For Energy Conservation in Existing Plants - Start With a Good Process Survey
MetadataShow full item record
As a result of the drastic increase in the cost of process plant utilities, many operating companies are actively pursuing programs to effect energy conservation in their existing plants. Some have taken action to reduce the outright waste of energy by improving maintenance, operating procedures and energy management. However, significant additional savings can be realized by modifying those process schemes that are inefficient from an energy standpoint. To identify those schemes, a good overall process survey is required. This survey will result in the identification of areas of energy loss. A good energy survey will be defined and the need for it will be discussed. The screening procedure to select the most attractive project for further process design will be addressed. The importance of emphasizing the overall picture, during all phases of the process survey, will be stressed. In short, this paper will address the what, why, and how of a 'Good Process Survey'.
