摘要： A process for controlling the continuous production of acetylene and hydrated lime from the reaction of water with calcium carbide is disclosed where the hydrated lime is withdrawn at a desired mass ratio of the hydrated lime to the calcium carbide feed. The process is also controlled by regulating the temperature so that it is independent of the variations in the production of acetylene by regulating heat transfer to the environment at a rate to maintain a constant temperature in the reactor. Preferably, the reaction is controlled by withdrawing the hydrated lime slurry product at a rate low enough to maintain a slurry concentration of hydrated lime above about 14 weight percent.
