Valmet (Finland) will supply an automation system update and expansion for Gasum's project at the Metsä Tissue Mänttä mill in Finland. As part of the project, the mill will replace liquefied petroleum gas (LPG) with Gasum's low-emission liquefied natural gas (LNG) in the burners of the drying processes on its tissue machines. The order is included in Valmet's fourth quarter 2018 orders received. The system renewal will be delivered in June 2019.

Valmet's automation system will be used to control the burners of the drying processes and manage a gas terminal that will be connected to Valmet's data collection application. The delivery will standardize and optimize the tissue drying process and quality management.

"Valmet's flexible approach and familiarization with Metsä Tissue enabled us to offer a turnkey delivery to the customer," said Tommy Mattila, Sales and Marketing Director, Gasum.

"Valmet will enhance the Metsä Tissue mill's fuel switch to LNG, which is a safe form of energy with low emissions. At the same time, both Gasum and Metsä Tissue gain access to the latest software updates," remarked Juhani Tuomaala, sales manager, Automation, Valmet.

Valmet will update and expand the Valmet DNA automation system on the TM's to modernize burner controls and the drying process management. Valmet's delivery includes automation controls with DNA Modbus links to the burner and gas terminal PLCs as well as necessary DNA I/O expansions on the tissue machine automation systems. The delivery also includes DNA software updates and expansions in the process air systems and drying power control systems of the tissue machines.

Gasum will carry out the modifications needed for the fuel switch as well as all equipment installation.
