Corrosion of transport pipelines for CO2–Effect of water ingress
Abstract Both field experience and lab data indicate that the corrosion rate of carbon steel in pure dense phase CO2 is near zero if no free water is present. The question is whether this also applies when other contaminants like SO ...

Dispersion Effects on Mixed Convection over a Vertical Wavy Surface in a Porous Medium with Variable Properties
Abstract In this paper, the dispersion effects and variable properties on mixed convection over vertical wavy surface immersed in a fluid sat- urated Darcy porous medium are considered. The governing equations are transformed into a set of ordinary...

Equilibrium Model of Steam Gasification of Coal
Abstract Coal gasification is a complex process of parallel-consecutive chemical reactions at high temperature between the organic part of coal matter and the gasifying agent. The following two approaches are applied in modelling the coal...

Electricity-based plastics and their potential demand for electricity and carbon dioxide
Abstract In a future fossil-free circular economy, the petroleum-based plastics industry must be converted to non-fossil feedstock. A known alternative is bio-based plastics, but a relatively unexplored option is deriving the key plastic building...

Making CCS Pay for Itself: Storage Strategies in Geopressured-Geothermal Aquifers
Abstract Development of the current approach to carbon capture and sequestration from coal-fired power plants has several technical, environmental and economic constraints. Production of brine while storing CO2 in the aquifer greatly mitigates some...

Kinetics of oxygen uncoupling of a copper based oxygen carrier
Abstract Here, an oxygen carrier consisting of 60wt% CuO supported on a mixture of Al2O3 and CaO (23wt% and 17wt% respectively) was synthesised by wet-mixing powdered CuO, Al(OH)3 and Ca(OH)2, followed by calcination at 1000°C. Its suitability for...
