Abstract During the operation of pressurised pipelines transporting compressible fluids, line packing is employed as an effective method that uses the pipeline itself as a buffer storage, compensating for fluctuations in the fluid supply or demand. While in large-capacity natural gas transmission systems,...

The Ca-Cu looping process is a promising CO2 capture technology designed to produce H2 and power from a fuel gas. The use of inexpensive and widely available limestone would facilitate the scale up of this technology. This work proposes a novel strategy for packed-bed Ca-Cu looping processes consisting of loading the sufficient amount of CuO to calcine only a well-defined fraction of CaCO3 in every cycle during the transient period until the limestone reaches a residual solid conversion of...

The safe operation of pressurised CO2 pipelines is key to the success of Carbon Capture and Storage as a viable means for tackling global warming. However, given their relatively small number currently in operation, the confident prediction of their puncture size failure probability and how it compares with hydrocarbon pipelines are fundamentally important questions that must be resolved. This paper presents the development and application of a robust statistical analytical technique for the...

A methodology based on the multi-objective optimisation of economic and environmental aspects is presented to support the preliminary design of CO2 transport pipelines employed as part of Carbon Capture and Storage (CCS) systems. Pareto optimal design solutions are determined for a realistic point-to-point CO2 pipeline using Level Diagrams and choosing the Nominal Pipe Size (NPS) as a decision variable. A quantitative procedure entailing the definition of economic and environmental key...

The Calcium Assisted Steel-mill Off-gas Hydrogen production process (CASOH) is able to upgrade and decarbonise blast furnace gases (BFG), which is the main source of CO2 emissions in integrated steel making plants. The three main reaction stages of the process (i.e. H2 production via calcium-assisted water-gas-shift of BFG, Cu oxidation and CO2 sorbent regeneration) have been investigated in a lab-scale fixed bed reactor, using readily available functional materials (i.e. a commercial Cu-based...
