| INDMAX: Residue Upgradation to LPG, Light Olefins and high Octane Gasoline
|
|
 |
 What
is INDMAX Technology? |
 |
INDMAX Technology is a novel process developed by IOC R&D
Centre for upgrading heavy hydrocarbon into LPG, light olefins
and high-octane gasoline in the presence of a proprietary catalyst
in a fluid bed reactor/ regenerator system.
|
What
is the feedstock for a INDMAX unit? |
|
The feed stock of INDMAX unit is heavy hydrocarbon residue which
includes Short Residue (SR), Reduced Crude Oil (RCO) and Heavy
Vacuum Gas Oil (HVGO).
|
What
are the products of INDMAX unit? |
|
The products of INDMAX unit is mainly liquefied Petroleum Gas
(LPG 40-65 wt% of fresh feed) containing high quantity on olefins
such as Propylene (17-25 wt% of fresh feed) and butylene (20-28
wt% of fresh feed). It also produces high octane (95+) gasoline.
|
What
are the advantages of INDMAX Technology? |
|
The advantages of INDMAX Technology are
| » |
Up gradation of low value
heavy hydrocarbons into high value LPG and light high
octane distillates |
| » |
Can process feedstocks
with CCR level of 5.0 wt% . |
| » |
Catalyst can withstand
the high metal level in the feed specially vanadium. |
| » |
Process is economical and
gives better return on investment. |
|
How
is INDMAX different from FCC/ RFCC? |
|
INDMAX is different to FCC/RFCC on the following aspects
| » |
In the case of INDMAX Cat/
Oil Ratio is very high (15-25) as compared to FCC/RFCC
(4-7) which ensures heat transportation from regenerator
to reactor. |
| » |
The reaction temperature
is high (550-570ºC) |
| » |
The catalyst composition
is also different from FCC/RFCC. |
|
How
is INDMAX different from DCC? |
|
INDMAX differs from DCC as it produces more yield of LPG, light
olefins and middle distillates and reduces yield of coke, dry
gas and bottom. INDMAX operates at high cat/ oil ratio (15-25)
whereas DCC operates at low cat/ oil (7-12). Also reactor pressure
is low in the case of INDMAX.
|
What
are the characteristics of the catalyst used in INDMAX? |
|
INDMAX employs proprietary catalyst, which has three synergistic
multifunctional components. The bottom-cracking component upgrades
bottomand shape selective component allows selective cracking
to light olefins without increasing the coke and dry gas make.
The third component contains ultra-stable Y zeolite, which shows
synergistic effect with the other two components of the catalyst. |
