"Transforming Waste into Value"

In some cases, the use of electric energy instead of fuel is cheaper, especially forplasmatrons of industrial frequency, due to the availability of a wide range of standard equipment of this type in the market. In case of autonomous installations of small capacity, the choice of electric energy eliminates the problems of delivery, storage and supply of fuel and improves the safety of the combustion process.

Diovis Eco is offering world-leading 3-phase AC plasma torch technology, developed and engineered by a team of highly renowned experts.

Those torches can be applied in a variety of high-temperature processes as a 
low-carbon alternative to conventional heating with fossil fuels.

PLASMA: In natural conditions, plasma is formed, for example, when earth's atmosphere is ionized by electric discharge, forming lightnings. A plasma essentially represents a gas heated to very high temperatures, in which the processes of dissociation (the decay of molecules into atoms) and ionization (the detachment of electrons from the outer electron shells of atoms) is taking place. Since the physical properties of plasma significantly differ from those of of gases, it is customary to call it the fourth state of aggregation of matter.

The high temperature characteristic for a plasma provides some distinct key advantage over traditional, lowertemperature, combustion-based thermal processes.

Traditionally, plasma is produced using special devices – plasmatrons. As a result of heat exchange, the carrier gas heats up to high temperatures. The resulting plasma can then be used to drive downstream equipment, such as gasification reactors.

POWER RANGE: 60-600 kW

PLASMA GASIFIER / GASIFICATION REACTORS 

A plasma gasifier consists of a reaction chamber in which the process of plasma gasification occurs. Plasma gasification is a thermochemical process in which the organic component of some feed material heated by a plasma jet is decomposed into a gaseous form, forming a combustible gas called syngas, consisting mainly of carbon monoxide CO and hydrogen H2. 

Syngas has a wide range of applications. It, for example, can be converted into ethyl alcohol, methanol, diesel fuel. Alternatively it can be burned to receive electric and/or thermal energy. Depending on the conditions and intended use, it requires gas cleaning such as the removal of solid particles, acid gases, heavy metals and other undesirable elements before further use. Inorganic constituents of waste such as metal, glass are removed from the bottom of the gasifier in a liquid molten state. The melt is quenched with water forming a glass-like material , which can be further used, for example, in civil or road construction. 

Our technology is unique, in the sense that it comprises a stand-alone process, which - if the energy for the plasmatron is produced from the syngas -allows one to completely abandon use of (potentially) expensive external energy sources. Plasma gasification is a widely applied and proven technology which solves many problems, maintaining a balance between waste disposal, energy production, reducing emissions of harmful greenhouse gases into the atmosphere and preserving the environment.

Utilization

This is not a combustion process,
so it doesn't have any corresponding polluting emissions
