Valmet develops service agreement for dryer section performance for tissue machines
August 29, 2022 By P&PC Staff
Valmet has developed a service agreement as part of its services offering for tissue producers. The agreement aims at improving the performance and safety of the Yankee cylinder, hood and air system.
The dryer section consumes roughly 70 percent of all the energy used in the tissue-making process. It is the major CO2 producer in the process. Valmet states that a timely and correct maintenance plan, as well as control of process parameters, is essential for safety, end product quality and energy efficiency.
“By keeping the process at an optimal level, the risk of unplanned shutdowns due to Yankee failure is reduced by 99 percent, production efficiency increased by one to two percent, drying energy consumption and related CO2 emissions reduced by three to 10 percent,” says Raffaele Malutta, agreement manager for tissue service at Valmet.
Valmet’s new agreement offers a systematic approach to improve the performance of the dryer section. An optimal length for the agreement is five years. Every agreement starts with a complete condition check and energy study. The rest can be tailored to the customer’s needs by adding the right combination of services, such as Valmet Industrial Internet solutions, remote support through Valmet Performance Center, improvement plans and maintenance guidance.
Valmet’s typical service agreements range from corporate-level frame agreements to mill-level partnership agreements.
