METHODS FOR REMOVING FINELY DISPERSED PARTICULATE MATTER FROM A FLUID STREAM

摘要

Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.

1. A system for removing particulate matter from a fluid, comprising:
a first fluid stream containing particulate matter; an activator polymer that interacts with the particulate matter; a first introducer that inserts the activator polymer into the first fluid stream to form a first treated stream; a second fluid stream containing anchor particles; a tether polymer that coats the anchor particles and that is capable of interacting with the activator polymer; a second introducer that inserts the tether polymer into the second fluid stream to form a second treated stream; a mixing apparatus that mixes the first treated fluid stream and the second treated fluid stream so that the activator polymer binds with the tether polymer to form complexes comprising the particulate matter and the anchor particles; and a separation system that removes the complexes from the fluid.
