NRL to cut naphtha use

NRL's 12 MW Steam Turbine Generator (STG) project was taken up considering the huge potential of carbon dioxide (CO2) emission reduction and consequent generation of high amount of Carbon Emission Reduction (CER) value. "Registering of NRL's first CDM project is manifestation of the company's concern about environmental issues which extend much beyond its operational area and addressing concerns which are as important globally," stated a press release.

The 12 MW STG project will capture and utilise the waste pressure energy across steam pressure reduction valves and waste thermal energy of surplus high pressure (HP) steam generated from the various process units of the refinery.

An estimated 8.3 MW power will be generated from waste pressure and thermal energy. "This will ensure reduction in consumption of naphtha, which is being used as fuel in the existing Gas Turbine Generators (GTGs). Total reduction of 41,885 MT of CO2 equivalents per annum has been estimated after implementation of this project," added the release.
