Claims27
A method for feeding one or more chemicals into a process stream of a papermaking process comprising:
- a. providing one or more mixing apparatuses comprising a first conduit having one or more inlets and outlets;
- a second conduit having one or more inlets and outlets, wherein said first conduit secures to said second conduit and traverses said second conduit;
- a mixing chamber that has one or more inlets and outlets, wherein said second conduit secures to said mixing chamber and wherein said outlets of said first conduit and said outlets of said second conduit are in communication with said mixing chamber;
- and an adaptor that is in communication with said outlet of said mixing chamber and is secured to said mixing chamber;
- b. mounting said apparatuses containing an adaptor over an opening in a thin stock line of said papermaking process;
- c. running said papermaking process so that said process stream flows through said thin stock line of said papermaking process;
- d. introducing one or more chemicals and a feeding liquid into said mixing chamber of said apparatuses by introducing said chemicals or said feeding liquid into said inlets of said first conduit and said second conduit of said apparatuses;
- e. mixing said chemicals and said feeding liquid in said mixing chamber of said apparatuses to form a mixture of said chemicals and said feeding liquid;
- and
- f. dispensing said mixture into said process stream of said thin stock line through said adaptor of said apparatuses that is in communication with said process stream.
