Transport of Heavy Oil by Applying of Solar Energy

Crude oil is considered the main source of energy worldwide. Important problems faced by oil transportation methods are spills and unintended releases. Therefore, most technological developments in the field of transportation methods are aimed at reducing emissions, improving efficiency or preventing spills and leaks. Pipeline systems are the safest, most efficient and economical way to transport crude oil. The transportation process suffers from serious problems, such as: asphaltene and paraffin interacting with the structure damages it, pressure drop in the pipes and high energy consumption during pumping. One of the most important economic tasks when transporting oil through a pipeline is to maintain fluidity and reduce the pressure drop along the pipe. This article highlights the latest and most effective development methods that were used to increase the fluidity of crude oil in pipelines, and also examines the possibilities of reducing energy costs for transporting heavy oils and hydraulic resistance of pipelines by creating intermediate solar station devices consisting of a parabolocylindrical concentrator with a tracking system and a solar panel with a converter that increase the safety and environmental friendliness of oil transportation by reducing the risk of accidents. The intermediate solar station uses a renewable energy source and is clean from an environmental point of view, since it does not produce harmful emissions. The use of solar energy as a green alternative to traditional energy carriers makes it possible to increase the productivity of the pipeline by up to 50 %, eliminate energy costs during oil transportation.

Design and task management of a mobile solar station for charging flying drones

This paper provides design and task management of the first stage of a project entitled “Fall-Army Worm (FAW) insect killer”. The project has three main stages: design and energy management stage, flying control of drone stage and detecting and killing FAW stage. The goal of this project is to detect and kill; without chemical methods; a harmful FAW insect which is rapidly spreading in Africa and Asia. This paper focuses on design of the first stage of the system, getting maximum power and controlling the energy of the system. A Photo Voltaic system with energy storage devices is proposed to be the source of power. A new algorithm to control the time scheduling of the killing and detection mission is proposed and its effects on the system’s energy and mission period are studied. A comparison between different methods for tracking the maximum power from PV panels is performed to choose the best (less time and high accuracy) method. The results of simulation indicate the effectiveness of the proposed maximum power tracking and task management system.
