Low investment and maintenance cost
TurboSorp and Turbo-CDS systems are noteworthy for their compact designs. This allows for easier and lower cost installation in a plant. Fluidized bed technology does not employ rotating or wear parts, reducing the initial investment cost and the on-going maintenance costs. Due to the simplicity of the design of the system components, high levels of availability are typically achieved.
In certain cases, especially for smaller plants and for optimized investments, a dry sorption process based on lime or sodium bicarbonate is an interesting alternative to CFB-based flue gas cleaning technology. The process features a reactor, where the dry powdered additive is injected and mixed with the flue gas, and a downstream fabric filter.
Sodium bicarbonate for efficiency and low residue levels
The sodium bicarbonate process is used wherever residue quantities must be kept as small as possible. Due to the very high reactivity of sodium bicarbonate, only a small amount of it is required. The process is virtually independent of temperature and maximizes energy recovery.
