Coke drums

Density, level measurement and point level detection in coke drums

Process data

Measuring task:
Density and level measurement, point level detection
Measuring point:

Special challenges:
High temperature, heavy foam, buildup


Delayed coking units are a critical step in the refining process - this is where downtime, inefficiency, and overfill are not an option. They generate extreme heat during operation and are very large vessels. By monitoring upper vapour phase density, operators can reduce antifoam carry-over and improve continuous productivity with accurate level measurement.

Your benefit

Safe measurement even under extreme conditions
Cost effective
Reduced need of foam agents thanks to continuous foam monitoring
User friendly
Easy installation
