Abstract
This work was focused on an investigating of flow ability of waxy crude oil by nontraditional polymer compound. For this propose, a spirocompound consisted of benzaldehyede and triethanolamine 6,6'-(((phenylmethylene) bis (oxy)) bis (ethane-2,1-diyl)) bis (2-phenyl-1,3,6-dioxazocane) [SB] was synthesized using zeolite as a catalyst. The chemical structure of the [SB] was investigated by FT-IR, TGA,GPC, H1NMR and Mass spectroscopy. The rheological behavior and pour point depression of waxy crude oil were also studied different dosages and temperatures. The results showed a significant reduction in the viscosity at different temperatures and dosages. Moreover, it was noticed a decrease in the apparent viscosity and the Bingham yield value for [SB] 437.7, 367.1, and 307.1 cp and 0.48, 0.39 and 0.31 Pa at 15 ºC, 20 ºC and 30 ºC and concentration 1000 ppm respectively. While the blank experiment displayed 743.1, 694.2 and 607.2 cp and 0.74, 0.69 and 0.60 Pa at the same temperatures. This study included blends between [SB] and the acrylate based polymers abbreviated as (B1, B2, B3 and B4). Furthermore, the rheological behavior and the pour point for these blends exhibited that the blend [B4] shew more reduction in the apparent viscosity than [SB] being alone. The apparent viscosity and yield value for [B4] were; 267.8, 249.2 and 212.7 cp and 0.22, 0.11 and 0.09 Pa at 15ºC, 20ºC and 30ºC and concentration 1000 ppm respectively. The pour point depression (Δpp) of [SB] was 9ºC while the blank pour point was 27 º C and the B4 was achieved the maximum depression in the pour point (Δpp= 18 º C) at a concentration of 1000 ppm. This result means that the addition of [SB] to [B4] showed the most positive synergistic effect.
