- route inspections and surveys;
- experiments for approbation of nature-conservative measures and means of
engineering protection.
Gathering, storage and processing of results of all data types is carried out in a
uniform universal databank, organized by PEM service.
For regular air sampling in the territory and at the border of the nearest settlements
there can be organized route posts of the air monitoring. Monitoring is possible by means of
two mobile moving laboratories on the Gas-66 PLM-F base.
The main components are included necessarily controlled substances: sulfur dioxide,
mercaptans, nitrogen oxides, carbon oxide, and methane.
Monitoring periodicity is established subject to danger class of harmful substance
and as follows:
- for I class - not rare than 1 time in 10 days;
- for II class - not rare than 1 time a month;
- for III, IV classes - not rare than 1 time a quarter.
Monitoring of sources of pollutants emissions on the new industrial areas should be
made by forces of laboratory of environmental protection.
Atmospheric air
With a view of protection of air basin it is necessary to provide following actions:
- all production equipment, accessories, gas- and condensate lines, liquefied gas
pipelines should be reliably encapsulated.
- gas discharging through safety valves and aeration gases should be obligatory burnt
on the torches;
- torch height should provide permissible concentrations in air of the working area of
products of gas combustion products.
There is basically provided application of valves with joining “under welding” for
maintenance of the maximum air-tightness and minimization of leaks in environment.
Valves included into ADP (anti-damage protection) system has operation time no
more than 12 seconds
All control valves should be flanged for possibility of carrying out of valves check.
There is provided protection of the equipment by system of the safety valves
consisting of service and reserve valves, irrespective of terms of safety valves check.
For maintenance of trouble-free operation of technological installations the project
provides:
hermetic sealing of the equipment and pipelines;
