Level Measurement Solutions for Chemical Condensers

Condensation is the heat transfer process that changes a gas or vapor to a liquid. It is employed in the reflux process to improve the efficiency of distillation. Condensation can also be employed for producing saturated liquid products, for sub-cooling, or to serve an environmental or vapor recovery function. Condensation is carried out in a variety of configurations. By properly monitoring chemical condensers, plants can ensure that distillation and other processes run as efficiently as possible.

Magnetrol® has produced a brochure detailing different applications throughout the ethylene industry and exploring measurement challenges and solutions for each one. This blog post is part of an occasional series exploring each application in detai

Level Measurement Challenges and Considerations

In the distillation process, tower vapors are condensed prior to entering an accumulator. The condenser’s level can be used to control tower pressure where the liquid level set point serves as the manipulated variable (MV) for the pressure controller. Adjusting liquid level in chemical condensers changes the effective heat-transfer area.
