Efforts to tighten communications of condition-monitoring instrumentation and data analysis software with CMMS and automation infrastructure, combined with the proliferation of wireless sensor systems and the drive to reduce manpower skill and time requirements, are bringing implementation costs down and drawing much attention to this approach. But should you implement it?
The basic principles of Lean Manufacturing date back at least to the 18th century. In Poor Richard's Almanack, Benjamin Franklin wrote, He that idly loses 5s. [shillings] worth of time, loses 5s., and might as prudently throw 5s. into the river. He that loses 5s not only loses that sum, but all the other advantages that might be made by turning it in dealing, which, by the time a young man becomes old, amounts to a comfortable bag of money.
Many companies decide not to build up certain capabilities in-house mainly because they dont have sufficient regular demand for them. Gamma scanning of distillation columns is a case in point, but on-site scanning specialists may be the wave of the future.
More attention to mercury and increased acceptance of predictive approaches is emerging. Such monitoring not only can keep plants on the right side of regulators but also can help provide insights for optimizing operation of equipment.
This article addresses cost estimating for capital projects on which an analyzer system is installed, through start-up and commissioning of the project, to the resultant lifetime cost savings that can be gained.

There are two main drivers for partial stroking of valves in safety systems: the desire to extend manual test intervals to as long as possible; and to reduce the amount of redundant hardware required for higher safety integrity levels. Like most things in life, it all boils down to one thing: trying to save money.
Understanding the fundamentals of fluid agitation can help meet the customers requirement and the processors need for efficiency. While portable mixers have been around for years, they often arent used to their full potential. Knowing the basics of mixing and flow patterns can help you get more out of your mixer.

In this month's installment of On the Bus, Contributing Editor John Rezabek predicts HART devices will work so well that your career may be over before you can justify the cost to replace them with fieldbus.
Understanding the purpose of control and safety systems helps users ensure each is appropriately optimized. The duties of the SIS are to protect the people, environment and assets against unsafe conditions.

More and more companies are placing greater emphasis on maintenance and seeking help from vendors to boost the effectiveness of their efforts, as some recent major investment decisions demonstrate. Many automation companies now are benefiting by building up asset management services alongside process control capabilities.
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.
Classic distributed control systems typically remain only in high-availability refining and power applications, but their strategies and capabilities persist in descendants and todays sophisticated networks.
Your current control system can probably do more than you think. Everybody can agree that diagnostics are a good thing they can identify problems early, and keep the plant running at peak performance. Learn how your existing control systems and analog instruments can deliver diagnostic capabilities, at a fraction of the cost of system or instrument replacements.
