May I ask the experts for solutions to the problem where the seal leakage inlet of the bottom pump cannot be cut off?
Why can’t it be cut out? Hand valves are installed at both the pump inlet and outlet
1 Assess the scale of the fire and determine whether it can be brought under control. 2 It is not possible to cut off the flow; the fire is too intense to approach the area, so the only option is to shut it off at the nearest inlet or outlet valve (such as the bottom-reduction extraction valve, or the inlet valve of the first heat exchanger at the outlet of the bottom-reduction pump), resulting in an emergency shutdown of the plant. 3 If the leak is minor or the fire can be controlled, extinguish the fire, find ways to seal the inlet and outlet valves and repair the pump; if it’s impossible to seal them properly and no solution can be found, then shut down operations as planned.
