Abstract
Methods and systems for forming a particulated solids-carrier liquid slurry and transporting it through a conduit are provided wherein a continuous stream of carrier liquid is flowed into a sump, particulated solids to be transported are introduced into the sump so that a pumpable solids-carrier liquid slurry is formed therein, and the slurry is pumped out of the sump into a conduit for transport to a remote location. The flow rate of the stream of carrier liquid flowing into the sump is varied in inverse proportion to changes in the flow rate of particulated solids introduced therein so that the flow rate of slurry formed in the sump is maintained substantially equal to the flow rate of slurry pumped out of the sump.
