Description
下記文献には反応装置の不連続挙動を減らし、固形物濃度を増加させるための2つの方法が開示されている。
最近の特許公報(下記特許文献5)に開示のスラリーループ反応装置では、一つのループにバイパスラインを有し、このバイパスラインは同じループの2つの位置を主ルートとは異なる移動時間を有する別の経路を介して接続することで、循環スラリーの均一性を改善している。
多数の移送ライン中の一つの移送ラインで閉塞が起こると、そのラインでの温度が低下し、移送ラインが縮むことになる。そうして、全ての移送システムが変形し、全ての移送システムに応力が加わり、最終的には設備が劣化し、および/または、破断する危険がある。
本発明の目的は、上記移送システムの流れを最適化することにある。
本発明の他の目的は、移送ラインの閉塞(詰まり)を減らすことにある。
これらの目的の少なくとも一つは、本発明によって少なくとも部分的に達成される。
本発明の好ましい実施例では、入って来る材料の速度がバイパスライン中の流れの方向と同じ方向にバイパスラインの軸線と平行な成分を有するような角度(11、12)で移送ラインがバイパスラインに結合される。この角度はバイパスラインに対して30〜75度、好ましくは約45度である。
本発明のシステムのダンプは圧力で制御される。圧力が設定点、一般に35〜45バールに達すると、沈澱脚からスラリーを放出するためのPTOバルブを作動して、材料は放出する。
反応装置は公知の任意の触媒系で運転できるが、メタロセン触媒系のような非常に活性の高い触媒系を用いるのが有用である。オレフィンの単独重合または共重合で使用できる。オレフィンはエチレンまたはアルファオレフィン、好ましくはエチレンまたはプロピレンであるのが好ましく、エチレンが最も好ましい。共重合でのコモノマーはC3〜C8アルファオレフィンが好ましく、ヘキセンが特に好ましい。
単一反応装置のバイパスで得られる効果に加えて、第1の反応装置の出口位置をバイパスラインに接続している移送ラインを短くでき、従って、第1反応装置から移送ラインへ入る未反応オレフィンの重合の危険を減らすことができる。第1の反応装置中のオレフィン濃度は少なくとも6重量%、好ましくは約8重量%の濃度に上げることができる。バイパスラインへの移送ラインの接続位置の間の間隔を十分にし且つ適当な角度で材料を入力することによって移送ライン閉塞の危険はさらに減少させることができる。
反応装置のパラメータは以下のとおり:
第1反応装置:
体積: 19m3
沈澱レグの数: 3
沈澱レグの内径: 19.37cm(標準8''パイプ)
沈澱レグの体積: 各30リットル
反応装置の内径: 45.56 cm(標準20''パイプ)
ポリエチレン製造量: 6.5トン/時
エチレン濃度: 6重量%
固形物濃度: 42重量%
第2反応装置:
体積: 19m3
沈澱レグの数: 4
沈澱レグの内径: 19.37cm(標準8''パイプ)
沈澱レグの体積: 各30リットル
反応装置の内径: 45.56 cm(標準20''パイプ)
ポリエチレン製造量: 4.5トン/時
エチレン濃度: 7重量%
固形物濃度: 42重量%
バイパスライン:
流れ分離点での角度=33度
流れ再合流新での角度=45度
バイパスラインの長さ=18m
バイパスラインの内径=14.64cm(標準6''パイプ)
バイパスラインは5つのベンド(湾曲部)を有し、3つのベンドは90度の角度を成し、一つのベンドは33度の角度で曲がり、一つのベンドは23度の角度で曲がっている。
3つの移送ライン(20、21、22)をバイパスライン(11)に対して45度の角度(11、12、13)でバイパスラインに接続し、移送ライン20と21との間は88cm、21と22との間は96cmにした。
各沈澱レグでのPTO弁のサイクル時間は一般に約20秒である。従って、各沈澱レグでは20秒毎の2回のダンプで約10kgのスラリー材料がダンプされる。
Claims (9)

各移送ラインをバイパスライン(10)へ結合する結合位置の間の間隔が少なくとも70cmであり、入って来る材料の速度がバイパスライン中の流れの方向と同じ方向にバイパスラインの軸線と平行な成分を有するような角度(11、12)で移送ラインがバイパスラインに結合されていることを特徴とする移送システム。 - 各移送ラインをバイパスラインへ結合する結合位置の間の間隔が少なくとも80cmである請求項1に記載の移送システム。
