PFS “Surgil field complex costruction with valuable
components retrieval”
2.7 GAS AND CONDENSATE TRANSPORT
In the performance specification for development PFS “Surgil field complex
construction with valuable components retrieval”, in Section II “Gas and chemical complex
construction” there is provided GCC location by one of the variants, in the Akchalak
settlement area of Kungrad region. This variant is optimum (figure 7).
Treated and dry gas in volume 3.0·10 9 m 3 per year and a stable condensate in volume
140·10 3 t per year from Surgil CGTU turned for processing to GCC, located in the area of
Akchalak settlement.
Preliminary hydraulic calculation of gas pipeline Surgil CGTU -Akchalak GCC is
executed for productivity 9.09·10 6 m3/day. Gas pressure and temperature in the beginning
of gas pipeline make 5.5MPa and 39 0 С relatively. Gas pipeline length is 115.0km.
According to results of hydraulic calculation, if the diameter of gas pipeline is
820х19mm, so gas pressure and temperature on input Akchalak GCC will make 4.7MPa
and 25.9 0 С.
Condensate line length is 115.0km. Condensate pressure and temperature in the
beginning of condensate line make 1.6MPa and 25 0 С relatively. According to results of
preliminary hydraulic calculation, if the diameter of condensate line is 219х11mm, so the
condensate pressure and temperature on input Akchalak GCC will make 1.2MPa and 25 0 С.
