ZRCC’s Leading Position for Yield of High Value-added Products
Driven
by
the
two
wheels
of
management
and
technology,
ZRCC
has
made
tremendous
efforts
to
address
the
technical
problems
associated
with
the
1MTA
ethylene
plant
so
as
to
increase
the
yield
of
high
value-added
products.
During
the
first
half
of
this
year,
the
yield
of
high
value-added
products
reached
61.87%,
which
is
the
highest
historical
record
and
ranked
first
among
ethylene
plants
of
China.
The
comprehensive
energy
consumption
for
ethylene
product
and
the
energy
consumption
for
high
value-added
products
reached
511.43
and
282.46
kg
standard
oil
per
ton
of
product
respectively,
which
are
both
the
best
records
in
history.
In
order
to
increase
the
yield
of
high
value-added
products,
ZRCC
gave
pull
play
to
the
team
work
of
technical
innovation
experts
group
to
solve
the
operating
problems.
For
example,
they
added
the
tail
gas
pre-heater
to
recover
the
non-condensable
gas
from
the
propylene
compressor
vent
with
the
recovered
propylene
of
150kg/h,
which
corresponds
to
1300t/a
of
propylene
and
additional
benefit
of
RMB6.5
million
each
year.
