Atmospheric Air Protection
Print version
The Company attains reduction of emissions of harmful substances into the atmospheric air through implementation of the following activities:
- incorporation of vapor recovery units (VRUs) into the tank farm equipment for recovery of light hydrocarbon fractions;
- ensuring the tightness of the existing equipment of formation pressure maintenance, crude oil gathering, crude oil treatment and oil transportation systems;
- optimization of the technological process and change of the interfield flows;
- stripping of hydrogen sulfide from associated gas as well as disposal of acid gases;
- transfer of the technological transport involved in oil production to operate on gaseous fuel.
The Company implements the program for optimization and reconstruction of the oil and gas collecting systems. 26 km of gas pipelines were replaced 51 km of gas pipelines were tested in 2008.
At the moment there are 43 hydrocarbon vapor recovery units (VRU) operating at the facilities of the Company. The volume of hydrocarbon vapors recovered by VRUs at OAO TATNEFT tank farms in 2008 amounted to 63 thousand tons.
In total, the Company's gross emissions of polluting matters into the air during the last 20 years were reduced by 3.2 times.
In order to reduce emissions from moving sources gas cylinder equipment was mounted in the reported period at 314 vehicles of motor transport operating in OAO TATNEFT.
Air control in settlements located in the area of the Company's activity is maintained according to the approved schedule. 9,079 analyses of air samples were made in 129 settlements for concentration of different chemicals in 2008,. No excessive concentration was detected.
484 million rubles was spent for air protection in the reported year.
