Controlling A Piping System

This is a continuation of a series of articles on understanding the operation of fluid piping systems. We previously discussed how a piping system consists of three elements working together to achieve the system’s objectives. The pump element adds energy to the fluid to overcome the static and dynamic head of the process elements in the system. These process elements, such as tanks, heat exchangers, strainers, pipelines, valves and fittings, require a certain amount of energy to deliver the fluid to make the products or provide the services at the desired production rate.

System Approach & Modeling Lead to a Reduced Impeller Diameter

In industries where pumps are widely used, significant savings may be achieved with a better understanding of how the system can be optimized. In my discussions with personnel at process plants, an individual or small group is usually responsible for reducing energy consumption for the plant. This process may result is some savings in electrical power consumption, but additional improvements are overlooked because the focus is not on the total picture.

Pump System Improvement

In this month’s column, we will look at a pressurized forced main waste treatment system in an industrial process facility. A major facility expansion was completed consisting of a new research and development center, and new offices for the administrative, financial, maintenance and engineering departments. In addition, the expansion affected the maintenance shop, doubling the building size.

Assessing Fluid Piping Systems

I have been involved in assessing piping systems since the early 1980s and the release of our pump selection and evaluation software. The program uses electronic pump catalogs created and distributed by the pump manufacturer. With a pump rep, I made sales calls to engineering firms in Vancouver, Canada, to illustrate how they could calculate the annual operating cost for various pump models under consideration.
