The HTCW Gasification Process

HTCW Process HTCW Process Diagram

Ideally, industrial-scale waste processing should result in:

  • no or minimal pre-treatment
  • optimum volume and mass reduction
  • destruction of hazardous materials
  • utilization of all waste as a resource
  • optimum energy potential utilization
  • produce no or negligible residues for safe disposal

The HTCW gasification process meets these standards by its efficient thermal and chemical transformation of highly diverse waste materials into gas, energy and value products without adverse environmental effects.

Feed material (waste) needs only minimal preparation. Objects size must be adjusted to the inlet of the HTCW reactor (~ 500 mm). No pre-sorting or shredding is required. Any metallic or mineral content is in fact advantageous to the process. Depending on the composition of the feed material, additional materials such as coke and limestone are added as needed.

The various high-temperature melting gasification stages transform the physical and chemical characteristics of the feed material and thus volume is reduced. Synthesis gas, metals and hard crystalline stone are produced by the process, all of economic value. More on Output ... >>>

The organic components descending down the furnace shaft are subject to a controlled pyrolytic decomposition and a gas is formed. This pyrolysis gas is fed into the high-temperature area. There it becomes a gasification agent with the aid of injected oxygen. With reaction temperatures between 1500 and up to 2,500°Celsius the organic compounds are decomposed into low-molecular substances. What sets HTCW apart is its net efficiency, i.e. the net energy yield available for supply to an energy customer. More on reactor principle ... >>>

With the destruction of organics and the by now concentrated non-organic materials turned inert, the hazardous components are destroyed. The 1-3% remaining slurry of concentrated dusts require disposal.
