Gasification Units

The IQ Energy Gasification process is a safe and controlled two-step process using high temperatures to produce gas from waste in an oxygen starved environment. These gases are then oxidised to produce heat. This process results in a cool, clean flue gas with negligible emissions and an efficient extraction of useful resources from the waste. The IQ Energy Gasifier converts dried organic content from the dryer into valuable resources, including heat to self-sustain the IQ Energy Indirect Dryer or for use in industrial or community heating needs. The IQ Energy Gasifier also produces other safe and clean resources, such as biochar and water, which has a use in agricultural or industrial purposes.

The IQ Energy Gasification unit can work with the IQ Energy Indirect Dryer or it can be paired with other dryer units currently commercially available.

Gasification - Inputs & Outputs

Gasification Input Examples

Biosolids/Sewage Sludge

Agricultural Wastes

Animal Wastes, e.g. Manures

Anaerobic Digestion Digestates

Screenings & Legacy Wastes

Mixed/Contaminated Organics, e.g. Food Waste

Mixed Residual Wastes

Other Wastes, e.g. Medical Wastes

Dried Waste (~15-20%MC)

Gasification Unit
Gasification Unit Output

Heat, can be used for:

- Drying
- Onsite Use, e.g. direct high temperature heat or hot water/steam production
- Power Generation, through ORC units

Biochar or Char/Ash
- Valuable for carbon sequestration
- Use within agriculture, industry or remediation

Hot Water/Steam
- Recovered water for industrial or agricultural use.

Additional Benefit Examples: Tonnage Reduction, Easier to Handle, Offset High Disposal/Trucking Costs, Offset Emissions and other additional benefits we can discuss.

IQ Energy Gasification Advantages

  • Unique ultra low turbulence Counter-Flow bed design
  • Process capacity ranging from 300 kg/hr up to 5000 kg/hr and higher
  • Delivers in two to three skids and assembles and commissions in days
  • All machinery is FAT tested before delivery
  • Destruction of contaminants, e.g. microplastics
  • Onboard NOx removal/SNCR – 2 sec @980C Retention – Full Enviro Skid/Scrubber/Quench/PM Removal
  • Capable of processing very high moisture content waste – up to 85% MC (with dryers)
  • Satellite Control (SCADA), monitoring, training
  • All controls and drivers included in onboard MCC

Further Advantage: Built-in Extended Retention Chamber to Target PFAS

When emerging contaminants, like PFAS, are present within a feedstock, then an extended retention chamber can be integrated into the gasification unit to achieve 980 degrees Celsius for a duration of 2 seconds in the gas phase. This ensures PFAS has been eliminated from the char product, but also eliminated within the gas phase. Sophisticated environmental emissions controls are also built into the unit to ensure any other contaminants can be eliminated. The commercial gasification unit moving onto a site in Alberta has this extended retention chamber built in.

Sizing

G300

Approximate Input: ~300 kg/hr (~2,300 tonnes/annum)

G500

Approximate Input: ~500 kg/hr (~3,840 tonnes/annum)

G1000

Approximate Input: ~1000 kg/hr (~7,700 tonnes/annum)

Generally the Gasifier Input is 80-85% dry solids (15-20% moisture content). Dry Solids can be lower than this and this can mean more waste can be run through the gasifier. Please feel free to reach out and we can model out what a project looks like for you. IQ Energy’s Gasifier Units can also come in other sizes that are not listed here.

Scaling a Gasification Project

The above is an example of how a project can scale with IQ Energy gasification and dryer units. The above is able to process ~110,000+ tonnes of Dewatered Sludge

(however, the above was for a potential client who was interested in ~70,000 Tonnes/Annum + redundancy)

Unit Examples

Commercial Gasification – Canada

G500 Unit with Extended Retention Chamber Targeting PFAS

  • Manufactured and cold commissioned completed in mid 2024
  • Moving to a site in Alberta, Canada.
  • This will be a commercial project with a local paper mill providing a consistent supply of wet pulp sludge which IQ Energy will transform into biochar.
  • IQ Energy will manage and operate the plant to facilitate the regular demonstration of various feedstocks, including those from potential customers. The feedstocks to be showcased will encompass biosolids, anaerobic digestion (AD) digestate, animal waste, and an opportunity to convert peat moss to activated carbon. Additionally, we will extend invitations to interested parties for both virtual and in-person site visits.

Demonstration Gasification – Canada

G300 Pilot Unit Demonstrated on Various Biomass Wastes

  • This unit was successfully piloted in Canada in 2019 as an advanced demonstration unit. Biomass feedstocks were run through the unit and a biochar product was produced.
  • This unit was sold to a third party in 2020.
