Filtration solution for one of the biggest refineries of Europe - Case Study
AZUD has developed an intuitive, safe and fully autonomous filtration solution for one of the biggest refineries of Europe.
The cooling system is installed outdoors, with variable weather conditions, from - 35°C in winter until the + 35°C in summer.
The source water used for the cooling comes from the river and has a high level of suspended solids. In the system, the filtration process is a key element; it is essential to save the maximum water as possible, as to optimize the use of chemicals in the same.
AZUD has developed a containerized water filtration plant designed to operate in adverse weather conditions. AZUD skid solution was an all in one solution (filters, control, protection and operation elements), which includes Automatic control of temperature, leakages, filtration process. The system is very intuitive and safe system, fully autonomous and independent. It is connected to the main central automation system of the productive process of the refinery.
The filtration system is made up by two AZUD HELIX AUTOMATIC AA systems. The first one filters the make-up water from the cooling tower, and the second filters the flow rate from the side stream. Both systems retain particles equal of bigger than 100 micron, which are eliminated during the backflushing process through the drainage manifold.
Main advantages of AZUD HELIX AUTOMATIC AA system:
- Filtration quality: AZUD disc filters guarantee the quality regardless of the working conditions.
- Fully automatic backflushing, by differential pressure or by time.
- Maximum backflushing efficiency and minimal water consumption.
- Minimal frequency and intensity of the maintenance labours.
