CHP Environmental Benefits

Compared to avg US utility power

NOx Savings• 600kW with CHP

• 321 Cars Removed from the road

CO2 Savings• 600kW with CHP

• 438 acres of pine and fir forest equivalence


Integrated Heat Exchanger

• 21 Deg F Rise• Up to 480,000 BTU/hr

• 40 GPM Flow rate


Direct Heat

Capstone MicroTurbine and heat exchanger operating at a Pennsylvania plant


Exhaust Heat Utilization

• Preheat fuel gas to larger turbines or engines

• Preheat water to steam boilers or keep steam hot

• Direct heat to oil/water separators

• Supplemental heat to regas LNG or other liquid regas process

• Building or utility heat

• Various gas plant and amine plant applications

• Refrigerant based systems


Gas Pipeline Installations

Primary Compression Station Power with CHP

• Dominion Transmission, VA

• Three C30s provide prime power

• Exhaust heat for hot glycol

• Six other Dominion Transmission compressor stations currently run MT


Exhaust Heat Utilization

Microturbines also generate voluminous exhaust heat• (2) C30s providing 600,000 btu/hr at 530F

Heat from two C30s running on untreated wellhead gas goes to “heater/treater” separator


Gas Plant Processes

• Heat to glycol for• Dehydration process• Amine regenerator

• Direct heat to• Mol sieve in mercury removal• Fractionation train for

deethanizer


System DescriptionOrganic Rankine Cycle (ORC)

1. A pump circulates the working fluid through a heat exchanger, where it is exposed to the waste heat source.

2. That heat converts the working fluid from liquid into saturated vapor.

3. This vapor is then expanded across an expansion turbine, which is directly coupled to a high-speed generator (no gearbox).

4. The working fluid is then cooled, returning it to liquid state, where the cycle is then repeated.Existing Heat Sources
