The biorefinery will be the first industrial-scale facility of its type ever built. It will apply novel process innovations to sustainably convert wood into bio-based mono-ethylene glycol (MEG), mono-propylene glycol (MPG) as well as renewable functional fillers (RFF). The plant is scheduled for start-up in late 2022. When fully operational, it will have a total annual capacity of 220,000 tons.

Siemens Energy’s scope of supply for the project includes:
- Electrification: mill-wide medium- and low-voltage power distribution system and drive system (motor control center, variable speed drives, motors);
- Automation: Distributed control system (DCS) for multiple process areas and remote I/O cubicles (total of 9,000 process objects), including safety and ATEX functions for explosive atmospheres; 
- Digitalization: Complete digital twin for the entire plant, covering the mill’s whole life cycle – from integrated engineering to integrated operation.

Publication date: 16/10/2015. Last update: 20/12/2016. Introduction The blog will open soon a new section focused on summarizing the information available about the commercial and pilot plants of the most promising Biobased Chemical Building Blocks (BCBB). The section will contain links to monographic posts updated in a regular basis. I have chosen bio-succinic acid to start the series because some companies have achieved important milestones related to its large-scale commercialization. Clearly, it is one of the DoE´s top 12 BCBB that it is fulfilling the previous generated expectations. Description 1,2,3 Succinic acid (butanedioic acid), is a diprotic, dicarboxylic acid with chemical formula C 4 H 6 O 4 . It is a water-soluble, colorless crystal with an acid taste. The name derives from Latin “succinum”, meaning amber, from which the acid was originally obtained by pulverising and distilling it using a sand bath. It is produced naturally as a product of cellul...

Alcohol-To-Fuel

Type of post: OVERVIEW. Introduction Bioethanol produced from fermentation of sugar based crops is the major product of the biofuels industry [1]. But, ethanol is not a “drop-in” solution and requires substantial changes in refining or distribution infrastructure. The properties of this alcohol (an oxygenated single molecule) are largely different than those of gasoline, diesel and jet fuel blendstocks (mixtures of hydrocarbons), leading to problems in blends. Ethanol can cause corrosion problems in transport pipelines that were designed to work only with gasoline. In the specific case of the aviation fuel, there are stricter quality requirements than fuels used in road transport. Ethanol shows low compatibility as a blendstock for aviation fuel because of its high volatility and water absorption and low flash point and energy density. Butanol is not as incompatible as ethanol, however, it still poses unacceptable safety risks due to its low flash point and high volatilit...

Versión en Español Type of post: NEWS IN BRIEF. Mitsui Chemicals , Neste and Toyota Tsusho have joined forces to enable Japan’s first industrial-scale production of renewable plastics and chemicals from 100% biobased hydrocarbons. Press release: “ Neste, Mitsui Chemicals and Toyota Tsusho collaborate to start Japan'sfirst production of renewable plastics from 100% bio-based hydrocarbons ”, 20/05/2021. Related post: “ Neste RE – Neste launches a 100% renewable and recycled raw material for plastics and chemicals production ”, 01/12/2020. In this collaboration, Mitsui Chemicals will use Neste RE, 100% biobased hydrocarbons produced by Neste, to replace a part of the fossil feedstock in the production of a variety of plastics and chemicals at its crackers within Osaka Works during 2021. In doing so, Mitsui Chemicals will become Japan’s first company to use biobased feedstock in its crackers. The introduction of Neste-produced biobased hydrocarbons as feedstock will allow Mitsui ...

Key of the process: Treatment with hydrogen. In the HVO production process, hydrogen is used to remove the oxygen from the triglycerides producing a mix of linear paraffins, CO 2 and water. Then, the product of the first stage is isomerized, always in presence of hydrogen, in order to branch the linear chains for improving the cold flow properties of the final products. Thus, HVO are mixtures of paraffinic hydrocarbons, free of sulphur and aromatics and with a very high cetane number. The hydrocarbons...
