摘要

Abstract

The gas-liquid phase equilibrium is used in controlling the nitrosation reaction process. Decomposition of nitrous acid and oxidation side reaction are suppressed in a closed reaction system. The system pressure is used as the criterion of the end of reaction

avoiding excessive feeding and reducing the decomposition of nitrous acid. The head space of the reactor is used as the gas buffer

stabilizing the feeding fluctuations and inhibiting the side reaction

decomposition of nitrous acid. Nitrogen oxide concentration is controlled at the minimum level. Thus the zero release of nitrogen oxide waste gas can be achieved without using any absorption process.
