It introduces the present main FGD techniques at home and abroad. The technical theory, technical process, adsorbent preparation and regeneration, by-product reuse of activated coke FGD have been introduced. Based on analyses the application of activated cokeFGD at home, combined with the projects, the paper compares the activated cokeFGD, limestone-plaster FGD,semi-dry FDG, ammonia FGD from techinic and economy. After comparation, it finds that activated cokeFGDhas lots of merits, and it can also be conserned with denitrification at the same time. In addition, the by-product has a large market need. The activated cokeFGD will be widly applicated with the extension of activated cokeFGD and continuouse improvement of activated coke. |
