不同储存方式下液氨储罐泄漏环境风险性比较

Environmental Risk Comparison of Liquid Ammonia Storage Tank Leakage under Different Storage Style

文章针对液氨泄漏事故,对不同储存条件下泄漏量的大小、扩散范围、对人体造成危害的区域进行模拟预测和环境风险分析,对比说明了储存方式、储存条件对液氨储罐潜在环境危险性的影响。计算结果表明,常温高压储存较低温加压储存影响范围大,潜在环境风险性大,同时紧急撤离和疏散范围也较大。

In the paper, aiming at different ammonia leakage accident, different storage conditions on discharge leakage quantity, size, diffusion range, cause analysis simulation prediction and environmental risk hazard area to the human body, in contrast to the storage of liquid ammonia storage tank, storage conditions on the potential environmental risk impact. The calculation results show that, compared with normal temperature and high pressure storage at low temperature and low pressure storage range is large, the potential risk of environment, at the same time, emergency evacuation and evacuation range is bigger.
