We can introduce you to Pinch Analysis with our basic 3-day introductory course given on your site for a maximum of 10 participants.

The objective of this course is to introduce the participants to the major concepts of Pinch Analysis and to learn how to design solutions that will maximize process energy recovery in real life situations.

We know a case where this course has led a plant technical services to identify and implement projects that have saved fossil fuels for about 1.5 millions $CAN a year within a few months payback period. Contact us for more information or to organize a session.

You can also consult the following reference book:

Energy cost reduction in the pulp and paper industry - A monograph
Published by Paprican (PAPTAC), November 1999

in which Pragmathic's associate Mr. NoŽl is a joint author of the chapters on process simulation and Pinch Analysis.
