Definition:
A system that captures and repurposes gas that vaporizes from condensate or crude oil storage tanks, reducing emissions and improving efficiency.
Key Components:
- Flash Separator: Separates lighter hydrocarbons from condensate.
- Compression & Processing: Conditions gas for reuse or sale.
- Storage Tank Management: Ensures controlled vapor capture and handling.
Use Cases/Industries:
- Upstream Oil & Gas: Reduces venting losses from crude oil production.
- Refineries: Recovers light hydrocarbons from storage tanks.
- Environmental Compliance: Meets regulations for volatile organic compound (VOC) emissions.
Advantages:
- Emission Reduction: Prevents methane and VOC release.
- Energy Efficiency: Converts wasted gas into usable fuel.
- Economic Benefit: Recaptures hydrocarbons for resale or onsite power.
Challenges:
- Infrastructure Needs: Requires dedicated gas capture systems.
- Fluctuating Volumes: Flash gas rates vary with temperature and pressure.
- Regulatory Compliance: Needs monitoring to meet environmental laws.
Related Terms:
Vapor Recovery Unit (VRU), Methane Capture, Hydrocarbon Recovery
Example:
A refinery installs a flash gas recovery unit to capture light hydrocarbons from crude oil storage tanks and reuse them as process fuel.
