Carbon capture and storage in the U.S. : a sinking climate solution
Coal-fired power plants produce half of the United States' electricity and are also the country's largest emitter of carbon dioxide, the greenhouse gas responsible for climate change. Carbon Capture and Storage (CCS) is a proposed technological solution that will sequester CO2 in the ground. …

A Comprehensive Dynamic Model of the Column Flotation Unit Operation
… on air fraction is included in the model. Bubble coalescence in the froth is represented as a rate phenomenon characterized by a series of coalescence efficiency rate parameters. Auxiliary equations that help describe the settling of free particles, the buoyancy of air bubbles, and the processes …

Comprehensive Modeling and Numerical Investigation of Entrained-Flow Coal Gasifiers
Numerical simulations of coal gasification process inside a generic 2-stage entrainedflow gasifier are carried out using the commercial CFD solver ANSYS/FLUENT. The 3-D Navier-Stokes equations and eight species transport equations are solved with three heterogeneous global reactions, three …

Towards an ever closer union: with the Turks next door? Is Turkey the ideal energy partner for the EU?
… emissions, improving efficiency and introducing clean coal technology. Within the EU, diverging performance among member states, due to different socio-political and economic factors, threatens the acquisition of 202020 targets. A means of bridging these gaps is to introduce EU-funded subsidies …
