Abstract
Description
典型的には、軽質炭化水素ガスは、酸性ガスが少なくとも部分的に取り除かれて脱水されていてもよく、約C3よりも重い炭化水素ガスの少なくとも一部が取り除かれていてもよい天然ガスである。
図中、軽質炭化水素ガス液化システム及びプロセスが示されている。上述のように、このようなシステム及びプロセスは、LNGプロセスと呼ばれる天然ガス液化用に最も一般的に使用されている。図に示すように、液化プラント設備12には、3個の冷媒圧縮機14、16及び18により圧縮された冷媒が供給される(典型的には約1〜約75baraの圧力にて)。電気モータ20、22及び24は、シャフト26、28及び30を介して、これらの冷媒圧縮機を賦活するが、所望により他の結合を用いることもできる。3個の電気モータ及び冷媒圧縮機が説明として示されているが、より少数又はより多数を用いることもできる。さらに、液化プラント設備は、公知で使用し得る広範囲の軽質炭化水素ガス液化プロセスから選択される複数の冷凍ユニットを含み得ることは理解されたい。このようなプロセスは、単一ステージ又は多重ステージ冷凍容器などを用いて、多成分純粋冷媒、多成分冷媒及びこれらの組み合わせに至るまで変動し得る。
タービン54及び56は、軽質炭化水素ガス液化プロセスの運転用の電力を提供するように示されている。タービン54及び56は、当該分野で周知であるように、General electric Frame 7タービンなどのタービンである。これらのタービンは、典型的には、軸流圧縮機又は遠心圧縮機などの空気圧縮システムを含み、軽質炭化水素ガスを燃料とする。圧縮された空気は、ライン58及び60を通して充填され、炭化水素ガスは適切な圧力にて(典型的には約350〜800psi)ライン62及び64を通して充填され、燃焼ゾーン内で燃焼して、典型的には約2800(1538℃)〜約3000゜F(1649℃)の温度及び約350〜約800psiの圧力の熱い燃焼ガスを発生させ、タービンの入口(図示せず)に通過してタービンを駆動させ、熱い入口ガスは低圧高温ガス(典型的には約800(427℃)〜約1600゜F(871℃)の温度で、約15〜約100psigの圧力)として、それぞれライン80及び82を通して放出される。熱い排ガスは、熱交換器84に至り、ここで、ライン88を通して供給された水もしくはライン86を通して供給された低圧蒸気のいずれかと熱交換関係で通過して、ライン92を通して回収される高圧蒸気を発生させる。熱交換後の排ガス(典型的には約180(82℃)〜約200゜F(93℃)の温度にて)は、ライン90を通して排出するために適切な処理がなされる。高圧蒸気は、ライン100を通して回収される追加の電力を発生させるエネルギー回収発生器98にシャフト96を介してシャフト結合しているタービン又は膨張機94に通過する。この電力は、軽質炭化水素ガス液化プロセスを賦活する電力供給網に添加される。
