Moreover, if the operating temperature is determined, the properties of the product oil obtained from the catalytic reaction can be determined.

Further, the main server 20 can estimate the life of the catalyst if the operating temperature of the catalyst having a known life is determined. The day when the life of the catalyst is exhausted is the day when the operating temperature of the catalyst exceeds the upper limit temperature of the apparatus. It is necessary to operate the apparatus at a higher temperature as the catalyst deteriorates. However, if the operating temperature exceeds the upper limit temperature of the apparatus, the apparatus cannot use the catalyst.

Since the sections 1 to 3 output the same value as the actual data, the values after the section 4 are values calculated as recommended operating conditions.
- the main server 20 proposes a processing amount larger than the processing amount of the scheduled operation condition as the sections 4 and 5. As the amount of processing increases, the operating temperature is proposed to be higher than the planned operating condition. As a result, when the apparatus is operated under the recommended operating conditions, the catalyst is deteriorated faster than when the apparatus is operated under the planned operating conditions. By using the catalyst deterioration function described above, the life of the catalyst can be accurately predicted in a relatively short time.

Abstract
Description
ユーザ端末にネットワークを介して接続されたサーバを用いて、原料油を触媒に通して生成油を得る装置の推奨運転条件を提供する方法であって、前記サーバに、
前記ユーザ端末から、前記装置の実績運転データと、ユーザの予定している前記装置の運転条件である予定運転条件と、少なくとも前記装置の使用期限を含むプラント情報とを取得させ、
前記実績運転データから前記ユーザに固有の触媒劣化関数を作成させ、
前記予定運転条件と前記触媒劣化関数に基づいて算出される前記予定運転条件で前記装置を運転した場合の触媒寿命よりも早く、かつ、前記装置の前記使用期限よりも遅く触媒寿命を迎えるような推奨運転条件を前記触媒劣化関数と前記プラント情報と前記予定運転条件とに基づいて算出し、前記ユーザ端末へ前記推奨運転条件を送信させる、装置の推奨運転条件を提供する方法。
また、上記の方法を実行するサーバ、およびサーバにより上記の方法を実行させるためのコンピュータ可読命令およびこれを記録する記録媒体が提供される。
図1は、本実施形態の推奨運転条件提供方法を実施するシステム構成図である。本実施形態の方法は、ユーザから製油所の装置の情報とユーザが予定している装置の予定運転条件とを取得し、これらの情報とベンチプラントデータベースから導かれる触媒寿命とから経済性指標などの優れた推奨運転条件を算出し、ユーザへ提供する。
メインサーバ20は単一のサーバで構成してもよいし、複数台のサーバで構成してもよい。また、ユーザ端末10とメインサーバ20を専用回線で接続してもよいし、インターネット回線で接続してもよい。メインサーバ20とデータサーバ30は一体の構成としてもよいし、別体の構成としてもよい。ユーザ端末10は、表示装置を一体又は別体に有している。
メインサーバ20は、CPU(Central Processing Unit)等のプロセッサ21と、各種プログラム(コンピュータ可読命令)が記録されたROM22(Read Only Memory)(非一時的コンピュータ可読命令記録手段の一例)と、各種データが一時的に記録されるRAM23(Random Access Memory)とにより構成されている。プロセッサ21は、ROM22に記録された各種プログラムから指定されたプログラムをRAM23上に展開し、RAM23と協働して以下に詳述する処理を実行するように構成されている。
装置には、運転温度の上限や原料油の上限処理量、触媒の充填量が決まっている。メインサーバ20は、ユーザにこれらの上限温度や上限処理量、触媒の充填量を入力させる画面をユーザ端末10に表示させる。
メインサーバ20は運転条件として、運転累積日数毎の処理量、液空間速度、水素分圧、水素オイル比、WABT(触媒層の平均温度)、を取得する。
メインサーバ20は原料油性状として、原料油の15℃における密度、硫黄濃度、窒素濃度、アロマ濃度、T50温度、T90温度、を取得する。
メインサーバ20は生成油性状として、得られた生成油の硫黄濃度を取得する。
なお、運転温度は、装置を運転する上で必須の情報であるが、実際のプラントの運営上は、仮温度を設定して運転した後に熟練者の感覚によって温度を微調整している。このため、ユーザは予定運転条件として運転温度を設定することが難しい。そこで本実施形態においては、予定運転条件としてユーザに運転温度は求めず、後述するように入力された予定運転条件からそれを実現する最適な運転温度をユーザに提供する。
触媒劣化関数とは、触媒の劣化度合いを示す関数である。触媒寿命は、触媒劣化関数に基づき算出することができる。触媒劣化関数は、脱硫触媒の劣化度を通油日数tの関数として表したものである。脱硫触媒の劣化度Φは、通油日数0日目の反応速度定数K0に対する通油日数t日目の反応速度定数Ktの比として定義される。すなわち、劣化度は、Φ=Kt/K0で表すことができる。触媒劣化関数については、本出願人が先に出願した日本国特願2016-247762を参照されたい。
さらにメインサーバ20は、既知の寿命を持った触媒の運転温度が定まれば該触媒の寿命を見積もることができる。触媒の寿命の尽きる日とは、触媒の運転温度が装置の上限温度を上回る日である。触媒が劣化するほど装置を高温で運転する必要があるが、運転温度が装置の上限温度を超えるとその装置でその触媒を使うことができないからである。メインサーバ20は、(触媒寿命の尽きる日)-(装置の期限日)を寿命余裕度として算出する。
メインサーバ20はこれらのいずれかの手法を使ってよりユーザにとって効率的に触媒を使用できる推奨運転条件を算出する。
また、メインサーバ20は、かかる推奨運転条件で装置を運転した場合の水素消費量と燃料消費量、およびそれらの費用を算出する。
これらを算出することで、どのモードで装置を運転すると経済的に最も優れているかをユーザにわかりやすく表示することができる。
ユーザ端末10にネットワーク40を介して接続されたサーバ(メインサーバ20)を用いて、原料油を触媒に通して生成油を得る装置の推奨運転条件を提供する方法であって、サーバに、
ユーザ端末10から、装置の実績運転データと、ユーザの予定している装置の運転条件である予定運転条件と、少なくとも装置の使用期限を含むプラント情報とを取得させ、
実績運転データからユーザに固有の触媒劣化関数を作成させ、
予定運転条件と触媒劣化関数に基づいて算出される予定運転条件で装置を運転した場合の触媒寿命よりも早く、かつ、装置の使用期限よりも遅く触媒寿命を迎えるような推奨運転条件を触媒劣化関数とプラント情報と予定運転条件とに基づいて算出し、ユーザ端末10へ推奨運転条件を送信させる、装置の推奨運転条件を提供する。
これにより、予定運転条件でプラントを運転した場合の触媒寿命よりも早く、かつ、プラントの使用期限よりも遅く触媒寿命を迎えるような推奨運転条件が得られるので、より効率的にプラントを運転できる。
これにより、ユーザは水素消費量と得率の少なくとも一方について、予定運転条件で装置を運転した場合と推奨運転条件で装置を運転した場合とを比較し、推奨運転条件を採用するか否かを簡単に判別できる。
これにより、ユーザは予定運転コストと推奨運転コストとを比較して、推奨運転条件を採用するか否かを簡単に判別できる。
なお、上述した実施形態においては軽油脱硫装置を例に挙げているため、軽油(UFT-LGO)留分が最も多くなる運転条件を得率優先推奨運転条件としたが、本方法を直接脱硫装置に適用する場合は重油留分が最も多くなる運転条件を得率優先推奨運転条件とする。本方法を間接脱硫装置に適用する場合は軽油留分が最も多くなる運転条件を得率優先推奨運転条件とする。本方法を灯油脱硫装置に適用する場合は灯油が最も多くなる運転条件を得率優先推奨運転条件とする。本方法をナフサ脱硫装置に適用する場合はナフサが最も多くなる運転条件を得率優先推奨運転条件とする。本方法をガソリン脱硫装置に適用する場合はガソリンが最も多くなる運転条件を得率優先推奨運転条件とする。
