Point of Solar Heat Integration |
B2) Heating of process medium (please specify)
|
|
--> Integration how and where |
The solar system contains three circuits; the primary circuit between the solar collectors and the solar heat exchanger, secondary circuit between the solar heat exchanger and storage tank, and the tertiary circuit between the storage tank and the process heat exchanger where the process medium is being heated
|
|
--> Temperature range process |
The solar heat is delivered at a temperature range from 20 – 50 °C
|
|
--> Temperature range solar loop (min/max), C° |

Lessons learned |
|
|
Initiative |
The project start up is a joint effort between HCM and MEI. This project is constructed as a pilot, and aims to increase copper extraction from the ore by using warmer leaching fluid heated up by solar system instead of conventional heating source.
|
|
Integration methodology |
The solar system is a standalone system not connected to conventional heating system.
|
|
Crucial Interfaces |
Most critical issue during design stage is to determine the storage capacity required for the system.
|
|
Construction / Commissioning |
Insure proper compaction and stability of ground for solar matrix land installation to avoid any settlements and misalignment in collectors.
|
|
Operation / Performance |
The system is in operation since march 2013. System data will be analyzed for performance in future.
