May I ask if the spherical tank can be unloaded simultaneously with the material return?

Here’s the situation: the propylene spheres A/B in our storage area are used, when in operation, one of them for feeding polypropylene, while the other is used for discharging polypropylene and unloading propylene. So, when these two tanks are in use simultaneously, Tank A is supplying material while the material being returned flows to Tank B. At this time, a truck carrying propylene arrives and needs to unload its cargo; can it be unloaded directly into Tank B? Before entering the tank, the return line and the propylene unloading line converge at the main pipe at the bottom of the tank before entering it. Please analyze it! ~~~Thank you
As long as the pressure is set properly, there should be no problems.
This needs to be determined by technical personnel, as some production processes are not that simple.
It is generally not recommended to do this, as a large difference in pressure can cause the material to flow back into the tank truck or into the system from within the tank truck, and it can also lead to errors in the measurement of the material. If it’s too urgent, it can be done in stages, which is safer.
