Enhanced Vapor Recovery Systems
Air Liquide, the world leader in the development and supply of gases engineered to help protect our environment, provides the calibration gas mixtures, pure gases and gas handling equipment needed to accurately and safely test hydrocarbon sensors and vapor polishing systems used in enhanced gasoline vapor recovery systems.
Hydrocarbon Sensor Verification Program for Gasoline
The California Air Resources Board mandates periodic testing of the hydrocarbon sensors used in enhanced gasoline vapor recovery systems. The sensor must be tested at three different concentration ranges with propane being the surrogate hydrocarbon for this testing.

Recommended Equipment
Scott Brand Model 205 Single-Stage Gas Pressure Regulator
SCOTTY Model 27 Single-Stage Gas Pressure Regulator (fixed flowrate of 1 ppm)
Scott Brand Model 30 Flowmeter
Testing Vapor Polishing Systems for Gasoline
The California Air Resources Board mandates periodic testing of the vapor polishing system for gasoline. The efficiency of the activated carbon adsorbers must be evaluated annually using isobutane as the surrogate hydrocarbon.
