The TFM Active Lime Plant is a supporting facility for the Tenke Fungurume Mining (TFM) copper-cobalt mining complex in the DRC. The lime plant was constructed to meet TFM's internal demand for lime in the copper-cobalt beneficiation process, eliminating the need for costly third-party imports.
The lime plant project began construction in January 2020 and successfully achieved ignition on October 27, 2020. With a production capacity of 600 tons of quicklime per day, the facility includes a rotary kiln and auxiliary equipment where continuous temperature and pressure monitoring is required for stable operation, product quality and process safety.
In 2024, Anhui Tiankang Group was selected as the instrumentation supplier for the lime plant's operational and maintenance needs, providing temperature and pressure measurement instruments through the project's purchasing channel.
High Temperature Process Measurement Requirements
Lime production equipment operates at elevated temperatures, requiring temperature sensors capable of withstanding extreme heat while maintaining measurement accuracy and long-term reliability. The harsh environment demands robust sensor construction with appropriate materials and protection.
Corrosive Process Conditions
The lime production process involves alkaline materials and high-temperature combustion gases, demanding instruments with appropriate material selection for corrosion resistance. Standard materials may fail prematurely, making material selection critical.
Remote Site Logistics
The project site is located in the DRC's Lualaba Province, requiring robust export packaging, shipping coordination, and documentation to ensure instruments arrive in good condition.
EPC Documentation Requirements
Complete technical documentation, including calibration certificates and material test certificates, was required for all supplied instruments to meet the project's quality assurance standards.
Anhui Tiankang Group supplied a comprehensive temperature and pressure instrumentation package for the TFM Active Lime Plant.
