ABSTRACT
The applicability of blending technique in an offshore transportation of a Nigerian waxy gas condensate has been studied. Experimentally, chemically treated and untreated wax-ladden gas condensate samples were blended with non-waxy crudes in the range 15 - 50% of the condensate. This was followed by measurement of the rheological properties and waxing tendencies of the resulting blends.
At all the test temperatures (60 - 100°F), increased proportion of treated condensate samples in the blends has a reducing effect on the pour point and waxing tendencies of the blends. However, for those blends with untreated condensates, significant increases in these parameters are observed.
Also, viscosities of blends showed a greater reduction at higher proportion of treated than untreated condensate samples.
All these trends appear to re-affirm the feasibility for improved pipeline transportation of treated gas condensate as blends.
