        abstract = {CO2 solid phase formation accompanying rapid decompression of high-pressure CO2
pipelines may lead to blockage of the flow and safety valves, presenting significant hazard for safe
operation of the high-pressure CO2 storage and transportation facilities. In this study, a homogeneous
equilibrium flow model, accounting for conjugate heat transfer between the flow and the pipe wall, is
applied to study the CO2 solid formation in a 50 mm internal diameter and 37 m long pipe for various
initial thermodynamic states of CO2 fluid and wide range of discharge orifice diameters. The results
show that the rate of CO2 solid formation in the pipe is limited by heat transfer at the pipe wall. The
predicted amounts of solid CO2 are discussed in the context of venting of CO2 pipelines.}
