VOCGENTM CHP is an evolutionary new solution for environmentally regulated industries that require air pollution controls; providing more clean energy value and cost-savings than any solution in the CHP marketplace. 

 

The sensible use of high Btu value solvent emissions, known as VOCs, in a cogeneration system designed for industry is a pivotal technology solution for major sources of  regulated VOCs in the manufacturing, petrochemical and synthetic organic manufacturing industries and subject to Clean Air Act Title V operating permits.

 

VOCGENTM represents a significant  advancement in combustion chamber design for industrial gas turbines resulting in the ability to abate waste VOCs generated by industry.  The VOCs typically have high Btu energy value, resulting in beneficial recycled energy onsite.  This efficient onsite energy generation offsets purchased energy and traditional pollution controls resulting in a superior economic model by decreaseing costs and increasing savings and sustainable operations.  This remarkable solution achieves the environmental and energy efficiency goals of modern and advancing societies for industry. 

 

The Siemens single-shaft SGT-300 gas turbine combines advanced technology with a rugged industrial design.  It has a power output of 7.90 MWe and is available as a factory-assembled package.  The SGT-300 is designed to operate on a wide range of gaseous and liquid fuels and is equipped with a Dual-fuel Dry Low Emissions (DLE) combustion system, meeting the most stringent legislation for nitrogen oxides.

 

The commercially available SGT-300 VOC CHP solution can result in efficient and ecologically beneficial energy independence and security for industry and it offers an impressive return on investment. 

 

The economics involve attention to spark spread margins and emissions trading in states where programs exist, but notably rely on the elimination of the life-cycle costs of air pollution control equipment.  This is the key economic differentiator from typical combined heat & power and distributed energy (CHP/DE) projects.

 

The successful deployment of VOCGENTM will enable tens of thousands of manufacturing industries in the USA to re-tool their production processes with onsite energy systems, replacing legacy VOC burners including direct flame, RTO and RCO oxidizers.

  

 

 

 

 

Economic Benefits of Combined Heat and Power

Combined heat and power (CHP) can offer a variety of economic benefits for large energy users. The economic benefits of CHP can include:

  • Reduced energy costs: The high efficiency of CHP technology can result in energy savings when compared to conventional, separately purchased power and onsite thermal energy systems. To determine if CHP is likely to offer a compelling return on investment at a particular site, the costs of the CHP system (capital, fuel, and maintenance) should be compared to the costs of purchased power and thermal energy (hot water, steam, or chilled water) that would otherwise be needed for the site.

 

  • Offset capital costs: CHP can be installed in place of boilers or chillers in new construction projects, or when major heating, ventilation, and air conditioning (HVAC) equipment needs to be replaced or updated.

 

  • Protection of revenue streams: Through onsite generation and improved reliability, CHP can allow businesses and critical infrastructure to remain online in the event of a disaster or major power outage. Determining the economic value of CHP as backup power is explored in the white paper, Calculating Reliability Benefits.

 

  • Hedge against volatile energy prices: CHP can provide a hedge against unstable energy prices by allowing the end user to supply its own power during times when prices for electricity are very high. In addition, a CHP system can be configured to accept a variety of feedstocks (e.g., natural gas, biogas, coal, biomass) for fuel; therefore, a facility could build in fuel switching capabilities to hedge against high fuel prices.
