Upgrading control for better polymer performance

Polymer producer to add APC to polyethylene lines to drive process output and quality.


Korean-based polymer manufacturer Daelim Industrial will be implementing Pavilion8 model-predictive control technology on multiple polyethylene production units to help increase output and improve quality.

Pavilion’s advanced process control platform will be installed on three production lines at Daelim’s facility in Yeosu, Korea. The plastic producer will implement the Pavilion Polymer Solution on two high-density polyethylene (HDPE) lines and one linear low/high density polyethylene (LHDPE) line to help drive operational performance while maintaining regulatory compliance.

“Technical innovation and continuous improvement are essential to the future success of our company,” says D.H. Seong, polyethylene production team manager for Daelim. “We continue to gain a competitive edge in the polymer industry by relying on proven technologies like the Pavilion Polymer Solution, which helps us maintain and increase our profitability.”

Pavilion says that polymer processes differ from most large-scale petrochemical processes due to the high volume and variety of products produced. As a result, operations focus on maintaining product quality during on-grade conditions and transitioning from one grade to the next in an efficient manner. Since polymer plants operate in a nonlinear fashion over a wide range of conditions, most traditional linear control solutions fail to provide the level of control needed for these producers.

The Pavilion Polymer Solution is based on the Pavilion8 integrated software suite to provide modeling, prediction, control, and optimization capabilities in one unified platform. This is intended to provide companies with real-time and predicted measurements for process variables to help reduce dependency on lab samples while helping to improve production efficiency and product quality.

“In today’s unpredictable market landscape, producers increasingly are recognizing the value of advanced process control and investing in its ability to improve production operations,” says Greg Jackson, president of Pavilion Technologies.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
