Description
本発明の組成および方法が記述される前に、本発明は、記述される特定の分子、組成、方法論または手順に限定されるものではなく、これらは変動し得るものとして理解されるべきである。また、記述において使用される用語は、特定の種類または実施形態のみを記述するのが目的であって、添付の特許請求の範囲によってのみ限定される本発明の範囲を制限する意図のものではないことが理解されるべきである。
精製のために使用することができる。ある用途においては、精製ベッドから焼結多孔質コンポジットフィルター要素を分離してそれらを導管で互いに流動的に結合された別々のハウジング中に設置することが望ましい。そのような配置は、1つの構成要素の再配置またはその再生を容易にしおよびコストを低くする。装置構築の材料は、焼結多孔質コンポジット材料および/またはベッド材料が熱的におよび機械的に安定である広範囲の温度にわたってそれらをろ過または精製にとって有用なものとするために選択され得る。例えば、液体ヘリウム、液体窒素、液体二酸化炭素ならびに加熱された液体は、本発明の実施形態でろ過または精製され得る。好ましくは、液体または流体の温度は、焼結多孔質コンポジット材料フィルターまたはベッド材料の機械的性質または細孔径を変えない。好ましくは、温度は、約300℃以下である。本発明の要素の広範囲の熱安定性は、また、広範囲の粘度を有する流体の処理を可能とする。流体の粘度は、用途におけるフィルターおよびベッド材料に対して受容可能な流体流動と圧力損失を与える粘度であり得る。ある場合においては、液体の粘度は、加熱とそれに続くろ過または精製によって減少され得る。流体から汚染物質を除去するための方法は、図6において示される様にハウジングにおいて焼結多孔質コンポジット要素と材料のベッドを持つ装置を提供する工程および、汚染物質、例えば、炭化水素、水分、粒子またはこれらの組合せであってこれらに限定されない汚染物質を伴う流体を装置を通して流動させて流体から1種または複数種の汚染物質と粒子を除去する工程を含む。
ID0.850インチ、長さ6インチで、スチールマンドレル0.655インチ直径の金型を、28gの255ニッケル粉末(フィッシャーサイズ2.8ミクロン)で充填した。これは、5000〜6000psiで等方圧プレスされた。この素地形態の寸法は、OD:0.722インチ、ID0.655インチ、長さ6インチであった。素地形態およびマンドレルを、ID:0.800インチの新しい金型に注意深く置いた。この金型を7gの210Hニッケル粉末(フィッシャーサイズ0.3ミクロン)で充填し、7000〜8000psiで等方圧プレスした。この層状化された素地形態(寸法:OD:0.735インチ、ID0.655インチ、長さ6インチ、重量:35g)を、真空においてかつアルゴン中5%H2の還元雰囲気において、450〜500℃で30分間焼結した。焼結多孔質コンポジット管は最終のOD:0.685インチと全壁厚:0.036インチ(微細層、約0.003〜0.006インチ)を有していた。管は個々の管:長さ:1.38インチ、重量:7.5g、密度4.5g/ccに切断された。16cm2の流動領域を持つ乾燥切断管の気体流動テストは、それらが、20slpmの空気において27psiの差圧損失を有していたことを示した。
