4 What is ESDU? ESDU = Engineering Sciences Data Unit “Where research meet Design” Database of Validated Designs for the Engineer: –Aerospace –Process Control –Petrochemical –Wind Engineering –Nuclear Power –Structural Engineering Produced by international experts from the Industry and Universities.
5 Problem... Where do we nail the wings on this thing? We want it to fly level. How do we find out?
6 Solution - Use ESDU! Find the C/L for the wing and the C/B for the body. Then line ‘em up! Here’s how...
7 Example of ESDU application Fouling in Heat Exchanger
8 What is the biggest cause of inefficiency in heat exchanger? Heat exchanger fouling Dirt deposits build up on clean tubes, and efficiency plummets!!
9 Where are heat exchanger fouling problems found? All processing industries, but especially in the Oil Industry Most important fouling type - Crude Oil Fouling in Refineries
13 The crude oil gets a final “blast” in the furnace prior to distillation $$$ $$ $ CO 2
14 Economic and environmental significance of fouling in crude distillation units: $1300 M p.a. in US alone (Argonne National Labs, 1995) Scaling up, $4500 M p.a worldwide!
15 Total Annualised Cost: 200,000 $/ann Conventional, oversized design, heavy fouling
16 Total Annualised Cost: 103,000 $/ann New ESDU clean design, no fouling
17 ESDU’s EXPRESS program! “Financial losses were tremendous and were estimated to be around 1.5M$ over three months after start-up.” – Description of fouling problem in TOTAL refinery, since solved by TOTAL engineers using ESDU’s EXPRESS program. (from TOTAL paper presented in “Heat Exchanger Fouling and Cleaning – Fundamentals and Applications" conference, Santa Fe, 2003.)
