Gasoline and naphtha unloading issues.
Thread Content
The main problem is that in the summer, there is a lot of gas during the unloading process. How to ensure safety when vapor and liquid are mixed.
1. Unload the truck in a sealed manner. 2. Fireworks are strictly prohibited to prevent static electricity. Under normal circumstances, it cannot be used on the crude oil unloading platform. It can be directly unloaded into the gasoline tank using the oil dump pump in the finished product workshop.
It is key to connect the electrostatic grounding device well, and to stop loading and unloading immediately when encountering lightning weather.
Unload the truck in an airtight manner, ensure good contact with the static electricity ground, and be careful not to bring in water. The receiving end should be filled with oil under the liquid. This post was last edited by czx000323 on 2009-4-2 23:40 ]
1. Crane the tube to the bottom 2. Connect the grounding wire 3. Protection and elimination of human body static electricity 4. Flow rate control when the oil contains water
To summarize: 1. Closely unload the truck to eliminate leaking steam 2. Ground static electricity to eliminate static electricity that may be generated during the unloading process 3. Strictly prohibit fireworks 4. Avoid bubbles when unloading the truck in thunderstorms and high temperature weather: There should be no problem of the crane pipe being inserted into the bottom of the tanker when unloading the truck. This is a problem during loading.
Another problem is that after the oil pulling vehicle arrives at the scene, it should be stationary for about five minutes before connecting the ground wire. Of course, the operator himself should pay attention to wearing labor protection and discharge static electricity before working.
