In order to eliminate the SO 2, the flue exhaust gases from a coalfired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%–85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.
CE Concrete saw a window of opportunity in the 1980''s to join the greener power generation. With the help from wheel loaders and articulated haulers they are able to contribute to the greener power movement by extracting limestone that is used by coal power plants to scrub exhaust emissions and for dust control in underground coal mines to prevent explosions.
