Capability Spotlight: Optimize Energy Efficiency

It’s estimated that 85% of pumps are not optimized to their systems, costing end users both efficiency and reliability. To achieve operational excellence and reduce environmental impact, assessing and improving our systems is essential.

Many OEMs focus on the initial pump design and providing a higher peak efficiency. While this can provide energy savings, it misses some of the greatest gains available. With our history in developing solutions for the aftermarket, Hydro approaches energy efficiency differently. Our unique experience as a brand-agnostic company focused on end users’ existing installed equipment has provided us with insight into improving equipment performance by understanding how it operates as a part of the greater system. This has allowed us to provide significant energy savings for our partners, as shown in successful cases such as this case study published in World Pumps magazine.

Hydro’s Energy Edge program takes advantage of our in-house engineering, field testing, remanufacturing, and parts capabilities to provide an end-to-end solution to improve energy usage and reliability. The process starts with getting the necessary design and operation data to perform a comprehensive analysis of current performance and identify opportunities for improvement. Depending on the findings, solutions can range from system operations recommendations to hydraulic modifications to a completely redesigned drop-in replacement. By providing a custom solution instead of an off-the-shelf replacement, Hydro not only optimizes performance, but minimizes cost, lead time, and risk by ensuring that the solutions fits into the existing equipment footprint.

Some of the aspects of an energy optimization project may include:

  • Energy Savings Audit: Field performance testing provides a performance baseline and identifies areas where improvements can be made
  • System Analysis: Using system design experience and AFT Fathom hydraulic analysis software, Hydro’s engineers model and simulate fluid flow through the system to accurately predict system behavior and optimize performance.
  • Hydraulic Modification: Modification to existing hydraulic components or design of new components provides hydraulic performance optimized to meet system needs. Our hydraulic specialists use both design knowledge and CFD analysis to provide the best fit design for the application
  • Equipment Remanufacturing and Parts Supply: Modifications are implemented through Hydro’s service center network, ensuring oversight and communication with the engineering design team. New cast parts are provided by our Parts Solutions division, ensuring control over parts quality and lead time.
  • Performance Testing: Testing in our HI-certified performance test lab validates new hydraulics and provides a new certified performance curve. Post-modification field testing can also be performed to provide data on field performance.
  • Continuous Monitoring: Using Hydro’s Centaur condition monitoring solution, equipment mechanical performance can be continuously monitored to provide better insight into equipment health into the future.

State of the Art Parts- Rerated Impeller

Hydro Parts Solutions recently manufactured three impellers for a rerate project being developed through Hydro’s Rocky Mountain service center in Denver, CO. Hydro Global Engineering determined the new hydraulic design for the rerated pump, which required modifications to the casing and new impellers.

 

The end user chose to have the new impellers manufactured out of CA6NM using investment casting, which provides a smoother surface finish to slightly increase the impeller efficiency. Hydro Parts Solutions drove the project from casting package design through final machining, with the impellers being cast and finish-machined within 6 weeks.

The new pump design was successfully tested at Hydro’s performance test lab, validating the new hydraulics. The custom performance will help the midstream end user achieve their desired system flow with maximum reliability and minimum energy usage.

Hydraulic Rerate Proven in Performance Test Lab

Custom Hydraulics for the Midstream Market

This summer, Hydro completed a hydraulic rerate project for a major US midstream pipeline. The project was completed through Hydro South, Hydro’s southeastern US service center in Alpharetta, Georgia. The project was completed with testing support from the Hydro Performance Test Lab, Hydro’s 5000 HP test facility located in Chicago, IL, with engineering direction from Hydro Global Engineering, based in Manchester, UK.

The pipeline originally used two booster pumps and the use of a Drag Reducing Agent (DRA) to achieve the desired flow rate. To increase the overall flow capacity of the line and remove the need for the DRA, the end user specified a pump to be added to the system downstream of the booster pumps.

The pump performance specifications were developed by system engineers and communicated to Hydro. The pump’s original design condition was modified to provide the necessary differential pressure required for the desired flow rate – for today and in the future. This will be achieved without the use of DRA or with little added to the system.

Hydro modified an existing pump casing provided by the pipeline and designed new impellers to meet the specific hydraulic performance requirements. Using computational fluid dynamics and advanced modeling, the new impellers were manufactured and installed by Hydro, then sent to Hydro’s test facility for hydraulic performance testing.

To provide an exact performance match, a larger impeller diameter size was selected for the first test and subsequently trimmed to meet performance within API 610 tolerances. Along with the hydraulic performance test, the mechanical integrity of the pump was measured with a vibration test, mechanical resonance test, and a bearing housing temperature stabilization test. All this information validates the quality of the rebuild and ensures a reliable machine.

The pipeline has a limited ‘budget’ of DRA concentration allowed pipeline wide. This concentration is measured in part per million (ppm). By adding the hydraulically rerated pump to the branch line, the DRA ppm budget can be allocated elsewhere in the pipeline. This will add efficiency and increase overall throughput.

Hydro is very fortunate to support critical industries like midstream pipelines in ensuring safe, reliable, and cost-effective pumps and rotating equipment.
