Description
例えば、原料ガスとして、常温で高圧の都市ガス〔圧力:5.5MPaG 成分:メタン88%,エタン9%,プロパン2%,ブタン1%〕を用いる場合、供給された上記原料ガスは、熱交換器2で約−50℃に冷却された後、リボイラー1で約−55℃まで冷却され、その一部が液化する。ついで、原料ガス膨張弁3で膨脹した原料ガスは、約2.3MPaGまで圧力が低下し、さらに低温(約−90℃)となって、精留塔10に導入される。
原料ガスとして、上記実施例1と同様に、常温で高圧の都市ガス〔圧力:5.5MPaG 成分:メタン88%,エタン9%,プロパン2%,ブタン1%〕を用いて、供給された原料ガスを、熱交換器2で約−55℃に冷却した後、リボイラー1で約−60℃まで冷却(一部が液化)した。ついで、原料ガス膨張弁3で、実施例1とは異なる約0.2MPaGの低圧まで原料ガスを膨脹させた後、さらに低温(約−120℃)となった原料ガスを精留塔10に導入し、深冷分離させた。
上記第2実施形態の高圧天然ガスの分離装置を用いた高圧天然ガスの分離は、例えば、原料ガスとして、前記実施例1と同様の都市ガス〔圧力:5.5MPaG 成分:メタン88%,エタン9%,プロパン2%,ブタン1%〕を用いた場合、供給された上記原料ガスは、熱交換器2で約−40℃に冷却された後、リボイラー1で約−50℃まで冷却され、その一部が液化する。ついで、上記過冷却器4で約−60℃まで冷却された後、原料ガス膨張弁3によって約3.0MPaGまで膨脹して圧力が低下し、さらに低温(約−80℃)となって精留塔10に導入され、深冷分離される。
分離装置として上記第3実施形態の高圧天然ガスの分離装置を用いて、上記実施例3と同様の都市ガス〔圧力:5.5MPaG〕の分離を行う場合、まず、供給された原料ガスをリボイラー1で約+10℃まで冷却した後、熱交換器2’で約−20℃に冷却する。ついで、過冷却器4で約−60℃まで冷却された後、原料ガス膨張弁3によって約1.0MPaGまで膨脹して圧力が低下し、さらに低温(約−100℃)となって精留塔10に導入され、深冷分離される。
