There is no incineration or combustion of solid waste in the Taylor Gasification Process. Even with new, improved combustion technologies, processes based on direct combustion can achieve no more than a maximum process efficiency of 25%. A more typical efficiency for a direct combustion based system would be 20 to 23%. The Taylor Gasification Process provides an overall power generation efficiency of over 40%, by integrating the gasification process with a gas turbine-based, combined-cycle system. The Taylor Technology realizes nearly a 2 fold increase in power, compared to these conventional technologies in today’s marketplace.

Further, the Taylor Gasification Process is an improvement in productivity and value over similar biomass technologies, by providing in-situ conversion of condensable materials (tars) (a major issue in both synthesis and high efficiency power applications). The Taylor Gasification Process overcomes potential environmental issues by converting the incoming material into a combustible gas that can easily be cleaned to remove contaminants (e.g. nitrogen compounds, sulphur compounds, chlorine compounds, and particulates) prior to its end use.

The Taylor Gasification Process also features a unique gas conditioning step which, while converting the tars in the gas, increases the syngas hydrogen content, increases heat recovery, and simplifies downstream process operations. The gas conditioning step is integral to the circulating solids loop, and eliminates issues in conventional cleanup approaches such as cracking catalyst deactivation and integration with a separate downstream unit operation.

Summary of Our Enhanced Gasification Technology

Our patent-pending Taylor Gasification Process builds upon the results of existing technologies, but integrates critical and innovative, improvements that demonstrate critical advantages when compared with others developed to date. The Taylor Gasification Process:

♦   reduces issues with ash agglomeration, improving operation of the gasification system.

♦   provides in-situ destruction of condensable hydrocarbons, simplifying gas cleanup and improving environmental performance. The gas can be cooled prior to final cleanup, thus reducing the size of the cleanup equipment. This cooling also increases the ability to recover sensible energy in the product gas stream, improving overall process efficiency.

♦   is not based on starved air combustion, but uses a heat transfer material to indirectly heat raw biomass. Because no air or oxygen is added in the gasification reactor, no combustion reactions occur, providing environmental advantages, such as ready removal of chlorine from the synthesis gas and virtual elimination of ammonia (a NOx precursor) from the synthesis gas.

♦   employs a one-of-a-kind gas conditioning step to address the issue of tar removal, an exclusive feature of the Taylor Energy Solution. Compared to systems utilizing a separate, downstream tar removal step, the gas conditioning step enables the Taylor Gasification Process to realize up to a 40% improvement in recovered energy from the product gas.
