To reduce the total gross emissions of natural gas combustion
products (carbon monoxide and nitrogen oxides), the Company
introduced a Plan for the reduction of gas combustion at the
flaring units of the platforms, OPF, and LNG plant as well as for
the reduction of unplanned shutdowns at the LNG plant. As a result,
the total gross emissions have decreased by 3 percent in
2012.
For the same purpose, gas turbines equipped with devices that help
reduce the emissions of nitrogen oxides, as well as flaring units
with the additional gas supply system to improve its turbulence
(which allows burning gas in sootless mode) are used at the
facilities.
Fuel tanks are equipped with the pipe junctions of the system for
recirculation of fuel vapours from the storage tank to the truck
tank. The effectiveness of reducing the emissions of volatile
hydrocarbons during refuelling has reached 90%.
