Description
芳香族生産システムは、広沸点範囲コンデンセートを利用して、ベンゼン、トルエンおよびキシレンを含む芳香族生成物を生成する。広沸点範囲コンデンセートは、上流の源およびプロセスの外部からコンデンセート供給ライン10を通じて芳香族生産システム1に導入される。また、芳香族生産システム1は、下流の石油化学処理のために2つの有用な生成物流を通す。芳香族生産システム1は、芳香族生成物流12を通す。芳香族生成物流12は、実際には、混合された、または部分的に精製されたベンゼン、トルエン、キシレンおよびこれらの組み合わせを含む1つまたはいくつかの流れを含んでもよい。また、芳香族生産システム1は、LPG流14を通す。LPG流14は、水素分離および精製プロセスからの流出物であり、軽質アルカン(C1−4)および減量した水素を含む。LPG流14の水素プアーな混合ガスは、別の精製(例えば、水素抽出)に有用であり、芳香族生産システム1の外部の蒸気発生および発電のための高BTUボイラ供給として有用である。
2つの天然ガス生産井に由来する2つの有用な広沸点範囲コンデンセートの一例を表1に示す。先述の通り、広沸点範囲コンデンセートは、天然ガス貯留層、軽質コンデンセート貯留層、天然ガス液、シェールガスおよび他のガスなどの天然の炭化水素を含有する源、またはC3−12の範囲の軽質石油液体を生産する液化炭化水素を含有する貯留層に由来し得る。
本発明の実施形態にしたがい、HYSYS水素化処理モデルを用いて未精製品コンディショナーをモデル化した。このモデルは、炭化水素が関与する水素化処理反応および水素化分解反応の両方の速度過程を組み込むことができる。以前の試行から得られた未精製品コンディショナーパイロットプラント試験データに合うように未精製品コンディショナーモデルを校正した。未精製品コンディショナーモデルユニットを用いて、原油および天然ガスの精製および処理(アラブ・エクストラ・ライト(AXL)原油およびクフ(Kuff)ガスコンデンセート(KGC)のアップグレーディングおよび改良を含むが、これらには限定されない。)に関連する特性を評価および予測することができる。
