The latest white paper from ORS Consulting 'Quantification of Physical Effects in Relation to Potential Loss of Containment in the CCUS Value Chain' is now published and available for download [see below].
This white paper explores potential loss of containment in the CCUS value chain, focusing on COâ‚‚'s physical effects. It covers release models for liquid and dense phase COâ‚‚, running ductile fracture in dense phase COâ‚‚ pipelines, and potential BLEVE (Boiling Liquid Expanding Vapor Explosion). Each topic includes theoretical insights and engineering guidance, emphasizing the importance of understanding COâ‚‚'s unique properties, such as its ability to exist in gas, liquid, and solid states, and its associated risks.
Main conclusions of the paper are:
The Homogeneous Equilibrium Model (HEM) can estimate COâ‚‚ release rates with the right discharge coefficient.
Pipeline design must include prediction of decompression wave speed to assess running ductile fracture risk. The Battelle two-curve method is unreliable; a semi-empirical approach based on experimental data is recommended.
BLEVE can occur without fire exposure and with non-flammable materials like COâ‚‚. The paper provides guidance on potential COâ‚‚ BLEVE risk regions and conditions.
