Description
残留石油留分をディレードコーキングするプロセスは、しばらく前より石油精製産業で用いられてきている。このプロセスにより、重油留分を、例えば、コーキング産物由来の液化石油ガス(LPG)、ナフサおよび軽油など、より高付加価値を有するより軽質の生成物に転化させることが可能になる。
燃料ガス、LPGおよび軽質ナフサ(分留塔の頂部から出ていくため、先行技術では炉頂ガスとして知られている)の混合物、並びに
重質ナフサ、コーキング産物由来の軽質軽油(LGO)、およびコーキング産物由来の重質軽油(HGO)の副産物
に分離される。
コークス形成がコークスドラム内のみで発生し、炉の管内では発生しないことが望ましい。したがって、炉の管内でのコークス形成を最小にするため、混合原料油を炉内に数分だけ滞留させ、且つ、
反応の進行とコークスドラムの排出管内での起こり得る望ましくないコークスの付着を防ぐために、軽油および/または残油の流れを用いて急速冷却(急冷)を行う。
本発明の主題である、改質原料油を用いたディレードコーキングするプロセスでは、ディレードコーキングユニットの原料油に対する改質によって、ディーゼル油の体積を最大にし、生成されるコークスの体積を最小にする解決策を検討する。
本発明の主題である、改質原料油を用いたディレードコーキングするプロセスの説明を、下記の図に基づいて、それぞれの構成要素の識別に従って行う。
本発明は、以下の実施例によって理解を深められよう。しかし、実施例は本発明を限定しない。実施例では、表1による特性を有する常圧残油(AR)、減圧残油(VR)、および重質減圧軽油(HGO)を用いている。
減圧残油をコークスリサイクルからの重質軽油なしでディレードコーキング試験ユニットで処理した。炉の温度は500℃であり、コークスドラムの頂部での圧力は2kgf/cm2gであった。ディーゼル油については51.3%、コーキング産物由来の重質軽油については20.2%の体積収率を得た。コークスの質量収率は24.5%であった。
減圧残油を、体積で20%の重質減圧軽油と混合した。混合原料油をコークスリサイクルからの重質軽油なしでディレードコーキング試験ユニットで処理した。炉の温度は500℃であり、コークスドラムの頂部での圧力は2kgf/cm2gであった。ディーゼル油については52.2%、コーキング産物由来の重質軽油については23.2%の体積収率を得た。コークスの質量収率は20.3%であった。
常圧残油をコークスリサイクルからの重質軽油なしでディレードコーキング試験ユニットで処理した。炉の温度は500℃であり、コークスドラムの頂部での圧力は2kgf/cm2gであった。ディーゼル油については53.5%、コーキング産物由来の重質軽油については27.7%の体積収率を得た。コークスの質量収率は13.5%であった。
