As it is obvious, additional introduce during operation of Surgil field will make about
1941.936t/year of pollutants of 7 names. Thus, capital contribution brought by nitrogen
oxides (60.3965 %) extracted during torch operation.
Emissions during operation of pond-evaporator, drainage tank, condensate loading
post have insignificant character (no more than 1t/year in total). More detailed characteristic
of these emissions will be given on the following design stage after specification of initial
data.
Except constant ingress of pollutants in atmosphere during object functioning, it is
possible periodic and short-term ingress of gas combustion materials during repair and
purging works on CGTU. Also, there will periodically ingress in atmosphere the gas
combustion materials during purging, repair and research of production wells. More detailed
description of emissions during above-listed operations will be given on the following
design stage.
Atmosphere pollution by the above-stated sources will have constant character.
