| Abstract | ||
| The best performing, most economical and safest is the most desirable triangle in the products used in the petroleum industry. Optimizing the performance of PPD increases the economy of the process; however, excess PPD may have adverse effect. Most of the PPDs have two parts; an oleaginophilic part that co- crystallizes with wax forming components and a polar component that limits the degree of co- crystallization. The present work has main target to study the effect of additives solid contents and composition on the flow characteristics of wax crude oil at low temperature below pour point temperature and paraffin inhibition (PI%). In this respect, different amount of octadecyl acrylate and ethylene vinyl acetate to give different blends with different solid content as follow: PPD-X1(1: 1.4), PPD-X2 (1:0.88), PPD-X3 (1: 1.15), PPD-X4 (1: 1.31), PPD-X5 (1:2) were prepared. These polymeric materials were characterized by FTIR and GPC. The performance of these additives as pour point depressants and flow improver for Egyptian waxy crude oil was evaluated through measurements of pour point paraffin inhibition. It was observed that the PPD-X5 the highest solid content and octa ratio multiple EVA ratio which leads to more effective performance that decrease pour point from 24 to 6 °C with 1200 ppm dose, good handling and highest paraffin inhibition (85 %). | ||
