KINETIC PARAMETERS OF THE PROCESS OF REGENERATION OF CARBONATE-SULPHATE MELT WITH NATURAL GAS
The kinetic parameters of the process of regeneration of a carbonate-sulfate melt with natural gas (reaction (1)) and a mixture of natural gas with air (reaction (2)) are determined in this work. It is shown that the mechanism of the process is described by a first-order equation. The activation energy of reaction (2) is four times lower than the activation energy of reaction (1). It has been established that the removal of sulfur from a carbonate-sulfate melt by bubbling with a mixture of natural gas and air can easily be carried out in the operating temperature range of an absorption column for purifying exhaust gases. The developed technology can become a practical and economical method of utilization of poor in sulfur content flue gases of thermal power plants and metallurgical enterprises.
