4. COAL BED METHANE(CBM):-
➢ CBM IS A UNCONVENTIONAL FORM OF NATURAL GAS FOUND
IN COAL DEPOSITS OR COAL SEAM
➢ IT IS A PRIMARY CLEAN ENERGY SOURCE OF NATURAL GAS
➢ DEVELOPMENT AND UTILIZATION OF CBM IS GREAT SOCIAL
AND ECONOMIC BENEFIT & ENVIRONMENTAL BENEFIT
➢ CBM PROCESS CAN BE EXPLAINED INTO THREE TYPES

6. COAL BED DRILLING COAL BED PRODUCTION COAL BED PRODUCTION
➢ CBM IS A FORM OF
NATURAL GAS THAT
IS PRODUCED BY
DRILLING.
➢ CBM IS EXTRACTED
BY PUMPING OUT
THE WATER, WHICH
LOWERS THE
PRESSURE,
ALLOWING THE GAS
TO DETACH FROM
THE COAL SURFACE
AND FLOW OUT IN
TO THE WELL.
➢ PRODUCED BY
PUMPING AND
REMOVING WATER
TO REDUCE
HYDROSTATIC
PRESSURE IN
SUBSTANCE SO THAT
METHANE CAN
DESORB FROM COAL
BEFORE METHANE
EXTRACTION CAN
BEGIN .
➢ CBM PRODUCED AT
CLOSE ATMOSPHERIC
PRESSURE

8. MAIN COMPRESSOR STATION(MCS):-
➢ SLC SYSTEM IS USED IN MCS
➢ SINGLE LOOP CONTROL SYSTEM (SLC)
➢ REGULATES THE GGS AND DETECTS THE DANGER
➢ WE CAN SEE THE WORKING VALUES OF EQUIPMENTS

➢ GGS 01 WORKS ON SAME PROCESS AS MCS ONLY A FEW CHANGES ARE
THERE
➢ GGS 01 HAS LPC(LOW PRESSURE COMPRESSOR) 0.5-14 KG/CM2 WHERE
MCS HAS LPC MC & HPC
➢ GGS 01 HAVE DRYER
➢ GGS 01 SUPPLY GAS TO MCS
➢ GGS 01 – TWO(2) STAGE DOUBLE ACTING RECIPROCATING

19. FLARE SYSTEM:
FLARES ARE IMPORTANT SAFETY DEVICES. THEY ARE USED THROUGHOUT THE
INDUSTRY AS A SAFETY MECHANISM TO ENSURE PROCESS UNITS DO NOT
EXCEED SAFETY LIMITS. THE USE OF FLARE IS UNLIMITED WHEREVER POSSIBLE.
HOWEVER FLASHING CAN OCCUR DURING UNPLANNED
OPERATIONAL INTERRUPTIONS, SCHEDULED DOWNTIME, AND SOMETIMES
DURING A STARTUP AND SHUTDOWN. GASES ARE COMBINED WITH STEAM AND
BURNED OFF

20. TO ENSURE MAXIMUM COMBUSTION AND MINIMIZE EMISSIONS. A FLARE IS USUALLY 20 - 150
METERS ABOVE THE GROUND. IT PREVENTS ANY POTENTIAL FOR THE HEAT GENERATED TO
AFFECT THE SURROUNDING EQUIPMENT OR PEOPLE WITHIN ITS ROUTINE.
FLARE FRONT GENERATE SYSTEM(FFG)
THE MOST WIDELY USED FLARE PILOT IGNITION SYSTEM IS THE COMPRESSED AIR
FLAME FRONT GENERATOR. WITH THIS SYSTEM COMPRESSED AIR AND FUEL GAS
ARE METERED THROUGH CONTROL VALVES IN TO A MIXING CHAMBER LOCATED AT
GRADE. DOWNSTREAM OF THE MIXING CHAMBER THERE IS A A SPARKING DEVICE
TO INITIATE THE FLAME FRONT(FIREBALL). DURING OPERATION THE FLOW OF FUEL
GAS IS ESTABLISHED THROUGH THE SYSTEM AND THE FLAME FRONT IS FIRST
PURGED, AND THEN FILLED WITH THE GAS/AIR MIX. THE MIX IN THE COMBUSTION
CHAMBER IS IGNITED AND THE FLAME FRONT IS INITIATED. THE FLAME FRONT
“FIREBALL”TRAVELS TO THE PILOT TIP WHERE IT IGNITES THE PILOT. WE CAN
IMPROVE PROCESSES AND TECHNOLOGY TO REDUCE THE AMOUNT OF FLARE
MATERIAL THROUGH IMPROVED RECOVERY AND REPROCESSING OF EXCESS
MATERIALS.
