Vapour Recovery Systems
is the process of recovering the vapour of gasoline or other fuels so that they
do not escape into the atmosphere. This is often done (or required by law) at
filling stations, in order to reduce noxious and potentially explosive an
amount of gas and pollution.
Vapour recovery units are also becoming commonly used in the
oil and gas industry as a means of recovering natural gas Vapour and making it
a usable and profitable product. Specifically, a newer form of Vapour recovery
technology, Ejector Vapour Recovery Systems Units
create a closed-loop system which not only recovers valuable vapour but also
reduces methane and Volatile organic compound (VOC) emissions. Generated
Vapours in most applications come under the category of Volatile Organic Compounds
(VOC). Some of these compounds are known to affect air quality and create Air
pollution and are classified as Hazardous Air Pollutants (HAP). Vapour Recovery Systems
are also used in the oil and gas industry to provide flash gas recovery at near
atmospheric pressure without the potential of oxygen ingress from the top of
the storage tanks
Vapour Recovery Unit
(VRU)
A Vapour Recovery Unit (VRU) is a set-up designed to remove
unwanted vapours present in crude oil or distillate tanks allowing operators to
comply with prevailing emission regulations. VRU systems can be employed in a
wide range of chemical industries with several variants available. For example,
a Vapour Recovery System for storage
tanks can be used to recover vent gas from crude oil and distillate tanks at
storage facilities.
Ejectors in Vapour
Recovery Systems:
·
Ejector vapour recovery systems operate in the
form of a closed-loop system.
·
They suck the vapours and discharge them into
the Intermediate stages of the Gas compressors. The Gas compressors further
compress the vapour mixture and discharge to the gas supply lines.
·
The high-pressure gas stream from the Gas
Compressor is used as an energy source by the Ejectors in Vapour Recovery Systems.
·
As the high-pressure gas passes through the ejector
it expands and forms a low-pressure region which sucks the vapours.
·
The vapours mix with the motive gas and mixture
is then compressed up to discharge pressure.
·
A recycle line is used between Ejector Discharge
and Suction points to control the suction pressure.
In the Oil and Gas Industry, product vapours are produced by the following processes:
·
Flashing from High Pressures to Low Pressures
·
Gas-Liquid Separation in Separators
·
Evaporation from Storage tanks
