Chemical Processing Flow eHandbook: Monitoring Flow
The purpose of installing a flowmeter system is to accurately measure flow in a reliable manner. Issues related to physical properties, process parameters, electronic features and interconnections are often given much consideration. Relatively little emphasis, however, is given as to how well the flowmeter will perform its intended purpose. Adding to the confusion are the differences in how performance is expressed and the incomplete nature of the available information. Nevertheless, the quality of flow measurement should be a concern. This Chemical Processing eHandbook takes a look at technologies and solutions affecting flow including:

For chemical processors, changing process conditions demand quick responses in order to keep processing effective and to keep processes running properly. For processes undergoing such changes, accurate and timely measurements, such as vibration monitoring, redundant tank level measurement and steam header temperature profiling can be difficult to collect. In well-established plants it’s both very expensive and time consuming to get measurement points online using conventional wired instrumentation. Many processors are now turning to wireless devices that can supply data from numerous points that never could have been justified otherwise. In this Chemical Processing Wireless eHandbook we take a look at wireless technology solution successes:

Mixing Solutions and Slurries -- Effectively, Economically and Safely
Effectively mixing liquids and solids to create an optimal slurry is one of the perpetual challenges in the chemical industry. This case study demonstrates how an eductor-based mixing system can effectively handle a wide range of materials, utilizing the least amount of floor space, energy and human resources to achieve an optimized process. In addition, the eductor mixing system offers increased efficiencies over a conventional system of mixing by allowing solutions and slurries to be made on demand – as opposed to pre-mixed in large holding tanks. Another important benefit is the system limits exposure to operators, and mitigates issues of delivering solid material in a large vapor space. The design flexibility of an educator-based mixing system offers a high level of customization.
