WHY INSTALL A FLARE GAS RECOVERY SYSTEM?
Envirocomb Limited
THE ENVIRONMENT Removal of three types of pollution:
•Atmospheric (smoke, SO2, NOx, etc.) •Light •Noise
NB: In many parts of the world continuous flaring is not permitted.
Envirocomb Limited
THE ECONOMIC ARGUMENT Consider a typical plant with continuous flaring of 1 ton/h:
Value of flared gas: 8000 x 1 x $150 = US$ 1,200,000 per year First Year Operational Costs (Electricity & Water): = US$ 150,000 (approx) Total installed cost of flare gas recovery system: = US$ 700,000 (approx)
Payback achieved in 8.5 months! Subsequent yearly operational savings = US$ 1.050,000! For larger systems the payback is shortened!

THE COMPRESSOR
Envirocomb Limited
TYPES OF COMPRESSOR Generally three types of compressor have been used for flare gas recovery systems:
Reciprocating, screw and liquid ring
Reciprocating and screw type compressors are more efficient but they are also more expensive, require more maintenance and downtime, result in compressed gases being at high temperature and are not tolerant to condensates being present in the gas.
For flare gas recovery liquid ring compressors have many advantages.
Envirocomb Limited
ADVANTAGES OF LIQUID RING COMPRESSORS Liquid ring compressors are generally the best to use for flare gas recovery systems for the following reasons: •Able to handle gases containing condensates •Able to handle gases containing particulates •Able to handle wet gases •Able to handle toxic, flammable and corrosive gases •Works without lubricants •Gas temperature rise is low - 10OC •Because of liquid ring, compressors are inherently safe •System tolerates sudden gas and condensate surges

THE GARO DESIGN
Envirocomb Limited
GARO is the preferred supplier of liquid ring compressors due to many technical advantages. Double lobe casing to balance radial pressures acting on overhung impeller with a single mechanical seal. • • • •
Envirocomb Limited
Noise is dictated by the electric motor Reduced vibration levels give bearings a longer life Potential leakage point with atmosphere reduced to one mechanical seal The mechanical seal is the only component subject to wear and is easily replaced.
FRONT PULL OUT •
Fast access to compressor internals without putting the machine in vertical position.
DISTRIBUTION CONE
• Lower power consumption

Envirocomb Limited
The GARO machines are custom engineered to meet process requirements. Dimensional changes to internal components alter the machine’s operational capability. Each size of compressor can be adjusted to vary pressures, flow rates and power consumption within a range. This optimizes performance in relation to the required conditions of service. Post supply process changes can often be accommodated without the need to replace the machine.
