temperature is 39°C. Gas moisture content gas is 5.36 g/m 3 , the initial potential content of
condensate in the formation gas is 46.77g/m 3 .
Carried out calculations of low-temperature gas separation process shows, that for the
gas treatment of Surgil field in volume 3.0·10 9 m 3 per year with the regulated quality there is
required construction of three identical technological lines of LTS by productivity of each
3.0·10 6 m 3 /day.
During supply of unstrapped gas from the field to one technological line of LTS in
volume 125901 m3/hour, there will be extracting 123384 m3/hour of the stripped and dry
gas and 4322 kg/hour of the stable condensate.
For stable condensate storing it is necessary to provide condensate park on the CGTU
proceeding from volumes of its extraction 311.2 t per day.
It is also necessary to provide a reserve technological line.
CGTU consist of the following constructions (figure 5):
- incoming-line unit;
- low-temperature gas separation plant (with turbo-expander);
- DEG fire regeneration;
- condensate separation and aeration plant;
- assembly of self-supporting gas measuring (with reduction assembly);
- technological pumphouse of condensate;
- DEG warehouse;
- torch separator platform;
- drainage tank for DEG V=25m 3 ;
- drainage tank for condensate V=63m 3 ;
- area for torch farm;
- condensate warehouse;
- compressor house of compressed air;
- condensate loading platform;
- drainage tank of torch farm V=16m 3
