Wet flue gas desulfurization processes

Abstract

The wet flue gas desulfurization process is widely used for the treatment of exhaust gases in power stations. Due to its high level of effectiveness over the already available processes, it has also been the mostly preferred method by industry. Its high SO2 removal efficiency, wide applicability of absorption chemicals and the ease of the chemical process handling which does not require comprehensive konowledge are among the main advantages of this process. In this article, various wet flue gas desulfurization processes such as lime/limestone have beendiscussed.

Keywords

• Wet flue gas desulfurization, FGD, SO2 absorption, Lime/Limestone process.

Yaş baca gazı desülfürizasyon yöntemler

Abstract

Yaş baca gazı desülfürizasyon prosesi, güç santrallerinin atık gaz muamelerinde geniş çapta kullanılmaktadır. Kullanılan birçok proses arasında en etkili proses olduğundan, bu proses işletmeler tarafından tercih edilmektedir. Yüksek SO2 geri kazanımı, absorpsiyon kimyasallarının geniş uygulanabilirliği ve kimyasal prosesin yönetiminde büyük çapta bir bilgiye gerek duyulmaması bu prosesin avantajları arasında yer almaktadır. Bu yayında başta kireç/kireç taşı prosesi olmak üzere çeşitli yaş baca gazı desülfürizasyon proseslerinden bahsedilmiştir.

Keywords

• Yaş baca gazı desülfürizasyonu, FGD, SO2 absorpsiyonu, Kireç/Kireç taşı prosesi.
