Description
FIELD OF THE INVENTION
[0001]
The present invention relates to
marine fuel compositions having low sulfur content and processes for making
such compositions. Herein is provided a low sulfur fuel oil bunker component
having advantageous properties. It also relates to upgrading vacuum residue.
SUMMARY OF THE INVENTION
[0012]
Herein is disclosed a low sulfur fuel
oil bunker component the properties of which essentially correspond to earlier
fuel oil bunker components, except for the sulfur content, which is less than
0.5 wt-% and preferably less than 0.1%-wt. More specifically, the low sulfur
fuel oil bunker component is defined in independent product claim 1. Such low
sulfur fuel oil bunker component provides benefits when used in marine engines.
Compared to use of higher sulfur content fuels, the need for flue gas cleaning
system is avoided. Compared to low sulfur lighter bunkers, the adjustments of
engines due to lower density and/or viscosity are not necessary.
[0013]
The low sulfur fuel oil bunker
component is produced by a novel process. The present low sulfur bunker is
produced by using vacuum residue treated at a solvent deasphalting (SDA) unit
as feed for residue hydrocracking system. From residue hydrocracking, a low
sulfur bunker oil component is obtained as residue. Vacuum distillate is used
as feed, whereby the residue value is increased and hydrocracking residue value
can be improved. Further, the process provides sulfur removal for residues,
which earlier were considered too complex and demanding to be desulfurized as
such. The steps of the present production method are defined in independent
process claim 7.
[0014]
Here is further disclosed a system
suitable for production of low sulfur bunker oil component according to claim 1
and for running process according to independent process claim 7. The essential
elements of the system are defined in independent system claim 12. The
embodiment of said system provide advantages through economical use of feeds
and fractions thereof, enabling better value products and through process
flexibility and adjustability.
BRIEF DESCRIPTION OF THE DRAWINGS
[0015]
The invention will be described in
greater detail by means of preferred embodiments with reference to the attached
accompanying drawings, in which
[0016]
FIG. 1 shows a schematic process
outline for the present process and system. Starting from vacuum residue, a SDA
feed pretreatment is applied before feeding the stream to residue hydrocracking
unit. The residue recovered from residue hydrocracking unit has low sulfur
content and is readily applicable as heavy bunker component;
[0017]
FIG. 2 shows as schematic process
outline the steps preceding the process and system of FIG. 1, and can be
considered as an embodiment of said process and corresponding system. The
starting material for process of FIG. 2 is crude oil. It is subjected to
distillation steps and residue is recovered for further refining;
[0018]
FIG. 3 shows schematically another
embodiment of the present process and system, wherein the process units and
lines in-between are adjustable to two arrangements, one with solid line and
other with dashed line, to provide flexibility.

The brave and
the innovative: History maker Ulla Kiiski
[ EXCERPTS ]
Words: Ninni Sandelius.
You may not have heard the name Ulla Kiiski. But the Finnish scientist’s
breakthroughs in inventing renewable, non-fossil diesel are poised to go down
in history. “Resilience against difficult odds runs in my blood,” she tells
journalist Ninni Sandelius as we kick off our series interviewing the
innovative people leading our industry into a more sustainable tomorrow.
Ulla Kiiski is the scientist whose team is behind the innovation that changed
the course of the global fuel industry. And yet, like Sir Tim Berners-Lee,
inventor of the internet, Kiiski would rather be working than posing for the
cameras, more satisfied with her legacy than with fame and fortune.
Kiiski has worked for 33 years at the research center inside Neste, the Finnish
oil refining company that has become the global leader in renewable fuels.
Among the many patents she holds is one that sounds as unlikely today as it did
23 years ago when her team at Neste hit on it: a renewable, non-fossil fuel
that can power planes, cars and boats.
Now 59, Kiiski is humble and matter-of-fact. And yet, like Berners-Lee or the
scientist and inventor Nikola Tesla, it is just possible that her team’s work
will one day be seen as a turning point in the human story, opening up new
possibilities and striking a decisive blow against climate change.
Ulla Kiiski was born in 1960 into a farming community in Liperi, near Joensuu
in the North Karelia region of eastern Finland. Her parents farmed cattle and
hay, and the children—she was the second-youngest of seven—were expected to
help around the farm.
It was in her later years of secondary school that Kiiski’s fascination with
chemistry—and the journey toward her breakthrough—began. In fact, Kiiski can
pinpoint it to the hour.
She remembers one particular lab assignment, in which she was asked to combine
sodium and chlorine ions to make salt. “It was a revelation to witness how
molecules are composed. I realized that this isn’t difficult. It’s fun and it’s
fascinating!”
She went on to study chemistry at Joensuu, where she joined the research group
of Tapani Pakkanen, a professor who taught physical chemistry, the study of how
matter behaves on a molecular and atomic level, and how chemical reactions
occur. He would go on to become an important mentor and inspiration, and Kiiski
today acknowledges what she calls his “crucial” influence on her future.
Pakkanen led a dynamic team, introducing his students to his network in the
chemical industry. They travelled to conferences and published articles. Under
his supervision, Kiiski completed her master’s thesis in the field of
catalysis.
She recognizes the element of adventure and quest in chemistry—a prospect that
still inspires her to this day. Pakkanen happened to know Outi Krause, the
director of catalysis research at Neste, and the company gave her a grant for
her postgraduate studies. That sealed her future. After two years, she had
finished her degree and became a researcher at Neste’s research center .
The breakthrough
At the beginning of the 1990s, the world had started to change. The Cold War’s
close had opened up new global agendas, and climate change was beginning to
find traction as a reality. The Rio Earth Summit in 1992 showed that more
action was needed. And when the world changed, so did the oil refining
industry. There was a demand for renewable fuels.
At the time, Kiiski was studying catalytic processes—the ways in which
molecules are shaped by catalysts. Part of her job was to compose written
reports on new ventures in the field of oil refining.
In 1993, while working on a report on catalytic conversion of vegetable oils by
hydrogenation, she became convinced that Neste should test this new technology.
She could see the possibly outstanding properties of a new product: The
renewable diesel produced with the technology would contain paraffinic
hydrocarbons and no aromatics, meaning no smell, and was recognized to have
beneficial properties like lower exhaust gas emissions; in short a top-quality
paraffinic diesel. And she knew that Neste could utilize its existing oil
refining technology and expertise in the process development.
Ensio Tukiainen, the director of research at the time, asked the still-young
researcher to share her ideas. Won over by her case, he green-lit the project,
and Kiiski and her colleagues started testing how catalysts would work with
vegetable oils, namely rapeseed oil, known as canola oil in the US, and tall
oil fatty acid.
Soon, they managed to develop a fuel combining good cold properties and a great cetane rating, the number
indicating the combustion speed of diesel fuel and compression needed for
ignition. Kiiski and her colleagues Outi Piirainen and Pekka Aalto filed a
patent application in 1996. Kiiski remembers the day well: It was February 5,
the day commemorating Finland’s national poet, Johan Ludvig Runeberg.
The world catches up
The testing continued after the patent, but there was a break in development,
and the project did not advance to production. “It was the late 1990s, and the
time was just not ripe,” Kiiski says. At the time Neste was also contemplating
the possibilities of first-generation bio diesels.
In the meantime, Kiiski started working in the product development team. But as
the 2000s dawned, the world changed again: The pressure to reduce carbon
emissions became more and more urgent as the data on climate change began to
stack up. “Neste was at a crossroads and decided to take a bold decision toward
manufacturing sustainable fuels,” Kiiski remembers. This restarted the project
around the innovation that Kiiski and the team had patented.
The EU’s Transportation Biofuels Directive in 2003 obliged nations to replace
5.75% of all transportation fossil fuels with biofuels by 2010. The revised
2009 directive introduced a binding target of 10% by 2020. The Finnish national
target is even more ambitious.
These obligations drove changes across the whole energy industry, and in 2002,
Kiiski was working again on the NEXBTL, the technology she and her team had
helped to create. Now she had an opportunity to study the fuel properties of
this remarkable product.
It was time for Neste to take a calculated risk—to move the company in a fresh
direction by investing in this new technology to create renewable fuels. This
was something that was noisily criticized at the time, by investors, employees
and customers alike, but a risk that is now widely recognized as one worth
taking.
In 2007, the company opened a brand-new unit in Porvoo refinery, where Kiiski
was working. Its purpose was to make Neste MY Renewable Diesel, 100% from
various wastes and residues as well as vegetable oils. In addition, it reduces
greenhouse gas emissions by up to 90%.
It turned out to be a smart move. Within a decade, Neste has transformed its
operations to become the world’s largest producer of renewable diesel. It has
made investments worth billions in renewable products, building refineries in
Rotterdam and Singapore. In fact, renewable diesel now brings in the majority
of the company’s revenue.
The power of curiosity
Still, Kiiski is not satisfied with just one successful product. She says she
prefers “handling multiple projects at the same time,” and has her sights set
on new challenges, further breakthroughs.
Within the piles of paper in her office are studies and reports that hint at
the direction in which her thoughts are taking her. Some are on recycling waste
plastics to fuels and chemicals, or on future raw materials such as algae oil
and lignocellulose.

I was intrigued by this article. The subject Ulla Kiiski is extremely
interesting, of course. Beyond that, the article gave me a glimpse into the
role that serendipity plays in the development and commercialization of
innovative products and processes.
You can use serendipity to your advantage. The trick is to go just far enough
down the serendipitous path to inspire creativity, but not so far that you get
nothing done. This is a matter of judgment. And good judgment comes from
experience. So my advice is to just get started … you will know when you are
there.

Sinopec's Hainan refinery delivers first low-sulfur bunker fuel cargo
Sinopec Corp’s subsidiary refinery in the southern island province of Hainan delivered its first shipment of low-sulfur bunker fuel that meets the new International Maritime Organization (IMO) emission rules, state media reported.
A vessel carrying 2,200 tons of the fuel left the Hainan refinery in late February heading to Ningbo on the east coast. The fuel will be put to pilot use at a maritime institution in Shanghai, China Securities Journal reported
The Hainan plant is the second refinery under Sinopec to produce the low-sulfur marine fuel that meets IMO standards. In January, Sinopec Shanghai Petrochemical Corp shipped 6,000 tons of the fuel
IMO will ban ships from using fuel oil with sulfur content above 0.5 percent, compared with 3.5 percent now, unless they are equipped with exhaust “scrubbers” to clean up sulfur emissions, starting 2020

WHY THIS MATTERS
“The International Maritime Organization (IMO) will enforce a new 0.5% global sulphur cap on fuel content from 1 January 2020, lowering from the present 3.5% limit. The global fuel sulphur cap is part of the IMO’s response to heightening environmental concerns, contributed in part by harmful emissions from ships.”

Seatrade Maritime News
What You Need to Know: The 2020 IMO Fuel Sulphur Regulation
[ EXCERPT ]
What It Means for the Refiners
It is without doubt that the 0.5% sulphur rule will have huge implications for the global refining sector in terms of refinery configuration and operations. Simple refineries that produce a substantial share of their crude run into HFO may face margins pressure, while complex refineries may potentially boost margins with a larger production of low-sulphur products.
The International Energy Agency (IEA) mentioned that by 2020 the price of fuel oil is expected to drop in tandem with demand. This will in turn put pressure on (fuel oil) cracks and simple refineries with high fuel oil yields. On the other hand, it could become more attractive to modern, complex refineries who have the secondary units capable of upgrading fuel oil into higher value lighter products.
The IEA stated: “Global refiners will be put under enormous strain by the shifting product slate. If refiners ran at similar utilisation rates to today, they would be unlikely to be able to produce the required volumes of gas oil. If they increased throughputs to produce the required gas oil volumes, margins would be adversely affected by the law of diminishing returns. In order to increase gas oil output, less valuable products at the top and bottom of the barrel would be produced in tandem, which would likely see cracks for these products weaken and weigh margins down.”
The world’s three leading oil majors – BP, ExxonMobil and Shell – have not mentioned anything on a mass production of 0.5% blends, neither have they announced commitments to invest in reconfiguring their crude runs on a global scale to produce 0.5% fuels. “At present, we have not heard of new refinery investments announced as a result of this regulation. It is too early to have that, as IMO’s decision in July will influence many of these uncertainties,” said Serena Huang, research analyst-downstream, Asia Pacific, Wood Mackenzie.
In general, oil majors and refiners are looking to support the shift in bunker fuel demand arising from the new sulphur regulation in various ways. Firstly, refiners can increase ULSFO production by extracting low sulphur fuel oil streams that are currently blended into LSFO or HSFO to be made available to the market as ULSFO. ExxonMobil, for instance, has launched a relatively new product, Heavy Distillate Marine ECA 50 (HDME 50), that can be handled onboard like HFO and has only 0.1% sulphur content.
Secondly, refiners in general have an issue of managing their surplus residue. “In some instances, exploring residue destruction investments may make sense, but this option comes with higher risk on returns of investment, as gas oil demand is predicated on shippers’ uptake of alternative options such as scrubber installation and LNG bunkering,” said Huang.
Thirdly, refiners can raise LNG bunker supplies in major bunkering hubs. In Singapore, Shell and ExxonMobil are working with Maritime and Port Authority of Singapore (MPA) to supply LNG as fuel. In Rotterdam, Shell this year launched a LNG bunker tanker to supply LNG from Rotterdam’s Gate Terminal.
