    • Consideration of Fouling During the Design of Crude Oil Pre-Heat Trains 
      Polley, G. T.; Pugh, S. J.; Wilson, D. I. (Energy Systems Laboratory (http://esl.tamu.edu), 2001-05)
      Over the last five years significant progress has been made in the modelling of fouling in refinery pre-heat exchangers. In this paper we consider how such information can be exploited in the design of individual units ...
    • Dealing with Uncertainties During Heat Exchanger Design 
      Polley, G. T.; Pugh, S. J. (Energy Systems Laboratory (http://esl.tamu.edu), 2001-05)
      Over the last thirty years much progress has been made in heat exchanger design methodology. Even so, the design engineer still has to deal with a great deal of uncertainty. Whilst the methods used to predict heat transfer ...
    • Design of Crude Oil Pre-Heat Trains 
      Polley, G. T.; Yeap, B. L.; Wilson, D. I.; Panjeh Shahi, M. H. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      Pre-heat trains differ from most other heat recovery networks in a number of important ways. Combination of factors gives rise to the need for a design procedure specific to pre-heat trains. Outlining these factors, we ...
    • Emerging Heat Exchanger Technologies for the Mitigation of Fouling in Crude Oil Pre-Heat Trains 
      Polley, G. T.; Pugh, S. J.; King, D. C. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      Over the last three years ESDU have been working with engineers from oil companies and the companies that serve them in order to produce a guide describing the current state of knowledge on fouling in pre-heat trains and ...
    • Heat Exchanger Technologies for Distillation Columns 
      Polley, G. T. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      In this paper we look at the challenges that improvements in energy efficiency of distillation systems presents the heat exchanger designer. We examine each type of exchanger in turn. Heat exchanger size is minimized if ...
    • Identification of R&D Needs Relating to the Mitigation of Fouling in Crude Oil Pre-Heat Trains 
      Polley, G. T.; Pugh, S. J. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      Worrell & Price (at a paper presented at the Industrial Energy Technology Conference organised by Texas A&M University and held in Houston in May 2001) examined the potential of over 50 emerging energy efficient technologies ...
    • Low Energy Distillation Schemes 
      Polley, G. T. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      In this paper we look at various options available for the reduction of energy consumption in distillation systems. For binary systems, we look at how heat pumps can be used. With multi-component systems, process integration ...
    • Models for the Prediction of Fouling in Crude Oil Pre-Heat Trains 
      Yeap, B. L.; Wilson, D. I.; Polley, G. T. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      Fouling has two significant effects upon pre-heat train performance. Firstly, any of layer of foulant on the heat transfer surface presents a resistance to heat transfer. This thermal resistance increases as the layer ...
    • Pinch Technology Without Tears 
      Polley, G. T. (Energy Systems Laboratory (http://esl.tamu.edu), 2001-05)
      In the mid-eighties engineers were rushing to hear about Pinch Technology. Conference rooms were full. Training courses were over-subscribed. Here was the technology that was going to provide the standard design tool for ...
    • Process Considerations in Surface Condenser Design 
      Polley, G. T.; Terranova, A.; Capel, A. C. P. (Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)
      Condenser Design engineers and process engineers need to work closely together if efficient designs are to be made. This paper examines the importance of such interactions and outlines how it can be achieved.
    • Revamping Pre-Heat Trains for Energy Saving 
      Yeap, B. L.; Wilson, I.; Pretty, B.; Polley, G. T. (Energy Systems Laboratory (http://esl.tamu.edu), 2002-04)
      In this paper we look at the principles underlying the revamping of pre-heat trains to save energy through increased heat recovery. For brevity, we do not consider throughput changes. Only pre-heat train performance is ...
