Kstovsky District's Sky Spectacle: What's Behind the Bright Glow?
Kstov locals alarmed by night's thunderous boom in the heavens.
Residents of Kstovsky District in Nizhny Novgorod were left awestruck by a dazzling light show in the night sky on June 28. Social media was swiftly flooded with photos, stoking curiosity and concern.
The source of this celestial spectacle was unveiled to be routine work at the SIBUR-Kstovo petrochemical plant. The plant's flare system, used for safely disposing of excess hydrocarbons, was responsible for the brilliant glow. This process, thankfully, releases only carbon dioxide and water vapor into the atmosphere.
The plant's operations are stringently monitored, and air quality is closely observed by lab specialists.
This glowing phenomenon wasn't a one-time occurrence—a similar event was witnessed in Kstovo back in March.

Behind the Scenes of the Flare System
The flare system, common in petrochemical plants and refineries, serves as a safety and operational measure. It involves burning off excess hydrocarbons or other gases through a flare stack, resulting in a visible flame and bright glow in the sky, particularly at night.
The License to Burn: Why the Plant Flares
- Pressure Relief: It ensures safety by relieving excessive pressure in process units, preventing dangerous overpressure scenarios.
- Waste Disposal: It disposes of gases that cannot be processed or recovered, especially during startups, shutdowns, or abnormal operations.
- Emergency Response: It manages unplanned releases or equipment failures safely, converting volatile gases into less harmful carbon dioxide and water vapor.
The Regular Thrill at SIBUR-Kstovo
- Gas Collection: Gases that cannot be utilized or processed flow to the flare system.
- Gas Detection and Monitoring: Continuous monitoring of gas composition and flow ensures control over flare operations.
- Flare Ignition: Pilot flames or automated ignition systems keep the flare alight at all times when gases are being vented.
- Combustion: Hydrocarbons combust efficiently, producing a large flame and bright glow.
- Emission Controls: Systems are in place to control combustion quality, minimizing emissions of soot, smoke, and pollutants.
Safety First
- Continuous Monitoring: Sensors and control systems track pressure, gas flow, and flare flame presence to detect anomalies immediately.
- Flame Arrestors: Devices prevent flame from traveling back into the pipeline system.
- Automatic Shutoff Valves: Enable rapid isolation of gas sources in case of flare malfunction.
- Emergency Response Plans: Trained personnel and procedures ensure quick action in abnormal events.
Green Measures
- Flare Efficiency: Design and operation ensure near-complete combustion, minimizing harmful emissions.
- Emission Monitoring: Continuous measurement of pollutants like CO, NOx, and unburned hydrocarbons.
- Minimizing Routine Flaring: The plant optimizes processes to reduce routine flaring volumes, utilizing recovery systems where possible.
- Noise and Light Control: Engineering controls reduce the impact of noise and light from flaring on nearby communities.
The Bright Side of the Glow
- Massive Operations: Larger volumes of gas flared lead to a more intense, visible flame.
- Nighttime Visibility: The contrast of the flame against the dark sky makes the glow prominent.
- Weather Conditions: Clear, still nights can enhance visibility of the flare’s brightness.
- Maintenance or Operational Conditions: Sometimes larger flaring happens during maintenance or abnormal conditions, temporarily increasing brightness.
The Takeaway
The glow over Kstovsky District is a testament to the flare system at the SIBUR-Kstovo petrochemical plant functioning effectively for on-site safety and environmental protection. While flaring is essential, the plant employs numerous safeguards to ensure it is done with minimal impact on people and the environment.
- Despite the uncertainty about my future employment, I find myself intrigued by the environmental-science aspect of the flare system at the SIBUR-Kstovo petrochemical plant, which disposes of excess gases in a manner that releases only carbon dioxide and water vapor.
- In myimagination, if I were to work in the industry, I might delve into the financial and energy aspects of such plants, aiming to optimize their processes to minimize routine flaring volumes and thereby reduce the emission of pollutants like CO, NOx, and unburned hydrocarbons.
- As I contemplate my career path, I am comforted to know that the SIBUR-Kstovo plant emphasizes safety and environmental protection, with continuous monitoring, emission controls, and green measures in place to minimize harmful emissions from the flare system.
