Hydrotreated Vegetable Oils (HVO) Biorefineries – The rise of renewable diesel

Publication date: 17/09/2015.
Last update: 22/03/2017.

This is a non-updated summary of a full REPORT ON HVO BIOREFINERIES issued in February 2019. If you are interested, please, follow the link: RESOURCES.

This is the second post of a series about the commercial biorefineries producing advanced biofuels through the world. In the first post, cellulosic ethanol biorefineries were the focal point. Now, Hydrotreated Vegetable Oils (HVO) biorefineries come next. Hydrotreating is an alternative process to esterification to produce diesel from biomass. In fact, HVO are commonly referred to as renewable diesel or green diesel in order to distinguish from Fatty Acid Methyl Esters (FAME), best known as biodiesel. Although, it is important to mention that the synonym Hydroprocessed Esters and Fatty Acids (HEFA) is increasingly used to refer to HVO.

HVO can be produced from many kinds of vegetable oils and fats. This includes triglycerides and fatty acids from vegetable oils, (e.g. rapeseed, soybean and corn oil), tall-oil (a co-product from the pulp and paper industry) and animal fats. In the HVO production process, hydrogen is used to remove the oxygen from the triglyceride producing a mix of linear paraffins, CO2 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 sulfur and aromatics, and with a very high cetane number. HVO offers a number of benefits over FAME, such as reduced NOx emissions, better storage stability and better cold properties. In addition, they can be used in diesel engines without blend walls or the modifications required for biodiesel. Another key point is that jet biofuel, bionaphta and biopropane can be co-produced.

Due to all of the previously mentioned advantages, HVO are a very attractive alternative for diesel engine vehicles and their production has seen a large increase in the last few years. Actually, it is the world’s third largest volume biofuel and its production is growing at a faster pace than the more mature ethanol and biodiesel industries. Because of this, several companies have developed proprietary technologies to obtain this kind of green diesel. Also, it should be taken into account that is possible to transform existing refineries into HVO biorefineries with relatively low investments. Below, a short summary of the main characteristics of these facilities worldwide (this post will be updated on a regular basis with the new facilities).
