エチルベンゼンの吸収と分離塔にパッキングを設置する

2025-06-27

エチルベンゼンの吸収および分離塔は、通常、分離過程の要件、材料特性(エチルベンゼンと他の成分の沸点差、腐食性、粘度など)および運転条件(温度、圧力、処理能力など)に基づいて適切な包装材料を選択します。一般的な包装材料のタイプには、以下のものがあります:


1。構造化されたpacking

Structuredパッキングは、規則的な構造と整然とした配置を特徴とし、高い質量移動効率を備えており、高い分離精度を必要とするシナリオに適しています。1172 7 7 9 84001金属板段ボールpacking

Characteristics:薄い金属シートを段ボール状にスタンピングして作られ、段ボール板に小さな穴を開けて、質量移動面積、均一な流体分布、低抵抗、および高流量を増加させます。

Applicableシナリオ:エチルベンゼン分離では、材料の粘度が低く、強い腐食性がなく、高い質量移動効率が必要な場合(ベンゼンおよびトルエンからのエチルベンゼンの分離など)、このタイプのパッキングがしばしば選択されます。

Advantages:高い分離効率、タワーの高さを減らし、床面積を節約できます。1172 7 7 9 84001金属線メッシュ段ボールpacking

Characteristics:金属線メッシュで作られた波形構造で、比表面積が大きく、非常に高い質量移動効率、液体の滞留が少なく、抵抗が低い。非常に高い純度要件(例えば、微細化学製品の精製など)を伴う分離、または処理能力が小さいが高い分離精度が必要な場合。1172 7 7 9 84001注:コストが高くなります。材料に粒子が含まれている場合や汚れやすい場合は、閉塞の原因となる可能性があるため、注意して使用する必要があります。


2。ランダムpacking

Randomパッキングは、取り付けが簡単で、適応性が高く、処理能力が大きいシナリオや複雑な材料特性に適しています。1172 7 7 9 84001メタルステップリングpacking

Characteristics:一端がベル状に拡張された短い円筒形状で、より均一な流体分布、低抵抗、高流量、およびRaschigリングなどの従来のパッキングよりも優れた物質移動効率を提供します。

Applicableシナリオ:エチルベンゼンの分離では、材料の流速が大きい場合、動作の柔軟性が高い(負荷が変動する場合など)、またはパッキングを詰まらせにくい少量の不純物が含まれている場合、ステップリングを選択できます。1172 7 7 9 84001プラスチックポリプロピレン(PP)Pallリングpacking

Characteristics:プラスチック製で、耐食性、軽量、低コストで、リング壁に窓があり、流体の流れが良好です。

Applicableシナリオ:エチルベンゼン材料に酸性成分(腐食性ガスなど)が含まれている場合または動作温度低いです(ポリプロピレンは約100°C以下の温度に耐えることができます)、プラスチックPallリングは、機器の腐食リスクを低減するために使用することができます。1172 7 7 9 84001セラミックRaschigリング/ステップリングpacking

Characteristics:セラミック製、それは強い耐食性と高温耐性を持っていますが、より低い空隙率と高い抵抗を持っています。

Applicableのシナリオ:エチルベンゼン材料が強い腐食性(無機酸を含むなど)と高温を有し、物質移動効率要件に基づいて慎重に選択する必要がある特殊な条件でのみ使用されます。
