Does the vacuum need to be broken when shutting down the vacuum distillation tower? So why?
I think breaking the vacuum is done for safety reasons, to prevent the light components from rising further; by doing so, less of them remain in the towers, pipes, and equipment, which reduces the risks associated with inspections, maintenance, and other operations related to the light components in the tower. I’m not sure if this is correct:P
That’s right; upon deeper investigation, it indeed means that. But some operators simply can’t remember this. It can be explained like this: stop operations, that is, bring everything to a complete halt. First reduce the pressure by one level, then by another, and finally by a third – and that’s it. As for the disruption of the vacuum you mentioned, I define it as occurring in an accident situation, where steam is injected back directly. This happens mainly to prevent air from entering the system. Inside the tower, there are flammable and explosive gases, and the temperature is already high; all that’s needed is an ignition source, and that’s when things get dangerous
The vacuum must be broken; the pressure inside and outside is not equal, with external pressure being greater than internal pressure. As a result, the access hatch lid gets stuck and cannot be opened. Safety operations that are not conducive to maintenance.
Breaking a vacuum means not maintaining a vacuum state. For safety.
Yes, the most important thing is inhaling air; it causes an explosion
Breaking the vacuum is done for safety reasons, to equalize the pressure inside and outside the equipment. Easy for subsequent cleaning, inspection, maintenance, and disassembly.
The steps for shutting down a vacuum distillation tower include breaking the vacuum; failing to do so can cause damage to the equipment, so it is necessary to break the vacuum.
