Flue-gas desulfurization - Wikipedia

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

Calcium Carbide Applications - Carbide Industries LLC

Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
