Mr.S.C.Tripathi, Secretary
to Government of India, Ministry of Petroleum and Natural Gas,
unveiling the plaque to inaugurate the New Zero Discharge Plant
of CPCL at CPCL’s Manali Refinery complex on 27.12.2005.
From L to R: Mr.A.Kasturi Rangan, Director (Operations), Mr.R.Sankaran,
Managing Director (i/c), and Mr.N.C.Sridharan, Director (Finance).
Chennai Petroleum Corporation
Limited (CPCL) is the first in the refining sector in the country
to convert city sewage into useful water for refinery operations.
The city sewage is converted into water for industrial use by
state-of-the-art Ultra Filtration and Reverse Osmosis Membrane
Technology.
To ensure Zero Discharge of
treated effluents for the recently commissioned 3 MMTPA refinery,
a new Zero Discharge Plant has been commissioned. The new plant
was commissioned by Mr.S.C.Tripathi, Secretary to Government
of India, Ministry of Petroleum and Natural Gas, at CPCL’s
Manali Refinery complex today (27.12.2005). Mr.R.Sankaran, Managing
Director (i/c), and other senior officials of CPCL were present
on the occasion.
The Rs.10.44 crore plant
has a capacity of 200KL/HR, that is, 1 MGD (1 million gallons
per day). This plant thus enables the use of treated refinery
effluents for the refinery’s process applications.
The conversion of treated
effluent to good quality water, using eco-friendly membrane
process, is superior to conventional chemical treatment process.
The new Discharge plant uses hollow fibre, low pressure, capillary
membranes for Ultra filtration and state-of-art spiral wound
Reverse Osmosis membranes. The water thus produced, is free
of suspended solids, colloids, micro organisms and dissolved
solids.
The use of reclaimed
water, results in substantial savings in chemical consumption
in treating water for our captive power plants; helps in resource
saving of Raw Water which now can be diverted for use by the
city population and avoids discharge of the treated effluents.
