Fouling in heat exchangers is the unwanted buildup of material on the heat exchange surface which reduces thermal efficiency. The crude preheat train usually consists of a set of heat exchangers which tend to become fouled. Crude oil fouling can be…
Concentrating solar power (CSP) plants have been widely commercialized for generating electricity from solar energy. Thermal energy storage (TES) systems have been deployed as a key component in CSP plants for resolving the supply-demand gap during…
The solidification process in a multi-tube latent heat energy system is affected by the natural convection and the arrangement of heat exchanger tubes, which changes the buoyancy effect as well. In the current work, the effect of the arrangement of…
Fouling phenomena, generally related to heavy crude oils and bituminous petroleum fractions, nevertheless affects significantly the preheat train (PHT) of the light Algerian crude oil. In this study, a two dimensional model was developed using the…
The application of thermal energy storage using thermochemical heat storage materials is a promising approach to enhance solar energy utilization in the built environment. Potassium carbonate (K2CO3) is one of the potential candidate materials to…
Electrical energy storage (EES) systems consisting of multiple process components and containing intensive amounts of energy present inherent hazards coupled with high operational risks. Although the thermal hazards of batteries have aroused…
One of the important challenges in city gate gas pressure reduction stations is the heating of the natural gas prior to pressure reduction. Regarding the low efficiency of the common water bath heaters in these stations another type of double…
Coil-wound heat exchangers (CWHEs) have been widely used in natural gas liquefaction plants nowadays. But few studies on the condensation heat transfer and frictional pressure drop of mixed hydrocarbon refrigerants inside the tubes of CWHEs have been…
In crude oil refineries, fouling in heat exchangers and heat exchanger networks represents one the most complex and challenging issues. Its occurrence produces major impacts in thermal, hydraulic and economic performance on every heat transfer…
In liquefied natural gas (LNG) production, the total efficiency of the system increased by using mixed refrigerants for the liquefaction process. In this study, the mixing of the effective refrigerants is considered as one of the most important…
Nowadays, maintenance is based on the synergistic integration of operational reliability and timely maintenance, which guarantees the required availability and optimal cost. Operational reliability implies producing more, better performance, longer…
According to Eni's mission to reach carbon neutrality in the countries where it operates, the development of renewable energy could be a key element in the company's strategy for evolving the business model towards a low carbon scenario. In this…
A new geothermal energy-assisted natural gas hydrate recovery method (GEAN) that can simultaneously exploit geothermal energy and natural gas hydrates (NGHs) by injecting water into a geothermal heat exchange well was proposed in this paper. GEAN…
Multi-component refrigerant compression refrigeration cycles have a high coefficient of performance and difficult controllability. In these systems, it is not easily possible to keep the ratio of stream compositions constant in the event of a leak.…
The paper describes a method for increasing a yield of stock-tank oil by reducing liquid carryover with associated petroleum gas at crude processing facilities (CPF) of one oil field in Iraq by cooling the feed stream in air cooled heat exchangers.…
