Summary

The primary objective of this investigation is to obtain experimental data that can be applied to assess the technical feasibility and the environmental impacts of oceanic containment strategies to limit atmospheric emissions of carbon dioxide from coal and other fossil fuel combustion systems. These strategies exploit the very large storage capacity of the deep ocean. In most systems proposed to date, CO₂ extracted from a combustor is liquefied and transported to the deep ocean via a submerged conduit and discharged, usually as a jet. Hydrodynamic instability induces break-up of the jet into droplets which will be buoyant at depths above 3,000m. Dissolution of the rising droplets may be inhibited by a solid hydrate film that forms on the surface of the droplets. The complex mechanisms of liquid CO₂ jet break-up, droplet dispersion and coalescence, and dissolution in the deep ocean environment are not well understood. The present investigation seeks to address several of the major technical uncertainties by conducting two categories of laboratory tests which will: (1) characterize size spectra and velocities of the dispersed CO₂ phase in the near-field of the atomized jet; and (2) estimate rates of mass transfer from single rising droplets of liquid CO₂ encased in a thin hydrate shell.
