FCC heavy
naphtha hydrofining technology
to
produce reformer feed
Background
Most sulphides are concentrated in heavy
fractions of FCC gasoline. These fractions are treated
to be the reformer feeds with deep hydrofining by
removing sulfur, nitrogen and other impurities and
having the olefins saturated, which not only resolved
the high sulfur content problem of gasoline, but also
increased the production of reformer gasoline. Belows
are the typical operating conditions:
Pressure:
2.0-8.0MPa
Temperature: 280-320≧
LHSV:
1.5-3.0h-1
H2/oil(v/v):
200-400
Aimed at
Refineries need more reformer feeds and sulfur
content in FCC gasoline is too high.
Main
properties of hydrofined product
S content is less than 0.5ppm,
which can be of quality reformer feeds.
Costs of investment and operation
The implementation of
FCC heavy naphtha hydrofining technology can be based on
revamping existed hydrofining plants.
For constructing a new
plant on a 0.2Mt/a base, capital cost is around USD5.0M,
operation costs is around USD10.4/ton feed (including
hydrogen cost).
