Pressure and temperature increase of LPG in a thermally coated pressure vessel exposed to fire: Experimental and model results

Damage caused by incidents with transport tanks with compressed liquified gas is amongst the most extreme that can be encountered with transport vessels. This is particularly the case with the Boiling Liquid Expanding Vapor Explosion (BLEVE), which may occur if such a tank is exposed to fire for a prolonged period. Therefore, the local Dutch LPG...

Veiligheidsanalyse Resomeren

Uitvaartorganisatie Yarden onderzoekt alternatieve methodes van lijkbezorging voor begraven en cremeren. Eén van de alternatieven is resomeren. Op dit moment wordt onderzocht of dit proces in de nabije toekomst vanuit de sector kan worden aangeboden in Nederland. In Nederland (alsmede vele andere landen) zijn momenteel uitsluitend begraven,...

Thermodynamic aspects of an LNG tank in fire and experimental validation

Mechanical behaviour of a Liquefied Natural Gas (LNG) tank and the thermodynamic behaviour of its containment under extreme heat load - for instance when subjected to external fire source as might occur during an accident -Are extremely important when addressing safety concerns. In a scenario where external fire is present and consequent release...

The influence of risk mitigation measures on the risks, costs and routing of CO 2pipelines

The aim of this study was to analyze whether, and if so, in what way risks would influence the design,costs and routing of CO2pipelines. This article assesses locational and societal risks of CO2pipelinetransport and analyses whether rerouting or implementing additional risk mitigation measures is themost cost-effective option. The models...

CFD dispersion investigation of CO2 worst case scenarios including terrain and release effects

In the present paper, CFD (computational fluid dynamics) computations were performed in order to get insight in heavy gas dispersion behavior based on experimental results and extrapolate them to a representative full bore rupture scenario of a CO2 pipeline. The impact of the release process is investigated on the overall heavy gas dispersion....

Physics of accidental CO2 releases: A lab-scale experimental study

Corrosion of pipe steel in CO2 containing impurities and possible solutions

CO2 flue gases acquired from different sources contain a significant amount of impurities and water, which are corrosive to the pipeline steel. To design the pipelines for large scale of CO2 flue gas transport, the corrosion of pipeline steels has to be investigated in the realistic conditions. In this paper, corrosion behaviour of steel S355...

Validation of OpenFoam for heavy gas dispersion applications

In the present paper heavy gas dispersion calculations were performed with OpenFoam. For a windtunnel test case, numerical data was validated with experiments. For a full scale numerical experiment,a code to code comparison was performed with numerical results obtained from Fluent. The validationwas performed in a gravity driven environment ...

An experimental study on the temperature dependence of CO2 explosive evaporation

The need for transportation and storage of CO2 in bulk quantities is likely to increase in the near future. The handling of CO2 on such scale gives rise to a number of technological challenges and safety aspects. The accidental rupture of a vessel containing liquefied CO2 may lead to a Boiling Liquid Expanding Vapour Explosion (BLEVE). Whether...

Maatwerk onnodig kostbaar

Buiten vastgestelde kaders denken draagt wezenlijk bij aan het verbeteren van onze veiligheid. In Nederland is dit echter uitermate moeilijk. Eerste stap om de huidige praktijk te verbeteren vormt het standaard inschakelen van het RIVM

Assessment of particle size distribution in CO 2 accidental releases

A model was developed to calculate the particle size distribution following the release of pressurised supercritical CO 2. The model combines several sub-models for the different stages of jet break-up and specifically addresses the possible formation of solid particles, which is important for CO 2 releases. The model was validated using...

Computational fluid dynamics study on two-phase CO2 dispersion in a neutral atmosphere

Abstract: A large release of Carbon Dioxide (CO2) is modelled with Computational Fluid Dynamics (CFD), (Fluent v12.1). Special attention is given to the modelling of a neutral atmospheric boundary layer (ABL) with gravity. Both the presence of non-vapour CO2 and the high density of CO2 require that the effect of gravity is taken into account....

Computational fluid dynamics study on two-phase CO2 dispersion in a neutral atmosphere

A large release of Carbon Dioxide (CO<inf>2</inf>) is modelled with Computational Fluid Dynamics (CFD), (Fluent v12.1). Special attention is given to the modelling of a neutral atmospheric boundary layer (ABL) with gravity. Both the presence of non-vapour CO<inf>2</inf> and the high density of CO<inf>2</inf> require that the effect of gravity is...

Op weg naar een schone stad. Urbis III ondersteunt integrale aanpak

Intensivering van ruimtegrbruik door combinatie van transport, bewoning en kantoren is de manier om te komen tot duurzame steden. De praktijk is echter weerbarstig. Het bundelen van geluidscontouren, luchtkwaliteitsnormen en veiligheidseisen in een stedelijk ontwikkelingsplan kost veel hoofdbrekens. Om te komen tot een optimaal ruimtegebruik is...
