The influence of temperature, pressure, salinity and capillary force on the formation of methane hydrate
Abstract We present here a thermodynamic model for predicting multi-phase equilibrium of methane hydrate liquid and vapor phases under conditions of different temperature, pressure, salinity and pore sizes. The model is based on the 1959 van der...

Biocatalysis in Ionic Liquid: Degradation of Phenol by Laccase
Abstract The aim of this work was to optimize the reaction conditions for the degradation of phenol in aqueous and ionic liquid (IL)-aqueous solution by biocatalysis using two commercial laccases. In order to evaluate the effect of IL on...

Dedicated Observer Scheme for Fault Diagnosis and Isolation in Instruments of an Anaerobic Reactor
Abstract This paper proposes a dedicated observer scheme for fault diagnosis and isolation in instruments of an anaerobic reactor. An asymptotic observer is proposed for the estimation of the concentration of Chemical Oxygen Demand (COD), the...

Modelling the jetting of dilute polymer solutions in drop-on-demand inkjet printing
Abstract We have developed a simplified jetting model that predicts the printability of dilute, monodisperse polymer solutions in drop-on-demand (DoD) inkjet printing. Polymer molecules are modelled as finitely extensible non-linear elastic (FENE)...

Opportunities for CO2 capture through oxygen conducting membranes at medium-scale oxyfuel coal boilers
Abstract Ecofys and ECN conducted a study commissioned by the IEA Greenhouse Gas R&D Programme to identify the most suitable combinations of medium-scale CO2 sources (1–100 MWth) and capture technologies, with respect to potential and costs (see ...

Feasibility study on the carbonate looping process for post-combustion CO2 capture from coal-fired power plants
Abstract The Carbonate Looping process is a promising technology for post-combustion CO2 capture from power plants by means of CaO in a system of two fluidized bed reactors. The present study focuses on the retrofit with re-powering of an existing...

Alternatives for decarbonizing existing USA coal power plant sites
Abstract A CO2 capture and storage (CCS) retrofit strategy is compared to several repowering strategies for decarbonising existing coal power plant sites. The more promising repowering approaches analyzed seem to be a shift to natural gas via...

Recent development in the HMR pre-combustion gas power cycle
Abstract The focus area of the current HMR phase has been HMR process engineering and fabrication and testing of a small-scale monolith module. A new, less complicated HMR gas power cycle has been developed and benchmarked. The efficiency loss and...

Competition of CO2/H2O in adsorption based CO2 capture
Abstract All flue gases contain water vapour along with carbon dioxide, nitrogen, etc. Vacuum Swing Adsorption (VSA), which has been successfully studied for post-combustion dry CO2 capture in our group, is strongly affected by the overwhelming...
