Foam in chemical plants is usually a problem, generates additive costs, hinders the real control of the process, product analysis and availability of tanks, in addition to causing serious environmental and maintenance losses.

Did your pump ever cavitate because it was draining foam instead of liquid?

Check out how Alutal and Magnetrol International Incorporated can help you not “frown with anger” with foam problems!

Liquid tanks in chemical, refining, food, beverage and other process industries can have foam present, the dynamic nature of foam means there is no – “one-size-fits-all” measurement solution so, let us review challenges presented by foam and how to realize operational improvements through proper level instrumentation

There are 3 potential level measurements that involve a liquid tank with foam:

– Measuring the liquid level through the foam layer

– Measuring or monitoring the top of the foam layer

– Measuring the foam thickness

Choosing the right technology or multi-technology solution can mitigate overfill conditions or mishaps and costly environmental impact using the right solutions and applying best practices for measurement and detection can ensure optimal tank capacity utilization and boost process optimization.

Magnetrol understands the importance of accurate and reliable level measurement repeated foam-over conditions, can abstruct the passage to overflow vessels

Pumping foam instead of liquid can damage pumps – resulting in significant/avoidable production downtime and replacement parts costs proper monitoring of the top foam layer provides access to and utilization of a tank’s entire capacity, no longer you have to reduce tank levels to provide a buffer to optimize production throughput.

With large tanks severely under-filled this can result in considerable productivity gains. In addition, reliable measurement of foam location, thickness and level can reduce the costs associated with anti-foaming agents and chemical additives.

Let’s talk taking a multi-technology approach

“for a technology to be successful, there are a few questions to be answered”

– Which levels must be measured (liquid, foam, or both)?

– Do the levels need to be continuously monitore dor would a level switch suffice?

-What are the process conditions (temperature, pressure, corrosion, foaming)?

– What are the physical aspects of the tank (material, shape, obstructions, etc.)?

It is vitally important to understand and leverage the strength of a technology – while incorporating sound design principles to mitigate any shortfall
