INDIA Scenario : OPPORTUNITIESA. India has huge Coal Reserves• Total Coal Reserve in India : 319 bn MT , upto 1200 mm depth
( Min. of Coal website, as on 01.04.18)
• Proven : 148 bn MT, Indicated : 139 bn MT, Inferred : 31 bn MT
• Coking Coal : 34.5 bn MT, Non – Coking Coal : 283 bn MT
B. Coal Production is very low B. Coal Production is very low • Actual Coal Production, 2016 -17 : 0.72 bn MT
• Target Coal Production, 2019 – 20 : 1.00 bn MT
C. India imports Chemicals + Petrochems worth US$ 45 bn / yr.
50% of these chemicals can be produced thru CG + CTL route
and can save US$ 21 Bn / yr
INDIA Scenario : Coal/Petcoke Gasfcn Projects
• JSPL, Angul, Odhisha - 7 Lurgi / AL FBDB Coal Gasifiers to make DRI ( Steel ) & Fuel gas
• RIL, Jamnagar, Gujarat - 10 ( 4+6 ) CBI / Mcdermott e-Gas type Entrained Bed type Petcoke ( + Coal ) Gasifiers to meet Refinery H2 demand , Power ( later SNG, Chemicals ) later SNG, Chemicals )

• CIL, Dankuni, West Bengal - probably Entrained Bed Coal Gasifiers to make Methanol & SNG
COAL GASIFICATION : HUGE CHALLENGES IN INDIA
A. Coal related :
• Poor quality of non-coking Coal - high Ash, low Fixed Carbon , low Rank, weathered / deactivated coal
• Large quantity of Coal Fines in Feedstock ( problem in Fixed Bed Gasifiers )
• Problems of reutilization & monetization of Coal Fines• Problems of reutilization & monetization of Coal Fines
• Long distance between Coal source and Plant location - high Freights, more fines, deactivation
• Major variation in quality of feedstock Coal between Mines
• Non-availibility of Dedicated Coal Mines suitable for Coal Gasification
• Inadequate number and capacity of Coal Washing & Blending Facilities
• High price of Domestic & Imported Coal at Factory gate
COAL GASIFICATION : CHALLENGES IN INDIA
B. Environment related :
• Large quantities of Waste / Black water generation
• Costly WW Treatment Plants to meet PCB Norms for ‘Zero Discharge’ & reuse ( Primary, Secondary, Tertiary treatments )
Costly systems for CO2, H2S removal ( Rectisol Gas cleaning & SRU ) & • Costly systems for CO2, H2S removal ( Rectisol – Gas cleaning & SRU ) & Dust Emissions control
• Large area requirement & transportation for huge quantities of Ash storage & disposal / reuse
• CO2 Capture Systems and Applications ( Piping Network, Sequestration, EOR ) not yet fully developed in India
• Increasing global focus for compliance to Climate Change Norms
COAL GASIFICATION : CHALLENGES IN INDIA
C. Technology & Project related :
• Major issue of getting suitable & proven Technology for Indian poor quality Coal
• Coal Feed preparation is very critical, complex & costly , but absolutely essential for success of Gasification technologies and sustainable operation essential for success of Gasification technologies and sustainable operation of such plants
• Frequent change-over of Technology ownership at Global level causes uncertainty
• Very high Project Capex and high Coal price significantly affects Syngas & downstream products costs & overall Project viability
• Hardly any Incentives on Coal price , Products prices , Interest on LT / ST loans, Cess / Duties on Coal, etc. for viability of such Coal Gasification / CTL Projects, so critical for a country like India
COAL GASIFICATION – CHALLENGES IN INDIA
C. Technology & Project related ( contd.) :
• Large Land mass required for Coal storage, handling, sizing, Blending, long distance conveyers, Ash handling, storage, etc.
• Huge quantity of Water resources should be available nearby
• Costly large capacity Cryogenic ASU plants required for Oxygen gas supply
• Sizeable Utilities & Offsites facilities reqd.facilities reqd.
• Inexperienced Vendors vis-à-vis fabrication of critical Equipment ( mainly Gasifiers & its associated parts / equpts ) – to be imported
• Very costly Spares, still have to keep high Inventories
• Experienced EPC / LSTK Contractors not many for Gasification plants
• Experienced O&M Manpower not readily available
• Costly Laboratory Analytical equipment & trained Manpower are required
• No Single Product Plant is viable due to Market demand / price fluctuations - only Polygeneration route configuration is Viable
SUCCESS OF CG / CTL PROJECTS : KEY FACTORS
A. A “National Policy for Coal Gasification & Liquefaction“ needs to be urgently formulated & promulgated to give a ‘big push’ to CG / CTL Projects
B. ‘Dedicated, closeby Coal Mines’ to be earmarked for CG / CTL Projects ( to be bought thru Auction Linkage ) for better Coal Size & Quality consistency, closer Mining cost control & shorter Transportation
C. Financial Incentives by Govt needed to reduce burden of very high Capex of CG / CTL Projects C. Financial Incentives by Govt needed to reduce burden of very high Capex of CG / CTL Projects and to improve Viability of ‘Energy Security’ Projects
D. Exemption from excessive Cess / Duties on Coal Feedstock prices
for stringent Environment Norms compliant CG / CTL Projects due to
Clean Technologies
E. Schemes for ‘Blending Methanol, DME with Gasoline & LPG’ respectively to
be implemented at the earliest
