LIPODAN, a VEOLIA company, is a plant for recycling grease, food grease and used oil which is collected from restaurants, from gas stations, car garages, bus companies and similar locations. The plant treats 12,000 Tons of organic oils and 6,000 Tons of mineral oil per year. For recycling, the plant is using the LIPOVAL process. The oils are first converted to LIPOFIT, an energy-producing fat-concentrate that can then replace fossil fuels in boilers and industrial incinerators.
The LIPOVAL process creates environmental challenges to any measurement equipment. The equipment needs to combat with:
- High temperature – the waste oil is heated to 105°C
- Massive vapors in the tanks
- Dynamic process mixing solids and liquids
SolidAT ultrasonic level transmitters monitor the entire process. Sensors are located at the inlet of waste oil tanks, at the high temperature process tanks and at the product bio-fuel tanks at the end of the process.
The process tanks exhibiting harsh condition that also face high temperature and massive vapors are equipped with SMARTSCAN50. SMARTSCAN50 is one of SolidAT leading level meters. The system is two-part, allowing a low profile sensor on the tank and a control/display unit located conveniently apart at the offices. With SmartScan50, the control/display unit can be located as far as 200 meters away from the sensor. All the tanks are equipped with alarms that are powered by the SMARTSCAN relays. SMARTSCAN50 supports five different relays that may be programmed to trigger at different levels.
Storage tanks at the beginning and end of the process chain are measured by the more cost effective SMARTLITE.
