Valmet to convert Estonian Cell BCMTP plant

The order will be completed in two stages: first, Valmet will supply a conversion of the existing bleached chemi-thermomechanical pulp plant, which will increase production and reduce steam, fresh water and chemical consumption. Then, Valmet will deliver a slab press and conveyor systems with connecting control system. The new machinery will boost production capacity and make the line more cost-efficient. The second stage will increase the annual production volume.

Valmet’s delivery is part of Estonian Cell’s EUR 20 million growth investment program that will enable the company to achieve an annual production capacity of 185,000 tons and improve the plant’s efficiency. In 2017, the production capacity of Estonian Cell was 171,708 tons of aspen pulp and all production was exported.

The BCTMP plant conversion includes a mechanical steam separator, a new washing stage by a screw press with medium consistency pump and a new final washing stage before the flash dryer with heavy duty TwinRoll presses. Reconfiguration and reprogramming of the existing bleaching system with detailed automation engineering is also included. The new slab press is replacing the original slab press, which was a prototype that did not meet stability expectations. Mechanical installation of the slab press is included. Commissioning and start-up supervision are included for both stages.

A project of this size and scope is typically valued at EUR 5-10 million. The start-up is planned for the second quarter of 2019.

“We are ready to start with the first stage of the investment program which focuses on liquidating the bottlenecks of the production and wastewater treatment and improving efficiency,” said Lauri Raid, mill manager at Estonian Cell. “In the second stage, we have chosen to invest in another slab press from Valmet to increase our production capacity. The good experience from the earlier installed slab press, which increased availability and stabilized production, makes us confident that this investment will make us reach our set production target.”
