Our Technology

Plasco employs a patented process that efficiently recycles heat from the process to gasify the waste and then uses the unique characteristics of plasma to refine the gaseous products into a clean, consistent syngas.

 
 

Our Technology

Plasco supplies the core conversion technology in Energy from Waste Plants by delivering a patented process for the conversion of waste material into synthetic gas and marketable products. Plasco efficiently recycles heat from the process to gasify the waste and then uses the unique catalytic characteristics of plasma to refine the syngas into a clean, consistent fuel.

A decade of technology development and plant operation, with over $400M and 1.2M man-hours has allowed Plasco to bring a versatile process to market. The Integrated Conversion And Refining System (ICARS) has been designed with a highly flexible configuration to suit the plant footprint. Plasco provides the design and specifications package for the Gas Quality Control Suite (GQCS) to ensure the energy rich fuel gas meets engine requirements.

Each ICARS will process 200 tonnes per day of municipal solid waste. Larger plants can be built using multiple 200 tonne per day modules with no scale up. Multiple modules also increase system availability. ICARS is adaptable to a wide range of hazardous and non-hazardous fuels of varying compositions and moisture.

ICARS receives shredded waste into the feeder system, moving the waste into the converter vessel where the waste is dried and the volatiles separated, using recycled heat. The waste is moved through the gasification process by the patented horizontal bottom grate. Fixed carbon in the waste is further heated to release the CO while heating inert material to melting point. The inert material is further treated to create a vitrified and non-leachable slag suitable for sale.

The syngas passes through cyclones to remove particulate. Air or oxygen is then added before the syngas is exposed to the plasma plume. Plasma catalysis is used to refine the syngas by cracking long chain molecules, resulting in a low-tar syngas that once cleaned and cooled is suitable as a fuel. Plasma is used as a catalysis: not a primary source of heat.

ICARS is manufactured to Plasco specifications.

ICARS-GENERAL-ARRANGMENT

The GQCS is specific to the Plasco syngas. The design and specifications are done by Plasco, while the supply of components is by third party suppliers and installed by third party contractors. The GQCS produces a clean, dry, cool syngas fuel suitable for IC engines or gas turbines.

Plasco provides GPRS installation and commissioning oversight.

 

 

Economies of scale for capital and operating costs generally occur at 600TPD and above


ICARS is an efficient use of energy creating an industry leading net recovery of energy in the waste processed of about 75%
