There is a problem with the slurry pump
Thread Content
Dear sea friends! What causes blockages to occur before the slurry pump in the slurry system? What are the reasons that can cause blockage ahead of the slurry pump?
An increase in the slurry density, a rise in its solid content, insufficient stirring steam, and an excessive residence time of the slurry at the bottom of the tower all lead to increased coking, which accumulates in the pipelines ahead of the pump until blockage occurs~~~
Excessive residence time of the slurry leads to coking; since the pumps are not used alternately over long periods, the standby pumps must be kept in a preheated state and switched regularly.
High temperatures at the bottom of the distillation tower, long residence time of the slurry at that location, insufficient amount of steam for stirring – all these factors can lead to coking. Additionally, the absence of a filter screen at the bottom of the tower means that the formed coke particles accumulate in the pipes; once they gather into clumps, they can block the pipes
The slurry has a high solid content, and the requirement to periodically switch pumps and clean the filters is not fulfilled
The solid content of the slurry is too high, causing coking at the bottom of the distillation tower. Clogged filter screen, dosage of scale inhibitor
Dear sea friends: What causes blockage in the pipeline from the scale inhibitor dosing pump outlet to the slurry pump inlet? It should also be noted that there is no blockage between the scale inhibitor tank and the inlet of the scale inhibitor dosing pump
This problem could be due to 1. Sometimes, the scale inhibitor pump fails to deliver enough fluid, causing the slurry to flow back and block the pipelines; 2. Alternatively, it might be that the temperature of the scale inhibitor is too high, which over time leads to blockages in the pipelines
It’s likely due to coking; if the backup pump isn’t switched in for a long time or the filter isn’t cleaned for an extended period, blockages will occur over time
Pipeline blockage is likely caused by the gradual deterioration of scale inhibitors at high temperatures over time
Mainly, it is due to the high solid content of the catalyst. Secondly, it has a high density, due to coking
