| A method for generating acetylene from calcium carbide and recovering acetylene that would normally be lost during the process. The method includes putting calcium carbide into the purge bin of an acetylene generator; purging the purge bin with purge gas; transferring the calcium carbide to a hot aqueous bath in an acetylene generation chamber to generate acetylene; allowing a portion of the acetylene to move back into the purge bin where it mixes with the purge gas; passing the acetylene and purge gases through cold absorption water and allowing the absorption water to absorb some of the acetylene gas; transferring the absorption water back to the aqueous bath and allowing at least some of the acetylene to be released from the water as the temperature increases; recovering released acetylene; and using the aqueous bath to hydrolyze a subsequent batch of calcium carbide. | ||||||

| A process for carrying out highly endothermic chemical reactions wherein a reactive metal or a compound thereof is reacted with a source of carbon to form a carbon-containing derivative, preferably a carbide, in the presence of a molten metal. The sensible heat of the molten metal supplies the energy necessary for the reaction. | ||||||
