Description
本発明は、高純度のメタンの液化天然ガス(LNG)ストリームとメタンより重い炭化水素を主に含む液体ストリームとを製造するために天然ガスまたは他のメタンリッチなガスストリームを処理する方法に関する。
図面の説明において、代表的なプロセス条件に関して計算した流速をまとめた表を提供する。この表では、流速の値(モル/時間)は、便宜上、最も近い整数に四捨五入した。表中に示された総ストリーム速度は全ての非炭化水素成分を含むので、炭化水素成分のストリーム流速の合計よりも通常大きい。表示温度は最も近い温度に四捨五入された近似値である。図示されたプロセスを比較する目的に関して実施したプロセスデザイン計算は、周囲からプロセスへ、またはプロセスから周囲への熱損失がないという前提に基づいている。市販の断熱材料の質がこの前提を非常に妥当な想定とし、当業者によって通常実施できるものとする。
発明の詳細な説明
実施例1
図1を参照して、本発明に従ったプロセスの説明から始める。この図では、天然ガス供給ストリーム中の大部分のエタンと重質成分とを含むNGL副生成物を製造するのが望ましい。本発明のこのシミュレーションにおいて、入口ガスはストリーム31として90゜F[32℃]及び1285psia[8,860kPa(a)]でプラントに入る。もし入口ガスが生成物ストリームを妨げて規格に合わせないようにするある濃度の二酸化炭素及び/または硫黄化合物を含む場合、これらの化合物は、供給ガスを好適に予備処理(示されていない)することによって除去する。さらにこの供給ストリームは、通常、極低温条件下で水和物(氷)が形成しないように脱水する。この目的に関しては、通常、固体乾燥剤が使用されてきた。
実施例2
LNG生成物に関する規格によって、供給材料ガスに含まれるより多くのエタンをLNG生成物中に回収できれば、本発明の簡便な態様を使用することができる。図3は、そのような別の態様を示す。図3に示されるプロセスで考えられる入口ガス組成と条件とは、図1のものと同一である。従って、図3のプロセスは、図1に示された態様と比較することができる。
実施例3
LNG生成物に関する規格によって供給ガス中に含まれるエタンが全てLNG生成物中に回収できるならば、またはエタンを含有する液体副生成物の市場がないならば、図4に示されているような本発明の別の態様を使用してLPG副生成物ストリームを製造することができる。図4に示されているプロセスで検討された入口ガス組成及び条件は、図1及び3のものと同一である。従って図4のプロセスは、図1及び3に示された態様と比較することができる。
実施例4
LNG生成物に関する規格によって供給ガス中に含まれるエタンとプロパンが全てLNG生成物中に回収できるならば、またはエタンとプロパンとを含有する液体副生成物の市場がないならば、図5に示されているような本発明の別の態様を使用して凝縮物副生成物ストリームを製造することができる。図5に示されているプロセスで検討された入口ガス組成及び条件は、図1、3及び4のものと同一である。従って図5のプロセスは、図1、3及び4に示された態様と比較することができる。
他の態様
当業者は、所定のプラントの場所での需要に最も合うように、NGLストリーム、LPGストリームまたは凝縮物ストリームを同時に製造できるように全てのタイプのLNG液化プラントで使用するために本発明を適合させ得ることを理解するだろう。さらに、液体副生成物ストリームを回収するために、種々のプロセス配置を使用できることを理解するだろう。たとえば図1及び図3の態様は、実施例1及び2に記載したようなNGLストリームよりもむしろ、液体副生成物ストリームとしてLPGストリームまたは凝縮物ストリームを回収するために適合させることができる。図4の態様は、実施例3に記載の如くLPG副生成物を製造するよりも供給材料ガスに含まれるC2成分のかなりの画分を含むNGLストリームを回収するため、または供給材料ガス中に含まれるC4及び重質成分だけを含有する凝縮物ストリームを回収するために適合させることができる。図5の態様は、実施例4に記載の如く凝縮物副生成物を製造するよりも供給材料ガスに含まれるC2成分のかなりの画分を含むNGLストリームを回収するため、または供給材料中に含まれるC3成分のかなりの画分を含有するLPGストリームを回収するために適合させることができる。
