Exergy and Economic Analysis of Hybrid Mechanical Vapor Compression and Membrane Distillation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybridization of two or more desalination processes has been identified as an attractive option for improved energy efficiency and recovery rate. To appropriately assess the performance enhancement of hybrid desalination systems, an integrated approach for energy, exergy, economic, and environmental investigations should be adopted. This study

Modeling of freezing processes by an one-dimensional thermal conductivity equation with fractional differentiation operators

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
We have studied the Stefan problem with Caputo fractional order time derivatives. The difference scheme is built. The algorithm and the program for a numerical solution of the Stefan problem with fractional differentiation operator are created.

Impact of operational temperature changes and freeze–thaw cycles on the hydraulic conductivity of borehole heat exchangers

Geothermal Energy, 2021
A large share of the primary energy is consumed to provide space heating. Geothermal energy offers a regenerative alternative. For reasons of efficiency and environmental protection, it is important to ensure the system integrity of a borehole heat ...

Reconstruction of the Past Climate in Southern Portugal from Geothermal Data [PDF]

, 2009
The study of the past climate in the territory of mainland Portugal using geothermal data started in 1996. From an initial set of about 90 temperature logs obtained Portugal, eight were chosen as good for estimating ground surface temperature (GST) in ...

Design and Optimization of a Novel Kalina‐Organic Rankine Cycle System Based on LNG Cold Energy Utilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel integrated system (SDKC‐DORC) that combines a split‐flow dual‐pressure Kalina cycle with a secondary organic Rankine cycle for the synergistic utilization of solar energy and liquefied natural gas (LNG) cold energy.

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that

Solute tracer test quantification of the effects of hot water injection into hydraulically stimulated crystalline rock

Geothermal Energy, 2020
When water is injected into a fracture-dominated reservoir that is cooler or hotter than the injected water, the reservoir permeability is expected to be altered by the injection-induced thermo-mechanical effects, resulting in the redistribution of fluid

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

Cap rock efficiency of geothermal systems in fold-and-thrust belts: Evidence from paleo-thermal and structural analyses in Rosario de La Frontera geothermal area (NW Argentina) [PDF]

, 2016
Cap rock characterization of geothermal systems is often neglected despite fracturing may reduce its efficiency and favours fluid migration. We investigated the siliciclastic cap rock of Rosario de La Frontera geothermal system (NW Argentina) in order to
