CEMENT CLINKER LINE AND A METHOD FOR OPERATING A CEMENT CLINKER LINE
A method for manufacturing clinker comprising sintering raw meal in a kiln to clinker, preheating the raw meal in a preheater using a main flue gas stream from the kiln as heat source, dedusting the main flue gas downstream of the preheater at a temperature below the boiling point of mercury, thereby obtaining mercury loaded dust and withdrawing a bypass flue gas stream from the kiln, enables to efficiently remove the mercury from the process if mercury in the bypass flue gas is vaporized by injecting at least a fraction of the mercury loaded dust into the bypass flue gas stream. Subsequently, the bypass flue gas is dedusted and cooled down. Thereby, the mercury can be adsorbed by injecting an adsorbent like activated charcoal into the bypass flue gas. By subsequent removal of the adsorbent the mercury is finally removed from the process.
