Abstract
An insulated solution injector may include an outer tube and an inner tube arranged within the outer tube. The outer tube and the inner tube may define an annular space therebetween, and the inner tube may define a solution space within. The annular space may be configured so as to insulate the solution within the solution space. As a result, the solution may be kept to a temperature below its decomposition temperature prior to injection. Accordingly, the decomposition of the solution and the resulting deposition of its constituents within the solution space may be reduced or prevented, thereby decreasing or precluding the occurrence of a blockage.
Claims8
A method of injecting a solution into a high temperature liquid stream, the method comprising:
- inserting an injector into a pipe configured to carry a flow of the high temperature liquid stream, the injector configured to deliver the solution into the high temperature liquid stream, the injector including an outer tube and an inner tube arranged within the outer tube, the outer tube and the inner tube defining an annular space therebetween;
- insulating the solution from the high temperature liquid stream while the solution is in the injector;
- injecting the solution into the high temperature liquid stream;
- and
- shielding the solution from a full velocity of the flow during the injecting, the shielding occurring on an upstream side of the injector relative to the flow after the solution has been injected into the high temperature liquid stream.
