Issues with heat exchangers are the second most common reason for slowdown / shutdown in the refining industry. Accurate control of the liquid level in the heat exchanger ensures energy efficient operation of the distillation column with the right quality at the top of the column
Reliable level measurement in important to ensure the heating coils are always covered with liquid, to prevent any overheating incidents. Guided wave radars is the recommended solution to have full control of your level measurement in the reboiler. This continuous level measurement technology can be combined with with point level switches for high and low level alarm.
The new Rosemount™ 2140 is the world's first wired HART® vibrating fork level detector for applications including overfill prevention, high and low level alarms, and pump protection. Providing reliable level detection of all liquids as well as sediments, the Rosemount 2140 offers greater ease-of-use and flexibility with smart diagnostics that continuously monitor electronic and mechanical device health, and a fully integrated remote proof-testing capability, helping to increase safety and efficiency of both plant and workers. The Rosemount 2140:SIS is certified to IEC 61508 (SIL 2) for safety-critical applications.
