linear models for optimization of infrastructure for hbox co _ 2 capture and storage
IEEE Transactions on Energy Conversion, 2008Co-Authors: B H Bakken, I Von Streng VelkenAbstract:This paper presents linear models of the most common components in the value chain for capture and storage. The optimal investment planning of new gas power Plants traditionally includes the cost of fuel versus sales of electricity and heat from the Plant. If a new power Plant also causes additional investments in gas infrastructure, these should be included in the optimization. With the increasing focus on global emissions, yet another aspect is introduced in the form of technology and infrastructure for capture, transport, and storage of . To be able to include all these aspects in the planning of new power Plants, linear models for capture and storage are formulated consistent with current models for gas, electricity, and heat infrastructures. This paper presents models for the following infrastructure: source, combined cycle gas turbine producing electricity, heat and exhaust, capture Plant, Pipeline, liquefaction Plant, storage, ship transport, injection pump, and demand/market.

quantifying the efficiency of a mono port diffuser in the dispersion of brine discharges
Desalination, 2017Co-Authors: Angel Loyafernandez, Luis Miguel Ferrerovicente, Candela Marcomendez, Elena Martinezgarcia, Jose Zubcoff J Vallejo, Jose Luis SanchezlizasoAbstract:Abstract Reverse-osmosis seawater desalination processes produce a hypersaline effluent waste (brine) which is usually discharged back into the sea via an underwater outfall. Brine discharges can cause environmental problems due to their high salt concentration, but the effects can be minimised by installing a diffuser structure at the end of the Pipeline. In May 2010, a mono-port diffuser was installed at the Nuevo Canal de Cartagena desalination Plant Pipeline (located in Murcia, Spain) in order to increase effluent dispersion. The aim of this paper was to characterise the brine-plume dispersion throughout a series of oceanographic surveys that were carried out before and after the diffuser installation (2006–2011), and to quantify the effects of the diffuser on the behaviour and dilution rate of the effluent. The results of six years of operational monitoring were also compared with simulations predicted by a numerical mixing model simulation (CORMIX 1), obtaining high concordance with field data. After the diffuser installation, both field data results and model simulations showed a strong increase in the dilution rate of the brine plume, and a significant reduction in the size of the affected area.

safety assessment based on mapping of degraded mechanical properties of materials for power Plant Pipeline using instrumented indentation technique
Journal of Loss Prevention in The Process Industries, 2009Co-Authors: Kyungwoo Lee, Kughwan Kim, Juyoung Kim, Kwang Ho Kim, Byunghak Choi, Dongil KwonAbstract:The remaining life prediction of those is accomplished by accelerated degradation tests such as creep testing. However, creep testing is both time-consuming and expensive and hence impossible to apply under industrial conditions, where prompt management and analysis are necessary. While residual lifetime predictions and safety assessments of power Plant facilities are made using standard mechanical testing methods such as uni-axial tensile and fracture mechanics tests. However, these tests cannot be applied to in-service structure components because of their destructive nature. A nondestructive instrumented indentation technique is thus attractive for investigating the mechanical properties of in-service systems. This technique can measure flow properties by analyzing indentation load-depth curves reflecting the deformation behavior of the material beneath the rigid spherical indenter. In this study, heat treatment was used to produce degraded samples of X20CrMo12.1V and SA-213 T23, materials widely used in power Plant Pipelines, and their mechanical properties versus degree of degradation were evaluated by instrumented indentation. We assess the degradation of mechanical properties by microstructural analysis and discuss the possibility of appraising the safety of power Plant facilities by in-situ monitoring of mechanical properties using instrumented indentation testing.

boom and bust 2017 tracking the global coal Plant Pipeline
2017Co-Authors: Christine Shearer, Nicole Ghio, Lauri Myllyvirta, Ted NaceAbstract:The number of coal-fired power Plants under development worldwide saw a dramatic drop in 2016, mainly due to shifting policies in Asia, according to a new report released today by Greenpeace, the Sierra Club, and CoalSwarm. The report is the third annual survey of the global coal Plant Pipeline. Its findings include a 48% decline in overall pre-construction activity, a 62% drop in new construction starts, and an 85% decline in new Chinese coal Plant permits. Reasons for the rapid fall-off include a dramatic clampdown on new coal Plant projects by Chinese central authorities and financial retrenchment by coal Plant backers in India. In China and India, construction is now frozen at over 100 project sites. In addition to the decline in new Plant development, the survey also found a record-breaking 64 gigawatts of coal Plant retirements in the past two years, mainly in the European Union and the U.S. — the equivalent of nearly 120 large coal-fired units (see note). According to the report, the combination of a slowed new coal Plant Pipeline and an increase in outdated coal Plant retirements brings the possibility of holding global temperature increase to below 2°C above pre-industrial levels “within feasible reach,” provided countries continue to step up action.
