Etil benzen emme ve ayırma kulesine paketleme montajı

2025-06-27

Etilbenzen emme ve ayırma kuleleri tipik olarak ayırma işlemi gereksinimlerine, malzeme özelliklerine (etilbenzen ve diğer bileşenler arasındaki kaynama noktası farkı, aşındırıcılık, viskozite vb.) ve çalışma koşullarına (sıcaklık, basınç ve işleme kapasitesi gibi) göre uygun paketleme malzemelerini seçer. Yaygın ambalaj malzemeleri türleri şunları içerir:


1. Yapılandırılmış packing

Structured ambalajı, yüksek kütle transfer verimliliğine sahip düzenli yapıya ve düzgün düzenlemeye sahiptir ve bu da onu yüksek ayırma doğruluğu gereksinimlerine sahip senaryolar için uygun hale getirir.

Metal levha oluklu packing

Characteristics: İnce metal levhaların oluklu şekillere damgalanmasıyla yapılır, oluklu levhalar üzerinde küçük delikler ile kütle transfer alanını, tek tip sıvı dağılımını, düşük direnci ve yüksek akış hızını arttırır.

Applicable senaryoları: Etil benzen ayrımında, malzeme viskozitesi düşükse, güçlü bir aşındırıcılık yoktur ve yüksek kütle transfer verimliliği gerekir (etilbenzenin benzen ve toluenden ayrılması gibi), bu tür ambalajlar genellikle seçilir.

Advantages: Yüksek ayırma verimliliği, kule yüksekliğini azaltabilir ve zemin alanından tasarruf edebilir.

Metal tel örgü oluklu packing

Characteristics: Oluklu bir yapıda metal telden yapılmıştır, geniş bir yüzey alanına sahip, son derece yüksek kütle aktarımı, küçük, sıvı ve düşük direnç senaryoları için uygundur

Applicable : Son derece yüksek saflık gereksinimlerine sahip ayırma (ince kimyasal ürün saflaştırma gibi) veya işleme kapasitesi küçük olduğunda ancak yüksek ayırma doğruluğu gerektiğinde.

Notlar: Daha yüksek maliyet. Malzeme parçacık içeriyorsa veya kirlenmeye eğilimliyse, tıkanmaya neden olabilir ve dikkatli kullanılmalıdır.


2. Rastgele packing

Random ambalajının kurulumu kolaydır, güçlü uyarlanabilirliğe sahiptir ve büyük işleme kapasitesine veya karmaşık malzeme özelliklerine sahip senaryolar için uygundur.

Metal adım halkası packing

Characteristics: Bir ucu çan şekline genişletilmiş kısa silindirik şekil, daha düzgün sıvı dağılımı, düşük direnç, yüksek akış hızı ve Raschig halkaları gibi geleneksel ambalajlara göre daha iyi kütle transfer verimliliği sağlar.

Applicable senaryolar: Etil benzen ayrımında, malzeme akış hızı büyükse, çalışma esnekliği yüksektir (örneğin yük dalgalandığında) veya ambalajı tıkamaya eğilimli olmayan az miktarda kirlilik içeriyorsa, adım halkaları seçilebilir.

Plastik polipropilen (PP) Pall ring packing

Characteristics: Plastikten yapılmıştır, iyi akışkan senaryoları için duvarlarda pencereler bulunan aşınmaya dayanıklı, hafif ve düşük maliyetlidir.

Applicable: Malzeme, asitli gazlar (örneğin çalışma sıcaklığı) içeriyorsa Düşük (polipropilen yaklaşık 100C 'nin altındaki sıcaklıklara dayanabilir), ekipman korozyon risklerini azaltmak için plastik Pall halkaları kullanılabilir.

Seramik Raschig halkası / adım halkası packing

Characteristics: Seramikten yapılmıştır, güçlü korozyon direncine ve yüksek sıcaklık direncine sahiptir, ancak daha düşük bir boşluk fraksiyonuna ve daha yüksek dirence sahiptir.

Applicable senaryoları: Sadece etilbenzen malzemesinin güçlü aşındırıcılığa (inorganik asitler içeren gibi) ve yüksek sıcaklığa sahip olduğu özel koşullarda kullanılır ve kütle transfer verimliliği gereksinimlerine göre dikkatlice seçilmelidir.
