| 1 | Integrated apparatus and process for high recovery of acetylene from the reaction of calcium carbide with water | US880933 | 1997-06-23 | US5955040A | 1999-09-21 | James W. Bunger; Christopher P. Russell; Jerald W. Wiser; Jesse C. Tsai |
| An apparatus for the manufacture of acetylene and hydrated lime from the reaction of calcium carbide and an excess of water is disclosed. A primary reactor for the initial reaction of the calcium carbide and water is disposed concentrically within a secondary reactor. Hydrated lime and unreacted calcium carbide flow directly from the primary reactor to the secondary reactor, where the carbide lime settles from the water and is removed. | ||||||
| 2 | Process for high recovery of acetylene and lime from the reaction of calcium carbide with water | US09399564 | 1999-09-20 | US06294148B1 | 2001-09-25 | James W. Bunger; Christopher P. Russell; Jerald W. Wiser; Jesse C. Tsai |
| 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of acetylene and hydrated lime from the reaction of water with calcium carbide is disclosed where the hydrated lime is withdrawn at a desired mass ratio of the hydrated lime to the calcium carbide feed.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. | ||||||
