CO2 separation is an energy intensive process, which plays an important role in both energy saving and CO2 capture and storage (CCS) implementation to deal with global warming. To quantitatively investigate the energy consumption of CO2 separation from different CO2 streams and analyze the...

COSMO-based process simulations with Aspen Plus/Aspen HYSYS are used, for the first time, to a priori estimate the thermodynamic performance of ammonia absorption refrigeration cycles using ionic liquids as absorbents. This allows not only broadening the criteria set used to select/design ionic...

Growing concerns related to environmental pollution, energy security, and future oil supplies have encouraged the development of large-scale non-petroleum-based alternative fuels, such as bioethanol and biodiesel. Bioethanol made from inexpensive and abundant sources of lignocellulosic biomass,...

Condensed Rotational Separation is a technique in which flue gas is cleaned by condensation of the CO2 and mechanical centrifugal separation. It requires partial purification of CO2 to concentrations above 50% in the flue gas, prior to separation. This purification can be realized with existing...

Three-reactor chemical looping (TRCL) is a hydrogen and electricity production technology with inherent separation of carbon dioxide by use of the iron-based oxygen carrier particles. In this study, an integrated continuous operation test unit (300Wth) using 20wt% Fe2O3/ZrO2as an oxygen carrier...

The change in climate has led to an interest in how this will affect the energy consumption in buildings. Most of the work in the literature relates to offices and homes. However, this paper investigates a supermarket in northern England by means of a multiple regression analysis based on gas...

This paper studies the impact of weather variation on energy use by using 5-minutes interval weather–energy data obtained from two residential houses: house 1 is a conventional house with advanced efficiency features and house 2 is a net-zero solar house with relatively more advanced...

Energy consumption forecasting is a critical and necessary input to planning and controlling energy usage in the building sector which accounts for 40% of the world’s energy use and the world’s greatest fraction of greenhouse gas emissions. However, due to the diversity and complexity of...

Renewable energy in Middle East and North Africa (MENA) region, particular solar energy, can be connected to Europe to provide the Northern neighbouring countries with electricity. To achieve this long term objective, it is necessary to understand the local domestic consumption of electricity in...
