YOUR CHALLENGE:

VARIATION IN THE PAPERMAKING
PROCESS CAUSES ISSUES
Of all the variables in your process that impact drainage stability, entrained air is the invisible villain with the greatest ability to disrupt everything. When it goes up, drainage slows, defoamer gets overused, and steam needs increase, leading to potential breaks, pinholes, moisture variations, and other defects.

VARIATION IN THE PAPERMAKING
PROCESS CAUSES ISSUES


Of all the variables in your process that impact drainage stability, entrained air is the invisible villain with the greatest ability to disrupt everything. When it goes up, drainage slows, defoamer gets overused, and steam needs increase, leading to potential breaks, pinholes, moisture variations, and other defects.

Did you know…

Typical levels of entrained air in various papermaking furnishes are in
the range from 0-8%?2

So what?

That’s an enormous liability and source for concern. By comparison, your typical 12 oz. soda drink contains around 4% air content by volume once the pressure is released.

 

With rising consumer demand for paper products with higher specifications (e.g., lighter-weight, stronger packaging), your team needs to operate with absolute precision and discipline. But as variables fluctuate, some of your operators might switch into manual control. This increases your process variability and leads to higher costs in chemicals, greater energy usage, and more man hours to balance it all.

THE SOLUTION:

REMOVE THE HIDDEN VARIABLE

Your process will always be subject to variations, but it’s difficult to solve issues when their root causes are obscured by so much noise. When you partner with Buckman, you’ll make entrained air measurements accurately and automatically, using this data to implement closed-loop control—thereby keeping entrained air under control.

Here’s what you need to do to make it happen:

AUTOMATICALLY UPGRADE YOUR CONTROL ALGORITHMS

Thanks to Buckman’s Ackumen™ ECHOWISE® Pro sonar-based technology, you can confidently measure entrained air without drift, so you can more clearly troubleshoot and fix variations that aren’t caused by air.

And because ECHOWISE Pro reads air every 1.5 seconds and feeds that data directly to your DCS, you’ll be able to create centerlines to compare with other process values—and bring your control directly into phase with your real-time operations.

 

 

 

MAINTAIN YOUR CENTERLINE REGARDLESS OF VARIATIONS

When your team sees how consistently the system runs using our Ackumen™ ECHOWISE® Pro auto-control capabilities, you’ll greatly reduce the temptation to run in manual—and many of the variables that have stalled performance in the past—improving your drainage capability, efficiency, and overall paper quality. For example, you might want to hit a 1% entrained air mark for one grade and 2% for another. By taking advantage of closed-loop control, you’ll not only be more precise about hitting specific targets across your runs; you’ll hold to them, so you can actually hit your output goals without human error.
