It all starts with a detailed Vacuum System Survey and in-depth analysis.
A vacuum system survey should precede any former or press section upgrade or rebuild. The entire system is studied over a 2–3 day period, beginning with an informal meeting to discuss your goals and percieved vacuum and dewatering problems. Analysis is provided and reviewed in an exit meeting. A full written report follows the on-site study.
Usually, a specific problem initiates the vacuum survey (e.g., low vacuum levels, poor machine efficiency, vacuum system motor overloads or vacuum control issues). During the study the entire vacuum system is analyzed and root causes identified. Changes to resolve problems can often be made immediately. It is common to uncover additional opportunities leading to system and dewatering optimization which were not anticipated prior to performing the survey.
Vacuum System Energy Reduction
Energy saving plays an increasingly important role and is often a primary motivation for conducting vacuum audits. Energy reduction of 10–15% of vacuum system operating power is common and can be as high as 25%. System optimization and better utilization of installed vacuum is always the key benefit of energy reduction studies. Frequently, these savings are available with little or no capital cost.
Energy Savings Example
Following the study of 14 paper, board and pulp machines for a Canadian manufacturer, 3.6 MW of potential energy savings was identified. The combined vacuum systems had 50,000 installed horsepower. The cost associated with tapping almost half of this energy savings windfall was negligible. Even with low hydroelectric rates, almost $500,000 can be saved annually.
