PTDR Control Systems


PTDR systems are driven by proprietary, state-of-the-art instrumentation and computerized control systems. The Human Machine Interface (HMI) system is the process control system that provides a graphics-based visualization of the system control and monitoring system. The HMI communicates with the process logic control system integrated within a PTDR system. The control system obtains inputs from all of the process subsystems to achieve total overall control of the system. Safety, interlocking features and emergency shut-down aspects specific to each subsystem are incorporated to assure safety features are not compromised.

While the operations can be monitored and controlled using the HMI system, the operator is also provided with a Supervisory Control And Data Acquisition (SCADA) system – a distributed measurement and control system, which includes hardware and software components. Each subsystem has customized interface screens. The SCADA system monitors critical input and output parameters and prompts the operator to make appropriate adjustments (or makes automatic adjustments for critical safety-related conditions) to the waste feed rate, plasma reactor temperature, oxidant input (if required), and the gas cleaning and conditioning system to ensure that the system operates to meet prescribed environmental requirements. The SCADA system also records and logs all events onto a hard disk, which can be printed for further assessment.
