Page 1 © Copyright Cal Gavin Enhancing performance of tubular heat exchangers using hiTRAN Systems INTHEAT Friday 8 th July 2011
Page 2 © Copyright Cal Gavin Providing solutions to: Increase plant capacity Reduce energy costs Increased equipment performance Reduce production costs Provide operational flexibility Increase plant profit !
Page 3 © Copyright Cal Gavin Identify equipment and control system limitationsReview technology options to overcome limitationsIncorporate selected retrofit technologiesSimulate performance of new production plan Implement low cost retrofit solutions
Page 4 © Copyright Cal Gavin hiTRAN tube-side heat transfer enhancement system – increases heat transfer up to 8 times reducing fouling by increasing fluid sheer Direction of Flow
Page 5 © Copyright Cal Gavin How hiTRAN Wire Matrix Elements work hiTRAN Matrix Elements remove the boundary layer and mix it with the bulk flow. Fluid from the centre is displaced in the direction of the wall Residence time of the fluid at the wall is considerably reduced. Improved heat and mass transfer and reduced fouling Red dye: A) Laminar flow B) turbulent flow Blue dye: hiTRAN Matrix Element

Page 7 © Copyright Cal Gavin Case study LUKOIL Refinery, Volgograd Feed Effluent Exchanger Problem Plant capacity limited by low heat exchanger performance (mal-distribution) Recovered heat was 19 MW but …… 23.1 MW needed to meet target temperature Fired Heater performance much too low! 4.1 MW not available from Fired Heater High on-going energy cost if upgraded Plant expansion now requires 28MW
Page 8 © Copyright Cal Gavin Case study Lukoil - refinery Volgograd Optimised Engineering Solution Study identified hiTRAN System would solve the problem Reduce maldistribution on tubeside - balance flow Increase tubeside heat transfer hiTRAN System retrofitted in just 2 weeks
Page 9 © Copyright Cal Gavin Case study Benefits to Lukoil hiTRAN System increased performance from 27.8MW to 32.4MW 4.6 MW energy load saving without requiring new fired heater Fuel saving of over US$500K per year (at full flow rate) Enables higher plant throughput Increased plant profit!
