For many cement producers, meeting legislated standards for acid gases, particularly SO2, means adding an extra step in the control system. The cost of this added step can be minimized by the recycling of the by-product in the cement production. This eliminates the cost of by-product disposal. When selecting a flue gas cleaning solution, reliability, ease of use and cost efficiency are the key considerations.
In some cases, when the cement kiln is burning alternative fuel, such as waste or RDF, the legislation is much stricter (see waste-to-energy section) and a very high removal efficiency is required.
Challenges
Most standard solutions include dry processes (dry sorbent injection) because of their flexibility, their simplicity and their lower investment cost while being reliable and efficient. Nevertheless, even if this cleaning step is outside the core business of the operator, process optimization is a critical aspect to be looked at.
