Continuous, reliable, and representative carbon concentration measurement is vital in CIP and CIL circuits to minimise gold solution losses.

CarbonSense is a fully automated in-situ measurement system that is directly immersed in the slurry, eliminating the need for sample transfer and ensuring optimal carbon management.

According to Outotec, CarbonSense is a robust system that is designed to operate continuously in the agitated area of the reactor to ensure a highly representative analysis. The system features a reference probe to ensure reliable measurement even in changing process conditions.

A single connection cabinet can support up to eight measurement assemblies, along with fibre-optic and copper media connections to the plant network. The system supports virtually any network topology, including star and ring configurations. Maintenance is simplified with all power supplies and fuses located in one place.

The portable calibration unit uses authentic slurry and carbon to ensure excellent results and reliable measurement performance. No recalibration is needed when slurry properties change since the measurement is based on the difference between the measurement probe and the reference probe.

Continuous and reliable carbon concentration measurements minimise gold losses by enabling accurate control over carbon transfer between reactors. The Outotec ACT Carbon Management application is designed to take full advantage of the measurement data.

The system is delivered as a ready-to-install package including measurement assemblies, connection cabinets and analysis software and licenses.

According to Outotec, CarbonSense enables continuous, representative, and reliable carbon measurement; supports development of efficient strategies for advanced CIP/CIL control; has fully automatic operation; is simple to install, operate, and maintain with no moving parts or sample transfer; and can increase safety by helping to avoid blockages and other sampling issues.
