A flash explosion occurred during the loading of liquid asphalt
Thread Content
After temperature exchange, the liquid modified asphalt in our plant reaches 210 degrees. A flash explosion occurred at the loading port during loading; there was no visible flame at that time. The required loading volume is 50 tons, and it usually takes two and a half hours to complete the loading. At one and a half hours into the loading process, a flash explosion occurred at the loading port. What could be the cause of this?
It’s probably caused by static electricity! Is the tank truck grounded during loading?
There is volatilization of light components inside, and during loading the container was open, allowing air to enter. As mentioned above, static electricity may have been generated, or someone might have carried static electricity while operating it, or a small amount of sparks could be produced when an iron cover is placed on it.
Reply to 2# hjkupc: Thank you, we have completed the static grounding
Two flash explosions also occurred while we were purging the tank truck with steam, the cause of which is unknown.
The presence of water could also be a factor, as well as an overly fast loading speed
