Vapor Recovery System Gas Station

Gas stations and vapor recovery systems the san diego county air pollution control district apcd regulates emissions from gasoline.

Vapor recovery system gas station.

A system designed to capture displaced vapors that emerge from inside a motorist s fuel tank when gasoline is dispensed into the tank. Since 1980 our jordan technologies division has designed manufactured and serviced vrus across multiple industries including liquid loading terminals o g production and midstream distribution and gasoline stations. Vapor or vapour recovery is the process of collecting the vapors of gasoline and other fuels so that they do not escape into the atmosphere. This is often done and sometimes required by law at filling stations to reduce noxious and potentially explosive fumes and pollution.

Recovery of 0 15 to 0 20 of the delivered gasoline volume is normal. Stage ii vapor recovery equipment controls vapors which would normally be. Gasoline vapor losses can vary widely depending on local weather conditions frequency of gasoline deliveries and the volume of gasoline being sold at the station. When a conventional nozzle is used the displaced vapors flow out.

Most gas stations are equipped with an in station diagnostic isd system which monitors ust pressure and set alarms when the recorded pressures exceed a specified criteria. The opw vaporsaver stage ii vapor recovery system from opw fueling components uses membrane technology to separate gasoline vapors into fuel and clean air. Historically connecticut maine massachusetts new hampshire rhode island and vermont had regulations that require stage ii vapor recovery at certain gasoline stations depending on the amount of gasoline pumped at the facility and the facility s location. When the tanks are filled the rising liquid forces these vapors to seek an escape route.

A typical payback of 3 to 5 years is expected for larger volume gas stations. The isd pressure monitoring is intended to limit emissions from fugitive leaks and vent line emissions that would compromise the control efficiency of the phase ii vapor recovery system. Gasoline vapors accumulate in automobile and truck tanks above the liquid level. Tehran head of the national iranian oil products distribution company niopdc has announced the implementation of the first phase of a plan called kahab for recovery of gasoline vapor in the country s gas stations shana reported.

The gasoline dispensing rules require vapor tight recovery systems to prevent vapor loss when transferring gasoline between the bulk storage facility and the delivery vessel tanker truck and between the delivery vessel and the storage tank at the gas station.
