Proven Flash Calcination Technology

Calix is entering an exciting and dynamic phase in its plans to bring its technology to the marketplace. Specifically, Calix is targeting two major applications based on the one unique platform technology for calcining minerals. This technology presents two major business opportunities and applications.

CALCINED PRODUCTS

The first major application is relates to Calix’s flash calciner technology which can be used to calcine minerals. These calcined minerals may be used in building products, soil stabilisation products and fertiliser. The calcined minerals may include dolomite, magnesite, kaolin, bauxite or limestone.

Calix process is expose crushed minerals to superheated steam for a period of a few seconds in a continually feed shaft. The calcined minerals form useful products in many industries. The same calciner may be used for different minerals and generate new products.

One of Calix’s main products is Semidolime™, which is a product that can replace cement using calcined dolomite. The calcined dolomite produces less CO₂ emissions during its production and produces a good quality binding product.

Calciner System for Semidolime^TM Production

The ground Dolomite feedstock is injected into the Calciner tube (in blue) by a stream of superheated Steam. The dolomite solids are centrifuged onto the hot walls of the heat chamber (orange). The steam catalyses the breaking-up of the particles and the calcination reaction.

The energy for these processes is extracted from the walls of the Calciner Tube, which are heated from the Heat Chamber by combustion of a fuel in an external Heat Source. The processed solids formed during the drop through the Calciner tube are separated in an industrial Cyclone Separator, in which the Semidolime^TM is directed onto the Cyclone wall by the centrifugation action, and the product is then collected from the base of reactor. The gas, comprising CO₂ and steam, is ejected from the Cyclone by forming a counter-circulating vortex in the Cyclone Separator which rises upwards through the Exhaust Tube and is able to be captured for sequestration or re-utilisation.

ENDEX REACTOR

The second application is related to Calix’s Endex Reactor Technology, which can be used for improving fuel systems or improving carbon capture systems for power stations. This technology allows for conversion of natural gas or coal to hydrogen and CO₂. The CO₂generated by the process is uniquely captureable and is able to be sequested or sold. The hydrogen produced can be used in generation of electricity.

One important advantage of the Calix technology is that the Endex Reactor works on the pre-combustion side of the power reactor rather than the post combustion side of the power generator. As a result the Endex Reactor is much smaller than other systems of carbon capture from coal or natural gas power stations.
