According to one embodiment the waste byproduct is gypsum. The gypsum can be obtained from a flue gas desulfurization process. According to another embodiment the waste byproduct is a calcium carbonate containing byproduct which is reacted with acid tar to produce calcium sulfide. The calcium carbonate containing byproduct can come from a Solvay process.</p> |
