Abstract:Through the addition of effluent container, rapid response pneumatic valve and orifice based on VSP2 (Vent Sizing Package 2), the blowdown tests of exothermic reaction runaway were conducted. The impact of heating power, initial fill rate, venting pressure, venting diameter and the reactant foaming property on the venting capacity and the effluent mass were investigated. The results indicate that the venting capacity decreases with the increase of heating power, and increases then falls with the rise of fill rate. In addition, the vent capacity decreases rapidly then increases slowly with the increase of venting pressure. Larger venting diameter leads to larger venting capacity. The effluent mass increases with the rise of heating power, fill rate, venting pressure and venting diameter. Foamy reactants can greatly decrease the venting capacity whereas increase the effluent mass.
