Abstract

Of the total oil and gas supply, a significant share is transported through pipelines. Ultimately the level and quality of cleanness of pipelines greatly affect the transportation of oil and gas. Considering this, any obstacle in the pipelines will delay the transportation process and will consequently reduce the amount of oil and gas transported at a high cost. Remarkable issues that are related to black powders are the contamination of product, reduction in flow of oil and gas, and environmental hazards.

The main objective of this paper is to gain familiarity with the phenomenon of black powder, and based on the analysis design and builds a magnetic Nanoscale filtration/sorption system for crude oil treatment. A magnetic separation system is used for removal of iron and heavy metals from crude oil. The prime function of the radial field magnetic separation system is the breaking-down of black powder particles to submicron levels in full flow. Moreover, the paper has studied the enhancement of nanoparticle technology by using the graphene nanoparticles to improve the separation efficiency of the magnetic separation system. The graphene nanoparticles have enhanced the magnetic separation system. The resistivity meter has been used to measure the resistance of the oil, before being contaminated with black powder and after, in each step of the experiment. It has been observed that higher resistance leads to lower values of black powder.

The analysis suggests that one stage of magnetic separation is more efficient than two stages. Measurement shows that with one stage magnetic separation procedure, the resistance of the oil sample, with black powder, increased from 2157 kΩ to 2969 kΩ, before and after the magnetic separator. The separation of black powder has estimated by 22%, and the magnetite material decreased by 16 gm. However, the resistance of the oil sample, with graphene nanoparticles, increased from 1799 kΩ to 2661 kΩ, before and after the magnetic separator. The separation of black powder has estimated by 24%, the amount of the magnetite material decreased by 19.58 gm. The 2% increase in the efficiency of the system can be attributed to the use graphene nanoparticles.
