Abstract: Automation added with intelligent relays and instruments makes implementation of coal leaching pilot plant safe, maintenance free and less dependence upon man power. Two levels of automation have been implemented. Started with data acquisition through controllers overall supervision with supervisory control and data acquisition (SCADA) followed by supervision and data logging by supervisory server have been effectively achieved. Ladder logic programming is done in control logix PLC from M/s Rockwell after building logic sequence, control loops and interlocks of coal leaching process. HART-based instruments are mostly used as field instruments due to smart sensors technology.

Keywords: chemical leaching; supervisory control; data acquisition; SCADA; instrumentation systems; automation systems; coal leaching; pilot plants; data logging; ladder logic programming; PLCs; programmable logic controllers; smart sensors; FTV; factory talk view software; field instruments.
