    • CHP Modeling as a Tool for Electric Power Utilities to Understand Major Industrial Customers 
      Kumana, J. D.; Alanis, F. J.; Swad, T.; Shah, J. V. (Energy Systems Laboratory (http://esl.tamu.edu), 1997-04)
      In the face of pending deregulation, many electric utilities are struggling to retain major industrial customers. The strategies for retaining customers, especially those with cogeneration options, include: • Superior ...
    • Demand Side Dispatching, Part 1: A Novel Approach for Industrial Load Shaping Applications 
      Kumana, J. D.; Nath, R. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
      In order to develop effective Demand Side Management (DSM) programs, it is important to properly understand the cogeneration capabilities of large industrial customers. Projecting historical trends may be simple and ...
    • Electrical Power Savings in Pump and Compressor Networks via Load Management 
      Kumana, J. D.; Aseeri, A. S. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2005)
      Large industrial plants commonly use multiple parallel units in pump and compressor networks for improved reliability. Sometimes, installed equipment capacity can far exceed actual requirements. This excess capacity can ...
    • Energy Management Program of an Integrated National Oil Company in the Middle-East 
      Kumana, J. D.; Aseeri, A. S. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2007)
      Saudi Aramco is the largest oil producer/exporter in the world, with a maximum sustained production capacity of over 10 MM bpd of crude oil and 8,000 MM scfd of natural gas. The Company operates approximately 32 large ...
    • Marginal Cost of Steam and Power from Cogeneration Systems Using a Rational Value-Allocation Procedure 
      Kumana, J. D.; Al-Gwaiz, M. M. (Texas A&M University (http://www.tamu.edu); Energy Systems Laboratory (http://esl.tamu.edu), 2004)
      The problem of pricing steam and power from cogeneration systems has confounded engineers, economists, and accountants for a very long time. Normal industry practice is to fix the cost of one (usually power) at its ...
    • Meaningful Energy Efficiency Performance Metrics for the Process Industries 
      Kumana, J. D.; Sidhwa, N. R. (Energy Systems Laboratory (http://esl.tamu.edu), 2009-05)
      An effective energy performance benchmarking should include a consideration of production rate, product specifications, feedstock mix, and process type, in addition to thermodynamics and economics. Unfortunately, there ...
    • NOx Dispatching in Plant Utility Systems Using Existing Tools 
      Nath, R.; Kumana, J. D. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-04)
      Localized NOx reduction during Ozone Alerts is a problem of increasing importance to process industries in and around heavily industrialized areas. New regulations by local and federal agencies are being developed, and ...
    • Optimizing the Utility System of a Tissue Paper Mill Using Pinch Technology 
      Kumana, J. D.; Sung, R. D. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1989-09)
      A tissue paper mill in southern California had existing utility demands of 7.1 MW for the tissue mill (13 MW for the whole site), and 55 MM Btu/hr of fuel gas for the steam boiler. Total utility costs were $12 MM per year. ...
    • Use Spread-Sheet Based CHP Models to Identify and Evaluate Energy Cost Reduction Opportunities in Industrial Plants 
      Kumana, J. D. (Energy Systems Laboratory (http://esl.tamu.edu), 2001-05)
      CHP (for Combined Heat and Power) is fast becoming the internationally accepted terminology for describing the energy utilities generation and distribution systems in industrial plants. The term is all inclusive -boilers, ...
