Monitoring the level of coke drum bottoms in a delayed coker is among the most important process in a petroleum refinery. The LB 490 Tower-Sens detector (photo) has proven to be a reliable and cost-effective solution for this application because it is able to withstand the aggressive environment, which includes high temperatures and foam, extensive caking as well as high-pressure water jet. All components of the measuring system are mounted on the outer wall of the coke drum, thus unaffected by the harsh conditions inside. The Tower-Sens uses a detector length of up to 8 m, and continuously monitors foam as well as the coke level in the drum online and accurately. — Berthold Technologies GmbH & Co.
