Accurate pH Analysis in Corrosive Fertilizer Materials
A major fertilizer producer struggled with achieving accurate, reliable pH measurement in a harsh and corrosive superphosphate production environment. Using rebuildable pH sensing technology, the producer has attained the delicate emissions control balance required, achieved a new level of measurement reliability and accuracy, and extended sensor lifespan, all while reducing overall maintenance cost.

Reliable, Long-Term Instrumentation Life in Corrosive Potash Environment
Potassium is often a key to high yield agricultural production; however it is not adequately present in all soils and must be mined from potassium chloride (potash). To be effective, potash must be separated from salt with chemicals – a process that is closely monitored for compliance with government regulations. With Foxboro instrumentation, a potash producer has been able to reliably meet all regulations, while also reducing maintenance and equipment costs.

Eastman Chemical
In harsh applications such as chemical and petrochemical processing, one plant-floor device that can represent significant costs is the sensor. Foxboro M&I helped Eastman Chemical Company significantly reduce equipment and related maintenance costs with its Foxboro® line of DolpHin™ series pH sensors. The Foxboro sensors provided Eastman with a solution that could withstand their challenging process applications and heighten process stability, accuracy, and performance.

ADM (Archer Daniels Midland Company)
Managing pH in high-temperature chemical applications is critical for consistent product quality, efficient process reaction, and compliance in environmental regulations. But because accurate measurement requires immersing pH sensors in hot, strongly acidic substances for extended time periods, companies have traditionally had to replace them every few days. Foxboro M&I provided ADM with a pH sensor that they can now use for months without replacing, thus significantly reducing equipment and labor costs, while maintaining high process quality standards.

Great Lakes Chemicals
Achieving accurate flow measurement at the beginning and end of batch runs is a common problem in industries ranging from chemical to food processing. Typically the flow meter starts empty, suffers the “hit” from the onset of process fluid, meters the bulk of the fluid, and then encounters slugs and two-phase flow at the end of the batch. However, the Foxboro Coriolis meter has overcome these challenging conditions and its installation at a Great Lakes Chemical facility has greatly reduced material loss, increased productivity through faster batch processing, and improved cost accountability of material.

Polyethylene Batch Processing
Polyethylene is the world’s most popular polymer; however difficult measurement of multiphase flow has been the source of a myriad of production problems, including poor product quality, wasted materials and higher energy costs. One leading chemical producer found a solution to problematic two-phase flow in batch processing with Foxboro digital Coriolis measurement, allowing them to enjoy reduced material loss, process downtime, and maintenance costs. The polyethylene producer found that the Coriolis transmitter demonstrated an incredible ability to accurately measure during the difficult stages of the batch process.
