Plasma gasification Plant


Plasma gasification can dispose of all types of waste has reached a maturity level. Prajwala BioEnergy can roll it out with confidence to deserving communities.This process significantly reduces waste volume whilst releasing a huge amount of energy as well as syngas

 

Plasma cracking is the latest technology for breaking the chemical bonds and destroy any kind of solid or liquid organic waste, PCBs (polychlorinated biphenyls), asbestos and hydrocarbons, some of which can be hazardous. Plasma gasification could be a generic process which may accommodate nearly any waste matter together with liquids, gases and solids, in any type or combination.". Moisture content is not a problem. The process provides substantially lower environmental emissions for both gaseous and slag by products than do current state-of-the-art technologies.

 

 

 

 

Benefits of this technology

 

Our range of systems include the following:

 

Waste volume reduction of Municipal Solid Waste, Biomass, Agricultural Timber Waste, Coal Fines, Used Motor Oil, Medical Waste and Low Level Nuclear Waste

 Beneficiation of waste products (Electricity production, synfuel production) generates handsome income that by far exceeds running costs.

Low emissions.

Low energy consumption, 2 to 5% of generated power usage.

Slag produced from inorganic waste is a sellable material as aggregate for roadbuilding, concrete etc.

Metals can be easily separated from slag and is a high.

Tipping charges per ton of waste increases profitability and reduces plant payback period.

 

 

Why Plasma Gasification?

 

Plasma gasification can convert materials, typically waste into energy and valuable product. Each town produces Tonnes of solid waste per day.. For example: A small town will produce 500 tons of Municipal Solid waste per day, while larger city would produce on average over 7000 tons of Municipal Solid waste per day. Most of the waste that’s discard from the homes and businesses on a day to day like non reusable plastics, construction scrap, used tires, household trash, and sewerage contains energy.Plasma gasification can convert all of this waste into electrical power, substitute gas, chemicals, transportation fuels, and fertilizers.

 

Plasma Gasification is Not Incineration

 

Incineration is that the burning of fuels in presence of oxygen rich atmosphere, wherever the material combust and produces heat and carbon dioxide, in conjunction with a variety of different pollutants.Plasma gasification which uses extraordinarily high temperatures in an oxygen starved atmosphere to fully decompose the input waste material into terribly simple molecules carbon monoxide, hydrogen and methane forming a syngas which can then be used for generating electricity or producing valuable products.

Plasma Gasification System

 

 

 

Plasma Gasification System exposes “feedstocks” such as municipal solid waste, industrial waste or biomass to temperatures over 10,000°C in an oxygen-starved environment to completely decompose input waste material into very simple molecules. The intense and versatile heat generation capabilities of plasma technology provides a plasma gasification/ vitrification facility to treat any type of waste streams in an exceedingly very safe and reliable manner. Dioxin and furans compounds aren’t formed in the syngas . The main two reasons are Firstly, the high temperatures inside the gasifiers, the process destroy any dioxin or furans. Secondly, the reducing environment precludes the formation of free chlorine from HCl, thereby limiting chlorination of any species in the syngas. The by-products of the process are a combustible gas and an inert slag. Plasma systematically exhibits lower environmental levels for both air emissions and slag leachate toxicity than alternative thermal technologies.

 

Decomposition of waste into energy rich fuel having High calorific value.

 

Because of the oxygen free environment and extreme high temperature,harmful compounds like furans, dioxins, NOx, or sulphur dioxide are not formed in the syngas within the gasifier.

 

Product gas is rich in CO, hydrogen and light hydrocarbons. The product gas contains substantial sensible heat, which is amenable for heat recovery to improve the efficiency of the electricity generation subsystem. A typical composition of this gas is 24–43% (v/v) H2, 25–44% (v/v) CO, 10–26% (v/v) CO2 and N2, depending mainly on the waste input composition. It is suitable for use as a fuel gas for turbines or gas engines.

 

Total replacement of petroleum fuel for the net energy output.

 

The slag is usable as aggregate, rock-wool, etc.

 

Large volume reduction, the slag is 1/250th of the volume of the processed solid waste.

 

No harmful emission or leachate.

 

Reduces need for landfill space.

 

Reduces risk of groundwater contamination from landfills.

 

Reduces transportation cost for waste disposal that needs to be shipped hundreds of kilometers/miles for disposal in the landfill
