A theoretical study of the interference from chlorine in the oxidative coulometric method for trace determination of sulphur in hydrocarbons.
A theoretical investigation has been made of the interference from chlorine in the oxidative coulometric method for trace sulphur determinations. A computer program (SOLGAS), based on the free-energy minimization principle, has been used to predict equilibrium compositions of the products resulting from combustion of a hydrocarbon sample containing sulphur and chlorine. The theoretical possibilities of overcoming the interference from chlorine and maintaining a high recovery of sulphur are described.
