Abstract
A nozzle for injecting a first liquid mass into a stream of second liquid mass flowing within a pipe, comprising a first, outer, cylinder and second, inner, cylinder concentrically arranged about a nozzle axis, securing means for securing the nozzle to a wall of the pipe with the nozzle axis orthogonal to the pipe wall, the nozzle projecting into an interior of the pipe in use, duct means for receiving the first liquid mass and transporting it to the interior of the inner and outer cylinders, the inner cylinder comprising at least one hole arranged to expel liquid therethrough, and the outer cylinder comprising at least one hole arranged to expel liquid therethrough.
Claims16
A method of mixing a liquid flowing in a pipe comprising:
- securing a nozzle to a wall of the pipe with the nozzle projecting into an interior of the pipe, said nozzle comprising:
- a first, outer, cylinder and second, inner, cylinder concentrically arranged about a nozzle axis;
- a first duct adapted to receive a first portion of a liquid mass and transporting the first portion of the liquid mass to the interior of the inner cylinder;
- a second duct adapted to receive a second portion a second portion of the liquid mass and transporting the second portion of the liquid mass to the interior of the outer cylinder;
- the inner cylinder comprising at least one hole arranged to expel liquid therethrough into the interior of the pipe at a first momentum flux ratio;
- and
- the outer cylinder comprising at least one hole arranged to expel liquid therethrough into the interior of the pipe at a second momentum flux ratio;
- connecting one of the first and second ducts to a liquid withdrawal scoop downstream of the nozzle;
- withdrawing the first and second portions of the liquid mass using the liquid withdrawal scoop;
- pumping the withdrawn first and second liquid portions to the interior of the inner and outer cylinders respectively;
- and
- expelling liquid into the interior of the pipe through the holes in the inner and outer cylinders at different momentum flux ratios.
A method of mixing a multi-component liquid composition flowing in a pipe, comprising:
- withdrawing a first liquid mass of the multi-component liquid composition;
- transporting the first liquid mass under pressure to an outer cylinder and to an inner cylinder of a nozzle, each cylinder concentrically configured about a nozzle axis;
- expelling a first portion of the first liquid mass through at least one hole configured to expel liquid from the inner cylinder at a first momentum flux ratio;
- expelling a second portion of the first liquid mass through at least one hole configured to expel liquid from the outer cylinder at a second momentum flux ratio, the first momentum flux ratio being greater than the second momentum flux ratio;
- and
- injecting the first and second portions of the first liquid mass into a flow path of a second liquid mass of the multi-component liquid composition, substantially homogeneously mixing the components of the second liquid mass.
