Valmet has received an order for the new magnesium oxide (MgO) no 3 brown stock washing and screening line for the Sappi Saiccor mill in South Africa.
The delivery is part of the Vulindlela Project which targets to reduce the Saiccor mill's air emissions and effluents, and to increase its total production from 783,000 ADt/a to 890,000 ADt/a. The capacity of the new MgO no 3 brown stock and screening line will be 720 ADt/d.
The order is included in Valmet's third quarter of 2018 orders received. The value of the order will not be disclosed. An order with this scope of supply is usually valued in the range of EUR 5-10 million. The new line is scheduled to start up in June 2020.
The agreement is a continuation to the long-term successful cooperation of Sappi and Valmet. Valmet has earlier delivered key processes to other Sappi mills in South Africa.
"Valmet and its TwinRoll press technology was selected due to the ease of access for descaling and maintenance, high washing efficiency, low water consumption and low fugitive emissions to atmosphere," says Wayne Weston, Project Director at Sappi Saiccor projects.
"Valmet's large reference base for fiberline key equipment, such as the TwinRoll presses for Sulphite pulp/dissolving pulp, gives confidence to our customers that we can handle their special processes. We are happy to be a part of the Vulindlela Project and it is an important breakthrough for Valmet to utilize the TwinRoll presses in the Saiccor mill," says Eva Engelfeldt, Sales Manager, Fiber Processing Business Unit, Valmet.
