At the Main Transfer Pumping Station (MTPS) of West-Mogutlor oil field (OJSC Aganneftegasgeologia), the associated gas treatment system supplied by the ENERGAS Company will operate. It is a multifunctional process complex, it includes the following equipment:

• booster compressor unit of screw type;
• adsorption gas dryer;
• gas cooling unit (chiller);
• gas metering station with flow meters.

All equipment is installed at a single site, is placed in separate all-weather enclosures and designed for operating in automatic mode.



ENERGAS experts developed this project on the basis of special engineering solutions, allowing to achieve negative dew point temperature of water (-20°C) while APG compression. Another feature is that dehydration of associated gas is carried out by two methods: refrigeration and adsorption.

APG treatment system will sequentially perform the following process tasks:

1. Dehydration – separating fractions from source associated gas which can dropout as condensate when temperature changes during the subsequent compression.
2. APG second-stage treatment at gas inlet to the compressor unit. It is implemented by high efficiency separator – inlet filter-scrubber.
3. Compression – increase of gas pressure to the projected level of 3 MPa required for injection of APG into the transport pipeline.
4. Metering of treated gas volume.
5. Cooling of associated gas up to the stable parameters, specified by design requirements.

Currently at the facility, there is prepared a booster compressor unit for the operation. Designed pressure of associated gas at BCU inlet is 0.25 MPa. Performance is 850 m3 / h.



At the same time engineers of the LLC ServicENERGAS (companies group ENERGAS) performs start-up and adjustment works on gas dryer and gas cooling units.
