AFT Presents at Dupont Energy 2005
Dupont Energy 2005 held a 3-day conference concentrating on the subject of energy efficiency April 26-28 in St. Louis. Representatives from several Dupont facilities attended to learn about technologies and methods to improve energy efficiency in their plants. A Vendor / Valued Supplier show was held in parallel April 27.
Along with Dupont’s Judy Hodgson and Rob Mulrooney, AFT’s Tom Glassen co-presented “Using AFT Fathom for Energy Efficient Pump Design”. The presentation included a demonstration of methods to evaluate and apply variable speed drives to pumping systems along with case histories of various Dupont applications.
The evaluation demonstration used particulars from one of Dupont’s tempered water systems and showed how, using AFT Fathom, energy consumption could be reduced by 72% from a combination of pump impeller trimming and application of a variable speed drive. In addition, the AFT Fathom evaluation identified significant non-energy benefits in the form of reduced pump maintenance cost and improved pump reliability by keeping operation much closer to the best efficiency point.
Case histories presented by Judy and Rob illustrated solving operational problems and designing a system expansion using AFT Fathom. These case histories provided an excellent of how a properly designed hydraulic system also yields efficiency improvements. In the case of the system expansion, the original design called for three, 40 HP pumps. After checking the design using AFT Fathom it was determined three, 15 HP pumps would meet the requirements. A more than 60% reduction in installed pump power.
Customer’s Speak Out
While AFT regularly receives favorable feedback on our software and support, we never tire of receiving comments like this one from Walter Hull of Black & Veatch;
“Thank you for the quick response, it helped me considerably. Your software has been very helpful, and with it we are redefining the way we analyze flow piping. We look forward to future releases and the continued development, as no doubt each one will be more robust and with more functionality.”
Tip
Reviewing Output in the Workspace Window
You can see output in the Workspace window by pressing the CTL key while right-clicking a pipe or junction (left-clicking for a left handed mouse). Output displayed is that currently selected within Output Control so, if you don’t see the information you’re looking for, simply open Output Control from the Analysis menu and add the desired parameter to the ‘Show Output’ list.
