Chennai Petroleum Corporation Limited (CPCL) has commissioned its new 5.8 million gallons per Day (MGD) reverse osmosis (RO) based desalination plant at Kattupalli in Tiruvallur district. The plant with an intake well was located at Bay of Bengal, 500 metres from the landfall point at Ennore. The plant is constructed at a cost of INR2313.4 million.
The sea water at 3,300 m3/hr was pumped to the RO plant facilities located at 3.5 KM from the landfall point.
The new RO plant consisting of four trains has been fully erected and the two streams of pre-treatment section have been commissioned.
The desalinated water would be supplied through pipeline from the plant to the refinery at Manali, which was about 20 KM from the plant.
The laying of pipeline for 18 KM was already completed. The new plant after becoming fully operational would facilitate CPCL to achieve self sufficiency in meeting the current water requirements of its Manali refinery complex as also the requirements of Euro IV/Revamps/Resid upgradation projects, which are under various stages of implementation.
