Improving Valve Total Cost of Ownership

Emerson's Christof Lindner

An important metric for driving continuous improvement in the process industries is total cost of ownership (TCO). One of the methods to lower these costs is to standardize and limit variations on the plant equipment across sites and geographic locations.

In a Flow Control magazine article, Improve Total Cost of Ownership with Valves, Emerson’s Christof Lindner shares ways that standardizing equipment, suppliers, programs and processes can drive down TCO.

Flow Control: Improve Total Cost of Ownership with ValvesChristof explains the purpose is to:

…focus on the goal of increasing efficiency and reducing TCO related to the procurement, installation and maintenance of valves and controls equipment, and inventory control processes across multiple plant sites.

Valves and control equipment is an important area to address, given their impact on reliable and efficient operations. The journey toward standardization…

…begins with an evaluation. Once the evaluation is completed, a team then works in collaboration with the customer to develop and implement a customized standardization plan across their facilities over a period of several years.

Cost savings can occur through streamlined specification and equipment ordering, quicker access to spares, use of higher reliability products, standardized lifecycle support, more consistent team members, and better application fit of the standardized equipment.

Christof outlines three components to effective standardization: Continue Reading

#POWERGEN 2017 Preview: Flexible Operations

Emerson's Douglas Morris

Author: Douglas Morris

The new plants that are coming online today are already designed for fast start and flexible operations. With the changing generation mix, being able to move a unit is essential as fleets dispatch more renewables. But what about older plants that were designed to operate as baseload generation?

Sometimes units must be mechanically retrofitted to be able to better participate in the market, but sometimes it may just require some targeted automation improvements. So where should utilities start? Continue Reading

Plan for PID Control Differences in Control System Migration Projects

The typical lives of industrial control systems (ICSs) are measured in decades. Even so, the time comes when reliability and securing replacement parts becomes nearly impossible given the rapid advancement of technology.

There is much to plan and do when the time comes to migrate and modernize the control system. In a Chemical Processing article, Avoid Startup Surprises in Control System Migration, Emerson’s Laurie Ben, Aaron Crews and James Beall share guidance and recommendations on how to avoid common pitfalls.

Chemical Processing: Avoid Startup Surprises in Control System MigrationThey open describing a hot cutover to a new distributed control system (DCS) gone awry:

The operator puts the control loops in the proper mode. Everything looks good initially. Thirty minutes later, though, the key loops on the column start to cycle. Soon, the top and bottom composition (temperature) loops have hit their respective alarm limits, indicating near out-of-spec products. The operator takes manual control trying to recover. It’s too late. The overhead and bottom streams have switched to recycle mode.

A common cause for this situation is the difference in proportional-integral-derivative (PID) control algorithms between the legacy and modern control system. Part of the planning effort is to not only understand and apply the additional power in modern PID control algorithms, but also understand and adjust for the differences. Continue Reading

Bulk Liquids Terminal Digital Transformations

Bulk liquids terminal operators have largely relied on a mix of automated and manual operations to perform their role in the liquids movement supply chain. This mixed mode of operations means there are holes or delays in data to aid in decision making, which makes the terminal operate less efficient, reliable, and more prone to operational risks.

The 2nd Tank & Terminal Tech Asia conference will be held November 28-29 in Kuala Lumpur, Malaysia. The focus of the conference is on embracing innovation to improve operations. Emerson’s Jonas Berge will present, Digital Transformation for Operational Certainty. Here is the abstract of his presentation:

Emerson's Jonas Berge

Accurate inventory management and custody transfer with an accurate tank gauging system is fundamental. Beyond this, terminals and other sites with tank farms must ensure storage tanks, pumps, valves, and heat tracing systems are functional when product is received or to deliver. Pipe integrity must be ensured, overfills and spills often caused by wrong valve-lineup must be avoided. This must be achieved without stretching personnel. Manual data collection is too infrequent and therefore not very effective in preventing equipment failure, and it is very time consuming. Operators often have no visibility of safety shower activation or tank leaks. Continue Reading
