Wireless products prevent lost production

09 December 2008

Emerson's Smart Wireless instruments mounted on a rotating reactor at Coogee Chemical Company, Kwinana, Australia deliver reliable pressure and temperature measurements to prevent frequent reactor breakdowns and lost production time. Control of the process and product quality are greatly improved as a result.

Productivity has increased substantially since the wireless instruments were installed in late 2007, according to Noel Shrubsall, Electrical Project Officer at the plant.

Coogee Chemicals produces a wide range of industrial, agricultural and mineral processing chemicals. Obtaining accurate pressure and temperature data from inside the plant’s rotating reactor is very important to maintaining process control, but wired instruments were not dependable in this environment, Shrubsall said. The failure of seals on the slip-rings connecting wires to the rotating equipment allowed the entry of moisture into the instruments. Unreliable temperature and pressure measurements resulted in poor control of the reactor, which had to be shut down two or three times a week.

“The Smart Wireless solution provides a means of obtaining accurate pressure and temperature measurements from the moving vessel without having to connect wires to the measurement devices,” commented Shrubsall. “Wireless delivers reliability where it wasn’t available before.”

The installation at Coogee Chemicals consists of two wireless instruments mounted on one end of a rotating chemical reactor and transmitting pressure and temperature data continuously to a nearby Smart Wireless Gateway. The data is passed from the gateway via Modbus communications to the programmable logic controller (PLC) controlling the process. More reliable inputs enable the PLC to improve both process control and product quality.

“We are very impressed with this wireless technology, the way it communicates, and its potential for expansion,” Shrubsall said.
