What Are Rotary Sliding Vane Compressors
A vapor recovery compressor is a specially designed compressor used for handling wet, heavy , or acidic gases. Its main purpose is to recover vapor that would otherwise be released into the air, mitigating air pollution. The captured vapor is then cleaned, separating the liquids from the gases. Rotary sliding vane compressors are the best type of compressor for this application, as they can easily handle these tough and varying gases and have the ability to run 24 hours a day, seven days a week, requiring very little maintenance.
Key Takeaways to Review
- Emission Reduction: VRCs significantly reduce VOC emissions. This contributes to cleaner air and maintains compliance with environmental regulations.
- Cost Efficiency: Recovered vapors can be reinjected into the production process or sold, transforming potential waste into revenue.
- Enhanced Safety: By containing and processing vapors, VRCs reduce the risk of fire hazards that are associated with flaring or venting.
- Operational Reliability: Designed for continuous operation, VRCs ensure consistent performance with minimal maintenance.
How Vapor Recovery Compressors Work
Vapor recovery compressors operate by collecting vapors from storage tanks or pipelines and compressing them to a higher pressure. This process involves several stages:
- Vapor Collection: Vapors are drawn from storage tanks or pipelines where pressure changes or temperature fluctuations cause the release of gases.
- Compression: The collected vapors are compressed, increasing their pressure and preparing them for further processing.
- Condensation: The compressed vapors are cooled, causing the hydrocarbons to condense into liquid form.
- Separation: The liquid hydrocarbons are separated from the gas, allowing for the recovery of valuable liquids and the purification of the remaining gas.
This process not only captures valuable resources but also reduces emissions, aligning with environmental sustainability goals.
Applications in the Oil & Gas Industry
Vapor recovery compressors are commonly utilized in the oil and gas industry for applications such as:
- Oil Storage Tanks: Capturing vapors released during the storage of crude oil.
- Pipeline Operations: Recovering vapors from pipelines during maintenance or pressure changes.
- Processing Facilities: Collecting and processing vapors from refining and chemical processes.
These applications help reduce emissions, improve safety, and enhance operational efficiency.
Benefits of Vapor Recovery Compressors
Emission Reduction
By capturing and compressing vapors, vapor recovery compressors significantly reduce the emission of VOCs and other pollutants into the atmosphere, therefore contributing to cleaner air quality and helping companies comply with environmental regulations.
Cost Efficiency
The recovered vapors can be reinjected into the production process or sold, converting what would be waste into valuable resources. This not only generates additional revenue but also reduces the need for purchasing external fuel sources.
Enhanced Safety
By preventing the release of flammable vapors into the atmosphere, vapor recovery compressors reduce the risk of fire hazards associated with flaring or venting. This enhances operational safety and protects personnel and equipment.
Operational Reliability
Designed for continuous operation, vapor recovery compressors ensure consistent performance with minimal maintenance. Their robust design and high efficiency contribute to the reliability of industrial operations.
FAQs
What is a vapor recovery compressor?

Invest in Vapor Recovery Technology
Rotary screw and reciprocating compressors can be used for vapor recovery, but rotary sliding vane compressors are the best solutions. Their ability to handle varying gas compositions and varying gas flows is unmatched by the others. Sliding vane compressors only require a small amount of oil for lubrication and protection of the compressor internals; they require little maintenance and much of the maintenance and repair work can be done onsite in a short amount of time using just three tools.
