Ann: COLDry opportunities supported by Directors, page-19

From the annoucement;
:
A comprehensive process model of a gasification plant consuming lignite and producing hydrogen has been
developed by Monash University and ACI. ECT has initiated a work program with ACI to modify the process
model to replace the initial drying method (a steam-fluidised bed process) with the COLDry process.
.
The COLDry process shifts this balance considerably in two ways:
i) through consumption of gasification process waste energy, avoiding the need for additional
water-consuming cooling systems (capital saving, as well as improved site water balance), and;
ii) avoiding the need to consume high-grade or primary energy to generate the steam required to
dry the incoming lignite (reduced CO2 emissions requiring offset, reduced OPEX, etc).


While the study is yet to be completed, the Company is pleased to advise that the interim results confirm
COLDry achieved virtually complete conversion under a range of
conditions and is, therefore, an ideal feedstock for downstream
gasification processes like the one intended for the HESC project.
These results allow us to affirm COLDry as a relevant drying
process for downstream gasification.

Ashley Moore, ECT’s Group Engineer, commented:
“The early results from this study indicate almost 100% gasification
of incoming materials, indicating the highly reactive nature of
COLDry processed lignite.

“The impact of ECT’s process delivers huge reactive surface area to
a gasifier across the range of particle sizes investigated (212µm and 500µm).
“This fact then allows the gasification feedstock preparation system to consider less aggressive crushing
systems, reducing energy consumption while achieving high reaction rates and full conversion.
