Century Pulp and Paper to install new evaporation line with a capacity of 275 tons of evaporated water per hour

Lalkuan | 17 February 2020 | The Pulp and Paper Times:

Century Pulp and Paper (CPP) has given an order to Valmet to supply an evaporation line with a design capacity of 275 tons of evaporated water per hour, producing heavy liquor of 75% dry solids. The plant is designed to handle black liquor based on 60% bagasse and 40% wood. The delivery covers main evaporator effects, a surface condenser, an integrated foul condensate treatment plant, flash tanks, main supporting structures, and a vacuum system.

“Century has always been in the forefront of implementing efficient technologies across the entire value chain and the Valmet Evaporator is another step in this direction,” says J.P. Narain, CEO, Century Pulp and Paper.

The new evaporation line will meet the future needs of the mill's ongoing pulp production capacity expansion, together with the existing evaporation line. This investment will also improve the overall steam economy of the mill.

The order was included in Valmet’s orders received of the fourth quarter of 2019. The value of an order of this size and delivery scope is typically below EUR 10 million. The new evaporation line is planned to start up during the latter part of 2020.

“In an Integrated pulp and paper mill, the recovery line is a vital part in securing the mill’s operations. In view of this, we decided to go with the latest and most advanced evaporation technology. We evaluated different alternatives and decided to choose Valmet. Our new plant should be commissioned by December 2020,” says P.K. Mittal, Head of Process, Century Pulp and Paper.

 â€œThis is Valmet’s first evaporation plant installation in India. We were able to offer clear technical advantages through our customized and detailed design done by our technical team, and the solution was appreciated by the customer. The project execution has started in a very smooth way and both the customer and Valmet’s teams work as one team for the successful execution of the project. We are looking forward to creating a good reference with leading technology in India,” says Varun Jain, Director, India Region, Valmet.
