Abstract
Description
可変ガイドベーンを有する遠心圧縮機を含むが、熱交換器の下流の再循環ラインにバタフライ弁が取り付けられていない、図1に示した構成を有する流動床反応器を用いて比較例Aの気相重合を遂行した。流動床反応器の設計パラメーターは次のようである:
反応器の径:4.0m
循環ループの径:0.2m
底部頂点を有する流動化グリッドの円錐状。
流動床反応器は、0.9m/sの流動床反応器内の流動化速度で作動するように設計された。
重合反応器の洗浄後、比較例Aの重合を繰り返した。しかし、流動床反応器は、再循環ラインへのキャリーオーバーを減少させるために0.7m/sの流動床反応器内の流動化速度で始動された。これによって遠心圧縮機の前後差圧は0.1MPaとなった。始動12時間後に、循環ループが閉塞され、これは循環ループでポリオレフィン粒子の不十分な循環が発生したということを示す。
重合反応器を洗浄した後、比較例Aの重合は繰り返されたが、ただし、これは流動床反応器の改質がなされてからこそである。改質された重合反応器は、可変ガイドベーンを備える遠心圧縮機が取り付けられるだけでなく、熱交換器の下流に設置されたバタフライ弁を備える、再循環ラインを含む図1に示した構成を有した。
