Pre-Conference Masterclass

Monday 31 May 2010, 8:30am-5:00pm

Adding Value to Coal - Coal Conversion to Fuels & Chemicals
Led by : Dr. Duncan Seddon , DUNCAN SEDDON & ASSOCIATES PTY. LTD

A consultant to the oil, gas and petrochemical industries, he has been involved with the production and use of transportation fuels and commodity chemicals for over 30 years. He has a particular interest and expertise in clean fuels, the use of gas derived chemicals in the transport fuel sector and in Gas to Liquids technology and processes. He is a Fellow of the Royal Australian Chemical Institute and a Member of the Society of Petroleum Engineers.


Synopsis:

The continued concern with the long term supply of crude oil, the demand for clean fuels and the ubiquitous availability of coal is focusing interest in
the conversion of coal into liquid fuels. The course gives a technical and economic assessment of the major routes for conversion ranging from gasification
to pyrolysis and hydrogenation routes. 

The Workshop is in 8 Modules
     

1. The Need & the Problem

  • Drivers for clean fuels
  • Gas supply
  • Crude oil supply
  • Problems with conventional approaches
  • Coal availability

2. Chemical Intermediates

  • Coal gasification
  • Proprietary gasifiers
  • I mpact of coal properties (rank, ash, sodium) on gasifier selection
  • Relative performance
  • Production economics
  • Water gas shift and acid gas removal

3. CTL - The Fischer-Tropsch Process

  • FT prior to 1980
  • Approach to maximising diesel
  • Modern commercial plants - Sasol, MossGas, Shell, Qatar
  • Next generation plants
  • Product quality
  • Process economics

4. Coal to SNG & LNG

  • SNG production technology and costs
  • Comparison of SNG and Coal Seam Gas with Natural Gas
  • LNG production methods and costs
  • Storage, transport and re-gasification
  • Comparing LNG with CTL
  

5. CTL via Methanol & Derivatives

  • Technology for production of methanol
  • New technology for the production of DME
  • Coal to gasoline via methanol
  • Coal to olefins via methanol
  • Coal to plastics

6. Alternative Technologies

  • Underground coal gasification
  • Coal pyrolysis routes
  • Coal hydrogenation
  • Comparison of the hydrogenation route to the gasification route
  • Coal to ammonia
  • Coal to acetylene to chemicals

7. Greenhouse Mitigation & Mitigation Costs

  • The Kyoto Protocol
  • Carbon emissions from CTL, GTL and LNG
  • Emissions trading and carbon taxes
  • Geo-sequestration and sequestration costs
  • I mpact of carbon costs on process economics

8. Critical Comparisons

This session presents cases studies for the conversion of hypothetical coal reserves. The process economics for alternative approaches will be developed and critical compared - SNG, Power, FT Diesel, Methanol and Gasoline.
