Chemicals
based Technologies-Hydrogenation
Process for Manufacturing Specialty Oils and Solvent
An Indian organization developed
a hydrogenation process for manufacturing oils and solvents
from crude oils.
The hydrogenation is done in two stages:-
a) Desulphurisation
- Sulphur content made minimum before starting hydrogenation
using Nickel based catalyst with higher Nickel content
at 200 deg. C. temperature and 40 atmospheric pressure.
b) Hydrogenation
- Hydrogenation was done using Nickel catalyst (5 to
6%) at temperature above than 200 deg. C. and 20 to
40 kg/cm2.
In conventional after getting the
distilled fractions, acid / oleum treatment is given.
Acid used may be 5 to 20%, depending on the product
quality desired. Acid reacts selectively with the unsaturated
hydrocarbons and removes them as acid sludge. If 15%
acid is used, it reacts with almost 15% of oil and about
30% acid sludge is produced. Thus they lose about 15%
of the distilled product and highly acidic sludge is
produced.
As compared to conventional process,
there is no loss of oil during the process and improves
the yield by 0.5 % (approx) as hydrogen is added to
the oil in Hydrogenation process. No acidic sludge formation
during the process. Therefore reduce environmental pollution.
Technical Advantages
Aniline Point achieved in the process
was 83oC, which is acceptable for almost
all the products.
Un Saponiable Residue (USR) value
was achieved up to 87%, which is found satisfactory
for some of the end products, though higher USR Avalue
of 98 and above is required for specialized products
like Rolling oil and ink oil.
