Realistic Industrial Scale Energy Optimization: Part II - Analytic Techniques

Abstract

With long term predictions of increased cost and reduced availability of energy, plant managers are reviewing their options to optimize energy utilization to reduce operating costs. This paper deals with the organization and execution of an energy conservation program which will maximize savings through the most efficient utilization of energy that will meet the preponderance of constraints which are found in process industry. The first part of the paper described a realistic and practical approach to organizing and executing an energy conservation program. The energy audit was particularly stressed. This part discusses the analytic techniques which are employed during the engineering phase of the program. Included are: targeting methods, process optimization, heat exchange optimization, cost estimation and project selection by linear programming.
