摘要:
液氨是一种常见的化工原料，由于具有腐蚀性且易挥发，通常储存于耐压储罐中。以液氨泄漏后几种事故情况中的毒气扩散为研究重点，运用ALOHA软件对立式储罐的泄漏情况进行模拟，对泄漏点的孔径大小和高度这两个因素展开分析，分别改变泄漏点的孔径和高度，结合数据和效果图中泄漏范围变化的趋势，比较泄漏结果。分析结果表明，氨气扩散范围随着泄漏点孔径的增大而增大，在孔径达到一定值后保持不变，并随泄漏点距地面高度的上升而降低。
Abstract:
As a common raw chemical, liquid ammonia is usually stored in a pressure containing storage tank due to its nature of corrosive and volatile. In this paper, the toxic spread was discussed as the key point among the several accident situations by liquid ammonia leakage. ALOHA software was used to simulate the vertical storage tank leakage and extended to the factor analysis of pore size and pore height of leak point. The simulation results were compared in combing with the leakage range in design sketch by alternating the pore size and pore height correspondingly. Analysis results indicate that the scope of ammonia diffusion increases with the increase of pore size of the leak point and remains unchanged thereafter, but consistently decreases with the increase of pore height.
