THE PINCH-ANALYSIS AND OPTIMIZATION OF INDUSTRIAL FACILITIES

S. V. Zhulaev

Abstract

The existing methods of heat saving in the designed and operating industrial units, and also methods of designing of heat exchange networks are reviewed. The efficiency of the pinch method in heat saving, its convenience for designing of heat exchange systems, and its advantages in comparison with alternative methods are shown. The basic principles of pinch analysis, the sequence of performing of pinch analysis in an industrial unit, and difficulties pos- sible during carrying out of pinch analysis are described. Data concerning saving rate of pinch analysis in the leading world companies are presented. Modern upgrades to this method are reviewed.
