Planes para una nueva biorrefinería de etanol celulósico en Dakota del Norte

By -


New Energy Investors planea la construcción de una planta de etanol celulósico en el Parque Industrial Spiritwood (Dakota del Norte, USA). De acuerdo con medios locales (ver noticia en Grand Forks Herald), la biorrefinería de 13 millones de galones (casi 50 millones de litros) al año de capacidad, será alimentada con tallos y hojas de plantas de maíz y paja de trigo recogidos en un radio de 50 millas (80 km). La planta daría empleo a 40 personas de manera directa y a otras 100 para transporte y servicios. Una vez iniciadas las obras, la planta estaría construida en 24 meses con el comisionado planificado para el 2019.

La empresa ha solicitado 125,000 dólares a la North Dakota Agricultural Products Utilization Commission para un estudio de viabilidad de tres meses. Hay muchos inversores interesados pero todavía no hay inversiones comprometidas y este estudio permitiría asegurar posiciones positivas. La preexistencia de la infraestructura necesaria en el polígono industrial es uno de los puntos importantes a favor del proyecto, De hecho, la nueva biorrefinería se ubicaría junto a la planta de etanol Dakota Spirit de AgEnergy. Otro punto importante a considerar es la generación de ingresos para los granjeros. Actualmente, la empresa está manteniendo conversaciones con ellos para determinar un precio que sea justo y beneficie a ambas partes.

A través de Leifmark, socio tecnológico, New Energy Investors tiene acceso a la tecnología Inbicon Biomass Refinery, un proceso de alta eficiencia que transforma biomasa en etanol y lignina de alta pureza. Con una inversión de 200 millones de dólares a lo largo de 15 años, DONG Energy desarrolló completamente la tecnología Inbicon y construyó la Refinería de Biomasa en Kalundborg (Dinamarca) donde se ha demostrado el proceso. Por lo tanto, la tecnología ya está desarrollada y, ahora, se trata de optimizar el diseño de la planta para el emplazamiento de Jamestown.

Recent news about one of the DOE’s 12 Top Biobased Molecules. Rennovia Inc. and Johnson Matthey Process Technologies announced on July 16 that they have successfully started-up a mini-plant for production of glucaric acid from glucose using jointly developed technology. In March 2014, these companies embarked on a collaboration to develop, demonstrate and commercialize catalytic process technologies for the production of bio-based glucaric acid and adipic acid. Under the collaboration, Rennovia and JM Process Technologies work together in processes based on Rennovia’s technology for the catalytic aerobic oxidation of glucose to glucaric acid and the catalytic hydrogenation of glucaric acid to adipic acid. The final goal of the collaboration is to license a package enabling commercial production of these chemical products. The successful operation of this mini-plant is a major milestone in the journey to achieve this goal. The facility is located at the Johnson Matthey Process ...

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: HVO - Hidrotratamiento (HVO) – Conceptos, materias primas y especificaciones - Hidrotratamiento(HVO) – Ventajas sobre el biodiesel convencional y propiedades - Biorrefinerías de Aceites Vegetales Hidrotatados (HVO) – El auge del diésel renovable - Entradas: HVO                El acrónimo HVO significa en inglés “ Hydrotreated Vegetable Oils ” (“Aceites Vegetales Hidrotratados”) o ” Hydrogenated Vegetable Oils ” (“Aceites Vegetales Hidrogenados”). Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propieda...

Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems. Algal biof...
