Gasification - Energy-Based Environmental Solutions

Gasification can produce heat, steam, and/or electricity from coal, renewable biomass resources or other by-products

Coaltec Energy's gasification system is able to run using a variety of fuel stocks, including the following:

• Coal - raw, washed and fines

• Dairy, Horse, Cattle and Hog Manure

• Poultry Litter

• Food Processing by-Products

We are proud to introduce Coaltec Energy USA, Inc. They are a solution-based company providing answers and resolution for businesses that have large quantities of by-products, biomass, or other fuel source available. Coaltec Energy’s business model is to integrate gasification technology into industry through conversion of available fuel streams or low-cost fuel to valuable energy (including heat, steam, and/or electricity). Through bottom-line project management and outcome-driven materials handling, our partnership with Coaltec Energy will enable business owners to concentrate on what they do best – their core business, without concern for by-product regulatory problems.

Coaltec Energy's commercial scale gasification test and demonstration facility centers around a modular-designed coupled gasifier.  It is located at the Coal Research Park of Southern Illinois University in Carterville, Illinois.  The system was primarily designed to demonstrate gasification and to test new fuels and combinations of fuels at a commercial scale.  

Alternate fuels that have been successfully tested include: cow manure, turkey litter, refuse-derived fuel, ethanol mash, corn stover, fine coal refuse, spent brewer’s grain, and paper sludge.  It is impossible to eliminate all of the risks associated with new applications of proven technologies.  However, the ability to test fuels and demonstrate the performance at a commercial scale minimizes those risks.  

Coaltec Energy's testing system includes a gasifier, oxidizer, and exhaust stack.  It is designed to produce a 2000+ degree flue gas for subsequent energy use.   The specially designed system is capable of gasifying all coals, a variety of biomass fuels, refuse-derived fuel, and wood debris, either individually or co-fired.  Commercial systems are designed specific to the fuel to be consumed.

The testing system has significant instrumentation including multiple thermocouples to allow monitoring of temperature in various stages of the reaction, as well as flow rate monitors.  Multiple sampling ports allow measurement of gas composition in the stack as well as between the gasifier and oxidizer.   Various gas analyzers are connected to provide gas composition information and emissions data.

Currently monitored are NOx, SOx, CO, and CO2.  Grab samples are collected and checked with a gas chromatograph.  The sampling system is being modified and upgraded to include testing for hydrogen as part of a project to determine the potential to generate hydrogen from various fuel sources.
