Process Description
PT Newmont Nusa Tenggara operates a gold mining operation on Sumbawa, a remote site in Indonesia. Four new 28 mega-watt generators discharge hot flute gas contaminated with fossil fuel particulate, which is filtered through a baghouse system consisting of six filtering compartments. Each compartment must be automatically cleaned periodically without interrupting the operation of the system.

There are four baghouses, each having its own control system. All four systems are networked together and to a main HMI computer.

Project Description
Research Cottrell was contracted to provide Bag house filter for the new generation facility. FEC Technologies was selected by Research-Cottrell, as a sub-contractor, to design, build and program the PLC panels to control the filtering process, which included:

• System design
• Design and manufacture of 4 custom control panels
• Develop a redundant processor and power supply system
• Program Allen Bradley PLCs to control the process
• Program Allen Bradley HMI to monitor the process
• Program Wonderware Intouch HMI
• Integrated an interface to both Modbus Plus and Allen Bradley DH+ networks
• Simulated functional test at FEC

All aspects of the system operation had to be tested prior to shipment. As a result FEC developed in depth test procedures. The system was completed on time and in accordance with the customer’s requirements.

System Components

• 8 Allen Bradley PLC5/04 processors set up in 4 redundant pairs
• 2 ProSoft Communication Modules (Allen Bradley to Modbus Plus)
• 4 Allen Bradley Panel View 1400e HMIs
• 4 Custom control panels
