1. Thermolysis / Gasification

Enispect favours modular systems that can process various quantities of waste depending on the needs (from 2 tons of waste per hour).

Enispect offers solutions based on the latest technological advances in reactor design and catalyst development; whether the produced syngas is intended as generator/boiler fuel or for the production of green hydrogen.

Advantages to our approach include:

Lower capital costs
Well tested/commissioned systems at the manufacturing facilities of the technology providers, before delivery to project sites
Faster engineering design and project construction times
Expandability

Products of Thermolysis / Gasification

T/G produces:

Biochar: - A nutrient rich, inert and ash-like solid material; and may be used as a soil conditioner

SYNGAS

Syngas (short for synthesis gas) is a gas mixture of 30 to 60% CO, 25 to 30% H2, 5 to 15% CO2, and 0 to 5% CH4. Studies have shown that the temperature, pressure and use of catalysst can favour syngas production, minimising biochar and bio-oil production.
The temperature of the freeboard space of the T/G reactor (the large space above the dense bed surface where the solid density is low compared with dense phase), in combination with the use of specific catalysts, has a direct impact on the proportion of H2 & CO in syngas.

2. Conversion of plastics and organic materials to green fuels/energy

Latest technologies – more efficient, lower costs, applicable to food waste, plastics and other non-toxic organic materials (including wastewater treatment sludge, agricultural slurries etc.).

Based on the principle of thermolysis (thermochemical gasification –organics naturally breakdown into simpler organics when exposed to high temperatures in the absence of oxygen).

Breaks down organic materials into a synthetic gaseous fuel with Hydrogen and carbon monoxide being its main components

May be used directly as generator/boiler fuel to produce electricity or heat (or both) or,
Hydrogen may be separated as a green fuel with hydrogen demand increasing fast as it is being recognised more and more as the fuel of the future.

3. Biogas Plants

Anaerobic digestion (AD) is a biological process where volatile organics is biodegraded (digested) in an enclosed tank/reactor under anaerobic conditions (i.e. in the absence of oxygen), resulting in the production of a gas mixture (biogas) of methane (CH4) and carbon dioxide (CO2). Biogas is similar to natural gas, with the main difference being the proportions of CH4 and CO2, being typically 55%-70% CH4 and 45%-30% CO2., with natural gas having a much higher proportion of CH4 (>85%) and of course a lower proportion of CO2.

With the latest technology advancements, it is today possible to upgrade biogas to be very similar to natural gas.

AD can be used for processing any volatile organic matter, including food waste, biological sludge and livestock waste (e.g. poultry farms, pig farms, cattle farms, etc.) in many countries of the world.

Biogas plant

It is estimated that more than 5 million biogas plants are currently operating around the world, majority of which are small low-tech systems, but with several large scale high-tech systems also in operation.

AD is considered as one of the best available techniques (BAT), as it is an efficient renewable energy technology and highly reliable.

Uses of Biogas

In most cases, biogas is used as an alternative green fuel for heat or electricity. For instance, in China where there are hundreds of thousands of small low-tech systems in operation, where the gas is used for cooking and heating of homes. On the other hand, biogas produced by large high-tech AD systems, is used a generator fuel to produce electricity and heat (cogeneration).

Biogas can also be broken down to H2 and CO, by steam reforming (a specialised version of the thermolysis process).

Advantages of AD

The most notable benefits of AD are outlined below:

Solves the problem of volatile organic waste in a sustainable and environmentally friendly manner.
Significantly reduces methane, carbon and foul odour from waste, improving the human environment.
Economic benefits, job creation, renewable energy.
Significantly reduces the carbon footprint and the environmental image of waste producers
