Finland-headed forest industry and energy technology major Valmet Oyj has announced that it has been selected to deliver the key process technology for a new cooking, fiberline and recausticising plant, as well as a new lime kiln, at Naini Papers' mill in India. The new plant is expected to produce approximately 100 000 tonnes bleached hardwood pulp per year, and start-up is scheduled by the end of the first quarter in 2020.
According to a statement, the fiberline order was made during the fourth quarter of 2018 whereas the lime kiln order was made this year. The value of the orders has not been disclosed although Valmet says that a typical value of these kinds of projects is around EUR 20-25 million.
Founded in 1995, Naini Papers Ltd is one of the few premier paper manufacturing facilities in India. Naini offers high-quality writing and printing papers with improved physical and optical properties.
Our aim with this project is to have a modern and environmentally friendly fiberline that will give us both low effluents and low operating costs. Valmet’s fiberline and lime kiln meet these expectations, said Pawan Agarwal, Managing Director at Naini Papers.
Scope of supply
The batch cooking and fiberline delivery include a digester plant consisting of three conical bottom digesters, and a fiberline comprised of seven Valmet TwinRoll presses, screen room, MC pumps, mixers, and tower scrapers, as well as the basic engineering and site services. The recausticizing delivery also includes one OptiDisc WL.
The new long wet lime kiln has a design capacity of 200 tonnes per day, with a chain system for drying the lime mud inside the kiln. The kiln will be supplied with a burner system designed for either firing producer gas in combination with furnace oil or alternatively firing 100 percent furnace oil. The producer gas is a low-temperature, low-grade gas produced in a coal gasifier.
The Naini plant is already equipped with a modern wet washing system, continuous digester, oxygen de-lignification plant, and multi-stage bleaching.
According to NK Jain, Valmet’s Sales Director, Asia-Pacific Pulp & Energy, there were several important factors that led to Naini selecting Valmet.
In this project, we are able to utilize our strong presence in India, our local supply and our state-of-the-art TwinRoll press technology. These advantages helped us earn the customer’s trust as a reliable and experienced leader in pulping processes, Jain said.
