Introduction to Gasoline Vapor Recovery(Air Quality Protection and Noise Control Division)

A. Air Pollutions from Gas Stations

Most gas stations are located at crowded urban areas, neighboring residential and commercial buildings. Therefore, the issue of gasoline vapor dispersion is highly concerned by citizens.
Introduction to Gasoline vapor Recovery

The volatile organic compounds emitted from the gas stations  are over 420 tons per year, more than 35% of total emission.

Major components and hazard of the air pollutants
→Benzene, toluene, xylene, ethylbenzene, and other hydrocarbons
→Adverse effects to human health
→Ozone pollution to the environment

B. The Sources of Gasoline Vapor Dispersion in Gas Stations

Gasoline vapor dispersion in a gas station are easily caused by:
→Unloading process of oil tankers
→Refueling process of cars and scooters

Embryonic lesion, liver and kidney failure

Ethylbenzene

Sister chromatid exchange, testicular degeneration

Lung and central nervous lesion,

Xylene

D. Control and Status for Gas Stations

Control Measures of Gasoline Vapor Recovery in Gas Stations are enforced by Environmental Protection Administration
→Subsidize gas stations to install gasoline vapor recovery equipment on refueling guns.
    ●From 03/1997 to 07/2000, we subsidize 1/3 to 2/3 of the installation cost of gasoline vapor recovery equipment on refueling guns at gas stations.
●The latest subsidy measure was promulgated on 07/24/2002. For existing gas stations that obtained construction permit before 02/28/2002, we encourage them to install vacuum-assist gasoline vapor recovery equipment on refueling guns.
Promulgating Gasoline Vapor Recovery Equipment Standard for New Gas Stations
●We Promulgated “Gasoline Vapor Recovery Facility Standard for New Gas Stations” on 02/27/2002. New gas stations are required to install gasoline vapor recovery equipment and to maintain them periodically.
Promulgating Management Regulations for Gasoline Vapor Recovery Equipment in Gas Stations
●We Promulgated “Gas Station Gasoline Vapor Recovery Facility Management Regulations” on 09/13/2005. Both new and existing gas stations are required to install gasoline vapor recovery facility and to maintain them periodically.

F. 5 Do’s and 5 Don’ts in Refueling

5  Don’ts

5  Do’s

1. Don’t force refueling

1. Stop refueling

2. Don’t turn on the refueling switch with the gun

2. Turn on the refueling switch with your hand.

3. Don’t knock or drop the gun

3. Protect the gun from crashing

4. Don’t leave oil drops remained in the gun.

4. Let oil drops flow back to customer’s oil tank.

5. Don’t press the gun body

5. Constantly keep the gun and tube clean

- clean the gun handle once per week

- Wax the tube once per month
