“…In comparison with other research, there is research using the dilution method (adding 20 wt. % of acetone) and the percentage of viscosity decrease was about 21.98%, as well as the use of changing the electric current, the percentage of viscosity decrease was 35.61%, and the two methods were also used together in combination (Dilution and Electrical Field), achieving an optimum viscosity reduction of about 61.856% [6]. The effect of the kinematic viscosity of heavy crude oil on the flow rate for three pipe diameters (i.e., 4, 6, and 8 in.)…”

“…Additionally, it can be concluded that when the pipe diameter increased from 4 to 6 to 8 in., the flow rate and Reynolds number of the crude oil increased in direct proportion, as shown in Eq. ( 2) [6,25].…”

“…Heavy oil transportation through pipelines is much more complicated without reducing the viscosity because a massive energy demand is needed to offset the higher drop in pressure through the pipeline due to high viscosity [5]. Heavy crude oil contains a higher molecular weight of hydrocarbon (HC), with much more than 50 atoms of carbon, which makes the process of refining complicated and expensive [6][7][8].…”

The process of transporting crude oil across pipelines is one of the most critical aspects of the midstream petroleum industry. In the present experimental work, the effect of temperature, pressure drop, and pipe diameter on the flow rate of heavy crude oil have been assessed. Moreover, the total discharge and energy losses have been evaluated in order to demonstrate the improvements potentially achievable by using solar heating method replacing pipe, and adjusting the value of the initial pressure difference. Crude oil of API = 20 has been used for the experiments, with the studied pipelines sections connecting the separator unit to the storage tank operating at a temperature of 25°C-100°C, pressure drop of 3, 4, 5, and 6 kg/cm 2 , and with pipe diameter of 4, 6, and 8 in. The results show that on increasing the temperature and/or the pressure drop, the flow rate through the pipeline becomes higher, thus raising the total pumping energy (as the pipe diameter increase), while energy losses increase from the last separator to the storage tank in the field. A pipe diameter increase can also produce a growth of the total pumping energy (i.e., energy losses increase). The results of the present analysis suggest that employing an optimal temperature (50°C) is needed to ensure good performance.

“…Flow improvement can be achieved by enhancing the fluid-mechanical efficiency of the oil using a material referred to as a flow improver, which significantly reduces the friction of crude oil in oil pipelines, thus reducing pumping energy consumption [8]. Different types of flow improvers and drag reducers can be used in this process, such as surfactants, fibers, and polymers, all of which efficiently reduce the turbulent friction inside pipelines [9][10][11][12]. An electric field can be used to reduce the viscosity and improve the flow of crude oil by applying a specific voltage to the oil for a certain period of time to produce an effective electric field inside the pipe.…”

Graphene flakes (GF) have been prepared and assessed as a material for improving flow in oil pipelines under the effect of an electric field. In particular, different amounts of GFs have been considered in order to determine the optimal flow conditions. The GFs were prepared from graphite foam, derived from the dehydration of sugar with a particle size of 500-600 μm, which was dispersed in ethanol and exfoliated in a ball mill under a shear force. After 15 h of exfoliation, sonication, and subsequent high-speed centrifugation at 3000 rpm, irregular-shaped GFs of 50-140 nm were produced and characterized using scanning electron microscopy, X-ray diffractometry, atomic force microscopy, and Raman spectroscopy. The prepared graphene sheets have been found to display excellent morphology and good graphitic structure. Experiments on flow improvement were conducted using the central composite rotatable design method for three parameters: stimulation time (15, 30, 45, and 60 s), applied voltage (150, 170, 200, and 220 V), and concentration of the GFs (0, 100, 200, and 400 mg/L). The optimal conditions for improved crude oil flow were then determined using the STATISTICA and WinQSB software packages. The results have confirmed the effectiveness of the use of the prepared GFs as a flow improver for crude oil, where the flow improvement is essentially a result of a reduction in viscosity and suppression of friction in the crude oil system.

This review is aimed to explain a comparative survey on the most applicable techniques and methods for increasing the flowability (viscosity reduction) of crude oil since it has defects on transportation, processing, and production due to high power consumption for pumping and corrosion as well as depositing in the pipeline and facilities it is related to the troubles that may occur in processing stream lines in addition to the financial cost associated with transporting crude oil. In this review several techniques have been surveyed including heating, dilution, additives, emulsification, shearing, ultrasonic, and electrical treatment. Based on the present survey electrical methods were reported to be very effective and efficient.
