State-of-the-art separation of associated petroleum gas (APG) and raw natural gas into high-purity commercial petrochemical feedstocks through advanced cryogenic fractionalization and amine treating technologies.
ООО "АВТОДОРТРЕЙД-БТК" operates one of the most advanced Gas Processing Plants (GPP) in the region. Our facility transforms hazardous byproducts into highly lucrative commercial commodities through precision engineering and world-class separation technologies.
Temperatures below -120°C condense ethane, propane, and butane from methane stream using turbo-expander technology for maximum NGL recovery.
Aqueous MDEA solutions strip H2S and CO2 yielding safe, sweet natural gas meeting international pipeline specifications for export.
Molecular sieve beds remove water vapor to prevent hydrate formation and corrosion in downstream pipeline infrastructure.
Claus process converts removed H2S into elemental sulfur (99.9% purity) for fertilizer and chemical industry applications.
Raw gas enters through high-pressure separators removing free liquids, solids, and condensates before processing begins.
Amine contactors strip hydrogen sulfide and carbon dioxide to meet pipeline quality standards and environmental regulations.
Gas is chilled to -120°C using propane pre-cooling and turbo-expander refrigeration for NGL condensation.
De-ethanizer, de-propanizer, and de-butanolizer columns separate NGLs into specification-grade ethane, propane, and butane products.

Processed gas products are distributed through integrated logistics networks ensuring reliable delivery to domestic and international markets.
Sweet natural gas enters the unified gas supply system for distribution to power plants, industrial consumers, and municipal utilities across the region.
Propane and butane are loaded into ISO-certified pressurized railcars for delivery to regional markets and export terminals with just-in-time scheduling.
High-purity ethane, propane, and butane are exported via specialized LPG carriers to petrochemical facilities in Asia-Pacific and European markets.
All gas processing operations adhere to Russian Federal Law 116-FZ "On Industrial Safety", GOST technical standards, and international environmental frameworks with third-party verification.
Zero LTI record maintained across all gas processing facilities for 450+ consecutive days. HSE protocols aligned with IOGP guidelines and regular third-party safety audits.
Full EIA documentation for all projects; sulfur recovery efficiency >99.9%; flare gas minimization program; carbon intensity reporting aligned with TCFD framework.
All processing, measurement, and quality control performed per GOST 31371 series, ISO 6976, and ASTM D1945 with independent laboratory verification.
ООО "АВТОДОРТРЕЙД-БТК" offers flexible offtake agreements for ethane, propane, butane, and sulfur products. Contact our commercial team to discuss your feedstock requirements.
