“…The releases were performed from approximately 120 bar and 20 • C and resulted in a coldest temperature of −35 • C for the CO 2 mixture containing 10 mole% nitrogen. Also other studies have investigated experimental depressurization of CO 2 pipelines, for the development (Håvelsrud, 2012) and testing (Huh et al, 2014) of multiphase flow simulator OLGA. It was found that the initial pressure drop was well simulated for both pure CO 2 and mixtures, but reliable temperature drop predictions were not provided (Huh et al, 2014).…”

“…The thermodynamic behavior of CO 2 during a rapid depressurization of a pipeline has been experimentally studied (de Koeijer et al, 2009(de Koeijer et al, , 2011Brown et al, 2014;Håvelsrud, 2012;Huh et al, 2014) and simulated using CFD tools (de Koeijer et al, 2009(de Koeijer et al, , 2011Brown et al, 2014;Håvelsrud, 2012;Huh et al, 2014;Witlox et al, 2009;Witlox et al, 2011;Dixon et al, 2012;Calay and Holdo, 2008;Wen et al, 2011;Jie et al, 2012;Munkejord et al, 2010;Lund et al, 2011;Clausen and Munkejord, 2012;Giljarhus et al, 2012;Lund and Aursand, 2012;Munkejord et al, 2013). In order to develop accurate models for predicting the expansion behavior of CO 2 during a rapid depressurization of a CO 2 pipeline, more experimental data is required (Lund and Aursand, 2012).…”

As part of the Carbon Capture and Storage (CCS) process, pipeline transportation of dense phase CO2 is the safest and most economic option for delivering captured CO2 to a storage site .However, in the event of pipeline rupture an enormous mass of CO2 may be released very rapidly, presenting several risks to the pipeline and surrounding population including the significantly increased risk of brittle fracture in the pipe wall. The study of pressure variation and phase change in CO 2 during pipeline blowdown can contribute to the understanding of brittle fracture initiation and propagation, as well as downstream CO 2 diffusion behaviour. As part of the CO2QUEST project, a reusable, industrial scale pipeline experimental apparatus with a total length of 258 m and the inner diameter of 233 mm was fabricated to study CO 2 pipeline blowdown. A dual-disc blasting device was used to remotely control the opening of the pipeline, three different orifice diameters were used in experiments (15 mm, 50 mm and Full Bore Rupture). Different initial conditions in the inventory were achieved by heating the charged * Corresponding author.

Microcellular PETs with High Expansion Ratio Produced by Supercritical CO₂ Molding Compression Foaming Process and Their Mechanical Properties

et al. 2022

Supercritical CO 2 molding compression foaming is an emerging technology for preparing thick microcellular polymer sheets. In a temperature range of 245-255 C and CO 2 foaming pressure range of 5-20 MPa, the molding compression foaming behavior of polyethylene terephthalate (PET) is systematically studied. The maximum expansion ratio of the prepared PET foams is above 30, while the bubble size is only %20 μm. It is observed that during the foaming process, the temperature drop caused by rapid depressurization reaches up to 57 C, which greatly changes the viscoelasticity of PET and limits its foaming behavior. The nucleation and bubble growth behavior of PET is simulated and analyzed based on this change in viscoelasticity. Microcellular PET foams have excellent compression performance due to their smaller cell size and thinner cell wall, and the compression elastic modulus of the prepared microcellular PET sample is twice that of the extrusion foaming PET sample with a similar expansion ratio.
