Reply filed by the Chennai Petroleum Corporation Limited (CPCL) in Original Application No 256 of 2020 (Suo Motu Vs Union of India & Others) dated 20/10/2022.

The NGT had taken cognizance of the media article on six industries in north Chennai polluting air for more than half the year.

The industries listed in the media report were the following - North Chennai Thermal Power Station; NTPC Tamil Nadu Energy Company Limited; Chennai Petroleum Corporation Limited; Tamil Nadu Petro Products Limited; Manali Petrochemicals Limited and Madras Fertilizers Limited.

Chennai Petroleum Corporation Limited (CPCL) in its report to the NGT said that the company is taking pollution control measures. Conversion to use regasified liquefied natural gas (RLNG) in boilers, furnaces, gas turbines and hydrogen generation units (HGU) were carried out at the cost of Rs. 312.6 crore since March 2019 in a phased manner as  part of environmental friendly initiative and was completed.

RLNG conversion will have a positive impact on the carbon footprint with reduction in CO2 emissions and will reduce specific feed and fuel consumption for production of hydrogen. This project in addition to the above benefits will reduce SO2 and PM emission considerably.

Low sulphur fuel is being used for process heaters and boilers. Excess O2 in the flue gas is maintained to ensure complete combustion and to ensure prevention of CO emission.
