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. © 2021 China Safety Science Journal.
