Coal Gasification

Context:

In pursuance of the announcement made by the Finance Minister in the Budget speech on 1st Feb 2022 about “Four pilot projects for coal gasification and conversion of coal into chemicals required for the industry to be set up to evolve technical and financial viability”, the Ministry of Coal is organising a webinar on 4th March 2022,  wherein experts from Industry, Academia, Research organisations and Engineering Consultants along with practitioners and State Government officers and other stakeholders will join policy makers to deliberate the way ahead for effectively implementing the Coal Gasification Mission of Ministry of Coal

Process:

  • Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas.
  • This gas is then used instead of piped natural gas, methane and others for deriving energy.
  • In-situ gasification of coal – or Underground Coal Gasification (UCG)– is the technique of converting coal into gas while it is still in the seam and then extracting it through wells.

 

Production of Syngas:

  • It produces Syngas which is a mixture consisting primarily of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O).
  • Syngas can be used to produce a wide range of fertilizers, fuels, solvent and synthetic materials.

 

Significance:
  • Steel companies typically use coking coal in their manufacturing process. Most of the coking coal is imported and is expensive.
  • To cut costs, plants can use syngas, which comes from coal gasification plants in the place of coking coal.
  • It is primarily used for electricity generation, for the production of chemical feedstocks.
  • The hydrogen obtained from coal gasification can be used for various purposes such as making ammonia, powering a hydrogen economy.
