Abengoa to start the construction of a biorefinery producing biofuels from MSW in Nevada
Despite its vulnerable financial position, Abengoa will construct the biorefinery of Fulcrum Bioenergy in Nevada (USA). As
it is widely known, Abengoa filed an insolvency proceeding on November 25,
2015. The debt restructuring plan presented by the company to avoid bankruptcy
included the sale of all non-core assets, such as the first generation biofuels
business units. For instance, if we focus on USA, Abengoa Bioenergy sold its ethanol
plant in Colwich (Kansas) to ICM in August 2016 for 3.1 M$ (more
information about the current status of the facility here: ICM
to build a state-of-the-art biorefinery in Colwich). The crisis also
affected its second generation ethanol business. In fact, Abengoa Bioenergy
Biomass of Kansas sold the Hugoton cellulosic ethanol plant to Synata Bio by
late 2016 for 48.5 M$. The company has been immersed in a deep reform process.

However, yesterday, Abengoa announced having received Notice to Proceed on the construction
of a plant that will convert municipal solid waste (MSW) into syncrude using
gasification technology (see press
release). Abengoa had been selected by Fulcrum to build this biorefinery in
May 2015, shortly before the worsening of its crisis (see blog post: Recent
biorefinery contracts to produce biofuels from MSW in the USA). Prior to
this new announcement, Fulcrum BioEnergy successfully reached financial closure
for the project, this being a prerequisite for the commencement of works. Abengoa
will be responsible for the engineering, design, construction and commissioning
of the plant, which is one of the parts of the Sierra BioFuels Project. Abengoa
has spent over a year working on the preliminary engineering and procurement
works in order to minimize possible risks during construction. I summarize the
available details of the whole project in the following table.
Name of
the project
|
Sierra
BioFuels
|
Location
|
Tahoe-Reno
Industrial Center, approximately 20 miles east of Reno (Nevada, USA).
|
Owner
|
Fulcrum
Bioenergy.
|
Phases
|
- Sierra
Phase One: Feedstock Processing
Facility (FPF).
- Sierra
Phase Two: Biorefinery. There, the
prepared MSW feedstock produced at the FPF will be converted into a
low-carbon syncrude.
- The
syncrude product will then be transported to an Andeavor (formerly Tesoro) refinery to be
further processed into transportation fuel.
|
Feedstock
and processing capacity
|
175,000
tons of Municipal Solid Waste.
|
Product
and production capacity
|
10
million gallons of renewable transportation fuel.
|
Biorefinery
technologies
|
- Gasification (Fulcrum BioEnergy has
licensed the gasification system from ThermoChem Recovery International).
The feedstock
rapidly heats up into a steam-reforming gasifier and almost immediately
converts to syngas. Then, a venturi captures any entrained particulate and
the syngas is further cooled in a scrubber.
The
cleaned syngas is subsequently processed through an amine system to remove
sulfur and carbon dioxide.
Finally, it
enters the secondary gas clean-up section that contains compression to
increase syngas to the pressure required by the next step.
- Fischer-Tropsch process to upgrade the
syngas into syncrude.
The
purified syngas is processed through a fixed-bed tubular reactor where it
reacts with a proprietary catalyst to form three intermediate FT products: a
Heavy Fraction FT Liquids (HFTL), a Medium Fraction FT Liquids (MFTL) and a
Light Fraction FT Liquids (LFTL, commonly called Naphtha).
The
Naphtha is recycled to the partial oxidation unit with remaining tail gas to
be reformed to hydrogen and carbon monoxide.
- Hydrotreating, hydrocracking and
hydroisomerization steps are used to upgrade the combined HFTL and MFTL
products into jet fuel.
|
Investment
|
280 M$.
|
Employment
|
500
construction jobs, 120 permanent jobs and approximately 1,000 indirect jobs.
|
Timeline
|
- The FPF
was completed in 2016 and the facility has been in operations since.
- The
engineering, procurement and construction works of the biorefinery will begin
immediately and are expected to take over two years.
- It is
foreseen that the biorefinery begins operations in 2020.
