Valmet to supply BioTrac system to cellulosic plant in Romania

By Erin Voegele | October 23, 2018

Valmet has announced it will supply its BioTrac biomass pretreatment system to Clariant for use in its 500,000-ton-per-year (16.74 MMgy) sunliquid cellulosic ethanol plant in Podari, Romania. The facility is expected to begin operations in 2020.

The delivery includes a BioTract biomass pretreatment system with a capacity of more than 800 metric tons of dry biomass per day. It also includes all main parts for biomass dosing, the reactor, the feeding system to the reactor, and steam separation.

"We have successfully been using Valmet's pretreatment system in our pre-commercial sunliquid plant in Straubing for six years already,” said Markus Rarbach, head of business line biofuels and derivatives at Clariant. “During this time, we have closely worked with Valmet to verify and precisely optimize the pre-treatment process for sunliquid. We are confident that we have a reliable partner in Valmet for our sunliquid plant in Romania.”

"This is a very important milestone for Valmet, being the first commercial-sized BioTrac plant for cellulosic ethanol, said Mattias Erixon, manager sales, biomass conversion at Valmet. “We are very proud to receive this order from our long-term partner Clariant, who knows our system inside and out after six years of operation at their demo plant in Straubing."

Clariant first announced plans to construct the sunliquid plant in Romania in October 2017, noting that the planned facility is expected to process approximately 250,000 tons of wheat straw and other cereal straw annually. 

Construction on the project commenced on the project nearly one year later on Sept. 12, 2018. The facility represents the first commercial deployment of its sunliquid technology.
