Flare Gas Recovery
Traditionally, in the Oil & Gas industry, waste and surplus gas
has been disposed of by flaring to atmosphere. Today this process is becoming
increasingly unacceptable as the industry progresses towards eliminating the
emission of greenhouse gases into the atmosphere, whilst simultaneously
conserving energy.
Our Flare Gas Recovery Units are installed in numerous refineries, oil
fields and gas fields worldwide. They can handle flows ranging from 200 to
6.000 m3/h (850 to 26.500 gpm), 1.2 to 30 bar (18 to 450 psi) for
sliding vane based Flare Gas Recovery Units, and from 1.200 to 15.000 m3/h
(5.200 to 66.000 gpm), 1.2 to 4.7 bar (18 to 70 psi) for liquid ring based
Flare Gas Recovery Units
In Petroleum refineries, Natural gas processing plants and
in Oil and gas Production sites, mixture of natural gases is generated from the
below sources:
1.
Extraction
of Natural Gas along with oil from oil wells,
2.
Gases
formed above the liquid level in storage tanks
3.
Flashing
of high pressure crude to low pressures.
This gas consists of a mixture of various hydrocarbons and
is also known as associated petroleum gas.
The Gas is flammable in nature and its composition varies
from plant to plant and will also vary with time over the operating life of the
plant/Oil-well.
Crystaltcs facility’s safety depends on properly
integrating the Flare Gas Recovery
System into the relief header and the flare system.Each gas contaminant and each gas product influence the optimal lineup
of treatment steps, and expertise is required to quickly evaluate these. An
internal study focusing on Iran has shown that approximately 50-70% of the
currently flared gas resources in Iran can actually be made into valuable
products with a payback period.
Need for Flare Gas Recovery:
Flare
Gas being a combination of petroleum gases can be used as a source of Energy.
An industrial survey has indicated that the amount of Gas burned in the Flare
Stacks throughout the world in the year 2011 amounted to almost USD 29.8
billion.
Utilizing
Flare gases helps the plant to cut down on its Energy costs and also create an
in-house Fuel source.
Improper
burning and incomplete burning leads to generation of toxic and harmful gaseous
pollutants. The produced gases are known to create harmful and deadly effects
on human life and the surrounding environment.
The
Flaring of Flare gas is also a considerable source of carbon di-oxide
emissions.
Hence
utilizing flare gases can help an industry to reduce Energy costs, reduce its
Carbon footprint and be responsible to the environment.
Flare Gas
Recovery Systems can following processes:
·
Isolating the flare header with a
proprietary-design liquid seal or staging valve
·
Recovering normally flared gases and
delivering them back into the facility so they can be processed and re-used as
fuel gas
·
Removing liquids
·
Compressing gases up to a defined pressure
level
·
Cooling recovered gases
Our
liquid ring vacuum pumps and compressors are renowned for:
Ø rugged
design construction - making them tolerant to carryover from process upsets
Ø low
maintenance requirements - best up-time in the industry
Ø cool-running
- making them ideal for handling the explosive gases found in refinery
applications, with pressures up to 215 PSIA (14.8 bar)
Ø the largest and most
experienced technical staff in the industry
Ø comprehensive
value-added centers throughout the world.
Crystaltcs has provided complete flare gas recovery compressor systems
that comply with environmental regulations and provide an immediate return on
investment through the reuse of captured flare gas as valuable fuel or
feedstock. With a CrystaltcsFlare Gas Recovery System you can achieve near-zero
flaring and reduce costly emissions while reducing unplanned downtime. Every
system is customized to meet specifications, offering a complete packaged
solution backed by our global network of service and support.
