For more than six decades, a Canadian energy company has been delivering energy, including oil and gas, across North America. A large part of the company’s business is the operation of the world’s longest crude oil and liquids transportation system, conveying crude oil and other liquid hydrocarbons from the point of supply to refining markets in the midwestern U.S. and eastern Canada.

Last month’s column explored the effects that oversizing a pump has on the motor driving the pump, the adverse results of a pump no longer operating at its best efficiency point (BEP) for extended periods of time and situations in which a design margin could increase cost of ownership.

At every oil and gas facility, the ability to detect leaks and related problems quickly and accurately is a top priority. Leaking equipment can slow production, lead to costly damage and create unsafe working conditions.

In the event of seismic occurrences, structures and their components often resonate. Resonance occurs when the structure’s natural frequency coincides with the seismic activity’s frequency. For structures to be designed to withstand such occurrences, engineers perform an equivalent static analysis with forces proportional to the structure’s weight.

Q. How does a liquid’s viscosity affect the performance of rotary sealless pumps?

Vertical turbine pumps have multiple components that may make alignment complicated in American Petroleum Institute (API) and industrial applications. Tolerances cannot be made tight enough to ensure proper alignment because the required tolerances cannot be achieved by manufacturing accuracy alone.

As the U.S. Department of Energy (DOE) develops new regulations to improve pump performance and efficiency, the Hydraulic Institute (HI) has been on the forefront representing the pump industry. HI has been guiding the DOE through aligning its approach with current European Union (EU) regulations on water pumps.

STANTON, Neb. (Nov. 11, 2014)—Even as the Midwest cold dipped into the teens, the steel at Pump Station 38 was hot to the touch.

The most obvious positive manifestation of the ongoing oil and natural gas production boom in the U.S. can be seen at gas stations across the nation. At the end of January 2014, the average price nationwide for a gallon of gasoline was $3.28. One year later, the price for a gallon of gas had dropped to $2.04.

A common myth in the industry is that new pumps are shipped ready to “plug and play.” Assuming their new equipment has arrived fully equipped to run, end users often start new pumps with no oil in the bearings—one of the most common pumping mistakes.

Part 1 of this series (Pumps & Systems, March 2015) discussed what happens to a boiler feedwater (BFW) pump during plant transients.

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.

In today’s high-volume pumping applications, energy efficiency and cost control are more important than ever.

Last month’s column explored the effects that oversizing a pump has on the motor driving the pump, the adverse results of a pump no longer operating at its best efficiency point (BEP) for extended periods of time and situations in which a design margin could increase cost of ownership.
