It seems in this case the pressure would have to be measured in very small section increments. I imagine it's like a clog forming in one particular section that could expand locally, while the rest of the pipe leg might not show an increase in pressure.
Maybe just have flow meters to detect dead legs. If a particular pipe section doesn't indicate any flow over some time period, assume it's a hazard condition and raise and alarm.
Another idea might be to find an ingredient which doesn't affect the product but will react when polymer forms, such that it can serve as an indicator that somewhere in the system there is a significant amount of polymer formed.
- kazinator 3y agoThere is the question of why does pressure rise that much? It seems that there is no pressure control behind the pumps. So that is to say, they use powerful pumps in some kind of open-loop operation, where the pressure is controlled by the lack of impedance to flow. It's as if, in electronics, we used a power supply with an insanely high unloaded voltage, and then just relied on that voltage dropping to an acceptable level due to system load. Then if the load is too low due to an open circuit, the voltage rises, and fries something that is powered from the same node. Why not control all the pumps so that the maximum pressure that can exist in the system is well within the capacity of the pipes and cisterns, even if everything plugs up.
- jefftk 3y agoI don't think that can be it: this was a dead leg, so a clog wouldn't increase pressure in the system elsewhere. Instead I think it has to be that popcorn polymer expands as it forms, directly putting pressure on the pipe in contact with it.
