Abstract
Description
1.プラントを始動する時の、SO2/SO3とSO3/H2SO4変換の温度差、及び付随する大気中への排気物質の排気限度の超過。
2.温度および関連するH2SO4の濃度に起因するプラントの全体的な腐食、及び付随する接触プラントの低い信頼性および急速な老朽化。
3.触媒の交換と修理のための高い運転コストと関連する高い資本コスト。
4.接触プラントは、3体積%を超す最低限のSO2の入口濃度を必要とし、それ未満ではH2SO4変換は進行しない。
5.システムの性質上、高温の触媒温度のために反応器はステンレス鋼から成り、比較的広い空間を必要とする。
この方法は以下の各ステップ(工程)から成る:
a.1gH2O/Nm3未満の水分含有量および少なくとも5ppmのSO2含有量を有する排ガスの供給、
b.第1の反応器への排ガスの導入、
c.活性炭触媒による第1の反応器中でのSO2からガス状のSO3への触媒変換、その場合、活性炭触媒上での触媒変換は100℃未満の温度で進行する、
d.第1の反応器から第2の反応器への予備精製された排ガスの導入、
e.第2の反応器中での水を用いてのSO3からH2SO4への変換。
