Simulation Analysis of Propylene Storage Tank leakage Based on ALOHA Software

Abstract

Hazardous chemical leakage accidents occur frequently, and once it appears, it will create a great effect. If a more accurate risk assessment impact area can be made in advance, the preventions and controls will play an invaluable role. A propylene storage tank in an industrial park was taken to identify the lying accidents and the risk ranks with the method of Preliminary Risk Analysis. It was found that the propylene poisoning accident and the steam cloud explosion accident have a great threat to the surrounding. With the inputs of relevant parameters, ALOHA software was used to simulate each accident, and the propylene poisoning accident and the vapour cloud explosion accident threat areas were obtained. The simulation provides effective information for the prevention and control of leakage accidents in the propylene storage tank leaking, and provides a scientific guideline for its ordinary safety management.

Consequence modeling of liquefied petroleum gas accidental release from retail outlets in an African city residential environment

“…ALOHA model has been widely used for the simulation of hazardous gas dispersions. Previous studies have effectively integrated ALOHA for dispersion modeling and risk assessment purposes 7,8,16–21 . The model is based on the Gaussian dispersion model of constant and buoyant air pollution plumes that predict the concentration of gases with an increasing distance in the downwind direction.…”

Modeling the consequences of gas leakage and explosion fire in liquefied petroleum gas storage tank in Istanbul technical university, Maslak campus

“…can be produced by ALOHA. 7 In addition, ALOHA software is very easy to run and requires very less inputs, therefore its assumptions are sometimes deviate from practical scenarios. 8 In the present paper, the LPG storage tank and LPG filling station at Istanbul Technical University (ITU) Maslak campus was modeled using the ALOHA program in order to determine effects of LPG release and estimated losses.…”
