Uniform corrosion from acidic process fluid (H2S, CO2, organic acids)
Pitting corrosion at the gas-liquid interface zone
Preferential corrosion at weld heat-affected zones
Erosion-corrosion at the inlet nozzle from high-velocity wet gas flow
Level transmitter bridle (standpipe) fouled with paraffin or scale causing sluggish response
Level control valve stuck or plugged preventing drainage
Transmitter calibration drift from temperature or process fluid density change
Float or displacer mechanism failed in differential pressure or displacer-type instruments

How to fix liquid level control failure on a Sulzer KnitMesh process separator
Level control failure risks liquid carryover into the gas outlet or loss to the flare. Check the level transmitter, bridle, and control valve as the first three steps.
How to diagnose mist eliminator plugging on a Sulzer KnitMesh separator
A plugged mist eliminator causes liquid carryover and high pressure drop. Trend the differential pressure and plan an inspection or cleaning at the next scheduled outage.
How to plan an internal corrosion inspection on a Sulzer KnitMesh process separator
A scheduled corrosion inspection confirms remaining wall thickness and corrosion rates. Measure ultrasonic thickness at the inspection grid points and compare to the minimum allowable wall.
