Combined Effect of Depressor Additive and Heat Treatment on the Rheological Properties of Highly Paraffinic Oils.

The transportation of paraffinic oils, particularly from Kazakhstan, is hindered by the formation of asphalt-resin-paraffin deposits (ARPDs), which complicate production and transport processes. While chemical treatments using inhibitors and depressants are commonly used, they are often less effective for oils with high paraffin contents and unique compositions, such as those found in Kazakhstan. This study presents a novel approach to synthesizing a depressor additive (PTE) tailored specifically for paraffinic oils, addressing the limitations of existing commercial additives.
