摘要: 为评价油气回收工艺的本质安全性,考虑油气回收工艺流程简单、操作条件范围宽及操作状态不连续等特点,基于HAZOP-Aspen构建油气回收工艺安全评估模型。首先,采用危险与可操作分析(HAZOP)法分析油气回收工艺的风险,确定主要事故类型;然后,基于Aspen过程模拟,将工艺物流指数法与定量风险分析相结合,评估油气回收工艺的本质安全性;最后,以典型的冷凝+膜分离法油气回收工艺为例,应用该评估模型。研究结果表明:进料油气体积分数越高,本质安全程度越低;油气的爆炸极限普遍处于2%~10%范围内,随着进料油气体积分数的下降,工艺物流内各处的油气体积分数均更接近于爆炸上限范围。

Abstract: In order to evaluate inherent safety of oil and gas recovery process, a safety evaluation model was constructed based on HAZOP-Aspen considering characteristics of the process, including its simplicity, wide range of operating conditions and discontinuous operating conditions. Firstly, risks of the process were analyzed and main accident types were determined by adopting HAZOP. Then, based on Aspen procedure simulation, inherent safety was evaluated by a combined use of logistics index method and quantitative risk analysis. Finally, with typical "condensation + membrane separation" method as an example, the evaluation model was applied. The results show that the higher feed oil and gas concentration is, the lower inherent safety will be. The explosion limit of oil and gas is generally in the range of 2%-10%, and as concentration of feed oil and gas decreases, that of these in process stream will be closer to upper explosion range.

Key words: oil-gas recovery process, hazard and operability analysis (HAZOP), Aspen, process simulation, inherent safety, process stream index (PSI)
