Perspectives: Making it Work

Special Seal Surmounts Latex Problem

Custom design provides a cost-effective long-term solution for pumps

By Jürgen Mews, EagleBurgmann Germany

Preventing problems with mechanical seals used on pumps handling synthetic polymer dispersions (latex) is a major engineering challenge. Essentially, difficulties arise because the polymer dispersions are not thermodynamically stable and tend to coagulate. Polymer particles form compact agglomerates that quickly can bring the process to a halt.

Title

The intrinsically safe fieldbus has arrived

Fieldbus has proven its merit in bringing projects online more efficiently, allowing better diagnostics, and control, and reducing maintenance costs and inventories. However, it has been limited in intrinsically safe services. At last, technology has come through once again with a solution. The capacity barrier of FISCO has now been significantly surpassed by a novel split architecture design that has already proven itself in the field.

pH sensor stands up to tough conditions

Design provides improved reliability in a polymer-precursor batch reactor. Sensors must respond quickly and survive a harsh environment. Poor probe reliability can make the difference between a process that makes money and one that doesn’t.
