What Matters?
– It’s not...Just the pump,
– Nor the individual components
It is…– A properly designed integral system,
– And the operation of the same

Cost of operation savings through System Optimization
Application #1
Energy savings by means of “optimizing” the system to allow for proper operation.
The issue: An operational system that has optimal pump and system efficiency at 100% turbine load. However the system efficiency is compromised at normal operating levels of 70% load.
Project main Fuel Injection pumps feeding a 110Mw Simple Cycle Peaker

The Project;
HECO (Hawaiian Electric Co.) at the Campbell Industrial Park generating station on the island of Oahu.
The prime mover at this 110-MW simple cycle power plant is a U.S. manufactured combustion turbine.
The plant is designed to operate with B100 BioDiesel renewable fuel as its primary fuel supply, a unique feature in today’s marketplace.
Clean distillate fuel will also be used for system flush prior to shutdown and will be contained in the system during extended shutdown periods.

This type of operation is prevalent in nearly all combustion turbine installations built by US based manufactures.
Well, we now do know that this type of system can easily be “Optimized” by the addition of some Colfax “Smart System Controls”!

Consider that:
Without considering inflation and fuel costs in the future the energy saved in the operation of this fairly small combustion turbine will be nearly $2,500,000.00 over the 25 year life expectancy of the plant!
And this operational scheme will work on:

Application #2– Savings gained by considering other options in equipment selection in
lieu of the “Usual Type” of equipment previously utilized.– Then when using TCO comparisons in the design stage the overall
economic benefits will be clearly evident
Project: – Pipe line, Fuel Transfer, and Unloading systems
Solution:– The use of Positive Displacement pumps in lieu of the “Obvious
Choice” Centrifugal machines.

Cost of operation savings through System Optimization
Let’s look at a pipeline application where the operational conditions would normally call out for a multi-stage centrifugal pump….
This application is for a 4380GPM pipeline delivering a light crude oil…

31
In the Oil and Gas Industry there still remains a preference for the use of centrifugal pumps (even when horribly misapplied) because….
”We can always fix them in our shops”

Cost of operation savings through System Optimization
How about a pump that doesn’t break down?
Or, “Yes you can do an on-site repair quick and cheap”
But do you know how much it really costs to operate the equipment?
Despite the initial capital equipment costs and 5 years of parts and maintenance charges being nearly equal….
The total “Savings Gained” are:

Cost of operation savings through System Optimization
On average the cost of maintenance of the original design pumps is from $15,000.00 to $17,000.00 per year per turbine…
A Combined Cycle installation of 2 two Combustion Turbines and one Steam Turbine can cost around $40- $45 K per year
The Savings gained by doing it right are:
