| Description |
With continuous depression in world oil reserves and increasing demand of petroleum products,
the refiners are forced to process more and more heavy crude. On the other hand heavy crude
reserves .are increasing day by day whereas petroleum industry and refinery are facing problems
to drill and to transport the heavy crude from drilling site to refinery to provide a new source of
feed for secondary conversion process and upgrading. For upgrading the heavy feedstocks the
visbreaking process emerges as a cheapest refining tool. This process mainly reduces the
viscosity of the feedstock resulting in lower diluents requirement to meet fuel oil viscosity. In this
process some reduction in pour point is also achieved. Here the soaker mode visbreaking
process has been applied to upgrade the indigenous available heavy crude oil having high wax
contents available in the indigenous (Rajasthan) oil fields with the main objective of reducing the
flow properties of the crude oil making it easy flowable in the pipe Line. The crude oil was
subjected to soaker mode visbreaking at different operating conditions keeping pressure
constant. The operating conditions were optimized at which the produced treated charge was
having maximum reduction in pOllr point limiting to the stable product. It is found that with hollow
soaker pour point waS considerably reduced and it could further be lowered 3°C more using
advanced soaker visbreaking technology i.e. soaker with internals.
