A STUDY ON THE INDIGENOUS DEVELOPMENT OF POUR POINT DEPRESSANTS FOR WAXY CRUDES
The production of waxy crude from offshore is coupled with flow assurance challenges due to high pour point of the crude and low temperatures. Below the wax appearance temperature (WAT), wax crystallizes out of the liquid hydrocarbon, which causes the gelation ofoil and increase in viscosity. As...

| Summary: |
The production of waxy crude from offshore is coupled with flow assurance
challenges due to high pour point of the crude and low temperatures. Below the wax
appearance temperature (WAT), wax crystallizes out of the liquid hydrocarbon, which
causes the gelation ofoil and increase in viscosity. As a result wax deposition will not
only reduce the effective flow area but can also lead to complete pipeline blockage in
certain cases.
In order to nmiimize the associated problems for waxy crudes production from
offshore fields assisted by pour point depressants (PPDs), extensive study is required
for the better understanding and limitations of the involved mechanism. Currently
there is no appropriate route map available for PPDs selection and formulation
techniques for offshore production. |
