“…The authors ' review [3]- [12] highlights the methods currently used to increase the fluidity of heavy crude oil in pipelines by improving rheology, in particular, heating, dilution, oil-inwater emulsion, as well as modernization and annular flow of the core were considered. A method for determining the boundary conditions of heavy oils using combined methods of heating, water mixing and dilution is proposed, and a set of simple diagrams of solutions of boundary conditions for heavy oil is described.…”

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.

“…Improved crude oil transportation using pipelines can be achieved by reducing the viscosity of the crude oil to enhance the followability of oil via pipelines. Several techniques have been demonstrated to improve the crude oil flow properties through pipelines by reducing crude viscosity [1][2][3][4][5] The blending and the dilution technique is based on decreasing the viscosity of heavy crude oil by mixing the oil with another oil having a lower viscosity. The diluent may be light crude oil [6][7][8], naphtha [9,10], alcohol [7,9], condensate [10,11] or kerosene [6].…”

The present work aims to retrofit an existing Egyptian oilfield plant to improve desalter performance and reduce the power of crude oil shipping pumps. In this work waste heat in disposed water that represents a value is used in heating brackish water injected over desalter and in heating crude oil before shipping. ASPEN HYSYS version 11 simulation software was used. The retrofit of the considered oilfield plant is based on the implementation of two new heat exchangers to recover waste heat in the disposed water. The results showed that the use of waste heat in heating the brackish water in the desalter from 30 to 71.11?C will increase the operating temperature of the desalter and thus increase the sedimentation and separation rate. On the other hand, using waste heat in heating the crude oil before shipping from 37.78 to 71.11?C reduces the oil viscosity from 1.536 to 0.9735 cSt. Reducing the viscosity of the crude oil will reduce the pressure drop of the shipping pumps, and therefore the power required to pump the oil will be reduced. The presented retrofit design can be used as a guide in upgrading existing plants and plants under the design phase.

“…Without prior viscosity reduction of heavy crude oil, transportation through pipelines is very difficult because of the tremendous energy required to overcome the high-pressure drop in the pipeline due to the high viscosity [4]. Generally, there are different methods used to enhance the transportation of viscous petroleum through pipelines that include heating, dilution, and electric field [5].…”
