimi i\u00e7in, etan hammaddesi buhar kraking s\u00fcrecine girmeden \u00f6nce safla\u015ft\u0131r\u0131lmal\u0131d\u0131r; bu, operasyonel sorunlar\u0131 ve verim kayb\u0131n\u0131 \u00f6nler. Bu haz\u0131rl\u0131k, k\u00fck\u00fcrt, karbon dioksit, su ve di\u011fer istenmeyen bile\u015fiklerin giderilmesini i\u00e7erir. Safla\u015ft\u0131rma s\u00fcreci genellikle etan gaz\u0131n\u0131n k\u00fck\u00fcrt ve karbon dioksiti tutmak i\u00e7in kimyasal emiciler veya gaz filtrelerinden ge\u00e7irilmesini ve nemin giderilmesi i\u00e7in kurutucular\u0131n kullan\u0131lmas\u0131n\u0131 kapsar. Bu ad\u0131mlar, kraking f\u0131r\u0131n\u0131nda ekipman\u0131n korozyonunu ve istenmeyen reaksiyonlar\u0131 \u00f6nler ve etilen \u00fcretimi i\u00e7in hammaddenin kalitesini optimize eder.<\/p>

    \u0130kinci a\u015fama: Buhar kraking<\/h3>

    Buhar kraking, etan gaz\u0131ndan etilen \u00fcretiminin ana a\u015famas\u0131d\u0131r ve y\u00fcksek s\u0131cakl\u0131k ve d\u00fc\u015f\u00fck bas\u0131n\u00e7ta etan molek\u00fcllerinin termal par\u00e7alanmas\u0131n\u0131 i\u00e7erir. Bu s\u00fcre\u00e7te etan, buhar ile birlikte kraking f\u0131r\u0131n\u0131na girer ve yakla\u015f\u0131k 850\u2013950\u202f\u00b0C s\u0131cakl\u0131kta ve 2 atmosferin alt\u0131nda \u0131s\u0131t\u0131l\u0131r. Su buhar\u0131 burada seyrelte\u00e7 g\u00f6revi g\u00f6r\u00fcr ve karbon olu\u015fumunu ile istenmeyen yan reaksiyonlar\u0131 \u00f6nler.<\/p>

    Y\u00fcksek \u0131s\u0131 etkisiyle etan molek\u00fcl\u00fcndeki karbon-hidrojen ba\u011flar\u0131 k\u0131r\u0131l\u0131r ve molek\u00fcl etilen ve hidrojen \u00fcretir. Kimyasal denklemi \u015f\u00f6yledir:<\/p>

    C\u2082H\u2086 \u2192 C\u2082H\u2084 + H\u2082<\/p>

    F\u0131r\u0131ndan \u00e7\u0131kan \u00fcr\u00fcnler, etilen ve hidrojenin yan\u0131 s\u0131ra az miktarda metan, propan ve di\u011fer daha a\u011f\u0131r hidrokarbonlar\u0131 i\u00e7eren bir gaz kar\u0131\u015f\u0131m\u0131d\u0131r. Bu \u00fcr\u00fcnler, daha fazla reaksiyonu \u00f6nlemek i\u00e7in hemen h\u0131zl\u0131 so\u011futma a\u015famas\u0131na girer.<\/p>

    Buhar kraking s\u00fcreci, etilen \u00fcretiminde y\u00fcksek verim ve bol ve ucuz hammadde (etan) kullan\u0131m\u0131 nedeniyle petrokimya end\u00fcstrisinde yayg\u0131n olarak kullan\u0131l\u0131r.<\/p>

    \u00dc\u00e7\u00fcnc\u00fc a\u015fama: H\u0131zl\u0131 so\u011futma<\/h3>

    Kraking f\u0131r\u0131n\u0131ndan \u00e7\u0131kan gazlar, yan reaksiyonlar\u0131 ve karbon olu\u015fumunu \u00f6nlemek i\u00e7in h\u0131zla so\u011futulur. Bu a\u015fama, su veya so\u011futma ya\u011flar\u0131 kullan\u0131larak ger\u00e7ekle\u015ftirilir. Ana ama\u00e7, istenmeyen reaksiyonlar\u0131 durdurmak ve etilen kayb\u0131n\u0131 \u00f6nlemektir.<\/p>

    D\u00f6rd\u00fcnc\u00fc a\u015fama: Ayr\u0131\u015ft\u0131rma ve nihai safla\u015ft\u0131rma<\/h3>

    So\u011futma i\u015fleminden sonra, gaz kar\u0131\u015f\u0131m\u0131 (etilen, hidrojen, metan ve di\u011fer hidrokarbonlar) ayr\u0131\u015ft\u0131rma kulelerine g\u00f6nderilir. \u00d6nce propan ve b\u00fctan gibi etilenden daha a\u011f\u0131r bile\u015fenler ayr\u0131l\u0131r. Ard\u0131ndan kriyojenik distilasyon (\u00e7ok d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda) ile etilen, hidrojen ve metan gibi daha hafif gazlardan ayr\u0131l\u0131r. Son a\u015famada, etilen kalan safs\u0131zl\u0131klardan temizlenir ve %99,9\u2019dan fazla safl\u0131\u011fa ula\u015farak petrokimya end\u00fcstrisi i\u00e7in haz\u0131r h\u00e2le gelir.<\/p>

    Etan, \u00e7evre i\u00e7in bir tehdit midir?<\/h2>

    Etan, g\u00f6rece zay\u0131f bir sera gaz\u0131d\u0131r ve metan ve karbon dioksite k\u0131yasla k\u00fcresel \u0131s\u0131nma \u00fczerinde daha az etkiye sahiptir. Bunun nedenlerinden biri, etan\u0131n atmosferdeki \u00f6mr\u00fcn\u00fcn yaln\u0131zca birka\u00e7 ay olmas\u0131d\u0131r; oysa metan ve karbon dioksit y\u0131llarca hatta on y\u0131llarca atmosferde kalabilir. Bu nedenle, etan\u0131n sera etkisi bu gazlara k\u0131yasla \u00e7ok s\u0131n\u0131rl\u0131d\u0131r ve iklim de\u011fi\u015fikli\u011fi \u00fczerindeki etkisi daha azd\u0131r.<\/p>

    Ancak etan, metan gaz\u0131na d\u00f6n\u00fc\u015fme potansiyeline sahiptir ve bu yolla \u00e7evre \u00fczerinde \u00f6nemli etkiler yaratabilir. Etan, atmosferde hidroksil radikalleri ile reaksiyona girerek metana d\u00f6n\u00fc\u015f\u00fcr; metan ise g\u00fc\u00e7l\u00fc bir sera gaz\u0131d\u0131r ve k\u00fcresel \u0131s\u0131nmada \u00f6nemli bir rol oynar. Ayr\u0131ca, do\u011fal gaz s\u0131z\u0131nt\u0131lar\u0131 ve end\u00fcstriyel s\u00fcre\u00e7ler gibi \u00e7e\u015fitli kaynaklardan etan sal\u0131n\u0131m\u0131, troposferde ozon seviyesinin artmas\u0131na neden olabilir. Bu tabakadaki ozon, insan sa\u011fl\u0131\u011f\u0131 ve bitkiler i\u00e7in tehlikeli bir kirletici olarak kabul edilir. Bu nedenle, etan kendi ba\u015f\u0131na zay\u0131f bir sera gaz\u0131 olsa da, dolayl\u0131 etkileri iklim de\u011fi\u015fikli\u011fi ve hava kalitesi \u00fczerinde kayda de\u011fer etkiler yaratabilir.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
