Structure APG

Structure associated petroleum gas

Associated petroleum gas - the hydrocarbonic gas being in oil pools in the dissolved condition and allocated from oil at pressure decrease.
The quantity of gases in the cubic metre, having on 1 ton extracted oil, depends on conditions of formation and bedding oil deposits and can be from 1-2 to several thousands cub.m

Associated petroleum gas represents mixture of gases. The basic components of APG are saturated hydrocarbons - homologous compound of methane from СН4 to С6Н14. The total maintenance of hexane (C6H14) and heavier hydrocarbons in associated petroleum gas, as a rule, does not exceed 1 %, the maintenance of pentane (C5H12) are in limits of 2 %.

At technological losses and burning of APG  in atmosphere thrown out carbon dioxide and active colloidal carbon. As a result of gas burning in torches in Russia is annually formed almost 100 million tons of emissions СО2 (under condition of effective burning of all volume of gas). However the russian torches are known for the inefficiency, i.e. gas in them is burnt not completely. Accordingly, in atmosphere is allocated methane, much more active hotbed gas, than carbonic gas. Volume of emissions of colloidal carbon at burning APG is estimated approximately in 0,5 million tons per year.
