Commercial debut planned for an FCC process

J
X Nippon Oil & Energy Corp. (JX_
NOE; Tokyo, Japan; www.noe.jx-group.
co.jp) plans to construct the first commercial
plant to utilize its high-severity
fluid catalytic cracking (HS-FCC) technology,
which has been demonstrated to
generate higher ethylene and propylene
yields compared to conventional FCC
technology. The new plant, which could
start operating as early as 2018 at the
company's Kashima Refinery, will have
a processing capacity of 24,000 bbl/d of
crude oil, which is eight times larger
than the semi-commercial demonstration
plant JX_NOE has operated at its
Mizushima Refinery since April 2011
(Chem. Eng., August 2013, p. 10), and
is equivalent to an ethylene capacity
of 300,000 ton/d. JX_NOE will invest
around $500-1,000 million for the project,
which includes the construction of
both the HS-FCC plant and the associated
olefin-conversion unit.
JX_NOE currently supplies 1 million
ton/yr of propylene to the petrochemical
market, and aims to become the leading
propylene supplier in Asia by boosting
this to 1.8-million ton/yr, with 300,000
ton/yr from the new HS-FCC plant and
the remaining 400,000-500,000 ton/yr
from production plants outside Japan.
The company believes the HS-FCC technology
will help strengthen its petrochemicals
production capacity.
The HS-FCC process features a downflow
reactor that has the advantage of
suppressing backmixing, and also results
in shorter contact times (0.5-0.6 s) between
the feed and the catalyst, which
allows higher catalyst-to-oil ratios. The
short contact times also enable the process
to operate at higher (600°C) temperatures
(For more process information, see
Chem. Eng., August 2009, p. 12).

the cost of alternative separation
processes moved a step
closer to commercialization,
as inventys thermal technologies,
inc. (burnaby, b.C.,
Canada; www.inventysinc.com)
received additional funding
from major investors, including
Chevron technology Ventures
llC, the venture-capital arm
of Chevron Corp. (San ramon,
Calif.; www.chevron.com),
and Chrysalix energy Venture
Capital. inventys will use the
additional financing to expand
manufacturing and enable the
deployment of full-scale systems
using its Veloxotherm
gas-separation technology in
late 2016. Veloxotherm is based
on a proprietary, low-pressure
temperature-swing adsorption
(tSa) technology that is said
to achieve a carbon-capture
cost of $15/m.t. - one third the
cost of current post-combustion
methods. (For more details
about Veloxtherm, see Chem.
Eng., January 2011, p. 9). ❏
