Flare Gas Recovery vs Capital Cost

Business Context

Refineries and production facilities use flare systems to safely dispose of excess hydrocarbons during startups, shutdowns, emergency depressurization, and process upsets. Recovering flare gas reduces emissions, improves hydrocarbon utilization, and supports sustainability objectives. However, flare gas recovery systems require compressors, piping, controls, and additional processing equipment that increase project costs.

The Contradiction

Increasing flare gas recovery improves environmental and operational performance.

However, recovery systems require significant capital investment and additional maintenance.

Why the Contradiction Exists

Flare systems are designed primarily for safety rather than product recovery. Capturing variable gas flows requires flexible equipment capable of operating under widely changing conditions.

Operational Risks

Excessive flaring increases emissions and product losses, while poorly designed recovery systems may compromise flare availability during emergencies.

Oil Industry TRIZ Analysis

Recovery systems should be designed with modular compression, intelligent controls, and dynamic operating strategies that maximize gas recovery without compromising emergency flare performance.
