Plants install System 800xA as they aim at optimizing energy consumption and use of renewable forest resources to "green" the industry while increasing production.
ABB has won two orders to provide automation systems and related services for Chinese pulp and paper producers. Both are aimed at improving resource use and energy consumption in an effort to cut costs and help "green" an industry with a spotty history.
The first project provides Chemical and Pulping Ltd. (CPL) and its Rizhao Huatai mill with technology that supports production of pulp made out of fast growing wood. ABB will be supplying System 800xA as the platform for CPL’s displacement digester system (DDS), designed to help the mill’s fast growing wood production achieve a "4-high" – high optimization rate of energy and chemicals, high pulp conversion rate, and high production efficiency. ABB will also supply accompanying automation equipment, systems, and engineering services.
"The strong union of ABB and CPL is advancing DDS technology throughout the world by upgrading production efficiency, raising the pulp yielding rate and reducing use of steam and chemicals," said Lin Shuming, head of ABB pulp & paper, North Asia.
CPL is a U.S. company that provides technology and equipment for the pulp, paper, and chemical industry. The company’s DDS solution employs sophisticated batch digester technology, which saves energy and chemicals and yields high quality pulp.
The second project is a contract to update Sun Paper’s Shandong mill with System 800xA in a larger mill capacity expansion. ABB’s System 800xA will be installed to control and improve the output the mill’s new fine paper machine PM23, supplied by Metso. Once operational, the new line is expected to increase the mill’s capacity by 300,000 tons of uncoated fine paper per year.
ABB says it has worked with Sun Paper on a number of successful projects at the Shandong mill over the years. For this project the scope of supply includes the System 800xA to control, monitor, and optimize operation of the new paper machine, while integrating other systems and devices in the plant. The system will include 11 operator workstations and over 5,000 I/O points. ABB will also provide related engineering and installation services.
