Slide 1

FLARE RECOVERY SYSTEMS AND THE "FLARE BULLET" Economic way to deal with flare minimisation Jonathan MILES Argo Environmental Engineering Limited

Slide 2

The Environment CO 2 from Power Generation and Fuel Gas CO 2 from Flaring VOC from tank emanations/transport

Slide 3

Environmental Emissions - UKOOA Flaring rose in UK in 2006 to 1.725 m tons CO 2 outflows in 2006 fell by around 1m tons

Slide 4

UKOOA Commitment 47 UK Flaring in 2001 spoke to around 30% of Industry CO 2 discharges (5.5 m tons) Started Emission Trading Scheme Participants concurred target 10% emanation lessening underneath assent understandings

Slide 5

Best In Class? Examination 2000-2004 has appeared: Best in class produces 0.63 ave kg CO 2/boe Worst in class – 38.61 ave kg Of most noticeably awful 10 entertainers in flaring just 3 had stranded gas supplies with 7 associated with gas gathering frameworks Foinhaven has stranded gas repository yet accomplishes in main 10 CO 2 from Flare/boe 7 of main 10 entertainers were BP worked

Slide 6

The "Passing Zone" on a flare – Turndown to 1-2% Flare and related hardware harm Wasted Gas – particularly if fuel gas lacking – blazing diesel CO 2 or exchanging or assess administration. Notoriety Potential income/cost sparing of $1million every year How does diminished flaring spare cost

Slide 7

What is zero flaring

Slide 8

Flare Gas Recovery HP flare To flare Bursting Disk LO HH PT FOV N supply 2 HH FE XV Check valve HP K.O. Sources Drum Drain

Slide 9

FOV Layout To flare Bursting circle Tie in 2 Manual valve FOV Tie in 1

Slide 10

Fast Opening Valve Mokveld valve has SIL-level 3 (MTBF=2160 years of operation to "full stroke") Tyco valve has SIL-level 3 (MTBF=523 years of operation to "full stroke")

Slide 11

Flare Opening Assemblies Rupture plate/Buckling pin valve Buckling pin valve Bursting circle

Slide 12

Flare Gas Recovery – financial aspects Annual esteem accepting: Quota exchanging Increased gas send out 2 flare change outs Annual income from flare gas recuperation $1,000,000 Typical Installed Cost - $2-4 million (less expensive on new offices) Pay back time will normally be 2-4 years

Slide 13

Low Pressure System

Slide 14

LP start framework: Automatic Pellet Launching cupboard and air propelling jug Guide pipe Pellet gatherer unit (discretionary) Flare Gas Ignition

Slide 15

LP framework ordinary establishment

Slide 16

Long-extend start pellet Armed by the starting weight Ignite when risen up out of guide pipe Independent of developing speed Will not touch off if presented to flame Flare Gas Ignition System

Slide 18

Low weight Ignition System Ekulama II - SPDC Nigeria

Slide 19

Low weight Ignition System Ekulama II - SPDC Nigeria

Slide 20

Flare Gas Ignition No moveable parts or electronic hardware situated close flare tip When required upkeep is performed at cupboard All gear in warmth radiation territories are warmth in safe material High unwavering quality and long lifetime

Slide 21

Conclusions and Recommendations Install FGR if in fact plausible Increased income regularly $1million Cost to introduce $2 – 4 million Install Pellet Ignition framework – suit all frameworks Increased dependability of start Increased security Reduced support Cost approx $150,000
