MIP Gasification – Technical


Gasification diagram
1. Waste or fuel is shredded to reduce particle size and promote feedstock homogeneity.

2. Waste is transmitted via a screw conveyor to the MIP Gasifier. In the MIP Gasifier, low oxygen conditions and high temperatures reduce long chain organic molecules into a mixture of hydrogen and carbon monoxide, known as Synthesis Gas (syngas). Ash is removed to an ash bin.

3. The syngas is passed through sand and carbon filters to remove impurities and tars.

4. The cleaned syngas can be used for heat and power generation using a gas engine, a gas turbine or fuel cell. The exhaust gases (principally carbon dioxide and steam) are vented to the atmosphere.

Principle Technical Advantages

The principle technical advantages of the Plasmergy process compared to existing gasification and plasma gasification technologies are:

The plasma are generated from microwaves, and unlike their direct current equivalents, the torches have no corrodible parts which results in an increase in operational lifespan whilst reducing plant OPEX costs.

The microwave plasma plumes operate at >1000°C and enable the efficient gasification of solid fuel without the requirement of an oxidant. The clean, undiluted syngas generated is of high quality, ideal for energy generation via gas engines, gas turbines or fuel cells.

The plasmas are self-striking and immediately deliver the high temperatures required to thermally dissociate the feedstock, unlike conventional gasification technologies which have long and labour intensive start-up procedures.

The high gasification temperature and intensity of the plasma plume leads to an almost complete fuel conversion, minimising waste, and increasing fuel efficiencies.

The technology is commercially viable at smaller scales and requires relatively few components. A complete power generation system can be self-contained within a single transportable 'plug and play' modular unit enabling both decentralised heat and power generation and rapid integration within existing heat and power networks.

On-going Developments

Through collaboration with leading technology companies and academic institutions, Plasmergy is currently engaging in a development programme that will see the MIP Gasification technology fully integrated with a solid oxide fuel cell (SOFC), such that there is a much greater interaction in energy flow and usage between the two elements to maximise power conversion efficiencies.

Through maximising the energy conversion efficiency of Plasmergy's MIP Gasification technology, through integration with gas engine and fuel cell technology, achievable revenues per tonne of waste treated are expected to be significantly higher than those achieved by conventional waste management practices.
