Flue Gas Desulphurization

CT-121 FGD Process

The emission of sulphur dioxide from oil and coal fired power stations can be reduced either by using expensive low sulphur fuels or by installing a flue gas desulphurisation (FGD) plant. The FGD plant represents a feasible and well-proven solution for maintaining fuel flexibility and at the same time meets legislation enforced emission standards.

The BWE CT-121 FGD process is a 2'nd generation wet limestone process that combines low investments and operation costs with easy and reliable operation. Through Chiyoda Corporation (www.chiyoda-corp.com) the inventor of the process, BWE/STF has the licence for the CT-121 FGD process on the European market.

The compact and simple design provides low construction costs and is an ideal option for plants with limited space available. The O & M cost is low due to low power consumption and easy operation with minimal staff requirement. Finally, the process offers high reliability where average of all existing plants exceeds 98%.

The results are:

• High, predictable SO2 removal efficiency up to 99%+
• High particulate removal performance exceeding 90%
• High quality gypsum by product
