Flow
More Flow
Causes
Valve failure
Worker left valve open
Consequences
Wrong Material in excess which affects purity
The Temperature of the mass leaving a heating vessel is too low
Pressure Build up in a reactor
Financial loss of feedstocks
Recomendations
Ensure workers have the correct training
Fit a Flow meter
High Flow alarm if applicable
Regualry inspect valves
No Flow
Cause
Complete Blockage
Complete Valve Failure
Worker did not open valve
Consequence
No final products are made
Financial loss
System overheats
Vaporization of toxic materials
Recommendations
Fit a flow gauge
Ensure workers have the correct training/checklists
Low flow alarm
No flow interlock which kills any process
Less Flow
Causes
Partial Blockage
Valve not fully opened
Valve failure
Consequences
Loss of final products
Financial loss
System overheats
Fluid is too hot
Feeds vapourise
Recomendations
Ensure workers have the correct training
Inspect valve regulary
Fit a flow gauge
Low Flow alarm if applicable
Reverse Flow
Consequence
No final products produced
Financial loss
A reaction occurs in a vessel that is not designed for the conditions
Risk of explosion and fire
Relase of toxic materials
Cause
Valve failure
Pressure drop in the feed vessel
Failure to open a valve
Recommendations
Install a no return valve
Install a level meter in the feed tank
Ensure workers have correct training
