TL;DR: In this paper, the authors present an overview of the recently commenced CO(2)PipeHaz project focused on the hazard assessment of CO2 pipelines to be employed as an integral part of the Carbon Capture and Storage (CCS) chain.
Abstract: This paper presents an overview of the recently commenced CO(2)PipeHaz project focused on the hazard assessment of CO2 pipelines to be employed as an integral part of the Carbon Capture and Storage (CCS) chain. Funded by the European Commission FP7 Energy programme, the project's objective is to address the fundamentally important and urgent issue regarding the accurate predictions of fluid phase, discharge rate and subsequent atmospheric dispersion during accidental releases from pressurised CO2 pipelines. This information is pivotal to quantifying all the hazard consequences associated with failure of CO2 transportation pipelines forming the basis for emergency response planning and determining minimum safe distances to populated areas. The developments of the state of the art multi-phase heterogeneous discharge and dispersion models for predicting the correct fluid phase during the discharge process will be given special consideration given the very different hazard profiles of CO2 in the gas and solid states. Model validations are based on both small scale controlled laboratory conditions as well as large scale field trials using a unique CCS facility in China, the world's largest CO2 emitter. A cost/benefit analysis will be performed to determine the optimum level of impurities in the captured CO2 stream based on safety and economic considerations. The project will embody the understanding gained within safety and risk assessment tools that can be used for evaluating the adequacy of controls in CO2 pipelines, with best practice guidelines also being developed.

TL;DR: The authors reviewed the available literature and identified the different approaches that are taken to calculate risk in the bowtie method and proposed to allow these variations of the method to exist and be used when applicable, and also proposed that people using the bow tie method give an additional qualification as to whether they are using a qualitative or quantitative variant.

TL;DR: In this article, a review of recent applications of CFD for fire, explosion, dispersions of flammable and toxic materials from accidental releases, incident investigations and reconstructions, and other areas of process safety is presented.
Abstract: In recent years, significant progress has been made to ensure that process industries are among the safest workplaces in the world. However, with the increasing complexity of existing technologies and new problems brought about by emerging technologies, a strong need still exists to study the fundamentals of process safety and predict possible scenarios. This is attained by conducting the corresponding consequence modeling and risk assessments. As a result of the continuous advancement of Computational Fluid Dynamics (CFD) tools and exponentially increased computation capabilities along with better understandings of the underlying physics, CFD simulations have been applied widely in the areas of process safety and loss prevention to gain new insights, improve existing models, and assess new hazardous scenarios. In this review, 126 papers from 2010 to 2020 have been included in order to systematically categorize and summarize recent applications of CFD for fires, explosions, dispersions of flammable and toxic materials from accidental releases, incident investigations and reconstructions, and other areas of process safety. The advantages of CFD modeling are discussed and the future of CFD applications in this research area is outlined.
