We have no experience from pipline transportation of lime slurry.



But we have put quite an extensive work effort into designing a pipeline transportation system for flyash slurry, so please find enclosed excerpts from an offer that, at best, perhaps could be of some peripheral interest for the general public as a second opinion, even though the project was never realized.





Best regards





John





P.S.

I have not been able to enclose two technical drawings (due to lack of computerlitteracy), but they can be sent directly by e-mail by contacting us on info@nkb.umea.com, or by contacting the internet discussion forum editor wohlbier@bulk-online.com, whom has received copies of the drawings transformed into Adobe Acrobat Reader .pdf files.

It sounds like the pipeline option will be the most economic (provided the hydraulics over the hill are acceptable). The starting point is measuring the rheology of the slurry.

The Rugby pipeline in the UK transports lime slurry over a distance of 90 km.

If you provide me with specific requirements, I could be of more assistance (rob@pcce.co.za) ■

Hello Mike

Slurry rheology is usually measured in a laboratory using either rotational or tube viscometers. The slurry volume required for the measurement depends on the method used. We generally request at least three litres of slurry for the tests.

We also have viscometers for measuring slurry rheology on site but this is normally done for an operating pipeline for auditing/validation purposes or to provide input for the control system.

If you send me your email address I will send you some recent papers describing the Rugby pipeline (the files are larger than the forum limit).

Regards
