Valmet to deliver biomass pretreatment system to Clariant cellulosic ethanol plant in Romania

By -


Type of post: NEWS IN BRIEF.

Valmet has agreed with Clariant on the delivery of a biomass pretreatment system for its Sunliquid cellulosic ethanol plant in Romania. The package includes a BioTrac system with a capacity of over 800 tons of dry biomass per day, as well as all main parts for biomass dosing, the reactor, the feeding system to the reactor and steam separation. The pretreatment phase is an essential step in cellulosic ethanol production whose goal is to make the cellulose accessible for further processing.

Clariant has successfully been using Valmet's pretreatment system in its pre-commercial Sunliquid plant in Straubing for six years. During this time, they have closely worked with Valmet to verify and precisely optimize the pretreatment for the Sunliquid process. This is a very important milestone for Valmet, as it is the first commercial-sized BioTrac system for cellulosic ethanol.

Publication date: 14/12/2015 Last update: 24/05/2017 Description 1,2,3,4 D-Glucaric acid, also called saccharic acid, is a chemical compound with formula C 6 H 10 O 8 and member of a large family of molecules known as oxidized sugars. It is a naturally occurring aldaric acid, typically found in small amounts in a variety of fruits and vegetables. It is a highly functionalized compound with four chiral carbons and a plethora of reaction pathways. Its commercial potential was unveiled in the report “Top Value Added Chemicals from Biomass” from the Department of Energy of USA which described its use as a building block for a number of polymers, including new nylons and hyperbranched polyesters. Process technologies 1,3,4,5,6,7,8 The synthetic preparation of D-glucaric acid dates back to a report of Sohst and Tollens (1888) who carried out the nitric acid oxidation of D-glucose to D-glucaric acid. Current methods for its production are based on this process and in...

Proyecto PULP2VALUE – Un modelo de biorrefinería para la pulpa de la remolacha azucarera

By -

La UE lidera la producción de remolacha azucarera con cerca del 50% del total. La mayor parte de ella se procesa para obtener azúcar líquido o cristalizado que posteriormente se utiliza en aplicaciones alimentarias. Sólo el 2% del total de la producción de azúcar se usa en aplicaciones no relacionadas con la alimentación (por ejemplo, la producción de bioetanol en biorrefinerías convencionales de azúcar). El sector azucarero necesita desarrollar nuevos mercados para crecer. Una de las oportunidades pasa por impulsar el uso del azúcar como base para fermentación lo que permitirá llevar a cabo procesos simplificados con menos demanda energética y emplear todo el contenido de azúcar en la fabricación de productos de alto valor añadido. Un buen ejemplo es el proyecto industrial para una planta de biopolímeros basados en PHAs que Cristal Union (líder de la producción de remolacha azucarera en Francia) y Bio-on construirán en Francia (ver nota de prensa ). Pero, esta no es la ún...
