Enhancement of Iraqi Crude Oil Flow in Pipeline System Using Natural Polymer and Nano Fluid Complexes

Abstract

The objective of the present study is to reduce the viscosity of Iraqi crude oil to improve its flowing in pipelines. A new environmentally friendly complexes of natural polymer and nano fluid were used. The new natural polymer is extracted from the aloe Vera plants, while one type Nano fluid of (TiO₂) has been employed with different concentrations. In order to achieve this aim; an experimental work was carried out in 4 m length pipe with five different flow rates using an additives concentration ranged from (100 - 2500) ppm. The experimental results illustrated that the drag reduction of crude oil increased considerably with increasing concentration of additives. It was found that a maximum drag reduction of 78 % was achieved with high concentration (2500 ppm) of the complex mixture of nano fluid and aloe vera plants, while it was 40% and 24% for TiO₂ and natural polymer alone at the same concentration, respectively.
