disposal, fly ash removal, and fouling avoidance. The OPTIMASH
project will firmly establish the sensitivity of the gasification
technology versus the coal characteristics and develop a
technology optimised for high ash coal gasification.
What is the role of the different partners in
this project?
CNRS-ICARE is leading the project under the co-ordination of its
director Dr Iskender Gökalp. ICARE is also contributing to the
gasification kinetics modelling and global gasifier modelling
including commercial scale up-scaling. ECN (The Netherlands
Energy Research Centre) is contributing to the assessment of
gasification technologies for high ash coals. ECN is also
conducting lab-scale experiments on coal gasification and
supporting the design of a 1MW pilot plant in India.
The OPTIMASH project started in
November 2011 and will continue
until the end of October 2015.
During this 48-month period, the
project mobilises a total of about
500 person months of research.
During the initial periods of the
OPTIMASH project, the full physical
and chemical characterisation of
the targeted Indian and Turkish
coals was performed and the
washability limits of these high ash
coals established.
Preparation and characterisation of the coal for its suitability to
gasification are performed by the Hacettepe University Department
of Mining Engineering, Ankara, Turkey, and TKI (Turkish Coal
Enterprises). They are also assessing the coal washability
characteristics and designing the optimum pilot coal washing
plant. The presence of Turkish partners in the project allows the
generalisation of the results to Turkish coals also containing high
ash. The Indian Institute of Technology Madras (IITM) is setting up a
high pressure lab scale circulting fluidised bed gasifier to validate
the CFD codes and to optimise the pilot scale gasifier design.
THERMAX Ltd is in charge of the design, manufacturing and
testing of the 1MW pilot gasification system operating up to 10
bars, to be installed in Pune, India.
What has been done since the project start?
The OPTIMASH project started in November 2011 and will
continue until the end of October 2015. During this 48-month
period, the project mobilises a total of about 500 person months
of research. During the initial periods of the OPTIMASH project,
the full physical and chemical characterisation of the targeted
Indian and Turkish coals was performed and the washability limits
of these high ash coals established. Gasification kinetics has
been investigated under various conditions and the development
of kinetics models have been conducted. Laboratory-scale
gasifiers are developed and tested.
The gasification technology of circulating fluidised beds with the
external combustion concept, has been selected for the pilot-
scale gasifier. The detailed engineering design of the pilot system
has begun. During the next phases of the project, the main
emphases will be put on the design optimisation of the pilot
plant, its manufacturing and intensive testing.
Exemplar project
We believe that OPTIMASH is an exemplary project regarding the
challenges that it tackles as well as the co-operation level it has
established between European and Indian R&D teams. The joint
efforts of CNRS, ECN, IIT Madras and Hacettepe University will
contribute effectively to the development of innovative gasification
technologies dedicated to high ash coals.
Moreover, the participation of THERMAX and the Turkish Coal
Enterprises in the consortium – representing two countries which
possess high ash coal reserves and have today to import large
amounts of expensive natural gas – provides a strong economic
incentive for the project.
