Abstract

Apparatus, including a pipeline, featuring at least one pipe liner or coating configured to line or coat a pipe for receiving a process fluid flow, configured with at least one chemical taggant or tracer, and also configured to respond to the process fluid flow, and provide an indication about a degree of liner or coating wear or a location of wear in the pipe. The apparatus may also include the pipe having the at least one pipe liner or coating configured therein.

First claim

What is claimed is:

1. Apparatus comprising:
a pipe configured to receive a process fluid flow; and
at least one pipe liner or coating configured to line or coat the pipe, configured with at least one chemical taggant or tracer, and configured to respond to the process fluid flow, and provide an indication about a degree of liner or coating wear or a location of wear in the pipe, based at least partly on the at least one chemical taggant or tracer;
wherein the at least one pipe liner or coating comprises at least one embedded sensor element configured from the at least one chemical taggant or tracer and formed from a functionalized polymer, and
wherein the at least one embedded sensor element is embedded in the pipe liner or coating, so that by tagging the pipe with different identifiers at different layers or levels within the pipe liner or coating, including with a “sub-tag”, wear progression within specific sections or spools can be detected, determined and monitored, based at least partly on the at least one chemical taggant or tracer detected in the process flow.

2. Apparatus according to claim 1 , wherein the at least one embedded sensor element takes the form of either a functionalized polymer sensor or a sensor made from the functionalized polymer.

3. Apparatus according to claim 2 , wherein the functionalized polymer sensor is configured or designed to respond to the process fluid flow and release a unique chemical taggant or tracer into the process fluid flow containing the indication when in contact with the process fluid flow.

4. Apparatus according to claim 2 , wherein, if the functionalized polymer sensor is embedded at a certain depth in the pipe liner or coating, then as wear of the pipe liner or coating increases, the functionalized polymer sensor will become exposed and release the at least chemical taggant or tracer.

5. Apparatus according to claim 1 , wherein the at least one chemical taggant or tracer is made of a polymer, and fragments of the polymer are collected from a flow stream of the process fluid flow so as to indicate where the wear has reached a critical depth.

6. Apparatus according to claim 1 , wherein the apparatus comprises a monitoring device or analyzer configured to monitor the flow stream at an output of the pipe, detect the at least one chemical taggant or tracer, and determine wear patterns in the pipe.

7. Apparatus according to claim 2 , wherein the functionalized polymer comprises a dual-monomer structure configured to allow the at least one chemical taggant or tracer to be incorporated as a payload/core group.

8. Apparatus according to claim 7 , wherein the payload/core group is configured to incorporate the at least one chemical taggants or tracer.

9. Apparatus according to claim 8 , wherein the payload/core group is configured as a chemical compound, including artificial DNA, also known as Locked Nucleic Acid (LNA), or could be a variety of chemical compounds, including, dyes, fluorescent molecules, nanoparticles, highly specific molecules such as perfluorocarbons.

10. Apparatus according to claim 1 , wherein the at least one chemical taggant or tracer is configured in the at least one pipe liner or coating to indicate properties, selected from a group including the depth within the pipe liner or coating, the circumferential position around the pipe liner or coating, and the linear position along the length of a section of pipe.

11. Apparatus according to claim 1 , wherein the process fluid flow includes tailings forming part of applications in oil sands and hard rock mining.

12. Apparatus according to claim 1 , wherein the at least one chemical taggant or tracer comprises a Locked Nucleic Acid (LNA) or other Synthetic DNA (such as XNA) to create an identifier.

13. Apparatus according to claim 1 , wherein the at least one embedded sensor element comprises beads or strips located within the pipe liner or coating.

14. Apparatus according to claim 1 , wherein the at least one taggant sensor element comprises, or forms part of, a coating polymer matrix applied to an internal surface of the pipe.

15. Apparatus according to claim 14 , wherein the coating polymer matrix is configured to be applied at a certain layer depth, including where the coating is applied on the inside of the pipe during manufacture.

16. Apparatus according to claim 1 , wherein the at least one embedded sensor element is embedded in the pipe liner or coating, so that each pipe section or spool can be identified by a specific tag.

17. Apparatus according to claim 1 , wherein the at least one chemical taggant or tracer is configured and selected to provide a high level of potential identifiers for a given pipeline, including by utilizing a synthetic DNA, so that a large number of identifiers or sequences are available.

18. Apparatus according to claim 1 , wherein the at least one pipe liner or coating comprises at least one pigment.

19. Apparatus according to claim 18 , wherein the at least one pigment comprises at least one material that provides color, including yellow, red, blue and green.

20. Apparatus according to claim 19 , wherein the color is configured from mix formulations of each pigment.

21. Apparatus according to claim 20 , wherein the mix formulations of each color includes:
formulations of about 0%, 33%, 66% or 100% of each so as to produce 256 combination of different colors; or
formulations of about 0% or 100% of each so as to produce 16 combination of different colors.

22. Apparatus according to claim 18 , wherein the at least one pigment forms part of a colorimetric approach for a wear encoding.

23. Apparatus according to claim 22 , wherein the colorimetric approach includes each ‘color’ encoding a different pipe section for indicating that a critical depth had been reached.

24. Apparatus according to claim 18 , wherein the at least one pigment is made of a polymer, and fragments of the polymer are collected from a flow stream of the process fluid flow so as to indicate where the wear has reached a critical depth.

25. Apparatus according to claim 24 , wherein the apparatus comprises a pigment detection device configured to collect the fragments of the polymer from the flow stream of the process fluid flow and determine where the wear has reached the critical depth.

26. Apparatus according to claim 21 , wherein a plurality of colors, including primary or composite colors, are encoded into different depth layers of the pipe liner or coating applied to an inner wall of the pipe, including where each layer is given a different pigment combination, including where each layer is poured and set, sprayed or cast depending on the manufacturing process.

27. Apparatus according to claim 21 , wherein the mix formulations form part of a colorimetric approach used to detect wear with a resolution via colorimetric observation of an internal coating surface of the pipe.

28. Apparatus comprising:
a pipe configured to receive a process fluid flow; and
at least one pipe liner or coating configured to line or coat the pipe, configured with at least one chemical taggant or tracer, and configured to respond to the process fluid flow, and provide an indication about a degree of liner or coating wear or a location of wear in the pipe, based at least partly on the at least one chemical taggant or tracer,
wherein the at least one pipe liner or coating compris
