Abstract
Methods and apparatus for producing and distributing a slurry of finely divided unagglomerated carbon dioxide particles suspended in liquid carbon dioxide include the production of liquid CO.sub.2 from carbon dioxide gas. A CO.sub.2 slurry is then formed in a reactor by introducing liquid CO.sub.2 therein, agitating the same and concurrently controlling the rate of evaporation. The slurry so formed is pumped to a storage vessel wherein the solids concentration of the slurry may be increased. Slurry is subsequently pumped into a trailer for transport to a customer location with excess CO.sub.2 liquid within the trailer being decanted and returned to the storage vessel thereby increasing the solids content of transported slurry to 60-80 percent. During transport, the slurry is permitted to settle within the trailer and upon reaching a customer location, the settled slurry is reslurried prior to discharge from the trailer. Slurry is then discharged and introduced into a suitable customer storage vessel wherein the slurry is maintained as an unagglomerated suspension of finely divided solid CO.sub.2 particles in liquid carbon dioxide until utilization thereof is desired, at which point slurry is fed to suitable utilization devices.
