Waste Gasification Systems
We help to create best practice selection criteria and processes for overall plant concept, technology and system to project owners and developers that prefer sales independent, qualified engineering consulting and turnkey contractors and suppliers that want to expand their scope of supply.
Creation of Syngas under low or now Oxygen
There are many different systems with their specific pro's and con's in the market. There is no proven system, an no plant proven technically and commercially feasible to convert wet, unsorted Asian MSW to energy. Very to the contrary most of the attempts to do so failed, with unsorted MSW, RDF and biomass.
Gasification puts high requirements on the feedstock. Dried organic parts of MSW incl.crude oil products need to be dried below 25% moisture content, to be converted to synthesis gas, syngas, a gas with similar energy content than biogas and able to run gas engines for electricity. In most systems mineral inert, glass, metals have to be removed. Material need to be fine shredded to < 50mm. s such as low quality, wet or bituminous coal, sludge, peat, shale and waste. Has a high power efficieny and low, guaranteed volume to landfill. Does not need grate cooling, comes with dry scrubber (no water consumption) and air fan cooled closed cooling water system. We see this system as solution for the huge small scale 1-5MW market, offgrid using pre-treated waste or biomass.
Pyrolysis
This is a technically mature and proven thermochemical process to decompose complex long chain organic compounds into their original material: light crude oil, so called Renewable Fuel Oil (RFO). Materials suitable are plastics and rubber. While many cement companies convert their scrap tires to RFO to fuel trucks, projects to reconvert MSW plastics to marketable 'diesel' are small scale or have failed altogether. As only waste plastics can be converted to revenue (RFO), it is not a viable core technology for MSW treatment.
Oxygen starved Stages of Direct Combustion
Indirect combustion technologies like Gasification and Pyrolysis convert waste to syngas or recovered fuel oil under oxygen starved or even oxygen free conditions. Then these gases are burned with oxygen for power. This must not be confused with engineered or spontaneous oxygen starved or even oxygen free phases in direct combustion sometimes also referred to as 'pyrolysis' or 'gasification'.
