Abstract : The feasibility of absorbing in diethylene glycol, SO2 from air containing 1000 ppm SO2 and desorbing the SO2 for recovery was confirmed. A design is given for use at new sulfuric acid facilities at munition plants. Development was discontinued because the tail gas could contain 0.1% of H2SO4, SO3 and NO sub X, which could react to form explosive dinitrate. (Author)
