Emerson’s Smart Wireless Technology Saves Plant €
¤160,000 Euros in Downtime and Maintenance
RESULTS
•	Prevented production losses of ¤150,000 Euros
•	Reduced need to replace pumps every six months
at a cost of ¤10,000 Euros
APPLICATION

Gas-cleaning tower with a feedwater inlet/outlet system.

CUSTOMER

Chemical plant in Europe.
The plant produces titanium dioxide to enhance the whiteness,
brightness, opacity, and durability of paints, coatings, plastics, and
other consumer products.

CHALLENGE

Plant personnel operated the gas cleaning tower with an overfill drain
that only dumped when the vessel became full of water and sand
settled to the bottom. The water would be displaced, lose proper
dilution, and cleaning efficiency would drop, allowing unknown levels
of hydrochloric acid to be released to the atmosphere. The sand
buildup would also erode ceramic components of the circulating
pump, causing internal leaks and complete failure. Bi-weekly
maintenance to clean the vessel provided minimal improvement to
cleaning efficiency. And, the team still had to replace the circulating
pump every six months to prevent a plant shutdown. Process shut
down for one day for pump replacement is estimated at a production
loss of ¤150,000 Euros ($194,000 USD) and ¤10,000 Euros ($12,886
USD) for pump replacement.
Emerson engineers learned about the gas-cleaning tower challenge
and recommended the installation of a new drain valve wirelessly
controlled using a Smart Wireless solution powered by WirelessHART™
technology.   

SOLUTION

The application required the installation of a new drain valve at
the bottom of the cleaning vessel so that water and sand could be
automated to flush on an as-needed basis. To determine when the
vessel was full and ready to be drained, a Rosemount® 2160 Wireless
Vibrating Fork Liquid Level Switch detected when water levels reached
overfill conditions. The DeltaV™ control system would then send

The first use of WirelessHART
devices has virtually eliminated
downtime in this process and
improved the efficiency of the
gas-cleaning tower.

CHEMICAL
a wireless “open” command to the Fisher® 4320 Wireless Position
Monitor with On/Off Output Control Option to open the turn drain
valve. After 30 seconds, the DeltaV control system would send the
“close” command to complete the draining cycle.  

RESULT

Implemented in December 2011, the project has proven to be a
positive change for the plant. The first use of WirelessHART devices
has virtually eliminated downtime in this process and improved the
efficiency of the gas-cleaning tower. They expect to gain two full days
of production per year and avoid the cost of pump replacements. The
improved performance of the cleaning tower also means the plant is in
compliance with local environmental regulation and is preventing fines
and negative publicity.
The plant still cleans the vessel periodically, but noticed much less sand
in the cleaning vessel, meaning maintenance workers spend less time
in a confined space exposed to chemicals. Worker safety and working
conditions have been improved with the wireless solution.

The Fisher 4320 Wireless Position Monitor with On/Off
Control Output and Rosemount 2160 Wireless Vibrating Fork
Liquid Level Switch were integrated into the DeltaV control
logic to provide traditional automation efficiency, but without
the traditional cost of engineering and installation of wired
instruments and final control elements.
